It doesn’t break android-21 since the sources in the current repo do not support it.

I’ll push this change for android-19 which is a subset of changes required for android-21.

Keep in mind that if you build with android-21, you won’t be able to run the Java binaries
on any Android 4 based device.

If you want to research #ifdefs that we can use to allow building on API 21 while preserving
the ability to build with older APIs, please do then we can apply conditional changes to the other 
files from my previous changeset.
