GCM(Google Cloud messaging) don’t work in china. But WHY ?
GCM is a derived from Google it should work in android devices irrespective of country.
The reason is from this source
GCM requires devices running Android 2.2 or higher that also have the Google Play Store application installed
Google Cloud Messaging (GCM) works with the Google Play Services SDK and as you probably know Google Play is not available in China (just like most of other Google services). ~Source2
Here is a list of some alternative for the GCM:

This post will deal with implentation of https://pushy.me/ (Military-grade reliability and speed for push notifications)
Yes as the description say pushy service is reliable, speedy no doubt and also easy to implement
Check pricing (its not expensive however there are other free push service available like JPush) and documentation .
Here is the procedure from document to implement Pushy notification
Get The SDK
Download the link of the latest sdk.
https://pushy.me/downloads/sdk/pushy-1.0.9.zip
Extracting the SDK
Extract the archive and copy the pushy-x.x.x.jar and pushy-jackson.jar files to your libs/ folder.
Import the SDK
Add this compilation statement in module level build.gradle file
|
1 2 3 |
dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) } |
Register a Device
-
Synchronous call
1String registrationID = Pushy.register(getApplicationContext()); -
Asynchronous Example
123456789101112131415161718192021222324252627282930313233new RegisterForPushNotificationsAsync().execute();private class RegisterForPushNotificationsAsync extends AsyncTask<Void, Void, Exception> {protected Exception doInBackground(Void... params) {try {// Ask Pushy to assign a unique registration ID to this deviceString registrationID = Pushy.register(getApplicationContext());// Send the registration ID to your backend server via an HTTP GET requestnew URL("https://{YOUR_API_HOSTNAME}/register/device?registration_id=" + registrationID).openConnection();}catch (Exception exc) {// Return exc to onPostExecutereturn exc;}// Successreturn null;}@Overrideprotected void onPostExecute(Exception exc) {// Failed?if (exc != null) {// Show error as toast messageToast.makeText(getApplicationContext(), exc.toString(), Toast.LENGTH_LONG).show();return;}// Succeeded, do something to alert the user}}
Final Step
Add this initialization statement in the laucher activity
|
1 |
Pushy.listen(this); |
Set up manifest : Permissions, recievers and services
|
1 2 3 4 5 6 7 8 9 |
<!-- Pushy Permissions --> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <!-- End Pushy Permissions -- |

Backend Configuration
For backend configuration visit https://dashboard.pushy.me/apps
Signup a account and create a application. You will be provided a secret key for each app.
Send Notification from Server
Here is a test script that send a notification on a particular RegisterId that was obtain in Register a device step
