Requirements

JDK >= 1.7 (if you run on 1.6 you will get an error on "_cameras = new HashMap<>();")
With iOS 10 and higher you need to add the "Privacy - Camera Usage Description" key to the Info.plist of your project. This should be found in 'your_project/ios/your_project/Info.plist'. Add the following code:

<key>NSCameraUsageDescription</key>
<string>Your message to user when the camera is accessed for the first time</string>

<!-- Include this only if you are planning to use the camera roll -->
<key>NSPhotoLibraryUsageDescription</key>
<string>Your message to user when the photo library is accessed for the first time</string>

<!-- Include this only if you are planning to use the microphone for video recording -->
<key>NSMicrophoneUsageDescription</key>
<string>Your message to user when the microphone is accessed for the first time</string>

On Android, you require buildToolsVersion of 25.0.2+. This should easily and automatically be downloaded by Android Studio's SDK Manager.
On iOS 11 and later you need to add NSPhotoLibraryAddUsageDescription key to the Info.plist. This key lets you describe the reason your app seeks write-only access to the user’s photo library. Info.plist can be found in 'your_project/ios/your_project/Info.plist'. Add the following code:

<!-- Include this only if you are planning to use the camera roll -->
<key>NSPhotoLibraryAddUsageDescription</key>
<string>Your message to user when the photo library is accessed for the first time</string>

Mostly automatic install with react-native

npm install react-native-camera --save
react-native link react-native-camera To install it with Windows, see manual install below

Mostly automatic install with CocoaPods

npm install react-native-camera --save
Add the plugin dependency to your Podfile, pointing at the path where NPM installed it:

pod 'react-native-camera', path: '../node_modules/react-native-camera'

Run pod install

Note: You might need to adjust your Podfile following the example below:

target 'yourTargetName' do
  # See http://facebook.github.io/react-native/docs/integration-with-existing-apps.html#configuring-cocoapods-dependencies
  pod 'React', :path => '../node_modules/react-native', :subspecs => [
    'Core',
    'CxxBridge', # Include this for RN >= 0.47
    'DevSupport', # Include this to enable In-App Devmenu if RN >= 0.43
    'RCTText',
    'RCTNetwork',
    'RCTWebSocket', # Needed for debugging
    'RCTAnimation', # Needed for FlatList and animations running on native UI thread
    # Add any other subspecs you want to use in your project
  ]

  # Explicitly include Yoga if you are using RN >= 0.42.0
  pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'

  # Third party deps podspec link
  pod 'react-native-camera', path: '../node_modules/react-native-camera'

end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == "React"
      target.remove_from_project
    end
  end
end

Manual install

iOS

npm install react-native-camera --save
In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
Go to node_modules ➜ react-native-camera and add RNCamera.xcodeproj
Expand the RNCamera.xcodeproj ➜ Products folder
In XCode, in the project navigator, select your project. Add libRNCamera.a to your project's Build Phases ➜ Link Binary With Libraries
Click RNCamera.xcodeproj in the project navigator and go the Build Settings tab. Make sure 'All' is toggled on (instead of 'Basic'). In the Search Paths section, look for Header Search Paths and make sure it contains both $(SRCROOT)/../../react-native/React and $(SRCROOT)/../../../React - mark both as recursive.

Face Detection/Text Recognition/BarCode(using MLKit) Steps

Face Detection/Text Recognition/BarCode(using MLKit) are optional on iOS. If you want them, you will need to use CocoaPods path and set-up Firebase project for your app (detailed steps below).

Note: Installing react-native-firebase package is NOT necessary.

