Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:
https://facebook.github.io/react-native/docs/getting-started.html

Then I have 2 imports with the same name in my /home/user/app/android/app/src/main/java/com/package/MainApplication.java
May this cause the issue?
Is this the issue with RN?

package com.package;

import android.app.Application;

import com.facebook.react.ReactApplication;
import com.amazonaws.RNAWSCognitoPackage; // 1
import com.amazonaws.amplify.pushnotification.RNPushNotificationPackage;
import com.airlabsinc.RNAWSCognitoPackage; // 2
import com.horcrux.svg.SvgPackage;
import com.toast.ToastPackage;

In my case worked deleted the old react-native-google-signin and instead let the @react-native-google-signin/google-signin in the package.json, then cleaning the Gradle, cleaning metro cache and uninstalling the app from the device.
then I runned npm run android (before check that I add the @ before the node_modules path) and its work.
