- Let's start by opening the Android project in Android Studio. In Android Studio, select Open an existing Android Studio project and open the android directory of the new project.
- We'll need two new Java classes: BackgroundTaskManager and BackgroundTaskPackage.
- Now that both classes have been created, let's open BackgroundTaskManager.java and begin implementing the native module that will wrap an AsyncTask operation, starting with imports and defining the class.

package com.multithreadingapp;import android.os.AsyncTask;import com.facebook.react.bridge.Arguments;
