Question

Hey I know this was asked before, but none of the solutions seem to help. I\'m using first time Facebook SDK in my application.

What I\'ve tried:

I had tried

Answer 1

After checking the documentation I found that they are asking to initialize FacebookSdk in Application class onCreate() Method.

Snap code from Facebook doc:

  public class MyApplication extends Application {
 // Updated your class body:
 @Override
 public void onCreate() {
    super.onCreate();
    // Initialize the SDK before executing any other operations,
    FacebookSdk.sdkInitialize(getApplicationContext());
    AppEventsLogger.activateApp(this);
   }
 }

Answer 2

Use Initialise Callback Constructor like this:

    Handler mHandler = new Handler();
            FacebookSdk.InitializeCallback initializeCallback = new FacebookSdk.InitializeCallback() {
                @Override
                public void onInitialized() {

                    mHandler.post(new Runnable() {
                        @Override
                        public void run() {
                            //UI Code Here
                        }
                    });
                }
            };
    //before setContentView()   
 FacebookSdk.sdkInitialize(getActivity().getApplicationContext(),initializeCallback);

Answer 3

There is a reason why sdkInitialize() is deprecated.

Go to your manifest file within the android folder and add following

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

After that append in your strings.xml file (res/values/strings.xml) the string entry:

<string name="facebook_app_id">APP_ID</string>

Close your Metro Builder and rebuild your Project using react-native run-android

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

1. Open android/app/src/main/AndroidManifest.xml file and look in the <application> tag to confirm that this meta-data tag exists:

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

2. Open android/app/src/main/res/values/strings.xml file 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>
   

3. Run react-native run-android.

These are the steps that worked for me.

Answer 5

Follow only 2 Step and your Facebook Sdk iw working in React Native

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

    <string name="facebook_app_id">YOUR_APP_ID_HERE</string>

Don't Need this b'coz Its Deprecated Now

  FacebookSdk.sdkInitialize(getApplicationContext());

Answer 6

You don't need to use FacebookSdk.sdkInitialize anymore. Check if your:

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

is inside <application> tag.
