    <p>I am having a problem accessing the arraylists populated by this <code>asynctask</code> from class file <code>A</code>. From Class file <code>B</code> I try to use A a method such as</p> <p><code>inStream = new InboxLoader(MainInbox.this,1); Log.e("JJJ",""+inStream.getMemId().size());</code> </p> <p>method from a different class file I get a crash in logcat saying <code>indexoutofbounds error</code> I was looking for an alternative to having this <code>AsyncTask</code> in the same file as class <code>B</code> public class InboxLoader { Context ctx; ArrayListmemName,memAvatar,msgBody,msgTime; ArrayList msgId,memId;</p> <pre><code>InboxLoader(Context context,int id){ this.ctx = context; this.msgBody = new ArrayList&lt;String&gt;(); this.memAvatar = new ArrayList&lt;String&gt;(); this.memId = new ArrayList&lt;Integer&gt;(); this.memName = new ArrayList&lt;String&gt;(); this.msgTime = new ArrayList&lt;String&gt;(); this.msgId = new ArrayList&lt;Integer&gt;(); new LoadStream().execute(id); } public ArrayList&lt;String&gt; getMsgBody(){ return msgBody; } public ArrayList&lt;String&gt; getMemAvatar(){ return memAvatar; } public ArrayList&lt;Integer&gt; getMemId(){ return memId; } public ArrayList&lt;String&gt; getMemName(){ return memName; } public ArrayList&lt;Integer&gt; getMsgId(){ return msgId; } public ArrayList&lt;String&gt; getMsgTime(){ return msgTime; } /* * STARTS GRABBING DATA FOR THE LISTVIEW */ public class LoadStream extends AsyncTask&lt;Integer, Integer, JSONObject&gt; { ProgressDialog progressBar; @Override protected void onPreExecute() { progressBar = new ProgressDialog(ctx, ProgressDialog.STYLE_SPINNER); progressBar.setMessage("Generating Inbox...."); progressBar.show(); super.onPreExecute(); } @Override protected JSONObject doInBackground(Integer... params) { List&lt;NameValuePair&gt; params2 = new ArrayList&lt;NameValuePair&gt;(); params2.add(new BasicNameValuePair("memberId", String.valueOf(1))); params2.add(new BasicNameValuePair("type", "get")); JSONObject json = new jsonParser().makeRequest("url", params2); return json; } @Override protected void onPostExecute(JSONObject json) { super.onPostExecute(json); int success = 0; JSONObject jData; JSONArray jObj = null; try{ // successfully received details jObj = json.getJSONArray("details"); // JSON Array success = json.getInt("success"); }catch(Exception e){ e.printStackTrace(); } if(success == 1){ try{ for( int i = 0; i &lt; jObj.length(); i++ ){ //GET OBJECT FROM JSON Array jData = jObj.getJSONObject(i); //ASSIGN VALUES msgId.add(jData.getInt("msg_id")); memAvatar.add(jData.getString("mem_avatar")); memName.add(jData.getString("mem_name")); memId.add(jData.getInt("mem_id")); msgBody.add(jData.getString("msg_body")); msgTime.add(jData.getString("msg_time")); } }catch(Exception e){ Log.e("STREAM FILE PROBLEM", e.getMessage()); } } progressBar.dismiss(); Log.e("STREAM FILE PROBLEM",""+memId.size());//prints 1 } } } </code></pre>

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.
