If not argument is given, the app just sits and wait for stdin input, this can be confusing for the user. Add logic to display menu if no argument is given. Test: metrics_dump display menu Test: metrics_dump [bugreport from sabrina-q.gz] display mediadrm and widevine metrics Test: metrics_dump --mediadrm [adb shell dumpsys media.metrics output] display mediadrm metrics Test: metrics_dump --widevine [adb shell dumpsys media.metrics output] display widevine metrics Test: metrics_dump [bugreport from sabrina-q.gz] --widevine display menu because the order is app_name, options, input file Bug: 180983850 Change-Id: I9b35f782d8f59663661148d3950f89e4724b6bce