Modifying Podfile

Modify the dependency towards react-native-camera in your Podfile, from

pod 'react-native-camera', path: '../node_modules/react-native-camera'

to (for Face Detection)

pod 'react-native-camera', path: '../node_modules/react-native-camera', subspecs: [
  'FaceDetectorMLKit'
]

or to (for Text Recognition)

pod 'react-native-camera', path: '../node_modules/react-native-camera', subspecs: [
  'TextDetector'
]

or to (for Barcode Recognition)

pod 'react-native-camera', path: '../node_modules/react-native-camera', subspecs: [
  'BarcodeDetectorMLKit'
]

or to (all possible detections)

pod 'react-native-camera', path: '../node_modules/react-native-camera', subspecs: [
  'TextDetector',
  'FaceDetectorMLKit',
  'BarcodeDetectorMLKit'
]

Setting up Firebase

Text/Face recognition for iOS uses Firebase MLKit which requires setting up Firebase project for your app. If you have not already added Firebase to your app, please follow the steps described in getting started guide. In short, you would need to

Register your app in Firebase console.
Download GoogleService-Info.plist and add it to your project
Add pod 'Firebase/Core' to your podfile
In your AppDelegate.m file add the following lines:

#import <Firebase.h> // <--- add this
...

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  [FIRApp configure]; // <--- add this
  ...
}

If you have issues with duplicate symbols you will need to enable dead code stripping option in your Xcode (Target > Build Settings > search for "Dead code stripping") see here.
If you are using pod Firebase/Core with a version set below 5.13 you might want to add pod 'GoogleAppMeasurement', '~> 5.3.0' to your podfile

Android

npm install react-native-camera --save
Open up android/app/src/main/java/[...]/MainApplication.java

Add import org.reactnative.camera.RNCameraPackage; to the imports at the top of the file
Add new RNCameraPackage() to the list returned by the getPackages() method. Add a comma to the previous item if there's already something there.

Append the following lines to android/settings.gradle:

include ':react-native-camera'
project(':react-native-camera').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-camera/android')

Insert the following lines in android/app/build.gradle:

inside the dependencies block:

```gradle
implementation project(':react-native-camera')
```

inside defaultConfig block insert either:

android {
  ...
  defaultConfig {
    ...
    missingDimensionStrategy 'react-native-camera', 'general' <-- insert this line
  }
}

or, if using MLKit for text/face/barcode recognition:

android {
  ...
  defaultConfig {
    ...
    missingDimensionStrategy 'react-native-camera', 'mlkit' <-- insert this line
  }
}

Declare the permissions in your Android Manifest (required for video recording feature)

<uses-permission android:name="android.permission.RECORD_AUDIO"/>
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Add jitpack to android/build.gradle

allprojects {
    repositories {
        maven { url "https://www.jitpack.io" }
        maven { url "https://maven.google.com" }
    }
}

Additional steps for using MLKit for text/face/barcode recognition

7.1. Using Firebase MLKit requires seting up Firebase project for your app. If you have not already added Firebase to your app, please follow the steps described in getting started guide. In short, you would need to
- Register your app in Firebase console.
- Download google-services.json and place it in android/app/
- add the folowing to project level build.gradle:
```
    buildscript {
      dependencies {
      // Add this line
      classpath 'com.google.gms:google-services:4.0.1' <-- you might want to use different version
      }
    }
```
- add to the bottom of android/app/build.gradle file
```
apply plugin: 'com.google.gms.google-services'
```
7.2. Configure your app to automatically download the ML model to the device after your app is installed from the Play Store. If you do not enable install-time model downloads, the model will be downloaded the first time you run the on-device detector. Requests you make before the download has completed will produce no results.
```
<application ...>
...
  <meta-data
      android:name="com.google.firebase.ml.vision.DEPENDENCIES"
      android:value="ocr" />
  
</application>
```

The current Android library defaults to the below values for the Google SDK and Libraries,

def DEFAULT_COMPILE_SDK_VERSION             = 26
def DEFAULT_BUILD_TOOLS_VERSION             = "26.0.2"
def DEFAULT_TARGET_SDK_VERSION              = 26
def DEFAULT_GOOGLE_PLAY_SERVICES_VERSION    = "12.0.1"
def DEFAULT_SUPPORT_LIBRARY_VERSION         = "27.1.0"

