gcm getMessageType(intent) always return null

I can only get null for the messageType when I called the function gcm.getMessageType(intent) in the class which I extended the IntentService. I'm sure the intent parameter is the intent I received in your BroadcastReceiver.
In the page GCM returns a null message type they said the problem is more or less related to the manifest file, but I checked my file and could not find the reason. The example I use is from http://www.grokkingandroid.com/?s=gcm&x=0&y=0.
My AndroidManifest.xml is provided as below. Much appreciated if someone can help me to figure it out. I am stuck in this problem for several days.

Check my repo: https://github.com/datomnurdin/worklight-mobile
Thanks a lot in advance.

Move this block:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="com.rmbp.rmbp.NOTIFICATION" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
to the activity which you want to start first. Intent filter will mark this activity as default for start from launcher.
For example:
<activity
android:name="com.rmbp.SplashScreen"
android:configChanges="orientation|keyboardHidden|screenSize"
android:label="#string/title_activity_splash_screen"
android:launchMode="singleTask"
android:screenOrientation="portrait" >
</activity>
<activity
android:name="com.rmbp.rmbp"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="com.rmbp.rmbp.NOTIFICATION" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>

Android Manifest no launcher found

Im working on android map API and I got it working. The problem is when add a new activity (.ListActivity) and make it my Launcher the console is giving me an error "No Launcher found". Here is my code...
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

android:label="#string/title_activity_list" >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</activity>
</application>

It has to be in an intent-filter together with the MAIN.
<activity
android:name="com.example.themap.ListActivity"
android:label="#string/title_activity_list" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

In your second activity addition you forgot to add intent-filter tags. that is why you are getting the error.
Change your xml file second activity addition as below.
<activity
android:name="com.example.themap.ListActivity"
android:label="#string/title_activity_list" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

tag is missing in com.example.themap.ListActivity
Also you have more than one android.intent.action.MAIN defined
This is defined in both your activities

Here Is my manifest file :

What I can see wrong is
enabled="false"
needs to be
android:enabled="false"
In addition, you need to add
</manifest>
at the end of your manifest.
