I thought you where doing a shell script because you needed to start stuff in
the background, there is really nothing in here you can't do from python?

+set -x

+ninja -C out/Release pkg_packages
+cp -R out/Release/packages out/ReleaseARM/packages
+export PATH=$PATH:third_party/android_tools/sdk/platform-tools/\

Are we leaking these adb_reverse_forwarder.py processes ?

Could you record the PID and kill it after running test.py.

+sleep 15
