Hi.
I've checked the doc here:
http://developer.android.com/guide/topics/manifest/uses-feature-element.html
and found 2 most relevant features:
1) android.hardware.sensor.accelerometer
2) android.hardware.sensor.compass
Which one do I need to specify in my manifest? Or both?
Yes, I'm sure I'm using the accelerometer. But the Accelerometer and
Magnetic Field values are also used to calculate "Direction" (which
also means I'm using android.hardware.sensor.compass ??)
Here's my code:
@Override
public void onSensorChanged(SensorEvent event) {
int type = event.sensor.getType();
switch (type) {
case Sensor.TYPE_MAGNETIC_FIELD:
mags = event.values.clone();
break;
//I'm using Accelerometer here
case Sensor.TYPE_ACCELEROMETER:
accels = event.values.clone();
break;
}
SensorManager.getRotationMatrix(rotationMat,
I, accels, mags);
SensorManager.getOrientation(rotationMat,
calculatedOrients);
//I also get direction here, So do I need to specify
android.hardware.sensor.compass in <uses-feature> ?
azimuthZ = (float) Math.toDegrees(calculatedOrients[0]);
pitchX = (float) Math.toDegrees(calculatedOrients[1]);
rollY = -(float) Math.toDegrees(calculatedOrients[2]);
}
Thank you in advance!
