Because user would gain trust to your app and its resume supported capability with confidence that no matter how much times user presses Home, your app will remain intact and bold. If this is implemented and handled by developers carefully, this could be the very useful functionality from the user’s perspective. That command kills the whole process of your app like the Terminate App button while adb shell am kill only kills processes that are safe to kill to reallocate resources such as memory, CPU etc. Please note that this is different than the command adb shell kill. If its in focus and foreground state, nothing would happen. It must be noted that your app should be in background while running this command. And open the terminal there and type this command. Simply go to the your Android SDK directory, and look for the platform-tools directory. And when you come back to the app from Recent Apps screen, the app will restart from the main launcher screen instead of the screen where user left it. Pressing this button will completely kill your application process. Usually, this helps in other cases but unfortunately not in this case. Because this is a very common thing users do on Android phones.īut, how can you simulate this? How can you kill some app like Android OS does manually?Īndroid Studio comes with a simple button “Terminate Application” in the *Logcat *panel which kills your running debug app on emulator/device. You need to be able to simulate this scenario and test how your app behaves. Firebase gets these crazy crashes with different logs each time because you never know at what screen user pressed home for some other app. Your current Activity is using static data and expects it as a non-null data. Now, user comes back to your app by opening it from the Recent Apps option, and boom □. So, Android OS simply goes ahead and kills your app to reclaim that precious memory. It sees that your app is in background for a while (say more than 30 minutes or so) and you have this big data stored as static variable in the memory. Suddenly Android OS needs some memory and it looks in the inactive apps of the system. Sometimes users press Home button to switch from your app to some other task they intend to do. The answer lies in a simple word: Process Lifecycle.
