How to handle code when app is killed by swiping in android?

I just resolved a similar kind of issue.

Here is what you can do if its just about stopping service when application is killed by swiping from Recent app list.

Inside your Manifest file, keep flag stopWithTask as true for Service. Like:

<service
    android:name="com.myapp.MyService"
    android:stopWithTask="true" />

But as you say you want to unregister listeners and stop notification etc, I would suggest this approach:

  1. Inside your Manifest file, keep flag stopWithTask as false for Service. Like:

    <service
    android:name="com.myapp.MyService"
    android:stopWithTask="false" />

  2. Now in your MyService service, override method onTaskRemoved. (This will be fired only if stopWithTask is set to false).

    public void onTaskRemoved(Intent rootIntent) {

    //unregister listeners
    //do any other cleanup if required

    //stop service
    stopSelf();  
}

Refer my question for more details, which contains other part of code, too.

Hope this helps.


Create a Service like this

public class OnClearFromRecentService extends Service {

@Override
public IBinder onBind(Intent intent) {
    return null;
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Log.d("ClearFromRecentService", "Service Started");
    return START_NOT_STICKY;
}

@Override
public void onDestroy() {
    super.onDestroy();
    Log.d("ClearFromRecentService", "Service Destroyed");
}

@Override
public void onTaskRemoved(Intent rootIntent) {
    Log.e("ClearFromRecentService", "END");
    //Code here
    stopSelf();
}

}

2)register this service in manifest.xml

<service android:name="com.example.OnClearFromRecentService" android:stopWithTask="false" />

  1. Then start this service on your splash activity

    startService(new Intent(getBaseContext(), OnClearFromRecentService.class));

And now whenever you will clear your app from android recent Then this method onTaskRemoved() will execute.


I resolved similar issue. If you want after swiping from recent task and on next launch it to behave properly then follow below steps:-

1) Save process ID in shared preference:

SharedPreferencesUtils.getInstance().putInt(SharedPreferencesUtils.APP_PROCESS_ID, android.os.Process.myPid());

2) When application is launched from launcher after clear from recent task then do:

int previousProcessID = mSharedPreferencesUtils.getInt(SharedPreferencesUtils.APP_PROCESS_ID);

int currentProcessID = android.os.Process.myPid();

if ((previousProcessID == currentProcessID)) {
    // This ensures application not killed yet either by clearing recent or anyway
} else {
    // This ensures application killed either by clearing recent or by anyother means
}
