Testing your app with Doze

adb shell dumpsys deviceidle enable

Force the system into idle mode by running the following command:

adb shell dumpsys deviceidle force-idle

When ready, exit idle mode by running the following command:

adb shell dumpsys deviceidle unforce

Force the app into App Standby mode by running the following commands:

adb shell dumpsys battery unplug
adb shell am set-inactive <packageName> true

Simulate waking your app using the following commands:

adb shell am set-inactive <packageName> false
adb shell am get-inactive <packageName>
