Question

Reading android.os.Build.VERSION.SDK_INT I need fix orientation of my app. So, if version < 3 I need fix orientation to portrait.
Using this code does not run.

@Override
    public void onCreate(Bundle savedInstanceState){ 
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

Answer 1

if (android.os.Build.VERSION.SDK_INT<=3) 
 {
 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); Or setRequestedOrientation(1); //1=ActivityInfo.SCREEN_ORIENTATION_PORTRAIT
 }
else
 {
 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR); or setRequestedOrientation(4); 4=ActivityInfo.SCREEN_ORIENTATION_SENSOR
 }
