How to modify style of android "force close" window?

Question

Does anybody know how to modify the style of the "force close" window (FC dialog)? I found a custom ROM with a nice picture at the dialog. At what place can I find the popup?

I would recommend you to avoid the force close dialog rather than styling it :) – Labiodental

Answer 1

Try to override uncaughtException,

@Override
public void uncaughtException(Thread thread, Throwable e) {
e.printStackTrace();    

   try {    

      // create your custom dialog
      displayErrorMessageToast();

      Thread.sleep(3500);    
   } catch (Exception e1) {    
      Log.e(TAG, "Error: ", e1);    
   } 
   finally 
   {    
      killApplicationProcess(e);    
   }
}

but this isn't posiable change all system fc dialog style in this way. I just need modify the fc dialog style. – Deina

if you llok at @Praful Bhatnagar 's answer, you can write your own UnCaughtException.java and set thread for your activity, like this : Thread.setDefaultUncaughtExceptionHandler(new UnCaughtException(youractivity.this)); – Burchell

thanks very much, that answer could only modify ONE app fc dialog style. but i wanna change all system app fc dialog style. – Deina

Try the approach given in this blog

Copying here for quick reference:

Android UncaughtExceptionHandler

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 application crashed.

Activity Code

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
import android.widget.ViewFlipper;
/**

*/
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");
}
}
