WakeLock_WifiLock_Exerciser
Small application to test functionality of WifiLock and WakeLock on Android
EMDK Dependency
Application will run on both Zebra and non-Zebra Android devices. When running on Zebra devices the application will take advantage of MX to enable or disable battery optimizations via buttons on the UI. This does require:
- EMDK to be installed on your build machine (https://www.zebra.com/us/en/support-downloads/software/developer-tools/emdk-for-android.html) Version 6.7 or higher (though I had it working with EMDK 6.6 in testing)
- A device that supports MX7.x which as the numbering implies will be at least Nougat. You can check the MX level from Settings --> About --> SW components --> MX (MXMF version)
- A device whose MX supports BatteryOptimization. Some features of MX are not available on Zebra's value tier devices (e.g. TC2x). Please check http://techdocs.zebra.com/mx/ for compatibility.
This only affects the bottom two buttons on the UI which refer to controlling BatteryOptimizations via MX
Repository includes a small python 3 server to receive posts from the application
python dummy-web-server.py
Determine current wake / wifi locks in effect as follows:
adb shell dumpsys power
adb shell dumpsys wifi
Optionally, force the device power state to idle as follows:
adb shell dumpsys battery unplug
adb shell dumpsys deviceidle force-idle
(verify with) adb shell dumpsys deviceidle (& observe mState)
Notes
- Uncomment the annotated line in onCreate() to create a separate wake lock on launch
- Tested on TC51
- Would never pass PlayStore criteria as includes
ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS - Make sure nothing else on your device holds wake locks before running tests
- Zebra devices also have additional settings to keep wifi on during standby (under advanced WiFi settings)
