    <p>I am trying to calculate the duration of a media file and updating the list upon retrieval. I am using <code>asyncTask</code> for calculating the duration. But app hangs for the duration till it is calculating the size. Why is it happening? Is there a better approach?</p> <p>My async task is:- ew <code>LongOperation().execute(mFileMang.getCurrentDir()+"/" + mDataSource.get(position));</code></p> <pre><code> private class LongOperation extends AsyncTask&lt;String, Void, String&gt; { @Override protected String doInBackground(String... params) { MediaPlayer mp = MediaPlayer.create(mContext, Uri.parse(params[0])); long duration = mp.getDuration(); mp.reset(); mp.release(); String finalTimerString = ""; String secondsString = ""; String minutesString = ""; // Convert total duration into time int hours = (int)( duration / (1000*60*60)); int minutes = (int)(duration % (1000*60*60)) / (1000*60); int seconds = (int) ((duration % (1000*60*60)) % (1000*60) / 1000); // Add hours if there if(hours &gt; 0){ finalTimerString = hours + ":"; } // Prepending 0 to seconds if it is one digit if(seconds &lt; 10){ secondsString = "0" + seconds; }else{ secondsString = "" + seconds;} if(minutes &lt; 10){ minutesString = "0" + minutes; }else{ minutesString = "" + minutes;} duration_video = finalTimerString = finalTimerString + minutesString + ":" + secondsString; return null; } @Override protected void onPostExecute(String result) { //might want to change "executed" for the returned string passed into onPostExecute() but that is upto you } @Override protected void onPreExecute() { } @Override protected void onProgressUpdate(Void... values) { } </code></pre> <p>}</p>

    1. COYou should step through it with a debugger or log steps so you can tell *exactly* where it's hanging. At that point it'll be more obvious what's causing it. On first glance, the code looks fine.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
