我正在开发一个 android 应用程序并想集成 Twitter。
我的理解是，如果在用户的设备上安装了官方的 android Twitter 应用程序，那么我们可以使用此处提到的帐户管理器进行身份验证.. 如果未安装，则显示 twitter 登录网页。
我的理解正确吗？
现在使用 twitter 网络登录页面进行身份验证工作正常。但是如何使用帐户管理器登录？
使用 AccountsType 作为“com.twitter.android.auth.login” 我使用来自 •com.twitter.android.oauth.token •com.twitter.android.oauth.token.secret 的帐户管理器获得了令牌和令牌秘密
我正在使用 Twitter4J，并使用我的 CONSUMER_KEY 和 CONSUMER_SECRET 以及 recvd 进行身份验证。令牌。但身份验证总是失败。
CONSUMER_KEY 和 CONSUMER_SECRET 是我在 Twitter 上注册应用程序时获得的密钥……但我不明白如何将这些密钥用于官方 Android Twitter 应用程序身份验证？
请。让我知道 谢谢
这是我的代码
