Problem registering for C2DM in Android

Question

I'm trying to test the C2DM framework. I got the confirmation email a couple of days ago and then tryied to create a client that could register. For that purpose, I created a simple client following the steps described in this tutorial: http://code.google.com/intl/es-419/android/c2dm/index.html.

The Android manifest file contains among other things this code:

<permission android:name="com.bilthon.ufrj.permission.C2D_MESSAGE" android:protectionLevel="signature" />
<uses-permission android:name="com.bilthon.ufrj.permission.C2D_MESSAGE" />

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

<uses-permission android:name="android.permission.INTERNET"/>

<receiver android:name=".C2DMReceiver" android:permission="com.google.android.c2dm.permission.SEND">

<intent-filter>
   <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
   <category android:name="com.bilthon.ufrj" />
</intent-filter>

<intent-filter>
   <action android:name="com.google.android.c2dm.intent.RECEIVE" />
   <category android:name="com.bilthon.ufrj" />
</intent-filter>
</receiver>

And then, the main activity launched when the program starts has the following code:

Intent registrationIntent = new Intent("com.google.android.c2dm.intent.REGISTER");
registrationIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0)); // boilerplate
registrationIntent.putExtra("sender","[email protected]");
Log.d("WelcomeScreen","[email protected]");
startService(registrationIntent);

I also registered a google account on the AVD running my client, as they said it was required. But the problem is that I cannot get the broadcast receiver to "wake up". I don't know what could be wrong. By analysing the logs, I can see that the registration intent is created and apparently used correctly, but the receiver code just never is executed, what could be wrong?

Thanks in advance Nelson

Well.. just sorted it out, the problem was with the declaration of the receiver. The tags for the receiver should go inside the application tag, just as demonstrated here: http://developer.android.com/guide/topics/manifest/manifest-intro.html

Here's an example of a well formated Manifest for a C2DM application. Thanks to Mark Murphy for posting the link at the android-c2dm group.

And sorry for the silly mistake.
