Android Java How To Stop Activity From Opening Twice Programatically

The NativeScript Metadata is the mapping between the JavaScript and the Android world. Besides a full list with all the available classes and methods, the metadata contains the JNI signature for each accessible Android method/field. It is pre-generated, in a binary format, and embedded in the application package , storing the minimal required information thus providing small size and highly efficient read access. The generation process uses bytecode reading to parse all publicly available types in the Android libraries supplied to the NativeScript project. The generator works as part of the Android build process, meaning that no user interaction is required for it to work.

Fragments can be used to respond to user input, varying form factors and other issues, such as, the orientation of the device. In portrait mode an app may show itself in a different manner to say landscape. The FragmentManager is responsible for adding, replacing, removing fragments dynamically. In this lecture, we will use the case study of the Fragment App to best understand how code can build dynamic layouts and respond to these types of events. This is the "top-level" fragment, showing a list of items that the user can pick. Upon picking an item, it takes care of displaying the data to the user as appropriate based on the current UI layout.

Displays a list of items that are managed by an adapter similar to ListActivity. It provides several methods for managing a list view, such as the onListItemClick() callback to handle click events. The fragment uses a helper function to show details of a selected item. This includes configuration of INDEXED_EXTRACTIONS and any other parsing, filtering, anonymizing, and routing rules. Performing these actions on the instance that indexes the data will have no effect, as the forwarded data must arrive at the indexer already parsed.

Being two different worlds, Java/Kotlin and JavaScript use different data types. For example java.lang.String is not the same as the JavaScript's String. The NativeScript Runtime provides implicit type conversion that projects types and values from JavaScript to Java and vice-versa. To create a deep link to your app's content you first have to create an intent filter. An intent filter specifies the types of intents the activity would like to receive.

The 'Back' button has many different uses in many different android apps. While some app developers use it to close their apps, some use it to traverse back to the app's previous activity. Many apps require the user to press the 'Back' button two times within an interval to successfully close the application, which is considered the best practice.

So it is a good practice to exit from an app with a double click of the back button. As some time user can press the back button by mistake. So, to ensure that, whether the user really wants to exit from the app we implement this feature. To forward this data to another Splunk instance, edit inputs.conf and props.conf on the forwarding instance, and props.conf on the receiving instance.

For information on how to set source types when importing structured data files, see The "Set source type" page. Pearson automatically collects log data to help ensure the delivery, availability and security of this site. Represents a thin wrapper over a class or an interface and provides access to its methods and fields. From a JavaScript perspective this type of proxy may be considered as a constructor function. What happens when an application is built with higher API level(e.g. 23), but runs on a device with a lower API level(e.g. 20)?

PropertyTypeDescriptiongetDownloadUrlStringA URL that can be used to download the object. This is a public unguessable URL that can be shared with other clients. After the upload completes, this is the metadata returned by the server.getTaskUploadTaskThe task that created this snapshot.

This metadata contains typical file metadata properties such as name, size, and contentType . The putFile() method automatically infers the MIME type from the File extension, but you can override the auto-detected type by specifying contentType in the metadata. If you do not provide a contentType and Cloud Storage cannot infer a default from the file extension, Cloud Storage usesapplication/octet-stream. See the Use File Metadatasection for more information about file metadata.

We'll have to modify the createNotification method we defined earlier. We need to create another PendingIntent that'll start the activity that'll be shown on the lock screen. It's also important to add a category such as ALARM or CALL for increasing the chances of it appearing on the lock screen. As the logic in the activity depends on the scenario (single/multi pane), you typically write a check to determine in which mode you are. One way is to define a configuration file in the values resource folder. The key / value pair defaults to false and a additional configuration file set this value to true for the desired screensize.

In theonCreateView()method the fragment creates its user interface. Here you can inflate a layout via theinflate()method call of theInflatorobject passed as a parameter to this method. Use one activity, which displays two fragments for tablets and on handset devices. In this case change at runtime the fragments displayed by the activity whenever necessary. In this scenario you typically define instances of the FrameLayout class as placeholder in your layout and add the fragments at runtime to them.

