Android: Catch Error "Leider funktioniert die App nicht mehr"

Question

ist es möglich, diesen Fehler zu erfassen/zu behandeln und eine andere Dialogmeldung anzuzeigen? wie: Sorry "AppName" gestoppt

Answer 1

Arbeits Ja ist es möglich, die Android Force Close Message.Do die folgenden,

Ihre eigene Exception-Handler-Klasse erstellen

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     Thread.setDefaultUncaughtExceptionHandler(new UnCaughtException(MainActivity.this)); 

     int y = 5/0; 
    } 

Und diese anpassen ist die Klasse, die den Force-Close-Dialog erfasst und unseren CustomDialog anzeigt.
