Force android screen Orientation depending on screen size

Question

I am writing an application that allows users to select various things on the screen. On large 10 inch screens this looks best in landscape so I force landscape in the manifest file.

However, I want to make the application friendly for users of 8 (or 7) inch tablets as well. On these screen sizes the application should be forced in portrait mode.

Does anyone know how I can force the screen orientation depending on the screen size?

Answer 1

To find out if the device is a 7, 8 or 10 inches tablet, you can check this.

One way you can manipulate the device orientation is in every activity, after onCreate(), like this:

    // set the orientation of the device
    if(isTabletWith10Inches) {
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    } else {
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    }
