Check if android device rotation possible

I want to know if the android device supports device rotation. I thought any Android device supports the screen rotation but my Samsung Galaxy View doesn't support any rotation.

I only found this code:

if (android.provider.Settings.System.getInt(getContentResolver(), Settings.System.ACCELEROMETER_ROTATION, 0) == 1){
    Toast.makeText(getApplicationContext(), "Auto Rotate is ON", Toast.LENGTH_SHORT).show();

} else {
    Toast.makeText(getApplicationContext(), "Auto Rotate is OFF", Toast.LENGTH_SHORT).show();
}

But this only lets me know if the user set the Screen rotation off or on, I want to know if it is at all possible.

Please help me, best wishes

Solution

  • You can check availability of sensor. here is official docs

    PackageManager manager = getPackageManager();
boolean hasAccelerometer = manager.hasSystemFeature(PackageManager.FEATURE_SENSOR_ACCELEROMETER);

    Role of Accelerometer

    The accelerometer is a built-in electronic component that measures tilt and motion. It is also capable of detecting rotation and motion gestures such as swinging or shaking.

    The most common use for it is to activate auto screen rotation on mobile devices when the user changes their orientation from portrait to landscape or vice-versa.
