is normal?

button resize

public void clickresize(view view) {     setrequestedorientation(activityinfo.screen_orientation_portrait); } 

button fullscreen

public void clickfullscreen(view view) {     setrequestedorientation(activityinfo.screen_orientation_landscape); } 

methods addflags, clearflags , configurationchanged()

private void onfullscreen() {         window.addflags(windowmanager.layoutparams.flag_fullscreen);         window.clearflags(windowmanager.layoutparams.flag_force_not_fullscreen);     }  private void offfullscreen() {     window.addflags(windowmanager.layoutparams.flag_force_not_fullscreen);     window.clearflags(windowmanager.layoutparams.flag_fullscreen); }  public void onconfigurationchanged(configuration newconfig) {     super.onconfigurationchanged(newconfig);      if (newconfig.orientation == configuration.orientation_landscape) {         onfullscreen(); }                    } else if (newconfig.orientation == configuration.orientation_portrait) {             offfullscreen();     }        } 

i have faced same problem , resolved follows :

set setrequestedorientation(activityinfo.screen_orientation_unspecified) after rotation code:

from :

public void clickresize(view view) { setrequestedorientation(activityinfo.screen_orientation_portrait);} 

to :

public void clickresize(view view) { setrequestedorientation(activityinfo.screen_orientation_portrait); setrequestedorientation(activityinfo.screen_orientation_unspecified)}
