Using getRotationMatrix and getOrientation in Android 2.1

Question

I\'ve been having issues with this for far too long. This code should output dx,dy,dz for the accelerometer, and a running total of the dx. It should also output azimuth,

Answer 1

I might be missing something (and you may have solved this already), but to me it looks like your switch statement is incorrect:

switch (event.sensor.getType()) {
        case Sensor.TYPE_ACCELEROMETER:
            accelerometerValues = event.values.clone();
        case Sensor.TYPE_MAGNETIC_FIELD:
            geomagneticMatrix = event.values.clone();
            sensorReady = true;
            break;
        default:
            break;
    }

If your sensor event is TYPE_ACCELEROMETER the values from the event will be cloned to both accelerometerValues and geomagneticMatrix and sensorReady will be set to true. I think you may need to change the order of this block, or possibly add a break; after your first case.
