I am aware that other people have tried to resolve this issue but have thus far found a suitable answer.
The error is, on start up, eclipse gets hung up on \"Android SDK
figured it out a couple days ago and forgot to inform y'all.
all I needed to do was save the projects to some other directory if you have not already. Delete it from your workspace and also delete the app engine endpoints project.
Re-import the android project and copy into workspace. set the java build path and everything else (if it says 'project master' control click -> team -> disable) everything should look fine. Then, delete all references to the app engine project, this means folders called 'endpoint-libs/libcontainers...'
This will break your project everywhere you reference the data model
Now, re-import the app engine project and make any necessary changes so that it doesn't have build errors (warnings may be OK).
Control click -> generate cloud endpoint client library. The libraries in the original project will be replaced.
Not entirely sure what caused this but for the time being it has been working beautifully.
