I'm following the Google Tutorial to install Push Notification on Android. I'm using Google Play Services Module because the Google Cloud Messaging was recently deprecated.

Tutorial : Google Cloud Messaging - Google Play Services

But when I launch the app I have this errors :

I never played with the push notifications but I'm working with the google play services. You should add the google-play-services_lib folder as a separate project and add it as a library into your Android project.

  1. Import the google-play-services_lib (also tick the copy to workspace). You can find the google-play-services_lib in the sdk floder -> extra > google -> google_play_services -> libproject -> google-play-services_lib

  2. Set the newly created project as a library (in eclipse -> build path -> android -> tick the "is Library" and ok.

  3. Go to the build path of your android project -> android -> add -> add the google-play-services_lib library you just created.

I hope it helps (-:

You should not copy google-play-services.jar directly into your project. Instead you need add reference to

[android-sdk]\extras\google\google_play_services\libproject\google-play-services_lib

library t your project. To do this please follow item 4 of these instructions. In Android Studio there should be similar procedure.

The reason is GPS library refers to it's own (com.google.android.gms.R) resources from precompiled JAR.

  • Thanks for your help. I added the `google-play-services_lib` as an module in my project and I removed the jar but know I can't compile : `com.google.android.gms.* not found.` :s – Kevin Machado Nov 06 '13 at 14:53
  • I added again the .jar and now I can compile. The `google-play-services_lib module` is still in my project but the same error occurred. – Kevin Machado Nov 06 '13 at 15:01

    Looks like you missed something. You definitly should not copy jar file manually. Try to follow [these](http://stackoverflow.com/a/16639227/1992063) steps to integrate library to your project. – Alexey Ivanov Nov 06 '13 at 16:50

I was just working on this same issue the last couple days. My issues were related to the Drive API, but the solution would potentially help regardless of which part of the Google API you're using.

I use IntelliJ IDEA for my development as well. What I had to do was call up the Project settings and add some additional dependencies to my app. Referencing the Google Play Services JAR file is one part of this. To get the resources, you need to reference the project itself so it compiles the R class for Play Services. Here's what I did:

  1. Imported a module that referenced the google-play-services_lib for the source
  2. Opened Module Settings for my app module
  3. Clicked the Dependencies tab
  4. Added a new "Jars or Directories" dependency
  5. Browsed to the SDK location for google-play-services.jar and referenced it
  6. Added a new Module dependency that referenced the project for google-play-services_lib

FYI, I have the google-play-services.jar reference as a global library, so I can actually include it easily in any project, but that's not necessary for this to work. You just need to have references to both the JAR and the module to get it to compile the Play Services resources object.

In my proguard.cfg file for my app project, I added this:

-keep public class com.google.android.gms.**

The Proguard configuration modification may not be necessary.

After I made these changes, it came together pretty quickly. I will say that Google's API documentation for implementing calls to their API is VERY out of date and incorrect. They mention referencing the JAR, but don't say anything about referencing the project. I vaguely remember them glossing over the fact that you need to actually compile a jar manually yourself, but it's not clear exactly what you need to reference in their documentation.

Hope this helps!
