I am using mediaRecorder to record video.
I am able to start , pause, resume and stop recording .
I want to play recorded video within same page instead of going back to SD card where it is saved.
Can Anyone help for this.
There are solutions where video is saved in sd card and playing by going SD card.
I am trying to play within app nly.
Here is Code

 public class VideoPreview : Fragment, ISurfaceHolderCallback, IOnClickListener,MediaRecorder.IOnInfoListener

    private VideoView videoView = null;

You can use the video view for this in android :

• 
  

  Add a global field like this :

  
  
  

  VideoView mVideoView; 
  
  

  
  


• 
  

  Find the reference for the same something like this:

  
  
  

  mVideoView=this.FindViewById<VideoView>(Resource.Id.mvidId); //Activity init                
  
  mVideoView=View.FindViewById<VideoView>(Resource.Id.mvidId); //Fragment init
  
  

  
  


• 
  

  Play video something like this:

  
  
  

      private void playVideo(object sender, EventArgs e)
  
  {
  
     try
  
   {
  
      mVideoView.SetVideoPath(**VideoPath**);
  
      mVideoView.SetMediaController(new MediaController(Activity));
  
      mVideoView.RequestFocus();
  
      mVideoView.Start();          
  
   }
  
   catch (IOException ex)
  
   {
  
      StopTimer();
  
      mediaRecorder.Release();          
  
   }
  
  }
  
  

  
  

 VideoView mVideoView;

private void playVideo(object sender, EventArgs e)

    {

        try

        {

            mVideoView.SetVideoPath(dir + "/rec" + videoFileName + ".mp4");

            mVideoView.SetMediaController(new MediaController(Activity));

            mVideoView.RequestFocus();

            mVideoView.Start();

            //StopTimer();

            //CreateTimer();

        }

        catch (IOException ex)

        {

            // String message = e.getMessage();

            // Log.i(null, "Problem " + message);

            StopTimer();

            mediaRecorder.Release();

            // e.printStackTrace();

        }

    }
