Google Play Services - granting Oauth2 permission

Question

Can you get the user to Authorize Oauth Permission(display the dialog) before a request is made? I would like to ask my users to grant permissions when they first use the app. The only way I know is to catch the UserRecoverableAuthException and launch the intent from there.

您可以致电http://developer.android.com/reference/com/google/android/gms/auth/GoogleAuthUtil.html#getToken(android.content.Context，java.lang.String，java.lang 。字符串）在您的应用首次启动时启动，如果用户已经同意，它将返回一个有效的令牌，或者抛出UserRecoverableAuthException，在这种情况下，您应该将用户定向到其中包含的意图。