This feature is mostly used in all over android apps at present time because this feature gives us the ability to re program the android back button so you can define certain task upon it. So here is the complete step by step tutorial for Clicking twice the back button to exit activity in android. In this launch mode a new task will always be created and a new instance will be pushed to the task as the root one.

If an instance of activity exists on the separate task, a new instance will not be created and Android system routes the intent information through onNewIntent() method. It creates a new instance of an activity in the task from which it was started. Multiple instances of the activity can be created and multiple instances can be added to the same or different tasks.

In other words you can create the same activity multiple times in the same task as well as in different tasks. A task is a collection of activities that users interact with when performing a certain job. In general an application contains number of activities.

Normally when user launch an application a new task will be created and the first activity instance is called root of the task. This post has shown you examples about how to close the fragment by a close button in android and also how to disable coming back to activity android studio. On the receiving instance, use the Search app to confirm that the fields have been extracted from the structured data files and properly indexed. Before Splunk software displays fields in Splunk Web, it must first extract those fields by performing a search time field extraction. By default, the limit for the number of fields that can be extracted automatically at search time is 100.

While Splunk software has indexed all of the fields correctly, this anomaly occurs because of a configuration setting for how Splunk software extracts the fields at search time. By default NativeScript includes all supported entities in the metadata. This allows app and plugin authors to freely call any native API from JavaScript. While it is benefitial during development, in some cases having metadata for all the APIs is undesirable. This means that you can't access a JavaScript value/object from both threads. You can only serialize the object, send it to the other thread and deserialize it there.

This is what postMessage() function is responsible for. You can access a native object from more than one thread, without copying it, because the runtime will create a separate JavaScript wrapper object for each thread. Keep in mind that when you are using non-thread-safe native APIs and data you have to handle the synchronization part on your own.

The runtime doesn't perform any locking or synchronization logic on native data access and API calls. Onerror - handle uncaught errors occurring during execution of functions inside the Worker Scope . If the handler returns a true-like value, the message will not propagate to the Worker instance's onerror handler on the main thread. After onerror is called the worker thread, execution is not terminated and the worker is still capable of sending/receiving messages. Once the changes are made to the FragmentTransaction, commit() is called for the changes to take effect. The fragment saves its current dynamic state, so it can later be reconstructed in a new instance of its process is restarted.

If a new instance of the fragment later needs to be created, the data you place in the Bundle here will be available in the Bundle given to onCreate, onCreateView, and onActivityCreated. In the code the new fragment restores the state in onActivityCreated(). In portrait mode the application will replace the existing titles fragment with the details fragment if the user taps on one of the names in the list view . We will come back to discuss how this is done in the code in a moment. Essentially there are two activities and two different fragments used to implement this when the code runs in portrait mode; these activities are FragmentLayout and DetailsActivity. This article helps every android application development company like us Moon Technolabs.

IPhone app development improves requirements but android app development competes with clients' requirements in a short time. Here described issues are going to be more helpful for my developers. Very helpful and informative post to understand the development things which should consider during android application development. Most of the android app developers make mistakes during programming and not using the fragment is common in all. Thanks to updating to us with helpful things to keep in mind we will implement in our recent project. This is very special launch mode and only used in the applications that has only one activity.

It is similar to singleTask except that no other activities will be created in the same task. Any other activity started from here will create in a new task. If an instance is not present on top of task then new instance will be created. To use Splunk Web, follow the instructions in Use Splunk Web to extract fields from structured data files earlier in this topic. Specify the structured data file that you want the software to monitor. It sets the source type of the data based on its interpretation of that data.

For example, if you upload a CSV file, it sets the source type to csv. Core Foundation has the concept of Toll-free bridged types - data types which can be used interchangeably with their Objective-C counterparts. When dealing with a toll-free bridged type NativeScript always treats it as its Objective-C counterpart. Core Foundation objects on the toll-free bridged types list are exposed as if they were instances of the equivalent Objective-C class. This means that a CFDictionaryRef value in JavaScript has the same methods on its prototype as if it were a NSDictionary object.

The source code of application.android.ts is bundled separately as application.js file which is loaded from the native Application.java class on launch. The screen shows a product with an image, name, brand and price. Since everybody loves promotions you're going to use deep links to add functionality to apply discounts to the product. In addition to that you can use the setRetainState method call on the fragment.

