Facebook Sdk Has Not Been Initialized FacebookSdk.sdkInitialize()

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 most of the things found on Internet but did not get anything regarding this.

Here is my MainActivity.java:

 public class MainActivity extends Activity {

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    FacebookSdk.sdkInitialize(getApplicationContext());
   } 
}

Here is My Activitymain.xml:

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:facebook="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

 <com.facebook.login.widget.LoginButton
    android:id="@+id/connectWithFbButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:layout_gravity="center_horizontal"
    android:text="  connect_with_facebook" /> 
</LinearLayout>

see my Logcat :

 05-13 16:30:39.332: E/AndroidRuntime(10264): Caused by: The SDK has not been initialized, make sure to call FacebookSdk.sdkInitialize() first.

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 2

You have to use FacebookSdk.sdkInitialize(getApplicationContext()); before setContentView(R.layout.activity_main); as documentation states out. In case you need a complete facebook login example, check this one here .

Answer 3

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.

Answer 4

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

Answer 5

For SDK v13.+ you must add Apple ID and Client Token .

1. Open the /app/res/values/strings.xml file in your app project and add:

<string name="facebook_app_id">1234</string>
<string name="facebook_client_token">56789</string>

2. Open the /app/manifests/AndroidManifest.xml file in your app project and add:

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

You can find your Client Token in your FB Developer account:

App > Dashboard > Settings > Advanced > Security > Client token.

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 7

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 8

Seeing the responses listed in this question, the old way to initialize Facebook was:

public class MyApplication extends Application {

 @Override
 public void onCreate() {
    super.onCreate();
    // Initialize the SDK before executing any other operations,
    FacebookSdk.sdkInitialize(getApplicationContext());
    AppEventsLogger.activateApp(this);
   }
 }

But we can get the message:

Facebook Sdk Has Not Been Initialized FacebookSdk.sdkInitialize()

FacebookSdk.sdkInitialize() now is deprecated.

Now (2021) Facebook initialization has changed, the Facebook initialization is automatically .

1 Add the following to the dependencies {} section of your build.gradle (module: app) file to compile the latest version of the Facebook SDK for Android:

implementation 'com.facebook.android:facebook-android-sdk:latest.release'

Add Your Facebook App ID and Client Token

Add your Facebook App ID and Client Token to your project's strings file and update your Android manifest:

1 Open your /app/res/values/strings.xml file.

2 Add a string element with the name attribute facebook_app_id and value as your Facebook App ID to the file. For example

<string name="facebook_app_id">Facebook App ID</string>
<string name="facebook_client_token">Facebook Client ID</string>

3 Open /app/manifests/AndroidManifest.xml

4 Add a uses-permission element to the manifest:

<uses-permission android:name="android.permission.INTERNET"/>

5 Add a meta-data element to the application element:

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

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 10

For Flutter Devs running into this issue.

Make sure you have followed the steps 1-6 as given in the facebook documentation .

Adding FacebookSdk.sdkInitialize() in your MainActivity file won't fix the issue.

Answer 11

If this helps anyone. For me I had to make this change

implementation 'com.facebook.android:facebook-login:latest.release' // for FB login 

the above line of code must be added to the END of the dependencies object and not anywhere in between. This is in android/app/build.gradle file

Answer 12

For me, this issue arose due to a package in my application called react-native-fbsdk. Please check your package.json file for the same.

I removed the package using npm uninstall fbsdk and rebuilt by app and it worked perfectly.

Hope this solution works for you!

Answer 13

remove android:exported=true from AndroidManifest.xml and targetSdkVersion should be less than 31

Answer 14

My app was crashing because the Privacy Policy url was not provided in "Settings/Basic" in https://developers.facebook.com/ . (in fact it was provided but I had to "Save changes" again. Seems a bug from Facebook).

The app was working fine and the error message Facebook Sdk Has Not Been Initialized FacebookSdk.sdkInitialize() disappeared. Hope this help.