You can override this settings by adding a Project-wide gradle configuration properties for use by all modules in your ReactNative project by adding the below to android/build.gradle file,

buildscript {...}

allprojects {...}

/**
* Project-wide gradle configuration properties for use by all modules
*/
ext {
    compileSdkVersion           = 26
    targetSdkVersion            = 26
    buildToolsVersion           = "26.0.2"
    googlePlayServicesVersion   = "12.0.1"
    googlePlayServicesVisionVersion = "15.0.2"
    supportLibVersion           = "27.1.0"
}

The above settings in the ReactNative project over-rides the values present in the react-native-camera module. For your reference below is the android/build.gradle file of the module.

def safeExtGet(prop, fallback) {
    rootProject.ext.has(prop) ? rootProject.ext.get(prop) : fallback
}

buildscript {
  repositories {
    google()
    maven {
      url 'https://maven.google.com'
    }
    jcenter()
  }

  dependencies {
    classpath 'com.android.tools.build:gradle:3.3.1'
  }
}

apply plugin: 'com.android.library'

android {
  compileSdkVersion safeExtGet('compileSdkVersion', 28)
  buildToolsVersion safeExtGet('buildToolsVersion', '28.0.3')

  defaultConfig {
    minSdkVersion safeExtGet('minSdkVersion', 16)
    targetSdkVersion safeExtGet('targetSdkVersion', 28)
  }

  flavorDimensions "react-native-camera"

  productFlavors {
    general {
      dimension "react-native-camera"
    }
    mlkit {
      dimension "react-native-camera"
    }
  }

  sourceSets {
    main {
      java.srcDirs = ['src/main/java']
    }
    general {
      java.srcDirs = ['src/general/java']
    }
    mlkit {
      java.srcDirs = ['src/mlkit/java']
    }
  }

  lintOptions {
    abortOnError false
    warning 'InvalidPackage'
  }
}

repositories {
  google()
  jcenter()
  maven {
   url 'https://maven.google.com'
  }
  maven { url "https://jitpack.io" }
  maven {
    // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
    url "$rootDir/../node_modules/react-native/android"
  }
}

dependencies {
  def googlePlayServicesVisionVersion = safeExtGet('googlePlayServicesVisionVersion', safeExtGet('googlePlayServicesVersion', '17.0.2'))

  implementation 'com.facebook.react:react-native:+'
  implementation "com.google.zxing:core:3.3.3"
  implementation "com.drewnoakes:metadata-extractor:2.11.0"
  generalImplementation "com.google.android.gms:play-services-vision:$googlePlayServicesVisionVersion"
  implementation "com.android.support:exifinterface:${safeExtGet('supportLibVersion', '28.0.0')}"
  implementation "com.android.support:support-annotations:${safeExtGet('supportLibVersion', '28.0.0')}"
  implementation "com.android.support:support-v4:${safeExtGet('supportLibVersion', '28.0.0')}"
  mlkitImplementation "com.google.firebase:firebase-ml-vision:${safeExtGet('firebase-ml-vision', '19.0.3')}"
  mlkitImplementation "com.google.firebase:firebase-ml-vision-face-model:${safeExtGet('firebase-ml-vision-face-model', '17.0.2')}"
}

If you are using a version of googlePlayServicesVersion that does not have play-services-vision, you can specify a different version of play-services-vision by adding googlePlayServicesVisionVersion to the project-wide properties

ext {
    compileSdkVersion           = 26
    targetSdkVersion            = 26
    buildToolsVersion           = "26.0.2"
    googlePlayServicesVersion   = "16.0.1"
    googlePlayServicesVisionVersion = "15.0.2"
    supportLibVersion           = "27.1.0"
}

Windows

npm install react-native-camera --save
Link the library as described here: react-native-windows / LinkingLibrariesWindows.md For the last step of this guide, you have to add the following things to your MainReactNativeHost.cs:

in the import section at the very top: using RNCamera;
in protected override List<IReactPackage> Packages => new List<IReactPackage> add a new line with new RNCameraPackage()

Add the capabilities (permissions) for the webcam and microphone as described here: docs.microsoft / audio-video-camera
Use RCTCamera (RNCamera is not supported yet) like described above

Follow the Q & A section if you are having compilation issues.
