GCM messages are not received unless SEND permission is removed

In order to implement GCM correctly, a com.google.android.c2dm.SEND permission should be specified for the receiver as per the official docs:

The receiver should require the com.google.android.c2dm.SEND permission, so that only the GCM Framework can send a message to it.

When I add that permission however, I get this error when a message is received.

W/GTalkService(25224): [DataMsgMgr] broadcast intent callback: result=CANCELLED forIntent { act=com.google.android.c2dm.intent.RECEIVE cat=[com.XXX.XXX] (has extras) }

followed by this error:

W/ActivityManager(283): Permission Denial: broadcasting Intent { act=com.google.android.c2dm.intent.RECEIVE cat=[com.XXX.XXX] flg=0x10 (has extras) } from com.google.android.syncadapters.contacts requires com.google.android.c2dm.SEND due to receiver com.XXX.XXX/com.XXX.XXX.GcmBroadcastReceiver

If I remove that permission only, without changing anything else, the receiver works normally and I can process the message.

and here's the receiver definition in AndroidManifest.xml

<receiver
        android:name="com.XXX.XXXX.GcmBroadcastReceiver"
        android:permission="com.google.android.c2dm.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />

            <category android:name="com.XXX.XXX" />
        </intent-filter>
    </receiver>

I'm using the debug certificate during testing, in case that might be relevant.

Try com.google.android.c2dm.permission.SEND instead of com.google.android.c2dm.SEND, such as:

<receiver
  android:name="GCMBroadcastReceiverCompat"
  android:permission="com.google.android.c2dm.permission.SEND">
  <intent-filter>
    <action android:name="com.google.android.c2dm.intent.RECEIVE"/>
    <category android:name="com.commonsware.android.gcm.client"/>
  </intent-filter>
</receiver>

(from this sample app)

try this:

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

<receiver
        android:name="com.robustastudio.mateegy.GcmBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>

            <action android:name="com.google.android.c2dm.intent.RECEIVE" />

            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

            <category android:name="com.robustastudio.mateegy" />
        </intent-filter>
    </receiver>
