Android Auth0锁定清除缓存

Question

I'm integrating Auth0's Lock as part of the login process of my app, as to adhere with the web implementation of Auth0's login.

I followed the directions in the README.md of the Lock (Android) repository and I'm able to login with Google without issues.

The problem I'm facing is that I'm unable to indicate to Auth0 or the Lock that I have logged my user out, so I'm never again prompted to choose which account I want to login as when I re-login. I currently store my session info in SharedPreferences and my current logout procedure is to clear that data. I am able to navigate back to the UI of the login screen, but as soon as I touch on the Google icon to login via Google, Auth0 authenticates against my previously logged in user without prompting me to enter my credentials.

Is there an official way to clear the cache with Auth0's Lock?

Answer 1

I would recommend you to follow the Android Quickstart guide, more specifically, the part about session handling where it describes one possible way of maintaining a user session after login.

The last section of the session handling part is about how to achieve log out. The provided sample code is the following:

private void logout() {
  // Clear credentials (depends on how you store them in the first place)
  setUserCredentials(null);

  // Navigate to Lock login screen
  startActivity(new Intent(this, LoginActivity.class));
}

Have in mind that the setUserCredentials is specific to that particular sample, the general idea would be that you store the received tokens somewhere and then provide the user the option to log out, which triggers the cleanup of the tokens and the redirection to the login screen.
