    <p>Following is simple method that connects to web service and receives the XML response from server which is about 2.3MB and I'm getting <strong><code>OutOfMemoryError</code></strong> (<a href="https://stackoverflow.com/questions/6926620/soap-very-large-xml-response-outofmemoryerror">I've referred this</a>) but not being able to find my way, stuck badly </p> <pre><code>public synchronized String getUpdates(boolean news) throws Exception { String response = null; HttpPost httppost; DefaultHttpClient httpclient; ResponseHandler &lt;String&gt; res=new BasicResponseHandler(); List&lt;NameValuePair&gt; nameValuePairs; httppost = new HttpPost(context.getString(R.string.SYNCURL)); HttpParams params = new BasicHttpParams(); HttpProtocolParams.setContentCharset(params, "UTF-8"); String lastupdate = null; SharedPreferences preferences = context.getSharedPreferences(context.getPackageName(), Context.MODE_PRIVATE); lastupdate = preferences.getString(LAST_UPDATE, DatabaseHelper.updateDate); if(news) lastupdate = preferences.getString(LAST_UPDATE_NEWS, lastupdate); httpclient = new DefaultHttpClient(params); nameValuePairs = new ArrayList&lt;NameValuePair&gt;(2); nameValuePairs.add(new BasicNameValuePair("reqDTTM", lastupdate)); if(news)nameValuePairs.add(new BasicNameValuePair("doAction", "news")); if(!preferences.getString(LAST_UPDATE, "").equalsIgnoreCase(DatabaseHelper.updateDate)) { String timezon = UDFHelper.getTimeZon(context); nameValuePairs.add(new BasicNameValuePair("tz", timezon)); } httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); response = httpclient.execute(httppost, res); return response; } </code></pre> <p>Here it causes problem trying to retrieve large text in <code>String response</code> :</p> <blockquote> <p>response = httpclient.execute(httppost, res);</p> </blockquote> <p>I'm storing the response in String. Is that a problem? What is alternative solution of that?</p> <p>Here is LogCat</p> <pre><code>09-23 10:07:31.654: INFO/ActivityManager(59): Displayed activity uk.co.dodec.rcgpapp/.SplashScreen: 1267 ms (total 1267 ms)

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.
