Hello! I'm working in an Android app for which i need to receive push notifications. I've followed the instructions on the documentation to implement a GCM client (https://developer.android.com/google/gcm/client.html) and so far I managed to register my device and get the registration ID. But the problem is that the WakefulBroadcastReceiver is not receiving anything, so the onReceive method is never called and my IntentService never starts so i don't get to see the notification.
Has anyone have this problem?

App icon change, if part of an update, does not seem to change on launcher and also on the app list. Upon phone restart, I could see the new icon.

What is the best practice to provide the app icon update? All I did was to replace the old icon files in mipmap folders.

Android Dev virgin here. I'm trying to build my first simple photo sharing app but I need some guidance on how to start. I've tinkered with setting up the Facebook login and the UI but I now see that what I am missing is the experience to know what to start with and what order of building is the most efficient way to make a photo sharing app. I know it would come down to the specifics of the app but let's say I wanted to make a clone of Snapchat. Could someone with a lot of Android dev help me out here? What are some of the Do's and Dont's of Android dev and what should definitely start with vs. what should I definitely NOT start with?

Could someone please help me figure this out... I kid you not when I say I've been trying to figure this out for two straight days now. I've tried nearly everything possible online and I'm looking for someone who could of possibly had a similar issue. Android studio is displaying "Rendering Problems" In all of my layouts. Has anyone encountered something similar and what steps you took to solve this?

I'm hoping that someone can help me out. I'm trying to understand OAuth2.
basically, i'm trying to build an app that uses AccountManager, and will interact with my own OAuth2 server.
so i'm using this site to set up the server:
http://bshaffer.github.io/oauth2-server-php-docs/cookbook/
now, what i'm not understanding, is how the client will authenticate the user with the server, I see from the documentation, how the client is authenticated, but what about the user credentials?
from the android side, i'm using this site for guidance:
https://udinic.wordpress.com/2013/04/24/write-your-own-android-authenticator/
I understand that, hopefully once I can find out how to authenticate the client with my OAuth2 server, things will start to fall into place.
If anyone has any guidance, I would truly appreciate it.

I used node.js for the oauth server (with oauth2orize and passport modules). This made it quite easy to set up the server. There are a couple of tutorials on how to setup the node side (eg. http://aleksandrov.ws/2013/09/12/restful-api-with-nodejs-plus-mongodb/).

On the android side, I only implemented the strategies needed by my server (Basic, AccessToken and a way to refresh the token).
