App auto rotates even with device orientation locked

问题

I am working on normal activity based application. I have turned off device orientation from device settings. When I run my app on device, the app changes orientation based on device movement. I have no clue how can an app rotate even when device orientation is locked. There is no such instance/issue reported or ever asked on stack overflow or any other forum. Please point out, what I might be missing?

It was very silly mistake, but I thought of sharing here in case any one else faces this issue. At a point, in my application, I was setting device orientation programmatically to SCREEN_ORIENTATION_FULL_SENSOR:

activityContext.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_FULL_SENSOR);

This allows app to change orientation, based on sensor, even when user has locked the device orientation.

You could check if device rotation is off or on and then lock it, like this:

if (android.provider.Settings.System.getInt(getContentResolver(), Settings.System.ACCELEROMETER_ROTATION, 0) == 1){
    //Auto Rotate is on, so don't lock

    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);
}
else{
    //Auto Rotate is off, so lock

    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
