Actions restart when the application exits the nonexistent handler

Question

Actions restart when the application exits the nonexistent handler

In my application, I use a global exception handler to avoid forced closure. But the action is launched after calling system.exit (0) .... ????

I also bound an exception handler.

A slightly belated answer, but ... In my case, this happens only on a few devices, for example, Samsung Nexus 7. To avoid this annoying restart, I remember the current activity in a static variable and call finish() before System.exit :

 // base class for all activities in my application class BaseActivity extends Activity { private static BaseActivity sCurrentActivity = null; @Override protected void onCreate( Bundle savedInstanceState ) { super.onCreate( savedInstanceState ); sCurrentActivity = this; } @Override protected void onStart() { super.onStart(); sCurrentActivity = this; } @Override protected void onResume() { super.onResume(); sCurrentActivity = this; } @Override protected void onPause() { super.onPause(); sCurrentActivity = null; } public static System_exit( int exitCode ) { if ( null != sCurrentActivity ) { sCurrentActivity.finish(); sCurrentActivity = null; } System.exit( exitCode ); } }

Thanks! It worked - BUT: you have to complete your main activity, it will not work if you finish something else. And here are a few improvements: if you ever need a static link to activity, it is better to use a weak link and a static getter instead of a strong link:

 public class MainActivity extends Activity { private static WeakReference<MainActivity> sharedActivity = null; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); sharedActivity = new WeakReference<MainActivity>(this); setContentView(R.layout.activity_main); } public static MainActivity sharedActivity() { try { return sharedActivity.get(); } catch (Exception e) { return null; } } }

The WeakReference will not interfere with garbage collection from GC'ing activity. If it was built, the return value of WeakReference will be null, otherwise the activity object will be returned. This makes your code easier and prevents access to finished activities.
