    <p>I'm developing a small application so I can get more experience of Android development. I wrote a method that list all of contact number and total messages (just like GoSMS or default SMS Application). But problem that I'm facing right now is slow performance. Below is what I have done to get the result.</p> <p>Sample result: Mr AAA (10000)</p> <p>Steps:</p> <ol> <li>Get all SMS thread ID</li> <li>Loop and get total messages belong to each thread ID.</li> <li>Get the contact number belong to that thread.</li> <li>Use that number and PhoneLookup to get contact name.</li> </ol> <p>Here is the method:</p> <pre><code>public void populateContactList() { // Get all sms threads Cursor smsAddressCursor = getContentResolver().query( SMSCVar.CONTENT_URI, new String[] { "DISTINCT "+SMSCVar.THREAD_ID}, null, null, null); while(smsAddressCursor.moveToNext()) { Contact c = new Contact(); // Get thread_id String thread_id = smsAddressCursor.getString(smsAddressCursor.getColumnIndex(SMSCVar.THREAD_ID)); // Get total messages Cursor totalMessage = getContentResolver().query( SMSCVar.CONTENT_URI, new String[] {"count("+SMSCVar.BODY+")"}, SMSCVar.THREAD_ID+" = ?", new String[] {thread_id}, null); totalMessage.moveToNext(); c.setNumberOfSMS(totalMessage.getInt(0)); totalMessage.close(); // Get number Cursor number = getContentResolver().query( SMSCVar.CONTENT_URI, new String[] {SMSCVar.ADDRESS}, SMSCVar.THREAD_ID+" = ?", new String[] {thread_id}, null); number.moveToNext(); String pNumber = number.getString(0); number.close(); // Get contact name Uri uriPhonenumber = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI , Uri.encode(pNumber)); Cursor contactDisplayName = getContentResolver().query( uriPhonenumber, new String[] {ContactsContract.PhoneLookup.DISPLAY_NAME}, null, null, null); // If cursor is not null and has at least one result if(!contactDisplayName.isNull(0) &amp;&amp; contactDisplayName.getCount() &gt; 0) { // Get contact name for display contactDisplayName.moveToNext(); c.setContactName(contactDisplayName .getString(contactDisplayName .getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME))); } else { // Get contact number for display c.setContactName(pNumber); } // Don't get confuse here, setContactNumber method is not used for display purpose. c.setContactNumber(pNumber); contactListAdapter.add(c); contactDisplayName.close(); } smsAddressCursor.close(); } </code></pre> <p>I've coded to close cursor properly but I still get GARBAGE COLLECTOR messages and slow retrieving time (5 seconds). My SMS is over 11000 messages.</p> <p>So please assist me! </p> <p>Thank you!</p> <p>P/S: I'm not an English native speaker so I've tried my best to make my question easy to understand. </p>

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.
