Android - sending message to dead thread handler, Toast error

Question

I use C2DM services, and when I receive the message, I also get the error message "Sending a message to the processor in a dead thread" when a Toast message is displayed, where I want to see the message that arrived. Code Usage:

@Override protected void onMessage(Context context, Intent intent) { Log.e("C2DM", "Message: arived"); Bundle extras = intent.getExtras(); if (extras != null) { //Toast.makeText(this.getApplicationContext(), (CharSequence) extras.get("payload"), Toast.LENGTH_LONG).show(); } } 

onMessage method is used in a class that extends C2DMBaseReceiver . Toast messatge is never displayed.

What is the mistake here? Is there any soul?

Edit:

Answer 1

There is a workaround. However, I cannot get it to work with this workaround.

I solved a similar problem by creating a handler in the C2DMBaseReceiver constructor and adding Runnable, which shows Toast.

More or less like this:

 public void showToast(String message, Context context){ handler.post(new DisplayToast(message, context)); } private class DisplayToast implements Runnable{ String mText; Context mContext; public DisplayToast(String text, Context context){ mText = text; mContext = context; } public void run(){ Toast.makeText(mContext, mText, Toast.LENGTH_LONG).show(); } } 

And then you can just call the DisplayToast method from a subclass.

Hope it works!

See http://code.google.com/p/android/issues/detail?id=20915 for a possible root cause of the problem. It includes a workaround to solve the problem.
