I\'m using facebook-android-sdk-4.19.0 in Android Studio and I followed the Facebook quick start guide at https://developers.facebook.com/docs/android/getting-started (Click
FacebookSdk.sdkInitialize(getApplicationContext());
No need of this method as Facebook doc says: This function initializes the Facebook SDK is called automatically on app start up if the proper entries are listed in the AndroidManifest, such as the facebook app id. Automatic event logging from 'activateApp' can be controlled via the 'com.facebook.sdk.AutoLogAppEventsEnabled' manifest setting.
