I am using <code>AsyncTask</code> to do background processing i.e I'm fetching the data from the server and storing in the <code>List</code> in <code>doInBackground()</code> method. I'm using this stored data in <code>onPostExecute()</code>. The problem that I'm facing is the <code>onPostExceute()</code> is getting executed even before <code>doInBackground()</code> is done it's execution. Can someone suggest what might be going wrong ? Code: <pre><code>AsyncTask<Void, Void, Void> read= new AsyncTask<Void, Void, Void>() { ProgressDialog progress= new ProgressDialog(LastData.this); ArrayList<String> testData; DBAdapter db; @Override protected void onPreExecute() { // TODO Auto-generated method stub super.onPreExecute(); progress.setTitle("Please Wait"); testData= new ArrayList<String>(); db= new DBAdapter(LastData.this); progress.setProgressStyle(ProgressDialog.STYLE_SPINNER); progress.setMessage("Fetching Data !!"); progress.show(); } @Override protected Void doInBackground(Void... params) { // TODO Auto-generated method stub ParseQuery query = new ParseQuery("Details"); query.findInBackground(new FindCallback() { public void done(List<ParseObject> dataList, ParseException e) { if (e == null) { Log.d("Details", "Retrieved " + dataList.size() + " scores"); for (int idx = 0; idx < dataList.size(); idx++) { data.add(dataList.get(idx).get("fname") .toString()); } } else { System.out.println(e.getMessage()); } for (int idx = 0; idx < data.size(); idx++) { testData.add(data.get(idx)); } System.out.println("size inside is " + testData.size()); } }); return null; } @Override protected void onPostExecute(Void result) { // TODO Auto-generated method stub super.onPostExecute(result); progress.dismiss(); Toast.makeText(LastData.this, "Size is "+testData.size(), Toast.LENGTH_LONG).show(); } }; read.execute(); </code></pre> <code>Toast</code> meassage in <code>onPostExecute()</code> is getting displayed even before the <code>doInBackground</code> method is exceuted.

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.
