Question

I am using the Emulator of version 8. and when i am trying to register the Android Application then it will gives the null registration ID. Please help me to resolve this issue. How can i register the Android Application with C2DM.My code is to register the App.

Intent registrationIntent = new Intent("com.google.android.c2dm.intent.REGISTER");
registrationIntent.putExtra("app", PendingIntent.getBroadcast(startCode.this, 0, new Intent(), 0)); // boilerplate
registrationIntent.putExtra("sender", "[e-mail]");
startService(registrationIntent); 
handleRegistration(getApplicationContext(), registrationIntent);


private void handleRegistration(Context context, Intent intent) {
        String registration = intent.getStringExtra("registration_id"); 
        if (intent.getStringExtra("error") != null) {
            // Registration failed, should try again later.
            Log.e("ERROR", "ERROR");
        } else if (intent.getStringExtra("unregistered") != null) {
            // unregistration done, new messages from the authorized sender will be rejected
            Log.e("unregistered", "unregistered");
        } else if (registration != null) {
           // Send the registration ID to the 3rd party site that is sending the messages.
           // This should be done in a separate thread.
           // When done, remember that all registration is done. 
            Log.e("registration", registration);
        }
    }

Based on my experience, you need to add a google account in your emulator.

You can only do so with target of Google APIs 8, not Android 2.2.
