Question

I have an activity with a button “start measuring”: pressing it will register this activity as sensor lister.
However, I discovered that if user does not interact with it for a while screen turns off and android disables sensor listenig (in order to save battery I guess).

I discovered that it’s a bit tricky to have a background thread listen for sensor events too and, as it’s not a problem, I simply want to disable turning off while listener is on, and enable it again when user presses “stop measuring”.

Answer 1

I had an activity that used the sensor only and the screen would turn off, i used

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

and to turn off

getWindow().clearFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

In the resume and pause of my activity
