Android - Sending message to a handler on a dead thread, Toast error

Question

I am using C2DM services and when I get message, I get also error of "Sending message to a handler on a dead thread" while displaying Toast message, where I want to see message, which arrived. Using code:

@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 class which extends C2DMBaseReceiver. Toast messatge never displays.

What is the error in here? Is there any soultion?

There is a workaround. However I can't get it to work with that workaround.

I solved a similar problem by creating a Handler in the C2DMBaseReceiver constructor and added a Runnable that shows the Toast.

Something 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 the subclass.

Hope it works!
