监控Android设备上的GPS使用情况

Question

I am trying to set up a monitoring functionality on an Android device. I would like to monitor the actual usage of the GPS sensor on the phone. This means I am primarily not interested in when the user turns the GPS sensor on/off, but when he uses GPS data through any given app (eg maps, location based search).

I have tried the approach mentioned in Get GPS start/stop events with addGpsStatusListener , however, unsuccessfully.

It is also unclear to me whether GPS_EVENT_STARTED means a resume from standby of the sensor, or simply reflects toggling the "allow GPS" in the settings by the user. (see: http://developer.android.com/reference/android/location/GpsStatus.Listener.html )

Would someone know:

a) whether such a functionality is implementable/has already been implemented

b) how this could be accomplished?

Many Thanks.

Answer 1

After excessive testing of several approaches (a selection):
How can I enable or disable the GPS programmatically on Android?
Android Enable and Disable GPS
How to programmatically enable GPS in Android Cupcake
How to enable GPS in android coding

I found that on Android v4.2.2 it was indeed not possible to toggle the GPS status (regardless of what exactly the status implies, as also asked in my question). I particularly found a comment in question How can I enable or disable the GPS programmatically on Android? to be misleading . Even if the exploit with the power control widget should have reemerged in 4.2.2, it has since been fixed .
