SDK / exoplayer

MobileHarness allocates random devices for each test and repeats tests up to 5 times to
account for spurious test failures. Some of our tests automatically pass for SDK versions
below a certain threshold. Thus, even if such a version-guarded test would always fail,
the MobileHarness test is likely to succeed as it only needs one random allocation to a
device with a lower SDK version.

To prevent this behaviour and to make sure all tests are actually run, the mobile_test
target is split into multiple targets one for each minimum SDK version.
