GCM API KEY

By following Cloud messaging, you can get google-services.json file and place it in android/app directory

Usage

var GcmAndroid = require('react-native-gcm-android');
GcmAndroid.addEventListener('register', function(token){
  console.log('send gcm token to server', token);
});
GcmAndroid.addEventListener('notification', function(notification){
  console.log('receive gcm notification', notification);
});
GcmAndroid.requestPermissions();

• By default, if the activity is not running, it will show a notification on phone. Otherwise, you can get notification in GcmAndroid.addEventListener('notification' listenter.

• You should send GCM notification that has "data" key with following infos

{
  "largeIcon": "ic_launcher",
  "contentTitle": "Awesome app",
  "message": "Hi, how are you?",
  "ticker": "hi...",
}

• You can remove <service android:name="com.oney.gcm.RNGcmListenerService"/> and change to your custom GcmListenerService in AndroidManifest.xml to handle notifications in java codes
