Android didUpdateHeading (fate manager)?

Question

Does Android have the equivalent of didUpdateHeading (from iOS)? Any sample code to rotate an image using it?

I searched a lot, but could not get a useful hint.

Thanks in advance.

Edit: Let me tell you about my question: on iOS, when the device changes the title, the delegate object gets called by its method: "didUpdateHeading". In Android, I could find "onLocationChanged" to get the coordinates, but not the title. How to get header information in Android?

It should be what you are looking for. The OnSensorChanged method should provide the same functionality. (float)event.values[0] - your title.

Just read your thanks text. This is the only way to do this, from everything I have researched, and from my experience in general. For example, I brought you what you need pretty quickly, with copy and paste.

If you need a real-time header, you should go with @ jack57's answer and use the G-sensors in the device.

If you only need a heading, when you get a new location, you can get it using Location.getBearing() , but note that this only works with GPS coordinates, if you got the coordinate from LocationManager.NETWORK_PROVIDER , then the bearing will be 0.
