here code:

[activity (nohistory = true, mainlauncher = true)] public class introview : fragmentactivity {     private viewpager _viewpager;     private controleexibicaointro _controleexibicaointro;      protected override void oncreate(bundle bundle)     {         base.oncreate(bundle);          _controleexibicaointro = new controleexibicaointro(this);          if (!_controleexibicaointro.deveexibirintro())         {             fechaapresentacao();         }          setcontentview(resource.layout.introview);          _viewpager = findviewbyid<viewpager>(resource.id.viewpager);         _viewpager.adapter = new introadapter(supportfragmentmanager);          _viewpager.addonpagechangelistener(new introindicator(this.window));         _viewpager.setpagetransformer(false, new intropagetransformer());         actionbar.hide();          var btnnext = findviewbyid<button>(resource.id.btnnext);         btnnext.click += btnnext_click;          var btnskip = findviewbyid<button>(resource.id.btnskip);         btnskip.click += btnskip_click;     }      private void btnskip_click(object sender, eventargs e)     {         fechaapresentacao();     }      private void btnnext_click(object sender, system.eventargs e)     {         if (_viewpager.currentitem == (_viewpager.adapter.count - 1))         {             fechaapresentacao();         }         else         {             _viewpager.currentitem++;         }      }      private void fechaapresentacao()     {         //_controleexibicaointro.cancelaexibicaointro();          var intent = new intent(this, typeof(settingsview));         overridependingtransition(0, 0);          startactivity(intent);         overridependingtransition(0, 0);          finish();     } } 

fechaapresentacao() method use close intro activity , redirect other activity.

try adding after call finish() or second option close activities other 1 starting.

private void fechaapresentacao(){     //_controleexibicaointro.cancelaexibicaointro();     var intent = new intent(this, typeof(settingsview));     startactivity(intent);     finish();     overridependingtransition(0, 0); }   private void fechaapresentacao(){     //_controleexibicaointro.cancelaexibicaointro();     var intent = new intent(this, typeof(settingsview));     intent.setflags(intent.flag_activity_clear_top);     startactivity(intent);     overridependingtransition(0, 0); }
