Android Push notification in china

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

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

dependencies {

compile fileTree(dir: 'libs', include: ['*.jar'])

}

Register a Device

Synchronous call

String registrationID = Pushy.register(getApplicationContext());

1

String registrationID = Pushy.register(getApplicationContext());

Asynchronous Example

new 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 device
			String registrationID = Pushy.register(getApplicationContext());

			// Send the registration ID to your backend server via an HTTP GET request
			new URL("https://{YOUR_API_HOSTNAME}/register/device?registration_id=" + registrationID).openConnection();
		}
		catch (Exception exc) {
			// Return exc to onPostExecute
			return exc;
		}

		// Success
		return null;
	}

	@Override
	protected void onPostExecute(Exception exc) {
		// Failed?
		if (exc != null) {
			// Show error as toast message
			Toast.makeText(getApplicationContext(), exc.toString(), Toast.LENGTH_LONG).show();
			return;
		}

		// Succeeded, do something to alert the user
	}
}

new 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 device

String registrationID = Pushy.register(getApplicationContext());

// Send the registration ID to your backend server via an HTTP GET request

new URL("https://{YOUR_API_HOSTNAME}/register/device?registration_id=" + registrationID).openConnection();

}

catch (Exception exc) {

// Return exc to onPostExecute

return exc;

}

// Success

return null;

}

@Override

protected void onPostExecute(Exception exc) {

// Failed?

if (exc != null) {

// Show error as toast message

Toast.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

Pushy.listen(this);

1	Pushy.listen(this);

Set up manifest : Permissions, recievers and services

<!-- 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 --

<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 --

<!-- Pushy Declarations -->

<!-- Pushy Notification Receiver -->
<!-- Incoming push notifications will invoke the following BroadcastReceiver -->
<receiver android:name=".PushReceiver" android:exported="false">
    <intent-filter>
        <!-- Do not modify this -->
        <action android:name="pushy.me" />
    </intent-filter>
</receiver>

<!-- Pushy Update Receiver -->
<!-- Do not modify - internal BroadcastReceiver that restarts the listener service -->
<receiver android:name="me.pushy.sdk.receivers.PushyUpdateReceiver" android:exported="false">
    <intent-filter>
        <action android:name="android.intent.action.PACKAGE_REPLACED" />
        <data android:scheme="package" />
    </intent-filter>
</receiver>

<!-- Pushy Boot Receiver -->
<!-- Do not modify - internal BroadcastReceiver that restarts the listener service -->
<receiver android:name="me.pushy.sdk.receivers.PushyBootReceiver" android:exported="false">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED"/>
    </intent-filter>
</receiver>

<!-- Pushy Socket Service -->
<!-- Do not modify - internal socket service -->
<service android:name="me.pushy.sdk.services.PushySocketService"/>

<!-- End Pushy Declarations -->

<intent-filter>

</intent-filter>

</receiver>

<intent-filter>

</intent-filter>

</receiver>

<intent-filter>

</intent-filter>

</receiver>

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

// Require Pushy API Class
require('pushy.php');

// Payload data you want to send to devices
$data = array('message' => 'PUSH MESSAGE !!!!!');

// The recipient device registration IDs
$ids = array('XXXXXXXXXXXXXXXXXXXXXXXXX');

// Send it with Pushy
PushyAPI::sendPushNotification($data, $ids);
