If you are using product flavors maybe you have the same problem than I found.
I found that when using flavors with diferent applicationId, then your package in the AndroidManifest file for the permission and the category is not correct. And this does not matter for Android 5.x, but for Android 2.3 causes that the broadcast receiver will never be called.
The solution I found is use the gradle's placeholder support. Using ${applicationId} the issue is resolved for all the Android versions.
build.gradle:
productFlavors {
prod {
applicationId 'com.democlientapp'
}
dev {
applicationId 'com.democlientapp.dev'
}
}
AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.democlientapp"
android:versionCode="1"

Use Latest dependency/library for GCM for sdk version 4 or heigher
compile "com.google.android.gms:play-services-gcm:10.2.0"
in build.gradle file in dependency. and add build.gragle level file
classpath 'com.google.gms:google-services:3.0.0'
its works for hiegher versions.