This retains the fragment instances between configuration changes. It only works if the fragments are not added to the backstack. The FragmentManager class allows you to add, remove and replace fragments in the layout of your activity. It can accessed in an activity via the getFragmentManager() method. Activity and fragment instance have been created as well as the view hierarchy of the activity.

At this point, view can be accessed with thefindViewById()method. After you enable Safe Args, the plugin generates code that contains classes and methods for each action you've defined. For each action, Safe Args also generates a class for each originating destination, which is the destination from which the action originates. The generated class name is a combination of the originating destination class name and the word "Directions". For example, if the destination is named SpecifyAmountFragment, the generated class is named SpecifyAmountFragmentDirections.

The generated class contains a static method for each action defined in the originating destination. This method takes any defined action parameters as arguments and returns a NavDirectionsobject that you can pass to navigate(). The fragment lifecycle ensures that onCreateView() to build the layout for the fragment.

It builds the fragment with a textview -- text.setText(Shakespeare.DIALOGUE[getShownIndex()]) -- and attaches it to a scroller and returns the view which is drawn. The end of this thread is the drawing of the details fragment by the new activity as shown below. Assume in the path through the onCreate() for the activity that its the first time through the application/activity running. We first create a new fragment , set the index for the item selected and the we use the programmatic approach to adding the fragment. But, if you are starting fresh and trying to create a beautiful experience for your users, do consider eliminating the past.

Sharing content, taking pictures, recording video, picking contacts, adding events, opening links with native apps, etc. The java.lang.Thread.run() method is called if this thread was constructed using a separate Runnable run object, else this method does nothing and returns. This configuration indexes all extracted fields from the splunk_resource_usage source type that begin with the string data..

This is the format for a source-type-scoped custom indexed field configuration. It uses a wildcard expression to target a set of fields that have been extracted from structured data. Then the method returns this combined View, with the ViewGroup as the root. When attachToRoot is false, the layout file from the first parameter is inflated and returned as a View.

The root of the returned View would simply be the root specified in the layout file. In either case, the ViewGroup's LayoutParams are needed to correctly size and position the View created from the layout file. To have access and Intellisense for the native APIs with NativeScript + TypeScript or NativeScript + Angular projects, you have to add a dev dependency to @nativescript/types. More details about accessing native APIs with TypeScript can be found (#intellisense-and-access-to-native-apis-via-typescript). One of NativeScript's strongest capabilities is the access to Android (also referred to as 'Java/Kotlin' or 'native') APIs inside JavaScript/TypeScript. First, copy in the SmartFragmentStatePagerAdapter.java which provides the intelligent caching of registered fragments within our ViewPager.

Baby Died From Lack Of Attention

A very common grief reaction after perinatal or SIDS death of an infant is intense preoccupation with thoughts and images of the dead baby. According to several studies, between 65 and 95 percent of mothers and 51 and 85 percent of fathers report problems with preoccupation or irrational thoughts about their dead baby during the acute phase . Many parents report a sense of the baby's presence—of hearing their dead baby cry—and some mothers say they feel fetal movements for months after the delivery. Others report illusions or hallucinations that their baby is still alive.

This can be disconcerting to parents and family members; however it is reported in studies of many bereaved parents. Like many other traumatic events, the death of an infant challenges parents' assumptions about their own and their families' safety in the world. Anger and irritability about the injustice and unfairness of losing their child are common grief responses and may be directed toward health care professionals, their spouse, God, or fate. Alternatively, these may be emotions directed inward toward themselves resulting in lowered self-esteem, self-blame, and depression. Parents also experience intense anger and jealousy toward other parents who have living babies. The authors found that many breastfeeding mothers and caregivers do sleep with their infants whether intentionally or unintentionally.

Deaths are less common among older children than among infants, with accidents, especially among adolescents, the most frequent cause. Cancer is the leading illness cause of death in children and adolescents. Parents who experience the death of an older child usually have many of the feelings already discussed in relation to infants.

