Question

I’m using GCM on my application, but when I try to register my device the onRegistered method on GCMIntentService isn’t called.

I installed the GCM demo application on my device and it works:

http://developer.android.com/guide/google/gcm/demo.html

In this app the device is registered and I can send messages to it. I tried to use GCM in my own app using the same GCMIntentService. I adapted the manifest too, but when I try to register this is what appears in my log:

09-25 10:00:10.195: V/GCMRegistrar(591): Registering app com.pfc.dps of senders 38322290XXXXX

And nothing else, I get no response. These are my manifest permissions:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.pfc.dps"
    android:versionCode="1"
    android:versionName="1.0" >

<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="16"/>

<uses-permission android:name="android.permission.MANAGE_ACCOUNTS"></uses-permission>
<uses-permission android:name="android.permission.GET_ACCOUNTS"></uses-permission>
<uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS"></uses-permission>
<uses-permission android:name="android.permission.USE_CREDENTIALS"></uses-permission>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.READ_SYNC_STATS" />
<uses-permission android:name="android.permission.READ_SYNC_SETTINGS" />
<uses-permission android:name="android.permission.WRITE_SYNC_SETTINGS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.GET_TASKS"/>

<!-- Keeps the processor from sleeping when a message is received. -->
<uses-permission android:name="android.permission.WAKE_LOCK" />
<!-- Creates a custom permission so only this app can receive its messages. -->
<permission
    android:name="com.pfc.dps.permission.C2D_MESSAGE"
    android:protectionLevel="signature" />
<uses-permission
    android:name="com.pfc.dps.permission.C2D_MESSAGE" />

<!-- This app has permission to register and receive data message. -->
<uses-permission
    android:name="com.google.android.c2dm.permission.RECEIVE" />

I created a new project in Google APIs console to check if it worked that way, but I get the same result using any of the Sender IDs.

Does anybody know why is that?

Thank you!

After the “Registering app *your_package* of senders *sender_id*“

You should receive a onReceive event which will call your GCMIntentService to wake your app up.

If you do not have that, please check you have missed the receiver or forgotten to change the category for your own package.

<receiver android:name="com.google.android.gcm.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="***your_package***" />
     </intent-filter>
</receiver>
