     30 # This script executes the passed command line on Android device
     31 # using 'adb shell' command. Unfortunately, 'adb shell' always
     32 # returns exit code 0, ignoring the exit code of executed command.
     33 # Since we need to return non-zero exit code if the command failed,
     34 # we augment the passed command line with exit code checking statement
     35 # and output special error string in case of non-zero exit code.
     36 # Then we parse the output of 'adb shell' and look for that error string.
