[android-developers] Re: Orientation in landscape
I've tried the API demo's as well as other apps on the store but they
all react the same. Must be an issue with the phone. It's the htc
wilfdfire on vodafone.

sensor to see if they work? Have you tried other applications from Market
on it that are known to work?

Thanks for pointing me at the post, it makes sense.
However I'm still only ever getting negative degrees when the phone is
in landscape no matter which direction I'm sitting.
I did try and find the function Display.getRotation() but I can't seem
to use that function. I am using getRotationMatrix which is what
everyone else is using in the examples I've seen.
Anyone got any idea's why my phone is always telling me that North is
somewhere to my right when it's in landscape? Or is it a fault with
the phone? I'm using the wildfire google version 2.2.1.
Thanks

Hi guys,
I've been playing around with orientation (especially in relation to
the real world so finding north is very useful) and started with the
google api example.
While investigating how to change that so it worked while the phone
was in landscape I found out that I was using depricated components.
So now I'm using the acceloromiter and the magnetic field to find the
orientation which I found in a mixture of examples on the web.
This again works great while in portrain but landscape gives weird
answers?
I've done some experiments with looking at the different between
landscape and portrait but can't seem to find out what's going on and
how to correct the app to allow me to switch between portrain and
landscape on the fly.
I don't think it's quite as simple and minusing 90 degrees but I'm
willing to be wrong.
Here's my SensorListener onSensorChanged
int type = event.sensor.getType();
float[] data;
if (type == Sensor.TYPE_ACCELEROMETER) {
data = mGData;
} else if (type == Sensor.TYPE_MAGNETIC_FIELD) {
data = mMData;
}
for (int i=0 ; i3 ; i++){
data[i] = event.values[i];
}
SensorManager.getRotationMatrix(mR, mI, mGData,
mMData);
SensorManager.getOrientation(mR, mOrientation);
float incl = SensorManager.getInclination(mI);
String endl = System.getProperty(line.separator);
if (mCount++ 50) {
final float rad2deg = (float)(180.0f/Math.PI);
mCount = 0;
txZ.setText(Azimuth: +
(int)(mOrientation[0]*rad2deg) +
degrees + endl +
Pitch: +
(int)(mOrientation[1]*rad2deg) + degrees + endl +
Roll: +
(int)(mOrientation[2]*rad2deg) + degrees + endl +
incl: + (int)(incl*rad2deg));
}
Many Thanks
Michael
