This plugin is for use with Cordova and in an Android project to enable push notifications via Google's GCM (Google Cloud Messaging) service. Previously, push notifications on Android used C2DM, but that has since been deprecated.

Important - this demo will not go through the complete registration process on an emulator (it will work on a real device). To get it to work on an emulator, you need to install the right libraries. You can follow this guide under the section titled "Installing helper libraries and setting up the Emulator"

Add the com.google.android.gcm and com.plugin.GCM packages to your project. Add the GCMIntentService.java file to your application's main package.

Modify your src.app_name.gcm.GCMIntentService.java "package" name on the first line to use you application name.

Modify your AndroidManifest.xml to include the following lines to your manifest tag, replacing your_app_package with your app's package path:

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

<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<permission android:name="your_app_package.permission.C2D_MESSAGE" android:protectionLevel="signature" />
<uses-permission android:name="your_app_package.permission.C2D_MESSAGE" />

Modify your AndroidManifest.xml to include the following lines to your application tag, replacing your_app_package with your app's package path:

<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_app_package" />
  </intent-filter>
</receiver>

<service android:name=".GCMIntentService" />

Modify your res/xml/config.xml to include the following line in order to tell Cordova to include this plugin and where it can be found:

<plugin name="GCMPlugin" value="com.plugin.GCM.GCMPlugin" />

Follow the instructions here on creating a Google API project to obtain a GCM sender ID. Replace all instances of "your_sender_id" in this plugin with that id (make sure you pass the ID as a string, not an int). Add your app to the [Google Play Store] and input your API keys in the "Services & APIs" section. No need to go live with the app to test it out.

Add the GCMPlugin.js script to your assets/www folder (or javascripts folder, wherever you want really) and include it in your main index.html file.

<script type="text/javascript" charset="utf-8" src="GCMPlugin.js"></script>

In the CORDOVA_GCM_script.js script you will see an example of how to interact with the GCMplugin. Modify it to suit your needs.

If you run this demo using the emulator you will not receive notifications from GCM. You need to run it on an actual device to receive messages or install the proper libraries on your emulator (You can follow this guide under the section titled "Installing helper libraries and setting up the Emulator")

If everything seems right and you are not receiving a registration id response back from Google, try uninstalling and reinstalling your app. That has worked for some devs out there.

Google gcm supports booth json and plain text messages but this plugin is setup for json use only

If you copy the AndroidManifest.xml settings from the readme page on github, you may run into issues with invalid whitespace. If so, remove all white spaces and manually re-add them or copy the manifest settings directly from the file (not the web).
