Question

I’m having some trouble implementing C2DM registration. My BroadcastReceiver is never called.

I’m working with the emulator (Google APIs (Google Inc.) – API Level 8) with my gmail account set up. It seems to work because the BroadcastReceiver of the Thomas Malmsten exemple is working fine on my emulator (link).

Here is my manifest :

<permission android:name="my.package.permission.C2D_MESSAGE" android:protectionLevel="signature"></permission>
<uses-permission android:name="my.package.permission.C2D_MESSAGE" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.USE_CREDENTIALS" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
<uses-sdk android:minSdkVersion="8" />

<application android:name=".utils.MyApp" ...>

   <receiver android:name=".C2DMBroadCastReceiver" android:permission="com.google.android.c2dm.permission.SEND">
      <!-- Receive the actual message -->
      <intent-filter>
          <action android:name="com.google.android.c2dm.intent.RECEIVE" />
          <category android:name="my.package" />
      </intent-filter>
      <!-- Receive the registration id -->
      <intent-filter>
          <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
          <catemgory android:name="my.package" />
      </intent-filter>
  </receiver>

    <activity android:name=".views.LoginScreen" android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <!-- lots of activities -->
    <!-- lots of services -->

</application>

For now, I just want to write something in the logcat.

My Broadcast Receiver
package my.package;

import ...;

public class C2DMBroadCastReceiver extends BroadcastReceiver {

    @Override
    public final void onReceive(Context context, Intent intent) {
        Log.d("C2DMBroadCastReceiver ", "Received something from Google.");
        if (intent.getAction().equals("com.google.android.c2dm.intent.REGISTRATION")) {
            Log.d("C2DMBroadCastReceiver ", "Received a registration ID from Google.");
        } else if (intent.getAction().equals("com.google.android.c2dm.intent.RECEIVE")) {
            Log.d("C2DMBroadCastReceiver ", "Received a C2DM message from Google.");
        }
    }
}

Here is my registration fonction :

Context context = MyApp.getAppContext();
            Intent registrationIntent = new Intent("com.google.android.c2dm.intent.REGISTER");
            registrationIntent.putExtra("app", PendingIntent.getBroadcast(context, 0, new Intent(), 0)); 
            registrationIntent.putExtra("sender", "[e-mail]");
            Log.w("Register", "Intent to register");
            context.startService(registrationIntent);

Finaly, the logcat :

Sorry about all the code, but i really don’t know what’s going on!

Thank you,
Matthieu

ps : It’s not working either with a Nexus One.

Really stupid mistake : catemgory instead of category in the manifest.