However, more is known about the grief of parents of children who die of an illness than about the grief of parents whose children die suddenly by accidents, homicide, suicide, natural, or man-made disasters . Retaining parents in need of assistance who have experienced sudden death in formal longer-term bereavement services remains a challenge . These organizations have been the focus of significant studies on the services they provide to parents .

4.A family and interpersonal focus is essential, whether the primary target of the intervention is the parent or the child. The parents' management of their own grief and construction of the meaning of the loss has an enormous impact on surviving children. Similarly the parents' own positive mental health and ability to fulfill important life goals going forward contributes to a stronger support system for surviving siblings. Trauma theories and grief theories developed in separate literatures, and only recently has research begun to integrate the findings, concepts, and responses related to these overlapping but distinct conditions [45–48]. Grief therapies have also been found effective in situations of complicated grief, of which traumatic grief is one example .

A failure to address the intertwining of these symptoms of trauma and loss early in their bereavement may compromise the individual's capacity to experience optimal recovery. For example, cognitive behavioral interventions suggested for trauma symptoms in a treatment manual by one research team include stress inoculation therapy, gradual exposure, and cognitive processing. Gradual exposure aims to separate overwhelming negative emotions such as terror, horror, extreme helplessness or rage from thoughts, reminders, or discussions of the death of the loved one. Cognitive processing aims to identify, correct, and challenge thoughts about the death that are unhelpful or inaccurate (for example "my dad must have suffered terrible pain during the explosion in the WTC").

Nader describes convincingly how trauma prevents reminiscence necessary to grieve by evoking feelings of terror . Conversely, grief can also act as a traumatic reminder to the individual who may be experiencing a sub-clinical response to trauma or meet criteria for a formal diagnosis of PTSD, increasing anxiety in either situation. Those bereaved by deaths seen as nontraumatic are more apt to focus on their relationship to the deceased as an important feature of the experience of loss . The death of a child of any age is a profound, difficult, and painful experience.

While bereavement is stressful whenever it occurs, studies continue to provide evidence that the greatest stress, and often the most enduring one, occurs for parents who experience the death of a child [1–6]. Individuals and families have many capabilities and abilities that allow them to respond to interpersonal loss and to emerge from the experience changed but not broken. The few studies that have compared responses to different types of losses have found that the loss of a child is followed by a more intense grief than the death of a spouse or a parent . This conclusion must be considered cautiously, however, since these studies have typically confounded sample differences in age and degree of forewarning . Forewarning is important because according to the Centers for Disease Control and Prevention , about half of child deaths occur during infancy, most with limited preparation time.

Unintended injuries are the leading cause of death in children age 1 to 14 and account for more than half of all deaths among young people 15 to 19 years of age. In addition, while the overall death rate for children aged 14 and younger has declined substantially since the 1950s childhood homicide rates have tripled and suicide rates have quadrupled . Perinatal grief is framed within a social context in which a perinatal death is not recognised as the death of a baby . Research shows that after a perinatal death, parents receive inaccurate information too late and receive inappropriate comments from healthcare professionals .

In Spain, unlike in other countries, there is no standardised care for families suffering perinatal grief, with a great variability of care in daily practice for mothers and fathers who suffer the death of their baby . In general, parents of infants who have died from whatever causes share the experience that their friends and family do not know their infant, that they may not recognize or empathize with the full extent of their loss . Many parents of infants who die report being particularly stressed by people who avoid any discussion of the loss or offer clichés or dismissing statements such as "you can have another child". The advice to have a new child as a way of bypassing or avoiding the pain of loss for the particular child who died remains controversial because findings from research are contradictory . Friends as well as other family members may be impatient about the "slow" rate of parents' recovery from the loss.

As in most forms of bereavement, depressive feelings are often present following this type of loss. In fact, bereaved parents have been found to experience elevated symptoms of depression more than two years following perinatal death of their child . Therefore interventions that provide practical and emotional support, skills training, and respite throughout the often long and crisis-filled period of the child's illness may aid families' bereavement. The vast majority of newborn deaths take place in low and middle-income countries. In settings with well-functioning midwife programmes the provision of midwife-led continuity of care can reduce preterm births by up to 24%. MLCC is a model of care in which a midwife or a team of midwives provide care to the same woman throughout her pregnancy, childbirth and the postnatal period, calling upon medical support if necessary.

