 # On Android we build unit test bundles as shared libraries.  To run
 # tests, we launch a special "test runner" apk which loads the library
 # then jumps into it.  Since java is required for many tests
 # (e.g. PathUtils.java), a "pure native" test bundle is inadequate.
 #
 # This script, generate_native_test.py, is used to generate the source
 # for an apk that wraps a unit test shared library bundle.  That
 # allows us to have a single boiler-plate application be used across
 # all unit test bundles.
