For Android push notification with GCM 2016 :
1) in Android SDK-> SDK Tools check Google Play services
2) in gradle add in dependencies just one line :
compile 'com.google.android.gms:play-services-gcm:9.4.0'
(there is no specific classpath and it works for me)
3) you must create 3 class (GCMPushReceiverService, GCMRegistrationIntentService, GCMTokenRefreshListenerService)
4.1) code for GCMTokenRefreshListenerService :
package com.myapp.android;
/**
* Created by skygirl on 02/08/2016.
*/
import android.content.Intent;
import com.google.android.gms.iid.InstanceIDListenerService;
public class GCMTokenRefreshListenerService extends InstanceIDListenerService {
//If the token is changed registering the device again
@Override
public void onTokenRefresh() {
Intent intent = new Intent(this, GCMRegistrationIntentService.class);
startService(intent);
}
}
4.2) Code for GCMRegistrationIntentService (change authorizedEntity with your project number) :
package com.myapp.android;
/**
* Created by Skygirl on 02/08/2016.
*/
import android.app.IntentService;
import android.content.Intent;
import android.support.v4.content.LocalBroadcastManager;
import android.util.Log;
import com.google.android.gms.gcm.GoogleCloudMessaging;
import com.google.android.gms.iid.InstanceID;
public class GCMRegistrationIntentService extends IntentService {
//Constants for success and errors
public static final String REGISTRATION_SUCCESS = "RegistrationSuccess";
public static final String REGISTRATION_ERROR = "RegistrationError";
//Class constructor
public GCMRegistrationIntentService() {
super("");
}
@Override
protected void onHandleIntent(Intent intent) {
//Registering gcm to the device
registerGCM();
}
private void registerGCM() {
//Registration complete intent initially null
Intent registrationComplete = null;
//Register token is also null
//we will get the token on successfull registration
String token = null;
try {
//Creating an instanceid
InstanceID instanceID = InstanceID.getInstance(this);
String authorizedEntity = "XXXXXXXXXX"; // your project number
//Getting the token from the instance id
token = instanceID.getToken(authorizedEntity, GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
//Displaying the token in the log so that we can copy it to send push notification
//You can also extend the app by storing the token in to your server
Log.w("GCMRegIntentService", "token:" + token);
//on registration complete creating intent with success
registrationComplete = new Intent(REGISTRATION_SUCCESS);
//Putting the token to the intent
registrationComplete.putExtra("token", token);
} catch (Exception e) {
//If any error occurred
Log.w("GCMRegIntentService", "Registration error");
registrationComplete = new Intent(REGISTRATION_ERROR);
}
//Sending the broadcast that registration is completed
LocalBroadcastManager.getInstance(this).sendBroadcast(registrationComplete);
}
}
4.3) Code for GCMPushReceiverService :
package com.myapp.android;
/**
* Created by Skygirl on 02/08/2016.
*/
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.media.RingtoneManager;
import android.os.Bundle;
import android.support.v4.app.NotificationCompat;
import com.google.android.gms.gcm.GcmListenerService;
//Class is extending GcmListenerService
public class GCMPushReceiverService extends GcmListenerService {
//This method will be called on every new message received
@Override
public void onMessageReceived(String from, Bundle data) {
//Getting the message from the bundle
String message = data.getString("message");
//Displaying a notiffication with the message
sendNotification(message);
}
//This method is generating a notification and displaying the notification
private void sendNotification(String message) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
int requestCode = 0;
PendingIntent pendingIntent = PendingIntent.getActivity(this, requestCode, intent, PendingIntent.FLAG_ONE_SHOT);
NotificationCompat.Builder noBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.your_logo)
.setContentTitle("Your Amazing Title")
.setContentText(message)
.setPriority(Notification.PRIORITY_MAX)
.setContentIntent(pendingIntent);
noBuilder.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));
NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, noBuilder.build()); //0 = ID of notification
}
}
5) Don't forget to change package name
6) In your mainActivity paste this code :
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Setup view
setContentView(R.layout.main);
mRegistrationBroadcastReceiver = new BroadcastReceiver() {
//When the broadcast received
//We are sending the broadcast from GCMRegistrationIntentService
public void onReceive(Context context, Intent intent) {
//If the broadcast has received with success
//that means device is registered successfully
if(intent.getAction().equals(GCMRegistrationIntentService.REGISTRATION_SUCCESS)){
//Getting the registration token from the intent
String token = intent.getStringExtra("token");
//Displaying the token as toast
Toast.makeText(getApplicationContext(), "Registration token:" + token, Toast.LENGTH_LONG).show();
//if the intent is not with success then displaying error messages
} else if(intent.getAction().equals(GCMRegistrationIntentService.REGISTRATION_ERROR)){
Toast.makeText(getApplicationContext(), "GCM registration error!", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(), "Error occurred", Toast.LENGTH_LONG).show();
}
}
};
//Checking play service is available or not
int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());
//if play service is not available
if(ConnectionResult.SUCCESS != resultCode) {
//If play service is supported but not installed
if(GooglePlayServicesUtil.isUserRecoverableError(resultCode)) {
//Displaying message that play service is not installed
Toast.makeText(getApplicationContext(), "Google Play Service is not install/enabled in this device!", Toast.LENGTH_LONG).show();
GooglePlayServicesUtil.showErrorNotification(resultCode, getApplicationContext());
//If play service is not supported
//Displaying an error message
} else {
Toast.makeText(getApplicationContext(), "This device does not support for Google Play Service!", Toast.LENGTH_LONG).show();
}
//If play service is available
} else {
//Starting intent to register device
Intent itent = new Intent(this, GCMRegistrationIntentService.class);
startService(itent);
}
}
//Unregistering receiver on activity paused
@Override
public void onPause() {
super.onPause();
Log.w("MainActivity", "onPause");
LocalBroadcastManager.getInstance(this).unregisterReceiver(mRegistrationBroadcastReceiver);
}
@Override
public void onResume() {
super.onResume();
Log.w("MainActivity", "onResume");
LocalBroadcastManager.getInstance(this).registerReceiver(mRegistrationBroadcastReceiver,
new IntentFilter(GCMRegistrationIntentService.REGISTRATION_SUCCESS));
LocalBroadcastManager.getInstance(this).registerReceiver(mRegistrationBroadcastReceiver,
new IntentFilter(GCMRegistrationIntentService.REGISTRATION_ERROR));
}
7) In your AndroidManifest.xml add following lines :
<uses-permission android:name="android.permission.INTERNET" />
8) in your console logcat copy your token and paste on this site
add your project number, your token and a message. It's work fine for me :)