With the increase in facility births (almost 80% globally), there is a great opportunity for providing essential newborn care and identifying and managing high risk newborns. However, few women and newborns stay in the facility for the recommended 24 hours after birth, which is the most critical time when complications can present. In addition, too many newborns die at home because of early discharge from the hospital, barriers to access and delays in seeking care. The four recommended postnatal care contacts delivered at health facility or through home visits play a key role to reach these newborns and their families.

That's the approach in the United Kingdom, where maternal deaths are regarded as systems failures. Coroners also sometimes hold public inquests, forcing hospitals and their staffs to answer for their mistakes. There is no way of protecting children from the fact of the death and the resultant distress and grief of the parents and other family members. Children are astute observers of behavior, especially the behavior of their parents.

They need to know why parents are behaving so differently now. Children do notice the grief and depression of adults around them. Some of the tears, grief, and pain of the parents should be shared with them and they need opportunities, when ready, to share their own sad and often times scary feelings.

They need to grieve with the family by being given opportunities to be involved in funeral and grieving rituals. When the child's death can be anticipated, evidence suggests that effective management of the terminal illness period may also benefit the family's bereavement. Wolfe also found that families may be helped during this highly stressful period by mental health interventions. Complicated grief in adults refers to bereavement accompanied by symptoms of separation distress and trauma .

These symptoms must have lasted at least six months and led to significant functional impairment. Because parents of children who die are at greater risk for traumatic stress symptoms and emotional dysregulation, they are at greater risk of complicated grief . Integrating the loss of a child into the life narrative, making sense and new meanings of such a wrenching event, presents a challenge to parents and family . Although once common, deaths of children between the ages of 1 and 14 now account for less than 5 percent of all deaths in the United States; about 57,428 infants, children, and adolescents died in 1996. In contrast to the past when families might have had several children die, death in childhood is now rare.

Conflicting with current life-cycle expectations, the death of a child may be experienced as the death of the parents' future dreams as well as creating a profound change in their present roles and functioning. Increases in the incidence of suicide and homicide in adolescents and random acts of violence in our society have increased the risk of traumatic stress responses for bereaved family members. The objective of this study was to describe and understand the experiences and feelings of mothers and fathers who have suffered a perinatal death. The study findings suggest that some parents perceive "there is something wrong with the pregnancy" and anticipate the foetus loss. This could be influenced by either previous experiences or physical signs that make them suspect. The baby's death triggers an emotional outbreak characterized by shock, pain and sharpened by the feeling of loneliness.

Parents need to legitimize grief, giving identity to the dead baby, saying goodbye to him and participating in rituals according to their beliefs. When a child dies, whether a baby, a child, or an adult child, there may also be grandparents who also grieve. Grandparents experience the same feelings of grief as parents, albeit the loss is a different experience.

It is particularly difficult for grandparents to experience a grandchild's death when they feel their lives have been lived fully but the child's life was severed prematurely. Especially when an adult child has died, the grandparents' feelings of loss and grief are often not acknowledged. As a result, grandparents may not get the support they need. Too, some elderly adults do not easily share their feelings with others, even their own children. Parents may feel angry toward the health care team for not saving their child or for poor communication that left the parent confused and unsupported.

Parents of teens and adults who died under circumstances in which their friends' behavior and lifestyles contributed to the death may fuel anger toward the child or the child's friends. Although difficult to express when a child dies by suicide, parents may feel anger toward the child for not sharing their emotional state, for not seeking help, or for they themselves believing they should have seen signs. Some may feel anger towards friends who have children and the friends having the good fortune to be able to watch them grow older and reach particular milestones such as graduation or marriage.

Big countries like Brazil and China reduced their child mortality rates 10-fold over the last 4 decades. Other countries – especially in Africa – still have high child mortality rates, but it's not true that these countries are not making progress. In Sub-Saharan Africa, child mortality has been continuously falling for the last 50 years (1 in 4 children died in the early 60s – today it is less than 1 in 10). Over the last decade this improvement has been happening faster than ever before.

