accounts

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: <service android:name="AccountAuthenticatorService" android:exported="true" android:process=":auth"> <intent-filter> <action android:name=

I know that in the end it, can't be done. But, what are the options to: a) limit the options for persons to create multiple accounts, b) increase the chance of detecting multiple accounts / person for a blog-like web service? (people can sign up for their own blog) Update: I think the 'limit the options' has been answered nicely. (there is no reliable method, but we can raise the bar) However, I would still like to know what other options there are to detect multiple accounts? I'm assuming you're talking about a free service? I can't think of any ways that don't either have serious drawbacks
