GCM Push Notification Not Revived

Below you can find the manifest file, is their anything wrong with configuration of GCM push notification classes ?

no notification is received at all on android devices but apple devices receive the notification

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

<permission
    android:name="ac.iec.permission.C2D_MESSAGE"
    android:protectionLevel="signature"/>

<uses-permission android:name="ac.iec.permission.C2D_MESSAGE"/>
    <receiver
        android:name="com.google.android.gms.gcm.GcmReceiver"
        android:exported="true"
        android:permission="com.google.android.c2dm.permission.SEND">
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE"/>
            <category android:name="ac.iec"/>
        </intent-filter>
    </receiver>
           <service
        android:name=".pushnotification.GCMIntentService"
        android:exported="false">
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE"/>
        </intent-filter>
    </service>
    <service
        android:name=".pushnotification.MyInstanceIDListenerService"
        android:exported="false">
        <intent-filter>
            <action android:name="com.google.android.gms.iid.InstanceID"/>
        </intent-filter>
    </service>

You have miss some user permisssion & reciver set like this way.

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

this permission to set

<permission
    android:name="your package name.permission.C2D_MESSAGE"
    android:protectionLevel="signature" />

this user permission

<uses-permission android:name="your package.permission.C2D_MESSAGE" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name="android.permission.VIBRATE" />

this code set in application side.

 <!-- GCM Receiver -->
   <!-- this package name set your broadcast receiver class -->
    <receiver

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

            <!-- Receives the actual messages. -->
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <!-- Receives the registration id. -->
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

            <category android:name="main package name" />
        </intent-filter>
    </receiver>

try this code in your manifest file. Thanks.

<receiver> tag and <services> tag should be in <application> tag.

Or if you support pre-4.4, REGISTRATION action should be added. https://developers.google.com/cloud-messaging/android/client
