android - onConfigurationChanged not called for second time -


i using following code change activity orientation while user rotates device. works fine first time, not called again. please correct me.

@override     public void onconfigurationchanged(configuration newconfig) {         super.onconfigurationchanged(newconfig);                     log.d("activity","changing orientation"); //no i18n         if (newconfig.orientation == configuration.orientation_portrait) {             log.d(tag, "orientation changed portrait"); // no i18n             setrequestedorientation(configuration.orientation_portrait);         } else if (newconfig.orientation == configuration.orientation_landscape) {             log.d(tag, "orientation changed landscape"); // no i18n             setrequestedorientation(configuration.orientation_landscape);         }     }  @override     protected void onrestoreinstancestate(bundle savedinstancestate) {         log.d("activity","on restore instancestate");   //no i18n         super.onrestoreinstancestate(savedinstancestate);     }      @override     protected void onsaveinstancestate(bundle outstate) {         log.d("activity","on save instancestate");  //no i18n         super.onsaveinstancestate(outstate);     }

after use setrequestedorientation(...); no longer have privilege of getting rotation notifications.
if want perform special actions when rotations occur, may want use orientationeventlistener

edit:
caution: code takes portrait 80-90 deg , >= 320, can changed.
may need run setrequestedorientation on ui thread if piece of code isn't running there already.

you should this: 

morientationlistener = new orientationeventlistener(this, sensormanager.sensor_delay_ui) {  @override     public void onorientationchanged(int rotation) {         boolean changed = false;          if (((rotation >= 0) && (rotation <= 80)) || (rotation >= 320)) {                         setrequestedorientation(configuration.orientation_portrait);         } else {                         setrequestedorientation(configuration.orientation_landscape);         }     } }; morientationlistener.enable();
