Develop Reference

I am able to generate the token using FCM in Android but when I am sending the message it is getting failed

I have generated the token but still unable to get the notification.
When I am sending the message to the User Segment it is showing status as completed but I did not receive any notification.
I am uploading my manifest file.

In push notification when user clear the app from the task manager the notification is not coming?

I am using push notification in my app. it is working fine when the app is running or in the foreground state.but when the user clean the app from the task manager/tab then the notification is not coming. I tried many method like package restart and all. but i could not get the solution. if anyone know what i am doing wrong. please tell me.
This is my GcmBroadcastReceiver class :-
public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent)
{ ComponentName comp = new ComponentName(context.getPackageName(),
GcmIntentService.class.getName());
startWakefulService(context, (intent.setComponent(comp)));
setResultCode(Activity.RESULT_OK);
}
}
This is GcmIntentService class by which i send the notification :-
public class GcmIntentService extends IntentService {
public static final int NOTIFICATION_ID = 1;
private NotificationManager mNotificationManager;
private final static String TAG = "GcmIntentService";
private Context mContext;
public GcmIntentService() {
super("GcmIntentService");
}
#Override
protected void onHandleIntent(Intent intent) {
Bundle extras = intent.getExtras();

if (!extras.isEmpty()) {
if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR

} else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED

Thread.sleep(5000);

}
}

sendNotification(extras.getString("message"));
}
} // Release the wake lock provided by the WakefulBroadcastReceiver.
GcmBroadcastReceiver.completeWakefulIntent(intent);
} // Put the message into a notification and post it.
private void sendNotification(String msg) {
mNotificationManager = (NotificationManager) this
.getSystemService(Context.NOTIFICATION_SERVICE);
Intent intent = new Intent(this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);
intent.putExtra("KEY","aman");
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

I have checked your AndroidManifest.xml you have not defined your broadcast receiver and GcmIntentService class as service.

GCM message not arriving until App is either running or in background

I have successfully implemented GCM and messages successfully arrive to my devices when the App is in running and background states.
But when the App is in a closed state, some devices receive the message and some do not. To get the message, I have to start the application again.

If you "force close" an app, then it will become unresponsive to all broadcasts until the user starts it again.
If you "remove from recents" (like on some devices, long hold the "home" key) then this is not a force close, and even if the app is in the background, it will continue to receive messages.
See this post here: Will I receive GCM messages if Android kill my app and if I do a Force Close from the settings?

GCM messages are not received on android 2.3.6 v but working fine on android 4.X v

My GCM client is able to register on all versions but messages are received on android above 4.x versions, not on android 2.3.6. I have made many changes but I cannot figure this problem out please help me, thanks in advance.

If you are using product flavors maybe you have the same problem than I found.
I found that when using flavors with diferent applicationId, then your package in the AndroidManifest file for the permission and the category is not correct.
And this does not matter for Android 5.x, but for Android 2.3 causes that the broadcast receiver will never be called.
The solution I found is use the gradle's placeholder support. Using ${applicationId} the issue is resolved for all the Android versions.
build.gradle:
productFlavors {
prod {
applicationId 'com.democlientapp'
}
dev {
applicationId 'com.democlientapp.dev'
}
}
AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

Use Latest dependency/library for GCM for sdk version 4 or heigher
compile "com.google.android.gms:play-services-gcm:10.2.0"
in build.gradle file in dependency.
and add build.gragle level file
classpath 'com.google.gms:google-services:3.0.0'
its works for hiegher versions.
