Question

I’m trying to set up an application to work with gcm but every time I get the phone_registration_error error
according to the Gcm documentation this error means:

Incorrect phone registration with Google. 
This phone doesn't currently support GCM.

But I don’t understand why my it’s not supported, I tested this on a real android device and a emulator with the google api’s

My MainActivity:

    @Override
public void onCreate(Bundle savedInstanceState) {
    checkNotNull(SENDER_ID, "SENDER_ID");

    GCMRegistrar.checkDevice(this);
    GCMRegistrar.checkManifest(this);

    final String regId = GCMRegistrar.getRegistrationId(this);
    Log.i(TAG,  "registration id =====  "+regId);
    if(regId.equals("")){
        GCMRegistrar.register(this, SENDER_ID);

    } else {
        Log.v(TAG, "Already Registred");
    }

    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

}

And my manifest:

Manifest on pastebin

GCM only works on devices that run android 2.2 or newer. Also GCM only works if a google account is installed for the device. This is also the reason google recommend using <uses-permission android:name="android.permission.GET_ACCOUNTS" /> in the manifest so you are sure the device has a google account.