Rising prosperity, rising education and the spread of health care around the globe are the major drivers of this progress. Two hundred years ago the child mortality rate was extremely high around the world –more than 40% of all children died. Since then the child mortality rate has declined more than 10-fold.

Because we need to further reduce child deaths we are studying the causes of death of children today and how it was possible to improve child health so very substantially in the past in ourentry on child mortality. With the dramatic increase in the survival of low birth weight babies, the death of a very tiny, sick, or deformed newborn is no longer always expected. Parents' hopes may be buoyed with the suggestion of each additional medical procedures, and the added time that the child lives increases their attachment. The advent of new technologies and surgical procedures that might prolong survival but at a price of pain, discomfort, or survival with gross disfigurement or retardation presents new problems to both parent and physicians. This situation may engage them in complex legal and ethical issues that intensify the emotional difficulties parents have in dealing with their loss.

The majority of studies on this issue have focused on divorce as an indicator of stress upon the parents. However, there is a great deal of variability across studies regarding the divorce rates following a child's death. A recent review of these studies concluded that some writers give overly high estimates of divorce for which there is no empirical support . On the other hand a substantial minority of couples do seem to experience severe marital distress. Bohannon , for example, conducted a longitudinal study of couples' grief responses and marital functioning.

Died From Lack Of Attention About the same proportion had considered divorce after the death of their child. A major difficulty in doing such research is that the frequency of divorce in the U.S. population is about 50 percent. Separating the "real" contribution of the death of a child from other causes of marital strife in bereaved families is a difficult research challenge. New Jersey's review team, the second-oldest in the U.S., includes ob/gyns, nurses, mental health specialists, medical examiners, even a nutritionist. Every few years, the committee publishes a report, focusing on things like the race and age of the mothers who died, the causes of death, and other demographic and health data. In the past, the findings have been used to promote policies to reduce postpartum depression.

The requirement of a combination of factors including a specific underlying susceptibility, a specific time in development, and an environmental stressor has been proposed. These environmental stressors may include sleeping on the stomach or side, overheating, and exposure to tobacco smoke. Accidental suffocation from bed sharing (also known as co-sleeping) or soft objects may also play a role. Another risk factor is being born before 39 weeks of gestation. SIDS makes up about 80% of sudden and unexpected infant deaths . The other 20% of cases are often caused by infections, genetic disorders, and heart problems.

While child abuse in the form of intentional suffocation may be misdiagnosed as SIDS, this is believed to make up less than 5% of cases. It is not uncommon to feel anger toward others in society, especially friends and family members who do not acknowledge the child, or who discount parental grief responses and go on as if the child's death did not happen. Couples who experience a miscarriage may experience their grief all alone, as few people may have known of the pregnancy loss. What this also means is that the share of child deaths from older or younger children also depends on how much progress countries have made on vaccine coverage and other interventions.

There, neonatal deaths account for only 37% of under-5 deaths, whereas in most Asian, European and American countries this share is 50% or higher. This is because many countries across Sub-Saharan Africa still have significant progress to make in the prevention of vaccine-preventable diseases. Our concern will then turn towards countries where the chances of child mortality is high, and the number of births increasing.

Countries where children are most likely to die – Somalia, Chad, Central African Republic, Sierra Leone, Nigeria, and Mali – will all have an increasing number of children in the coming decades. Progress on reducing child deaths will here therefore become a race between declining child mortality rates and an increasing number of children. Of course, the death of every child is an enormous tragedy, and in many countries far too many children die because of causes we know how to prevent and treat. The deaths of infants, either through miscarriage, stillbirth, newborn death, or SIDS, were until recently regarded even by most professionals as "nonevents" or "non-deaths" affecting unnamed "non-persons" .

While there are common issues in bereavement for all infants, each of these circumstances of infant death brings its unique stresses related to the way in which it occurs as well as to the individual parent . The fourth Millennium Development Goal aims to reduce the 1990 mortality rate among under-five children by two thirds. Child mortality is also closely linked to MDG 5- to improve maternal health. Since more than one third of all child deaths occur within the first month of life, providing skilled care to mothers during pregnancy, as well as during and after birth, greatly contributes to child survival.
