java - VR-Like App / Issues doubling the output -


i'm doing app testing few images (do / or not) scientific project. isolate person tested he/she vr-glasses (cardboard) person can see images , keyboard klick "good" or "bad".

due i'm a) @ stage 1 learning android developing , b) not using vr-sensors camera, acceration etc. goal create app show 2 images on 50/50 shared screen side side.

for first approach, i've used 5 images in dravable directory, , animated them animationdrawable.

i have few questions far:

to show same image 2 times side side, had use 2 animationdrawable side side - not elegant , efficient. there better way double output of one-time-happening animation?

public class gameactivity extends activity {

@override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.game);     getwindow().addflags(windowmanager.layoutparams.flag_keep_screen_on);      imageview myanimation = (imageview) findviewbyid(r.id.spin_animation);     final animationdrawable myanimationdrawable             = (animationdrawable) myanimation.getdrawable();      myanimation.post(             new runnable() {                  @override                 public void run() {                     myanimationdrawable.start();                 }             });      imageview myanimation1 = (imageview) findviewbyid(r.id.spin_animation1);     final animationdrawable myanimationdrawable1             = (animationdrawable) myanimation1.getdrawable();      myanimation1.post(             new runnable() {                  @override                 public void run() {                     myanimationdrawable1.start();                 }             }); }  @override public void onwindowfocuschanged(boolean hasfocas) {     super.onwindowfocuschanged(hasfocas);     view decorview = getwindow().getdecorview();     if (hasfocas) {         decorview.setsystemuivisibility(                 view.system_ui_flag_layout_stable                         | view.system_ui_flag_layout_hide_navigation                         | view.system_ui_flag_layout_fullscreen                         | view.system_ui_flag_hide_navigation // hide nav bar                         | view.system_ui_flag_fullscreen // hide status bar                         | view.system_ui_flag_immersive);     }   }

doing so, lot of "skipped [30-60] frames! application may doing work on main thread.". why that?

is there way randomise output of animationdrawable, or need strategy that?

best!
