Hello Everyone,
I couldn't solve an issue for a week. Decided to text here for help.

I followed documentation and checked it several times. Everything is correct. But i am still getting the following error for MainApplication.java

Task :app:compileAmazonDebugJavaWithJavac FAILED
C:\Users\OMEN\Repos\DsvlineApp\android\app\src\main\java\com\dsvline\dsvlineapp\MainApplication.java:12: error: package com.dooboolab.rniap does not exist
import com.dooboolab.rniap.RNIapPackage;

packages.add(new RNIapPackage());
