When the user resizes the Application screen size i.e. OnPause(), onStop() and onDestroy() callbacks are sequentially called. The app status is changed to "Destroyed". This scenario occurs when the user presses the close button of application window in his application. OnRestart(), onStart() and onResume() callbacks are sequentially called. Application launched from taskbar or other application not covering full screen.Īpplication going back to original-size window from taskbar or when App1 which is in full size, moves to its previous size or is not covering the full screen. OnPause() and onStop() callbacks are sequentially called for App2.Ģ.2. The application status is changed to "Stopped". When user presses minimize button of window or when one application gets covered by maximized window of another application. Application is on taskbar or hidden by another full screen application. You can assume that you are writing something in your favourite editor say App1 and you suddenly decided to maximize the window to full size covering the other Application say App2, then App2 will be fully covered by maximized window of App1.Īs for the life cycle is concerned: 2.1. In this scenario, only one application is visible to user in full window. This scenario occurs when the user presses maximize button of window in their application. When one application gets covered by maximized window of another application. Application goes to the taskbar and is not visible to the user. This scenario comes when user presses minimize button of window in their application. Application not visible to the user Case 1: The application status is changed back to "Running".Ģ. The application status is changed to "Paused". When you switch from App1 to App2 like scrolling some web pages in App2, App1 will go to the background and App2 will come to the foreground.Īs for the life cycle is concerned: 1.1. So in this case your App1 is in the foreground and App2 is in the background. You can assume that you are writing something in your favourite editor say App1. In this scenario both the applications are visible to user. Application going in background and foreground Initially you can assume that both the applications App1 and App2 are already launched and they are side by side on the screen. So, this blog will tell you how android life cycle methods are executed in Samsung DeX mode for all these scenarios.įor better understanding about android life cycle in Samsung DeX, I will be taking the example of two applications say App1 and App2 to describe about each scenario. As soon as the developer listens about all these features he would be little worried about how the android life cycle methods are invoked in all these scenario and how we will be writing code for better utilization of these features in an optimal way. Now your application will have features to minimize, maximize, close and resize the width and height of your activity according to your needs. interacting with mouse, keyboard and launching multiple applications on the same screen and switching between multiple applications with ease. Public class MainActivity extends AppCompatActivity void onCreate(Bundle savedInstanceState) XML File( res/layout/activity_main.Samsung DeX allows the user to run their Android application in a desktop like environment i.e. MainActivity.java package codedost.activitylifecycle Run the application to launch Android emulator or you can run it on your mobile also(which is way faster).Copy the content of res/layout/activity_main.xml file.Open an Empty Activity and name it as MainActivity.Open Android Studio and create a new Android application and name it as “ActivityLifeCycle” and company domain as codedost so your package will be automatically set.You can leave the XML file as it is or just copy it from below. Here I will be displaying messages with help of Toast and I have also provided with log messages so you can check it on the Android Monitor. Below is the source code demonstrating Activity Lifecycle.
