如何在共享首选项中存储来自OAuth2的凭据 [英] How store credential from OAuth2 in shared preferences

问题描述

我有一些与Google相关的活动，我只想连接一次Google并在整个应用程序中共享证书.我有一个通过OAuth2向Google进行身份验证的活动.它返回一个凭证，如下所示:

I have several activities that connect to Google, I only want to connect to Google once and share the credential throughout the app. I have an activity that authenticates to Google via OAuth2. It returns a credential as follows:

private GoogleAccountCredential credential;

...

credential = GoogleAccountCredential.usingOAuth2(this, DriveScopes.DRIVE);

是否可以将其放入共享首选项"中.我已经尝试了所有明显的类型，例如可包裹的等，并且发现凭证可以放入共享首选项"，但是找不到将其转换回GoogleAccountCredential的吸气剂.我什至尝试将其设为对象，但是getter再次将其转换回GoogleAccountCredential类型的问题.

Is there a way to put it into Shared Preferences. I've tried all the obvious types, i.e. parcelable, etc. and I've found the credential can be put into Shared Preferences, but can't find a getter to convert it back to GoogleAccountCredential. I had even tried making it an object, but again issues with the getter converting it back to the GoogleAccountCredential type.

如果共享首选项"不起作用，还有其他选择吗?

If Share Preference isn't capable, it there an alternative?

提前感谢您的时间和帮助.

Thanks in advance for you time and help.
