Android - Customised New Incoming Call Screen

Question

I\'m trying to make an new incoming call screen in android,

when i get an incoming call my app starts - but crashes immediately, and the default incoming call scree

Answer 1

Ok, in order to make my new page in the front i need to make it sleep for a while... so the new code will be:

public class MyPhoneBroadcastReceiver extends BroadcastReceiver{

    public void onReceive(final Context context, Intent intent) {


        Thread pageTimer = new Thread(){
            public void run(){
                try{
                    sleep(1000);
                } catch (InterruptedException e){
                    e.printStackTrace();
                } finally {
                    Intent i = new Intent();
                    i.setClass(context, Call.class);
                    i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    context.startActivity(i);
                }
            }
        };
        pageTimer.start();
    }
}

But - the original incoming call program is still running in the background...

Is there any way to replace it instead opening new app ontop of it?

Thanks!
