Thread: Electronic compass on iGO?

And after with utilities with lua code.
Here is an example which
Enable internal compass
In java.
This must be in the primo apk.


Java example...

import android.content.Context;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;

public class InternalCompassOrientationProvider implements SensorEventListener, IOrientationProvider
{
private IOrientationConsumer mOrientationConsumer;
private final SensorManager mSensorManager;
private float mAzimuth;

public InternalCompassOrientationProvider(Context context)
{
mSensorManager = (SensorManager) context.getSystemService(Context.SENSOR_SERVICE);
}

//
// IOrientationProvider
//

/**
* Enable orientation updates from the internal compass sensor and show the compass.
*/
@Override
public boolean startOrientationProvider(IOrientationConsumer orientationConsumer)
{
mOrientationConsumer = orientationConsumer;
boolean result = false;

final Sensor sensor = mSensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION);
if (sensor != null) {
result = mSensorManager.registerListener(this, sensor, SensorManager.SENSOR_DELAY_UI);
}
return result;
}

@Override
public void stopOrientationProvider()
{
mSensorManager.unregisterListener(this);
}

@Override
public float getLastKnownOrientation()
{
return mAzimuth;
}

//
// SensorEventListener
//

@Override
public void onAccuracyChanged(final Sensor sensor, final int accuracy)
{
// This is not interesting for us at the moment
}

@Override
public void onSensorChanged(final SensorEvent event)
{
if (event.sensor.getType() == Sensor.TYPE_ORIENTATION) {
if (event.values != null) {
mAzimuth = event.values[0];
if (mOrientationConsumer != null)
mOrientationConsumer.onOrientationChanged(mAzimuth, this);
}
}
}

I do not know where you found this, or you did, but iGO will use the language program. LUA.This language, born in Brazil 20 years ago, lua = moon. is this language that you write tools iGO Win& Android. example. for compass is this :
