Sorry for the late followup, I was in vacation, and thanks for your contribution!

Note that another way to "fix" this is to point to another version of java in "Project Structure", see also #44 for yet another workaround.

I think it's OK to have (temporary?) workarounds in our samples, but a real bug should also be filed thru https://code.google.com/p/android/issues/entry?template=Tools%20bug%20report about the wrong version of java being selected by default by Android Studio.

We should probably file the issue first and reference it as a comment in build.gradle.

In the meantime can you rebase the change, and split the .gitignore and api bump in separate PR? so we can apply and review them separately.

Thanks in advance.
