media player - android ANR in MediaPlayer reset -

i've got simple activity plays video through videoview

public class avideo extends activity { private videoview mvideoview; private mediacontroller mc;  @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.a_video);     bundle extras = getintent().getextras();     uri path = uri.parse(extras.getstring("videouri"));     mvideoview = (videoview) findviewbyid(r.id.video);     mvideoview.setvideouri(path);     mc = new mediacontroller(this);     mvideoview.setmediacontroller(mc); }  @override protected void onresume() {     super.onresume();     mvideoview.start();     mc.show(); } } 

in cases when user pushes button, on activity, before video starts playing, he's got anr. here's traces:

dalvik threads: "main" prio=5 tid=3 native | group="main" scount=1 dscount=0 s=n obj=0x4001b268 self=0xbd00 | systid=423 nice=0 sched=0/0 cgrp=default handle=-1344001384 @ android.media.mediaplayer._reset(native method) @ android.media.mediaplayer.reset(mediaplayer.java:1028) @ android.widget.videoview.release(videoview.java:476) @ android.widget.videoview.access$2100(videoview.java:49) @ android.widget.videoview$6.surfacedestroyed(videoview.java:467) @ android.view.surfaceview.reportsurfacedestroyed(surfaceview.java:488) @ android.view.surfaceview.updatewindow(surfaceview.java:413) @ android.view.surfaceview.onwindowvisibilitychanged(surfaceview.java:189) @ android.view.view.dispatchwindowvisibilitychanged(view.java:3782) @ android.view.viewgroup.dispatchwindowvisibilitychanged(viewgroup.java:692) @ android.view.viewgroup.dispatchwindowvisibilitychanged(viewgroup.java:692) @ android.view.viewgroup.dispatchwindowvisibilitychanged(viewgroup.java:692) @ android.view.viewroot.performtraversals(viewroot.java:706) @ android.view.viewroot.handlemessage(viewroot.java:1633) @ android.os.handler.dispatchmessage(handler.java:99) @ android.os.looper.loop(looper.java:123) @ android.app.activitythread.main(activitythread.java:4363) @ java.lang.reflect.method.invokenative(native method) @ java.lang.reflect.method.invoke(method.java:521) @ com.android.internal.os.zygoteinit$methodandargscaller.run(zygoteinit.java:860) @ com.android.internal.os.zygoteinit.main(zygoteinit.java:618) @ dalvik.system.nativestart.main(native method) 

also logcat shows this:

i find this question , this bug, there no solution.

if getting anr message, means applicaction insufficiently responsive period of time, use runonuithread run specified action on ui thread or asynctask

    public class avideo extends activity {     private videoview mvideoview;     private mediacontroller mc;      @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.a_video);         bundle extras = getintent().getextras();         uri path = uri.parse(extras.getstring("videouri"));         mvideoview = (videoview) findviewbyid(r.id.video);          runonuithread(new runnable() {                     @override                     public void run() {                                              mvideoview.setvideouri(path);                     }                 });          mc = new mediacontroller(this);         mvideoview.setmediacontroller(mc);     }      @override     protected void onresume() {         super.onresume();         mvideoview.start();         mc.show();     }   } 

try implementing setonpreparedlistener start video.

    mvideoview.setoncompletionlistener(new oncompletionlistener() {                          @override         public void oncompletion(mediaplayer mp) {             log.i("video", "oncompletion");                          }     });     mvideoview.setonpreparedlistener(new onpreparedlistener() {                      @override         public void onprepared(mediaplayer mp) {             log.i("video", "onprepared");               if(mvideoview.canseekforward()) mvideoview.seekto(mvideoview.getduration()/5);                mvideoview.start();                            }     });     mvideoview.setkeepscreenon(true);
