    <p>I am trying to produce a progress bar to tell me the percentage of the file that I have downloaded so far. The progress bar is displaying, but it does not ever update, it stays static.</p> <pre><code>while((line = reader.readLine()) != null) { values.add(line); } dialog = new ProgressDialog(ourContext); dialog.setCancelable(true); dialog.setMessage("File downloading..."); dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); dialog.setProgress(0); dialog.setMax(values.size()); dialog.show(); progressBarStatus = 0; fileSize = 0; new Thread(new Runnable() { @Override public void run() { // TODO Auto-generated method stub while(progressBarStatus &lt; values.size()){ for(int i = 0; i &lt; values.size();i++){ String[] data = values.get(i).split(","); //Log.d("Test drive " ,data[1] ); String[] dateSplit = data[1].split("[-]"); String month = dateSplit[1]; String day = dateSplit[0]; String year = dateSplit[2]; Calendar cal = Calendar.getInstance(); try { cal.setTime(new SimpleDateFormat("MMM").parse(month)); } catch (ParseException e) { // TODO Auto-generated catch block String error = e.toString(); Dialog d = new Dialog(ourContext); d.setTitle("Error"); TextView tv = new TextView(ourContext); tv.setText(error); d.setContentView(tv); d.show(); } int monthInt = cal.get(Calendar.MONTH) + 1; int yearInt = Integer.parseInt(year); int dayInt = Integer.parseInt(day); try { cashPotEntry(dayInt, monthInt, yearInt, data[3], data[2], data[4]); progressBarStatus++; Log.d("progress bar" ,progressBarStatus + " " ); Thread.sleep(1000); } catch (Exception e) { // TODO Auto-generated catch block String error = e.toString(); Dialog d = new Dialog(ourContext); d.setTitle("Error"); TextView tv = new TextView(ourContext); tv.setText(error); d.setContentView(tv); d.show(); } } progressBarHandler.post(new Runnable() { @Override public void run() { // TODO Auto-generated method stub dialog.setProgress(progressBarStatus); } }); } if(progressBarStatus &gt;= values.size()){ try { Thread.sleep(2000); } catch (InterruptedException e) { // TODO Auto-generated catch block String error = e.toString(); Dialog d = new Dialog(ourContext); d.setTitle("Error"); TextView tv = new TextView(ourContext); tv.setText(error); d.setContentView(tv); d.show(); } dialog.dismiss(); } } }).start(); } </code></pre>

    1. COWhat is `progressBarHandler`? And why are you posting that? I don't think that makes any sense. Why not just simply call `setProgress()`?

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
