This file ought to lengthen `ReactActivity` (or `ReactFragmentActivity` for those who choose fragments).“`javaimport com.fb.react.ReactActivity;import com.fb.react.ReactActivityDelegate;import com.fb.react.defaults.DefaultNewArchitectureEntryPoint;import com.fb.react.defaults.DefaultReactActivityDelegate;public class MainActivity extends ReactActivity / Returns the title of the primary element registered from JavaScript. That is used to schedule

rendering of the element.

– / @Override protected String getMainComponentName() return “MyReactNativeApp”; // Substitute together with your app’s title / Returns the occasion of the @hyperlink ReactActivityDelegate. Right here we use a util class @hyperlink

DefaultReactActivityDelegate which lets you simply allow Material and Concurrent React

(aka React 18) with two boolean flags.

– / @Override protected ReactActivityDelegate createReactActivityDelegate() return new DefaultReactActivityDelegate( this, getMainComponentName(), // If you happen to opted-in for the New Structure, we allow the Material by default. DefaultNewArchitectureEntryPoint.getFabricEnabled()); “`Keep in mind to interchange `”MyReactNativeApp”` with the title of your React Native app, as outlined in your `index.js` file.After making these modifications, sync your Gradle information in Android Studio.
