title: Howto let a user change account data in 'Accounts and sync'
body: <p>There is an existing account on the phone that is used for a sync service. The account has some settings that the user entered when he created the account. Theses settings are stored as user data (--> <code>mAccountManager.addAccountExplicitly(account, mPassword, userData)</code>).</p>
  
  <p>The user should be able to change these settings. How can this be achieved? Do I need a standalone app to change existing account data?</p>
  
  <p>I guess the user would go to 'Settings'/'Accounts and sync'/'myAccount' and should find a menu entry like 'modify account data'. This menu entry should open the same activity that the user has already used to enter the data initially.</p>
  
  <p>Any hints to push me in the right direction?</p>
