Answer 1

I would suggest looking at the AsyncTask documentation, this seems ideally suited for doing video pre-loading. This will allow you to keep your UI thread stable during loading. There is an example of using the AsyncTask method here.

To add a progress dialog:

• Create a private ProgressDialog object as part of an extension class of AsyncTask.
• In the onPreExecute() method you can perform progress dialog setting up, such as: pd.setMessage(...) pd.setTitle(...) pd.show(...)
• In the onPostExecute(...) method, dismiss the dialog: pd.dismiss();

Additionally, you can update the progress dialog using its incrementProgressBy(...) method, or alternately have a looping animation using the setIndeterminate(...) method. Giving the user feedback of the loaded progress is a good idea in UI design :)

I hope this helps!

First, declare the progress dialog

private static ProgressDialog progressDialog;

Then, in onCreate, before calling runOnUiThread, start the dialog

progressDialog = ProgressDialog.show(this, "", "Loading...", true);

In playVideo, set a OnPreparedListener that will dismiss the dialog when the video is ready to play

mVideoView.setOnPreparedListener(new OnPreparedListener() {

    public void onPrepared(MediaPlayer arg0) {
        progressDialog.dismiss();
        mVideoView.start();
    }
});

IMHO in this case it's more graceful to use ProgressBar widget insted of Progress dialog. It looks better on the video surface. You could add the progress bar to your activity's layout above the VideoView:

<ProgressBar 
    android:id="@+id/progress" 
    android:indeterminate="true" 
    android:indeterminateBehavior="repeat" 
    android:layout_width="100dp" 
    android:layout_height="100dp" 
    android:layout_gravity="center">
</ProgressBar>

In onCreate, before calling runOnUiThread, show the progress:

mProgress = (ProgressBar)findViewById(R.id.progress);
mProgress.setVisibility( View.VISIBLE );

In onPrepared callback hide the progress:

mProgress.setVisibility( View.INVISIBLE );
