Act as a proxy for calls the adb. During automated testing we have
|
|
seen the adb process hang and not return for no apparet reason. Subsequent
|
|
calls of the exact same adb command to the same device will suceed. The
|
|
purpose of this is to handle all calls to adb, kill the adb call if the
|
|
execution time takes long than a specififed number of seconds and repeat
|
|
the call a specified number of times.
