When deling with access token OAuth 2.0 In a nutshell what's the difference from using: AccountManager.getAuthToken ("oauth2:https...userinfo.profile") , and using Google Plays: GoogleAuthUtil.getToken(mActivity, mEmail, mScope) As I understand it they both produce a challenge screen for the user, the Google Plays screen is user friendlier. The access token can have same scope right?! Both call have to be asynchronously. InvalidateToken looks like it has to be checked for in both calls, and more? nibarius I didn't know about using Google Play services for OAuth 2.0 authentication, but after

Android Login - Account Authenticator vs Manual Authentication

阅读更多关于 Android Login - Account Authenticator vs Manual Authentication

问题 I'm about to implement login along with user authentication in my app. My first idea was to do it manually, register username and password with the server, get auth token, save it and use it in subsequent requests. After googling around, I gathered that the correct way to do it on Android was using Account Authenticator.

阅读更多关于 Should you use AccountManager for storing Usernames and Passwords for an Android app?

问题 I would like to know if one should implement AccountManager to save user credentials such as username, email, passwords etc. I can't find a good reason to use it myself. I don't want other applications to have access to the Accounts and I don't really want them showing in the "Accounts and Sync" settings (although maybe that's not a big deal). So my question is: should I use it? Pros/cons? Can I hide the Accounts from other apps and stop them from appearing in "Accounts and Sync"? 回答1: This

阅读更多关于 AuthToken from AccountManager in Android Client No Longer Working

问题 I'm pretty exasperated. I'm attempting to build a turn-based multiplayer online game for Android using Google App Engine in Java as the server. They seem like a perfect fit. Android requires a Google account, and GAE uses a Google account for authentication, while being free and scalable. So before the holidays I was able to get authentication to my GAE app from my Android client using the new AccountManager API in Android 2.0. The following code allows you to access the AuthToken of the user

问题 setAccountAuthenticatorResult can be called from the Activity, which extends AccountAuthenticatorActivity . My activity extends that, but launches ASyncTask and hence this setAccountAuthenticatorResult should be called from ASyncTask (or, the result of ASyncTask should be passed back to the main thread).

(This would useful at the very least for development, testing, and demo purposes.) 回答1: The only solution I've found is to manually clear out the data stored in
