I'm using your code from Corporate Addressbook to try to get a list of mails from my gmail account. But I'm stuck, this is what I'm doing:
1. Sending FolderSync request:
<code>
String uri = mUri + "FolderSync";
String xml = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
+ "<FolderSync xmlns=\"FolderHierarchy:\">\n" +
"\t<SyncKey>0</SyncKey>\n"
+ "</FolderSync>";
</code>
2. This is the response I get back. So far so good
<code>
<?xml version="1.0" encoding="utf-8" ?>
<FolderSync xmlns="FolderHierarchy">
  <Status>1</Status>
  <SyncKey>1311783116298</SyncKey>
  <Changes>
    <Count>14</Count>
    ...
    <Add>
      <ServerId>Mail:^sync_gmail_group</ServerId>
      <ParentId>0</ParentId>
      <DisplayName>[Gmail]</DisplayName>
      <Type>12</Type>
    </Add>
    <Add>
      <ServerId>Mail:DEFAULT</ServerId>
      <ParentId>0</ParentId>
      <DisplayName>Inbox</DisplayName>
      <Type>2</Type>
    </Add>
    ...
  </Changes>
</FolderSync>
</code>
3. Now I take the ServerId for Inbox (Mail:DEFAULT) and do a Search Request
<code>
String uri = mUri + "Search";
String xml = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" +
"<Search xmlns=\"Search:\" xmlns:airsync=\"AirSync:\"  xmlns:email=\"Email:\" xmlns:contacts=\"Contacts:\" >\n" +
"<Store>\n" +
"<Name>Mailbox</Name>\n" +
"<Query>\n" +
"<And>\n" +
"<airsync:CollectionId>Mail:DEFAULT</airsync:CollectionId>\n" +
"<FreeText>mail</FreeText>\n" +
"</And>\n" +
"</Query>\n" +
"</Store>\n" +
"</Search>";
</code>
4. Here is where I get stuck. I get no e-mails in the response just a status 3 error.
<code>
<?xml version="1.0" encoding="utf-8" ?>
<Search xmlns="Search">
<Status>3</Status>
</Search>
</code>
Could you please help me. Thanks
