Hello,
what is the magic with wake locks?
I try to prevent that the phone is going to sleep.
Here my code (snippet):
public class GPSListenerHandler extends Handler implements
GpsStatus.Listener, LocationListener {
private WakeLock wakeLock;
protected boolean isWakeLocked;
public GPSListenerHandler(Looper l, Context c) {
super(l);
// ...
final PowerManager mgr = (PowerManager)
c.getSystemService(Context.POWER_SERVICE);
this.wakeLock = mgr.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,
"GPSListener");
}
@Override
public void handleMessage(Message msg) {
if (msg.arg1 == GPSTrackingService.START) {
this.wakeLock.acquire();
this.isWakeLocked = true;
this.tracking = true;
startLogging();
} else if (msg.arg1 == GPSTrackingService.STOP) {
if (this.isWakeLocked) {
this.wakeLock.release();
}
this.tracking = false;
stopLogging();
}
}
// ...
}
Now my Android 2.3.x devices going to sleep after round about 10
minutes, my 4.x devices stay awake.
What's wrong?
Ralph
