+  - Add `new RNRootViewBackgroundPackage()` to the list returned by the `getPackages()` method
+2. Append the following lines to `android/settings.gradle`:
+  	```
+  	include ':react-native-root-view-background'
+  	project(':react-native-root-view-background').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-root-view-background/android')
+  	```
+3. Insert the following lines inside the dependencies block in `android/app/build.gradle`:
