Question

In my Activity when the user says they want to enable notifications I call the following method:

private Intent buildRegistrationIntent(boolean register) {
    String intentName = "com.google.android.c2dm.intent." + (register ? "REGISTER" : "UNREGISTER");
    Intent intent = new Intent(intentName);
    intent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0)); // boilerplate
    intent.putExtra("sender", "[e-mail]");
    intent.putExtra("TEST", "test extras");

    return intent;
}

In my C2DM BroadcastReceiver I have this:

@Override
public void onReceive(Context context, Intent intent) {

    log.fine(Boolean.toString(intent.getExtras().containsKey("TEST")));
    log.fine(Boolean.toString(intent.getExtras().containsKey("registration_id")));

    if (intent.getAction().equals("com.google.android.c2dm.intent.REGISTRATION")) {
        handleRegistration(context, intent);
    } else if (intent.getAction().equals("com.google.android.c2dm.intent.RECEIVE")) {
        handleMessage(context, intent);
    }
}

The problem is, the “TEST” extra never gets sent to the C2DM BroadcastReceiver. The output from the below lines is “False” then “True” i.e. it has the registration_id, but not TEST.

Is there any way to pass some user defined data to the BroadcastReceiver or does the C2DM infrastructure eat the original intent and create a new one with just the registration_id?

Answer 1

It looks like this is impossible. Whatever receives the REGISTER intent doesn’t pass it on to onReceive.
