Android - Facebook SDK 4.30 Initialization

Question

I get the following error when trying to login by Facebook when using the latest SDK version which is 4.30:

The SDK has not been initialized, make sure to call FacebookSdk.sdkInitialize()

Then the application crashes.

Although, in the official documentation it's supposed to be already auto initialized.

Note that FacebookSdk.sdkInitialize() is deprecated now so it should not be called!

Error Log when not calling FacebookSdk.sdkInitialize() :

  The SDK has not been initialized, make sure to call
 FacebookSdk.sdkInitialize() first.   at

When forcing to call the deprecated FacebookSdk.sdkInitialize() in the application on create the following error occurs:

java.lang.NoClassDefFoundError: Failed resolution of:
Lcom/facebook/common/R$layout;                    at

at android.app.Activity.performCreate(Activity.java:6684)    at

P.S: I get an error when trying to use the Facebook login button

Error inflating class com.facebook.login.widget.LoginButton

Answer 1

Just a reminder, if one do define like this

<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="1234"/>

Not what is required in the https://developers.facebook.com/docs/android/getting-started

<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id"/>

They will get

The SDK has not been initialized, make sure to call FacebookSdk.sdkInitialize()

I meet this scenario in Facebook Share SDK 4.31.0

compile 'com.facebook.android:facebook-share:4.31.0'

This issue generally occurs when you forget to add the Facebook app id in the manifest file.

Follow these steps to make sure that you do not miss something.
