Community Guidelines
Welcome to the official Android Development community on Google+. This community is a place where all Android developers can help one another, share resources, and make us all better developers.

However, that means that this is not the appropriate place for certain types of posts:
- Spam
- Soliciting
- Recruiting
- Promotional posts
- ROM, theme, and icon pack development
- Posts about new devices, system updates, rooting devices, etc
- Posts without any text
Posts of this nature may be removed without warning or result in being banned from the community.

In addition, there are a number of other official communities for certain topics:

Here’s an overview of some of the specific categories available:

Help Center
Running into issues? Here’s where to post. If you’re having implementation problems, consider posting a link to a http://stackoverflow.com question with your code and any logcat errors. If you’re trying to find the right approach to a problem, consider searching for resources first: you’ll be a lot more successful saying “I’m looking at library Y to implement Z in my app. Is that the best way to do it?’ compared to “How do I do Z?”

Development Patterns
The various APIs give you the building blocks you need to build awesome apps. Development patterns are the instructions on how to assemble those building blocks. Guides, tips, and gotchas all belong here!

Tools and Libraries
Have a favorite tool or library that has saved you time and effort? Share it with the community!

Open Source Apps
One of the only things better than finding an awesome interaction pattern or functionality in an app is finding out exactly how they did it. Make sure you include a link to the source code when posting your favorite open source apps here.
