How to get duration of Audio Stream and continue audio streaming from any point

Question

Description:

I have following code for an Audio player. I can continue Audio playback from any duration by clicking on Progress Bar(between 0-to-mediapl

Answer 1

First big problem is your order of initialization: you call getDuration before you actually call setDataSource in resetAndStartPlayer. How is MediaPlayer supposed to know duration without data source?

Here's how to do that properly:

1. call MediaPlayer.setDataSource() in Activity.onCreate

2. execute AsyncTask, in its doInBackground call MediaPlayer.prepare(), this will take a while if it's streaming from http, but after it finishes, player should know lenght of media

3. in the AsyncTask.onPostExecute call MediaPlayer.getDuration(), which should succeed if stream was opened successfully; afterwards you may call MediaPlayer.start()

Important things:

• getDuration works after prepare was called
• prepare may take longer time, and should be called in other thread
• you may also use prepareAsync and avoid AsyncTask, then you'd use setOnPreparedListener callback to call getDuration
