Android Send Application Crash Report to Developer

Android-Send application crash report to developer

Implemented by objects that want to handle cases where a thread is being terminated by an uncaught exception. Upon such termination, the handler is notified of the terminating thread and causal exception. If there is no explicit handler set then the thread's group is the default handler. 

Below I wrote the code user can send some bug report to Developer when the application crashed.

Activity Code


-->
import android.app.Activity;

import android.os.Bundle;

import android.widget.TextView;

import android.widget.ViewFlipper;

/**

*

* @author vijayakumar

*

*/

public class AndroidMADQAActivity extends Activity {

ViewFlipper flipper;

TextView textView = null;

Throwable throwable;

UnCaughtException un = null;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

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

Integer[] items = { R.drawable.a, R.drawable.e,R.drawable.d,R.drawable.c};

setContentView(R.layout.main);

textView.setText("Helloo Error Welcome");


}

}
