Question

I am creating an app where I will send the data I receive from the Android phones sensors, to another Android phone using Wifi-Direct.

I am able to get the values of the sensors by writing the code in a class that extends Activity. I have used the Sensor Manager Class.

But now I want to get the sensor values in a Background thread. Is there any way to do that?

Answer 1

You can listen for the ACTION_SCREEN_OFF event inside of an Async_Task which is great for background threads.

When the event fires inside of your Async_Task, unregister your sensor listener and then re-register it. The screen will continue to stay off, but the monitoring will continue.

Here is a relevant article and good code example on this blog
