java - VideoView unable to open content from internel storage -

i have following code:

try {         myvideoview.setmediacontroller(mediacontrols);         file mydir = getdir("mydir", context.mode_private);         myvideoview.setvideopath(mydir.getpath()+"/filename.3gp");     } catch (exception e) {         log.e("error", e.getmessage());         e.printstacktrace();     }      myvideoview.requestfocus();     myvideoview.setonpreparedlistener(new onpreparedlistener() {         // close progress bar , play video         public void onprepared(mediaplayer mp) {             progressdialog.dismiss();             myvideoview.seekto(position);             if (position == 0) {                 myvideoview.start();             } else {                 myvideoview.pause();             }         }     }); 

within oncreate() method. problem throws ioexception, , says unable open content. works perfect if use myvideoview.setvideouri(path/to/server) instead of myvideoview.setvideopath(path/to/local/storage). permissions @ manifest.xml fine, , not says file not found or something. says unable open it. not video format problem either, because same video when play server. if useful info, have activity in background (same app), , videoview activity in foreground. thank you!

hi use play internal video

and video view class here

public class viewvideo extends activity {   private string filename;   videoview vv;   @override   public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         system.gc();         intent = getintent();         bundle extras = i.getextras();         filename = extras.getstring("videofilename");         // vv = new videoview(getapplicationcontext());         setcontentview(r.layout.activity_main);         vv = (videoview) findviewbyid(r.id.videoview);         vv.setvideopath(filename);         vv.setmediacontroller(new mediacontroller(this));         vv.requestfocus();         vv.start();   }
