アンドロイドでビデオを再生する

Question

アンドロイドには完全に新しいビデオ再生を実装しています。これはこれまでに集めたコードです。

ロジックに応じてビデオを再生する必要があります。どこが間違っているのか分かりません。

     //Get the file path for external storage 
     String a = Environment.getExternalStorageDirectory().getAbsolutePath(); 
     final String finalPath = a+"/Videos"; 
     //Define new file function 
     File f=new File(finalPath); 

     if(f.isDirectory()){

      setListAdapter(new ArrayAdapter<String>(this, R.layout.listview,files)); 
      //Define listview 
      ListView listview = getListView(); 
      listview.setTextFilterEnabled(true); 

      //Onclick list item event

        //get selected items

        Uri uri = Uri.parse(finalPath); 

        MediaController mediaController = new MediaController(getBaseContext()); 
        mediaController.setAnchorView(mVideoView); 

        Uri video = Uri.parse(finalPath+"/"+selectedValue);

<VideoView 
    android:id="@+id/videoView1" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    /> 


VideoView vv = (VideoView) findViewById(R.id.videoView1); 
uri = "your video uri"; 
vv.setVideoURI(Uri.parse(uri)); 
vv.start(); 

vv.setOnCompletionListener(new OnCompletionListener() { 
    @Override 
    public void onCompletion(MediaPlayer mp) { 
      finish(); 
    } 
});
