In meiner Anwendung verwende ich einen globalen Exception-Handler, um ein erzwungenes Schließen zu vermeiden, aber eine Aktivität wird nach dem Aufruf von system.exit(0)....???? gestartet.

das angezeigte Logcat ist:

07-18 12:41:12.569: WARN/Resources(8453): Converting to string: TypedValue{t=0x12/d=0x0 a=2 r=0x7f07000a}

Ich habe den Exception-Handler auch angehängt: ....

package com.fss;

import java.lang.Thread.UncaughtExceptionHandler;

    public TopExceptionHandler(Context context) {

StaticStore.defaultHandler = Thread
.getDefaultUncaughtExceptionHandler();
this.context=context;

    }

      public void uncaughtException(Thread t,final Throwable e)

    {
         StaticStore.mfs=true;
        try{
         new Thread() {
            @Override
            public void run() {
                Looper.prepare();  

            Toast.makeText(context, "TOAST", Toast.LENGTH_LONG).show();

//              context.startActivity(intent);
            //

            //System.exit(0);//If you want to restart activity and want to kill after crash.s
                Looper.loop();

            }
        }.start();

        System.out.println("***************************EXception Ctached here********************");

        StackTraceElement[] arr = e.getStackTrace();

        String report = e.toString()+"\n\n";

        report += "--------- Stack trace ---------\n\n";

        for (int i=0; i<arr.length; i++)

        {

        report += "    "+arr[i].toString()+"\n";

        }

        report += "-------------------------------\n\n";

        // If the exception was thrown in a background thread inside

        // AsyncTask, then the actual exception can be found with getCause

        report += "--------- Cause ---------\n\n";

        Throwable cause = e.getCause();

        if(cause != null) {

        report += cause.toString() + "\n\n";

        arr = cause.getStackTrace();

        for (int i=0; i<arr.length; i++)

        {

        report += "    "+arr[i].toString()+"\n";

        }

        }

        Log.e("Report ::",report);

    }

        catch (Exception ex) {
              ex.printStackTrace();
          } finally {
              StaticStore.index=0;
              System.out.println("*************finally block enetered");
              StaticStore.dialog.dismiss();

Etwas verspätete Antwort, aber... Bei mir tritt das nur auf wenigen Geräten auf, zum Beispiel auf dem Samsung Nexus 7. Um diese lästigen Neustarts zu vermeiden, speichere ich die aktuelle Aktivität in einer statischen Variable und rufe finish() vor 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 );
  }
}

Danke! Das hat funktioniert - ABER: Sie müssen Ihre Hauptaktivität beenden, es funktioniert nicht, wenn Sie eine andere beenden. Und hier ist noch eine Verbesserung: Wenn Sie einen statischen Verweis auf eine Aktivität haben wollen, verwenden Sie besser einen schwachen Verweis und einen statischen Getter, anstatt eines starken Verweises:

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;
        }
    }
}

Die WeakReference wird den Garbage Collector nicht daran hindern, die Aktivität zu GC'ing. Wenn sie gesammelt wurde, ist der Rückgabewert der WeakReference null, ansonsten wird das Activity-Objekt zurückgegeben. Dies erleichtert Ihren Code und verhindert, dass Sie auf eine abgeschlossene Aktivität zugreifen.
