React Native Android Library Boilerplate

This project serves as a boilerplate to create custom React Native native modules that can later be installed through NPM and easily be used in production.

Getting started

1. Clone the project
2. Customize the project name by doing the following:

   • Edit author and name in package.json

   • Customize the Java package name (com.domain.package) as follows:

     1. Modify it in android/src/main/AndroidManifest.xml.
     2. Rename the folders starting from android/src/main/java to match your package name.
     3. Adjust package io.cmichel.boilerplate; in the top of the Module.java and Package.java files in android/src/main//java/package/path to match it.

   • Edit the name of your module in

     @Override
     public String getName() {
         return "Boilerplate";
     }

     and adjust it in index.android.js

3. Modify/Build the Project in Android Studio
   • Start Android Studio and select File -> New -> Import Project and select the android folder of this package.
   • If you get a Plugin with id 'android-library' not found Error, install android support repository.
   • If you get asked to upgrade gradle to a new version, you can skip it.

Installing it as a library in your main project

There are many ways to do this, here's the way I do it:

1. Push it to GitHub.

2. Do npm install --save git+https://github.com/MrToph/react-native-android-library-boilerplate.git in your main project.

3. Link the library:

   • Add the following to android/settings.gradle:

     include ':react-native-android-library-boilerplate'
     project(':react-native-android-library-boilerplate').projectDir = new File(settingsDir, '../node_modules/react-native-android-library-boilerplate/android')
     

   • Add the following to android/app/build.gradle:

     ...
     
     dependencies {
         ...
         compile project(':react-native-android-library-boilerplate')
     }

   • Add the following to android/app/src/main/java/**/MainApplication.java:

     package com.motivation;
     
     import io.cmichel.boilerplate.Package;  // add this for react-native-android-library-boilerplate
     
     public class MainApplication extends Application implements ReactApplication {
     
         @Override
         protected List<ReactPackage> getPackages() {
             return Arrays.<ReactPackage>asList(
                 new MainReactPackage(),
                 new Package()     // add this for react-native-android-library-boilerplate
             );
         }
     }

4. Simply import/require it by the name defined in your library's package.json:

   import Boilerplate from 'react-native-android-library-boilerplate'
   Boilerplate.show('Boilerplate runs fine', Boilerplate.LONG)

5. You can test and develop your library by importing the node_modules library into Android Studio if you don't want to install it from git all the time.
