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/deehidayat/react-native-ocr-reader.git in your main project.

3. Link the library:

   • Add the following to android/settings.gradle:

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

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

     ...
     
     dependencies {
         ...
         compile project(':react-native-ocr-reader')
     }

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

     package com.motivation;
     
     import com.google.android.gms.samples.vision.ocrreader.OcrReaderPackage;  // add this for react-native-ocr-reader
     
     public class MainApplication extends Application implements ReactApplication {
     
         @Override
         protected List<ReactPackage> getPackages() {
             return Arrays.<ReactPackage>asList(
                 new MainReactPackage(),
                 new OcrReaderPackage()     // add this for react-native-ocr-reader
             );
         }
     }

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

   import OcrReader from 'react-native-ocr-reader'
   <OcrReader
       style={{flex: 1}}
       onTextRead={({data})=>{ console.log(data) }}
       />

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.
