Facebook loginmanager empty email

The frustrating issue of an empty email address when trying to log in to Facebook using the Facebook LoginManager!

This issue can occur due to various reasons, including:

  1. Incorrect Facebook App ID or App Secret: Make sure you have entered the correct Facebook App ID and App Secret in your code.
  2. Facebook App not configured correctly: Ensure that your Facebook App is properly configured, including the email address and password.
  3. Email address not verified: If the email address associated with your Facebook App is not verified, you may encounter this issue.
  4. Facebook LoginManager not initialized correctly: Verify that you have initialized the Facebook LoginManager correctly in your code.

To troubleshoot this issue, you can try the following:

  1. Check the Facebook App settings: Go to the Facebook Developer Dashboard, select your App, and check the "Basic" tab. Ensure that the "Email" field is filled in and the "Email Verification" status is "Verified".
  2. Verify the Facebook LoginManager initialization: Check that you have initialized the Facebook LoginManager correctly in your code. Make sure you have called the FacebookLoginManager.getInstance() method and passed the correct App ID and App Secret.
  3. Check the email address in the Facebook LoginManager: Use the Facebook LoginManager's getLoginStatus() method to retrieve the current login status. Check the getAccessToken() method to see if it returns an empty string or null. If it does, it may indicate that the email address is not set correctly.
  4. Try logging out and logging back in: Sometimes, logging out and logging back in can resolve the issue.

Here's an example of how to initialize the Facebook LoginManager in Java:

FacebookLoginManager loginManager = FacebookLoginManager.getInstance();
loginManager.init(this, "YOUR_APP_ID", "YOUR_APP_SECRET");

And here's an example of how to get the login status and access token in Java:

FacebookLoginManager loginManager = FacebookLoginManager.getInstance();
LoginStatus status = loginManager.getLoginStatus();
String accessToken = loginManager.getAccessToken();
