Are there app templates for Android?

Question

Android

Guys tell me. Somewhere you can find it, or someone might be generous and share the source code of the application (template), even the most stupid one. Where the mechanism of push notifications through GCM is implemented and how it will describe in detail the implementation process.

Answer 1

IntelliJ Idea -> File -> New -> Import sample
There are a lot of application examples there, and maybe there are pushes too
But I didn’t find any better documentation in my time

Answer 2

Where can there be examples? Maybe in the official documentation?
Well, they really are there .
