error in App Engine connected android project

Question

I downloaded the Google plugin for eclipse with all the necessary tools. When I create in eclipse a new 'App engine connected android' Project there are immediately the following 4 errors (without touching the code) in the android project although the App engine project works fine.

• The method getDeviceInfo(String) is undefined for the type Deviceinfoendpoint in file GCMIntentService.java.

• The method insertDeviceInfo(DeviceInfo) is undefined for the type Deviceinfoendpoint in file GCMIntentService.java.

• The method listMessages() is undefined for the type MessageEndpoint
  in file RegisterActivity.java.

• The method removeDeviceInfo(String) is undefined for the type Deviceinfoendpoint in file GCMIntentService.java.

Seems that some jar or installation is missing but I checked everything and re-installed the Google plugin and all the installations and extras in the SDK manager. I also checked the versions and I think they are OK. I always get the same problem. What is wrong and what can I do?

Thank you very much for any answer!

It sounds to me like you should check that any entities have annotations, getters, setters and a default constructor. right click on any entity class you may have on the App-engine side google->generate cloud endpoints class. right click on app engine project google->generate client libraries
