CodePudding user response：

You didn't add any code explaining the problem but after searching for this problem I found that you should add SDK initializes method in youronCreate() like the following

    @Override
    public void onCreate() {
        super.onCreate();
        FacebookSdk.sdkInitialize(getApplicationContext());
        AppEventsLogger.activateApp(this);
    }

CodePudding user response：

To use Facebook Ads Sdk in your app, You must make an App class for your app and initialize the sdk there.

import android.app.Application;

public class App extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        FacebookSdk.sdkInitialize(getApplicationContext());
        AppEventsLogger.activateApp(this);
    }
}

And set it in your manifest.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools">

    <application
        android:name=".App"  <!-- Name of your app class -->
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        ........
        ........

    </application>
</manifest>
