there is something bug to onSensorChange , I was able to move my map from facing north, my code was correct but its always rotate even the phone not moving
@Override
protected void onResume() {
mSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);
mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
mMagnetometer = mSensorManager.getDefaultSensor(Sensor.TYPE_MAGNETIC_FIELD);
super.onResume();
mSensorManager.registerListener(this, mAccelerometer, SensorManager.SENSOR_STATUS_ACCURACY_LOW);
mSensorManager.registerListener(this, mMagnetometer, SensorManager.SENSOR_STATUS_ACCURACY_LOW);
}
@Override
public void onSensorChanged(SensorEvent event) {
if (event.sensor == mAccelerometer) {
System.arraycopy(event.values, 0, mLastAccelerometer, 0, event.values.length);
mLastAccelerometerSet = true;
} else if (event.sensor == mMagnetometer) {
System.arraycopy(event.values, 0, mLastMagnetometer, 0, event.values.length);
mLastMagnetometerSet = true;
}
if (mLastAccelerometerSet && mLastMagnetometerSet) {
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
SensorManager.getRotationMatrix(mR, null, mLastAccelerometer, mLastMagnetometer);
SensorManager.getOrientation(mR, mOrientation);
float azimuthInRadians = mOrientation[0];
float azimuthInDegress = (float)(Math.toDegrees(azimuthInRadians)+360)%360;
RotateAnimation ra = new RotateAnimation(
mCurrentDegree,
-azimuthInDegress,
Animation.RELATIVE_TO_SELF, 0.5f,
Animation.RELATIVE_TO_SELF,
0.5f);
updateCamera(azimuthInDegress);
}
}, 3000);
}
}
private void updateCamera(final Float bearing) {
CameraPosition pos = CameraPosition.builder().target(latLng).zoom(20).bearing(bearing).build();
mGoogleMap.moveCamera(CameraUpdateFactory.newCameraPosition(pos));
}
I already put delay 5 seconds time but its not working, Please help me thanks
