Hello Marco, Thanks for the response.

Saldy I already have that in the manifest (Using your last month unity 5.0 plugin).

If it helps here's my manifest:

My only other guess is maybe that you have moved the .AAR files to another location other than their original installation location. I'm not exactly sure what is going on in your particular situation.

I have created this video, it is a bit raw, but it shows implementing our Android Push Notification Plugin from scratch. be warned, since this is unedited it is about 54 minutes long.

https://www.youtube.com/watch?v=ObdhM3Q9oaw&feature=youtu.be

See if you are doing something different than I am in this video.

I just ran into a similar issue (with identical symptoms). It turns out that the problem had to do with queued notifications being delivered in one go. Given messages A and B:

onMessageReceived(A)
onMessageReceived(B)
onReceive(A) -- kablewy!

It seemed to be some PendingIntent weirdness related to FLAG_UPDATE_CURRENT. When the messages are queued up like this, the intent passed to NotificationPublisher.onReceive has missing extras.

I 'fixed' this by removing the plugin, adding the code from GitHub to my project, and modifying PlayFabNotificationSender.send to call context.sendBroadcast(notificationIntent); instead of the alarm manager for local notifications.

We are having a very similar error with our game now on Android.

We've re-implemented things several times now trying to determine what is going wrong. I can confirm that we have the receiver configured in our manifest as was suggested above. The AAR files are in Plugins/Android as they should be.

Is there anything else I should check?

@Ian Oliver do you know if your change was rolled into the plugin since you suggested it?

@ryan While I have not had a chance to look into the issue, I know for a fact we won't be rolling Ian's change into the plugin. This is primarily because we need the Alarm manager to have support for scheduled push notifications.

I should be able to get to looking at this maybe sometime next week.

Ok, that makes sense. I'm just trying to wrap my head around some of the issues we're having currently. On some devices we are able to receive GCM messages without issue, while on others receiving a push message causes the app to crash with several error messages (such as "Class not found when unmarshalling: com.playfab.unityplugin.GCM.PlayFabNotificationPackage"). We've confirmed repeatedly that the packages are pulling in, the manifest we are using is generated by the Playfab plugin, with a few additions for Google Play Services.

Are there any other things we should check that we might be missing?

@MarcoWilliamsPF @ryan Managed to fix the problem. Notifications now show on all devices.

What I did was wrap the extras in a bundle as suggested here (http://stackoverflow.com/questions/28589509/android-e-parcel-class-not-found-when-unmarshalling-only-on-samsung-tab3)

Also, Bundle internals are not touched by any device till needed. (as seen here: http://stackoverflow.com/questions/2307476/classnotfoundexception-when-using-custom-parcelable/21141830#answer-21141830)

To fix it modify the following classes:

In NotificationPublisher.java, I added

Bundle bundle = intent.getBundleExtra(NOTIFICATION);
PlayFabNotificationPackage notification = bundle.getParcelable(BUNDLE_ID);

Also commented out the String notificationId because it's not being used.

In PlayFabNotificationSender.java : methods Send, ScheduleNotification, CancelScheduledNotification, I added

Bundle bundle = new Bundle();
bundle.putParcelable(NotificationPublisher.BUNDLE_ID, notifyPackage);
        
Intent notificationIntent = new Intent(intent, NotificationPublisher.class);
notificationIntent.putExtra(NotificationPublisher.NOTIFICATION, bundle);

Build with gradle and it's ready.
