Migrate from C2DM to GCM for Android SDK 19

Question

I have an application for Android SDK 19, which is written for using C2DM. And I need to migrate it to GCM. I faced with next problems:

1. Actually there is no /extras/google/google_play_services/libproject/google-play-services_lib/ folder. As I understand from here it was replaced by Google Repository library and split into different parts
2. GCM located into obsolete library Google Cloud Messaging
3. I have some google-play-services_lib (downloaded from somewhere android:versionCode="3265130" android:versionName="3.2.65 (834000-30)" uses-sdk android:minSdkVersion="8") but when I try to import this library into project I receive java.lang.ClassNotFoundException error after build on TeamCity side

The questions are:

1. Is there is a possibility to use old google-play-services_lib under new Android OS if I include this old lib into my project?
2. Is there is a possible way to use GCM by using old google-play-services_lib?
3. What I do wrong with importing google-play-services_lib?

Answer 1

I advise you to follow this guide Migrate a GCM Client App for Android to Firebase Cloud Messaging: https://developers.google.com/cloud-messaging/android/android-migrate-fcm

Firebase: https://firebase.google.com/

I think that this guide is very useful and helpful.

Answer 2

instead of using GCM try to migrate to firebase

google now recommends to use firebase notification
