You cant get Email id from Facebook Login....why???

If your Facebook account registered using "Mobile Number", and you do not have Email in same account.

Check this scenario. This might be happening, We cant blame for it to FBSDK.

Hope this will clear some points.

React Native FBSDK Login - Login with app fails

I fixed it.

The issue is in The AppDelegate.m. The file can only have one method for openUrl. It was two of them now, so I had to merge them. This worked:

- (BOOL)application:(UIApplication *)application
        openURL:(NSURL *)url
        sourceApplication:(NSString *)sourceApplication
        annotation:(id)annotation {

        BOOL handledFB = [[FBSDKApplicationDelegate sharedInstance] application:application
                             openURL:url
                             sourceApplication:sourceApplication
                             annotation:annotation
                ];

        BOOL handledRCT = [RCTLinkingManager application:application openURL:url sourceApplication:sourceApplication annotation:annotation];

        return handledFB || handledRCT;
}

Facebook SDK & custom button Login in react-native 0.60+ not working

You must add libRTCFBSDK.a file in the Link binary with Libraries . To fix the 'FBSDKShareKit.h isn't found' issue change ~/Documents/FacebookSDK to $(HOME)/Documents/FacebookSDK

Android facebook login not working with installed Facebook app

Check out the bottom of step 4: https://developers.facebook.com/docs/getting-started/facebook-sdk-for-android/3.0/

If you have not entered your app key hash properly, Facebook login via the WebView popup (if the app is not installed) will still work, but login via the native Facebook app won't.

You should see this exception in LogCat:

com.facebook.http.protocol.ApiException: remote_app_id does not match stored id

The Facebook SDK prints its exceptions so check there anyway if there are other problems.

Facebook SDK 4 for Android - how to log out programmatically

You can use LoginManager.getInstance().logOut();, even if you use LoginButton because

This UI element wraps functionality available in the LoginManager.

EDIT:
Just to mention that this works for Facebook SDK v4. I don't know if they will change it in the future.

@as batoutofhell mention, don't forget to put FacebookSdk.sdkInitialize(getApplicationContext()); to initialize the facebook sdk. Please see here for the details.
