Android VideoView playback issues on recorded files -

-

the problem have trying program playback .amr file has been recorded using default android voice recorder. have downloaded mp3 voice recorder , tried playback on doesn't work either. have downloaded .amr , .mp3 files work it's ones recorded don't seem work.

code dump:

private static final string recording = new string(environment.getexternalstoragedirectory().getpath()) + file.separatorchar + "my documents" + file.separatorchar + "my recordings";     arraylist<string> songlist = new arraylist<string>();     private listview playlist;     private videoview videoview;     private mediacontroller mediacontroller;  private void loadplaylist()     {         songlist.clear();          file home = new file(recording);         if (home.listfiles( new amrfilter()).length > 0) {             (file file : home.listfiles(new amrfilter())) {                 songlist.add(file.getname());             }         }          if (home.listfiles( new mp3filter()).length > 0) {             (file file : home.listfiles(new mp3filter())) {                 songlist.add(file.getname());             }         }          arrayadapter<string> adapter = new arrayadapter<string>(this, android.r.layout.simple_list_item_1, songlist);         playlist.setadapter(adapter);     }  class amrfilter implements filenamefilter {          public boolean accept(file dir, string name) {             // todo auto-generated method stub             return (name.endswith(".amr"));          }            }      private void refreshplaylist()     {         songlist.clear();          file home = new file(sd_path);         if (home.listfiles( new mp3filter()).length > 0) {             (file file : home.listfiles(new mp3filter())) {                 songlist.add(file.getname());             }         }         arrayadapter<string> adapter = new arrayadapter<string>(this, android.r.layout.simple_list_item_1, songlist);         playlist.setadapter(adapter);     }  private void playfile(string currentfile) throws illegalargumentexception, securityexception, illegalstateexception, ioexception {         videoview.setvideopath(currentfile);         videoview.start();         playbtn.setvisibility(view.visible);          // set progress max         videoview.setonpreparedlistener(new mediaplayer.onpreparedlistener() {             @override             public void onprepared(mediaplayer mp) {                 playbar.setmax(videoview.getduration());                 startseekbar.setmax(videoview.getduration());                 startseekbar.setprogress(videoview.getcurrentposition());                 stopseekbar.setmax(videoview.getduration());                 stopseekbar.setprogress(videoview.getduration());                 int msec = videoview.getduration();                 int time[] = secondstominutes(msec);                 totalplaytime.settext(time[0] + ":" + time[1] + ":" + time[2]);             }         });          handler.postdelayed(runner, 1000);     }

the logcat error is:

07-01 05:51:45.363: e/mediaplayer(2912): error (1, -2147483648) 07-01 05:51:45.383: e/mediaplayer(2912): error (1,-2147483648) 07-01 05:51:45.383: d/videoview(2912): error: 1,-2147483648

i'm not sure problem restricted ones record. don't think it's file permissions android mp3 player can play mp3 recording.

<uses-permission android:name="android.permission.write_external_storage" />     <uses-permission android:name="android.permission.read_external_storage" />      <uses-sdk         android:minsdkversion="8"         android:targetsdkversion="17" />      <application         android:allowbackup="true"         android:icon="@drawable/ic_launcher"         android:label="@string/app_name"         android:theme="@style/apptheme" >         <activity             android:name="com.jahed.medialooper.mainactivity"             android:label="@string/app_name" >             <intent-filter>                 <action android:name="android.intent.action.main" />                  <category android:name="android.intent.category.launcher" />             </intent-filter>         </activity>     </application>

playing sound file in video view not great idea. videoview play video files can play .mp4 .3gp ease

try using mediaplayer

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
