I'm building app on Raspberry Pi with Android Things and I have 7 inch touch screen, but the screen never turns off.
Is it possible to set timeout like in Android phones? or force it to turn off/on.
If I remove the power line and inserted again the screen, it will not work until I reboot.
There are two system settings that control this process: STAY_ON_WHILE_PLUGGED_IN and SCREEN_OFF_TIMEOUT
The STAY_ON_WHILE_PLUGGED_IN
setting is set to BATTERY_PLUGGED_AC
by default. You can programmatically change this value in your application code with the Settings
API:
Settings.Global.putInt(getContentResolver(),
Settings.Global.STAY_ON_WHILE_PLUGGED_IN, 0);
You can also make this change from the command line if it is more convenient:
$ adb shell settings put global stay_on_while_plugged_in 0
