Getting started: React Native 0.60 - Android Issue - Result: ERROR: The modules ['react-native-notifications', 'reactnativenotifications'] point to the same directory in the file system.

Hi,

I’ve been having issues getting react-native-notifications to build on a freshly created 0.60.0 project and having searched far and wide for fixes (google, stackoverflow, the issues archive here) I’ve drawn a blank so hoping someone smarter than ourselves can help us out! This post details every step from react-native init (0.60.0) to our blocking problem.

Issue: Unable to create Android build using the instructions on Install Instructions

Steps to reproduce:

Create a new project (0.60.0)

Install react-native-notifications - note: we use yarn add react-native-notifcations - should this make any difference?

Manual Step 1: Add a reference to the library’s native code in your global settings.gradle:

Manual Step 2: Declare the library as a dependency in your app-project’s build.gradle: Note: compile is obsolete - the install instructions should give the example with implementation, but for sake of following the instructions precisely…

Manual Step 3: Add the library to your application class (e.g. MainApplication.java): react-native 0.60.0 introduces auto-linking. The instructions say that you should add the following to MainApplication.java:

import com.wix.reactnativenotifications.RNNotificationsPackage; ... @Override protected List<ReactPackage> getPackages() { return Arrays.<ReactPackage>asList( new MainReactPackage(), // ... // Add this line: new RNNotificationsPackage(MainApplication.this) );

However, the format of the package lists has changed to:

@Override protected List<ReactPackage> getPackages() { @SuppressWarnings("UnnecessaryLocalVariable") List<ReactPackage> packages = new PackageList(this).getPackages(); // Packages that cannot be autolinked yet can be added manually here, for example: // packages.add(new MyReactNativePackage()); return packages; }

With React 0.60.0 auto-linking (should) negate the need to specify the RNNotificationsPackage, however, it results in the following error : Result: ERROR: The modules [‘react-native-notifications’, ‘reactnativenotifications’] point to the same directory in the file system.

Any ideas on how to resolve this?

If anyone is looking for a solution:

1. open a new file named react-native.config.js in your root folder, add the following content: module.exports = { dependencies: { ‘react-native-notifications’: { platforms: { android: null } } } };

2. root/android/app/src/main/java/<yourpackage>/MainApplication.java: add to:

@Override protected List<ReactPackage> getPackages() { @SuppressWarnings(“UnnecessaryLocalVariable”) List<ReactPackage> packages = new PackageList(this).getPackages();

•  packages.add(new RNNotificationsPackage(MainApplication.this));
  return packages;
  

  }

Tried with no sucess. I got this:
