एंड्रॉइड: कैच त्रुटि "दुर्भाग्य से 'ऐप' ने काम करना बंद कर दिया है"

Question

क्या यह त्रुटि पकड़ना/संभालना संभव है और एक अलग संवाद संदेश प्रदर्शित करना संभव है? की तरह: क्षमा करें "" को काम करने बंद कर दिया है

Answer 1

हाँ, यह एंड्रॉयड फोर्स बंद Message.Do निम्नलिखित अनुकूलित करने के लिए

अपने स्वयं के अपवाद संचालक कक्षा बनाएं संभव है

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

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

     int y = 5/0; 
    } 

और यह वह वर्ग है जो फोर्स क्लोज डायलॉग को कैप्चर करता है और हमारे कस्टमडिअलॉग को दिखाता है।
