SCREEN_ORIENTATION_LANDSCAPE upside down - Why?

Question

I am using the following code to set orientation locking per user preference:

 private void doLock(boolean locked) {
     if (locked) {
       int o = getRes         


        

Answer 1

try with universal landscape orientation

private static final int ORIENTATION_90 = 1;
private static final int ORIENTATION_0 = 0;
private static final int ORIENTATION_180 = 2;
private static final int ORIENTATION_270 = 3;

switch (orientation)
    {
      default:
      case ORIENTATION_0: // Portrait
        //dostuff
        break;
      case ORIENTATION_90: // Landscape left
        //do stuff
        break;
      case ORIENTATION_180: // Upside down.
        //do stuff
        break;
      case ORIENTATION_270: // Landscape right
        //do stuff
        break;
      }
