Screen orientation lock

by

Here is my solution it works on phones and tablets in any Android SDK.

switch (getResources().getConfiguration().orientation){
        case Configuration.ORIENTATION_PORTRAIT:
            if(android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.FROYO){
                setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
            } else {
                int rotation = getWindowManager().getDefaultDisplay().getRotation();
                if(rotation == android.view.Surface.ROTATION_90|| rotation == android.view.Surface.ROTATION_180){
                    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT);
                } else {
                    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
                }
            }   
        break;

        case Configuration.ORIENTATION_LANDSCAPE:
            if(android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.FROYO){
                setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
            } else {
                int rotation = getWindowManager().getDefaultDisplay().getRotation();
                if(rotation == android.view.Surface.ROTATION_0 || rotation == android.view.Surface.ROTATION_90){
                    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
                } else {
                    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE);
                }
            }
        break;
    }
