Question

I am playing an stream from Internet and because long processes such as network operation should not be handled on UI Thread, I’m using AsyncTask.
In Main Thread I set some specification of videoView:

public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.videoview);
    progressDialog = ProgressDialog.show(this, "Loading", "Please Wait", true, true);

    videoView = (VideoView) findViewById(R.id.surface_view);
    videoView.setVideoPath(ChannelPath);
    videoView.setMediaController(new MediaController(this));

    new LoadStream().execute("");
}

And in AsyncTask I start the video:

private class LoadStream extends AsyncTask<String, Void, Void> {
    protected Void doInBackground(String... urls) {
            videoView.setOnPreparedListener(new OnPreparedListener() {
                public void onPrepared(MediaPlayer mp) {
                    videoView.start();
                    progressDialog.dismiss();
                }
            });
        return null;
    }
}

I tried to have all the parts related to videoView on AsyncTask but was unable to setVideoPath and setMediaController on AsyncTask.
I am wondering which part is exactly the time consuming part? Is my code alright? or I’m still having the long process on UI Thread?

Answer 1

You donot need to use Async Task for this. Use only ProgressDialog progressBar = ProgressDialog.show(context, "", "Loading Records, Please Wait..", true); and dissmiss this progressBar in onPrepared method.
