Problem with Admob extension

Whenever I build my game on Android when I have the Admob extension enabled the build fails. I get these two errors.

[LOG]     [javac] Note: Some input files use or override a deprecated API.
[LOG]     [javac] Note: Recompile with -Xlint:deprecation for details.

I dont get these errors with the Admob extension disabled, what do I do?

Do you still have this problem? If so, be sure to have the latest version of Stencyl 3.1 and the latest version of the AdMob extension 3. If you are still experiencing this problem, please post your logs (Debug > Logs > Generate Logs).
