Problem
While integrating Android SDK for a react-native project, I had finished the Android with React Native v0.30+ Project Configuration guide, and ran react-native run-android and then got this screen:

I learned that FacebookSdk.sdkInitialize is deprecated. see here
After some searching, I realized that the guide did not contain the steps to add the Facebook App ID for my app.
Solution
-
Open
android/app/src/main/AndroidManifest.xmlfile and look in the<application>tag to confirm that thismeta-datatag exists:<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id"/> -
Open
android/app/src/main/res/values/strings.xmlfile and confirm that this there is a “facebook_app_id” string tag with your app id as the value:<string name="facebook_app_id">YOUR_APP_ID_HERE</string> -
Run
react-native run-android.
These are the steps that worked for me.
