Question

I try to register to C2DM but it doesn’t work. I included com.google.android.c2dm in my project. When I try to find com.google.android.c2dm.intent.REGISTER , it doesn’t find anything :

String action = "com.google.android.c2dm.intent.REGISTER";
final PackageManager packageManager = context.getPackageManager();
final Intent intent = new Intent(action);
List<ResolveInfo> list = packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);

list.size() give 0. Any idea?

EDIT : mu manifest file contains the corrects permissions :

<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />

Answer 1

You need to make sure you have the com.google.android.c2dm.permission.RECEIVE permission in your manifest file.

Also, I implemented registration using the following boilerplate

Intent registrationIntent = new Intent("com.google.android.c2dm.intent.REGISTER");
registrationIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0)); 
registrationIntent.putExtra("sender", emailOfSender);
startService(registrationIntent);

You can refer to the full docs for basic setup.
