I'm searching for a compass example for Android. All I need to do is to get the correct bearing (in portrait & landscape mode).
I already found several samples, some use only
Sensor.TYPE_ORIENTATION is deprecated.
The documentation says you should use
So you should read from
Sensor.TYPE_ACCELEROMETER as well as from
Sensor.TYPE_MAGNETIC_FIELD, and then call
SensorManager.getRotationMatrix() and finally
SensorManager.getOrientation() which will return you the orientation of the phone.
From there if you see this diagram it is trivial to get the phone's orientation. This is probably what your second example does, but I don't know because you didn't show me what it is.
