I started testing the new version and one of integration test failed, when I try to build library by maven.

Thank you,
Added some filtering to not to call stringSet related calls on pre API 11 devices.
Can you please also test this?
I was testing with a 2.3.3 x86 emulator, 4.1 emulator, sgs4. Now it does not fail.

btw: opened a ticket for supporting string sets: Issue #9
