I am implementing a syncadapter for an android app and would like to make the settings for the account available under the "Accounts & sync" menu. I have seen this done in the DropBox app(as shown below), but I have not been able to find documentation on how to do this. I have the accounted added, just want to add a link to the account settings in this menu.

In your Android Manifest, you should have a section like this to define your account authenticator:
The meta-data tag above should point to an XML file that defines your account, like this:
The android:accountPreferences attribute above points to an XML file that defines your preferences screen, like so:
The above PreferenceScreen will launch an intent to display a settings screen, but you can also define the settings directly in the XML file.
