Refactored all uses of Guava Joiner to use String.join()

This isn't particularly necessary persay, but String.join() fully
replaces the Guava class and is in the standard library now.

Updated remove an unused variable and fix some formatting (though ~all
of the formatting changes were from google-java-format).

Fixed formatting error due to skipping the repo hook (since I thought
it formatted whole files).

Trade Federation (TF / Tradefed)

TF is a test harness used to drive Android automated testing. It runs on test hosts and monitors the connected devices, handling test scheduling & execution and device management.

Other test harnesses like Compatibility Test Suite (CTS) and Vendor Test Suite (VTS) use TF as a basis and extend it for their particular needs.

Building TF:

  • source build/envsetup.sh
  • tapas tradefed-all
  • make -j8

If you are a tests writer you should start looking in the test_framework/ component which contains everything needed to write a tests in Tradefed.
