If you are not loading the javascript sdk async, you could see this error a lot. refer to: https://developers.facebook.com/docs/javascript/quickstart in addition, if you are using any Facebook plugins via the iframe code, be sure the src url protocol matches. <div id=”fb-root”></div> <script> window.fbAsyncInit = function() { // init the FB JS SDK FB.init({ appId : … Read more
You don’t need to push the user’s ID via ajax. You should, on the server side, use the fbsr_{app_id} cookie which holds the signed_request. Parse this signed_request using your ‘secret’ app_secret issued by FB to get the ‘user_id’. NOTE: a successful parse also shows that the cookie data provided by FB is not tampered with. … Read more
Facebook’s latest update includes a new “Account Linking” functionality that appears to solve this issue. See https://developers.facebook.com/docs/messenger-platform/account-linking
You are calling FB.getLoginStatus before the SDK is loaded and/or initialized. To wait for that, that’s what the fbAsyncInit event is for. So put the method call in there.
The answer is to go over the FBLoginView subviews, find the button and the label and customize them.

In myapp-Info.plist, I renamed URL Schemes key to CFBundleURLSchemes: Before: <key>CFBundleURLTypes</key> <array> <dict> <key>URL Schemes</key> <array> <string>fb***</string> </array> </dict> </array> After: <key>CFBundleURLTypes</key> <array> <dict> <key>CFBundleURLSchemes</key> <array> <string>fb***</string> </array> </dict> </array> The difference is not visible in XCode because CFBundleURLSchemes is aliased with URL Schemes. As a consequence, you have to edit myapp-Info.plist manually.
You can do “Create Test App” and replace your App ID and Secret using the test app.
Caused by: The SDK has not been initialized, make sure to call FacebookSdk.sdkInitialize() first. Make sure you initialized facebook SDK before setContentView. FacebookSdk.sdkInitialize(getApplicationContext()); setContentView(R.layout.activity_main);
You need to send a complete form. The easiest way to find out what Facebook expects is to use something like Google Chrome’s developer tools to monitor your web requests. To make your life easier I’ve monitored my own login on Facebook, and reproduced it below (with private information redacted, obviously) with the unimportant information … Read more
