How to detect phone tilt?

Question

How to determine the angle of the phone orientation in the one plane?

Now I make it through SensorManager:

mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
mOrientation = mSensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION);

...

public void onSensorChanged(SensorEvent event) {
    xy_angle = event.values[0]; 
    xz_angle = event.values[1]; 
    zy_angle = event.values[2]; 

Here I get different angles, but I need only one angle, which varies with the rotation of the phone, while driving along the blue line.

How calc or how get this angle?

How can I use SensorManager.getOrientation for tilt controls like "My Paper Plane"? - similar question here, but I don't understand how author solve his problem.

Solution 1

I see that this post is a bit old, so maybe it's been answered by now, but Sensor.TYPE_ORIENTATION is now deprecated in favor of SensorManager.getOrientation().

I've done a full writeup of essentially what you're looking for here: http://blog.samsandberg.com/2015/05/10/tilt-for-android/

Hope it helps someone looking for the same thing!

Solution 2

What you need is SensorManager.getOrientation().
