SensorManager only working on some devices
0
I have the following code to get the x and y angle of my device and it is working fine on my phone, but not my tablet (Samsung galaxy tab e). I was wondering if anyone had any idea as to what could be causing it to work on one device but not another.
I did also ensure that screen rotation was enabled on both. My assumption is that the tablet is lacking a sensor, and what I'm looking for most is a workaround. Any help would be much appreciated. Thanks in advance!
Source code:
double yAngle;
double xAngle;
@Override
protected void onResume() {
super.onResume();
sensorManager.unregisterListener(this);
sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_ROTATION_VECTOR),RATE);
}
@Override
public void onSensorChanged(SensorEvent event) {
float rotationMatrix;
rotationMatrix = new float[16];
SensorManager.getRotationMatrixFromVector(rotationMatrix, event.values);
determineOrientation(rotationMatrix);
lblY.setText(String.format("%.1f", yAngle));
lblX.setText(String.format("%.1f", xAngle));
}
private void determineOrientation(float rotationMatrix){
//CREATING FLOAT ARRAY OF ORIENTATION VALUES
float orientationValues = new float[3];
SensorManager.getOrientation(rotationMatrix, orientationValues);
yAngle = Math.toDegrees(orientationValues[2]);
xAngle = Math.toDegrees(orientationValues[1]);
}

sensorManager.getDefaultSensor(Sensor.TYPE_ROTATION_VECTOR)returnsnullwhen the sensor is not supported by the device. You can log its value to see whether it returnsnullin the tablet or not ?

It does indeed return null on the tablet. Would you know if there are other sensors that can be used? Thanks

sensorManager.getDefaultSensor(Sensor.TYPE_ROTATION_VECTOR)returnsnullwhen the sensor is not supported by the device. You can log its value to see whether it returnsnullin the tablet or not ?

It does indeed return null on the tablet. Would you know if there are other sensors that can be used? Thanks
