"""
This script is for running the Android tests on android devices from the build
server. It may take as a parameter the build number (e.g. the build number from
Jenkins). The build number may also be a string.
The script removes all the apps whose ids contain "mapswithme", and cleans up
the device logs before running the tests, so make sure you don't have important
logs on devices before you connect them to the server. After the test, the
device logs are filtered and saved as <build number>_<device_id>.log in the
current directory.
