I'm currently trying to replace my 'Sensor.TYPE_ORIENTATION' because it was deprecated.
So Android Documentation lacks most of the Information, on how to do it. While debugging and diggin here on SO I figured out how to calculate the azimuth
which was once provided by the OrientationSensor.
I do it in this way:
float accelerometerVals[] = new float[3];
float magneticVals[] = new float[3];
float orientationSensorVals[] = new float[3];
float rotationMatrix[] = new float[16];
float orientation[] = new float[3];
@Override
public void onSensorChanged(SensorEvent event) {
switch (event.sensor.getType()) {
case Sensor.TYPE_ACCELEROMETER:
System.arraycopy(event.values, 0, accelerometerVals, 0, 3);
break;
case Sensor.TYPE_MAGNETIC_FIELD:
System.arraycopy(event.values, 0, magneticVals, 0, 3);
break;
case Sensor.TYPE_ORIENTATION:
System.arraycopy(event.values, 0, orientationSensorVals, 0, 3);
break;
default:
break;
}
if (null != magneticVals && null != accelerometerVals){
SensorManager.getRotationMatrix(rotationMatrix, null, accelerometerVals, magneticVals)
SensorManager.getOrientation(rotationMatrix, orientation);
float azimuth = Math.toDegrees(orientation[0])
//this calculation gives me the Azimuth in the same format that OrientationSensor
azimuth += (azimuth >= 0) ? 0 : 360
float FALSE_PITCH = Math.toDegrees(orientation[1])
float FALSE_ROLL = Math.toDegrees(orientation[2])
}
Note the variables FALSE_PITCH && FALSE_ROLL. I don't have no idea how to "normalize" (values differ from +10 to -10) this values, to get the same output than I had before inside my OrientationSensor
I've been through the same problem but I'm surprised your roll is not right, as it is for me. Here's what I used :
//Let values[] be your orientation[] variable once in degrees.
// Azimuth scaling
if (values[0]<0) values[0] += 360;
// Pitch scaling
if (values[1]<-90) values[1] += (-2*(90+values[1]));
else if (values[1]>90) values[1] += (2*(90-values[1]));
// Roll scaling
// NOT NEEDED
Would you be able to post some outputs of both Orientation sensor and your degrees orientation[] variable ?
