React Native Camera

We all usually need a camera in our app and Wix has provided a very good library named react-native-camera-kit. Which is very easy to integrate into your app. So let’s get started.

As you want to use the native Camera API you need to do some additional changes in different files to access the camera.

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App.

Assuming that you have node installed, you can use npm to install the react-native-cli command line utility.
Open the terminal and go to the workspace and run Run the following commands to create a new React Native project This will make a project structure with an index file named App.js in your project directory.

Installation of Dependency

To use <CameraKitCameraScreen /> we need to install react-native-camera-kit package. To install this

Open the terminal and jump into your project

Run the following command

This command will copy all the dependencies into your node_module directory, You can find the directory in node_module the directory named react-native-camera-kit.

–save is optional, it is just to update the react-native-camera-kit dependancy in your package.json file.

Dependency Version for this Example Used is

Permission to use the camera and other configurations

We are using an Android Native API Camera so we need to add some permission to the AndroidManifest.xml file. On devices before SDK version 23, the permissions are automatically granted if they appear in the manifest but after SDK version 23 android applies new permissions model. For more about the permission, you can see this post.

So we are going to add the following permissions in the AndroidMnifest.xml

CAMERATo access the camera
WRITE_EXTERNAL_STORAGETo store the content in the SD card
READ_EXTERNAL_STORAGETo view the content of the SD card

By adding permission in AndroidManifest.xml you are able to work with the CAMERA and EXTERNAL_STORAGE in devices which are lower than API 23. But if you want to access the CAMERA in higher level devices you also need to ask for the runtime permission.

For this example, we also need to add some additional libraries and lines to do a suitable configuration. Please do check your compileSdkVersion and targetSdkVersion is above or equal 23. Go to the CameraExample > android > app > build.gradle.

For the example, I am using this configuration. With the extra line multiDexEnabled true which is to solve the problem of multidex faced many times.

After that scroll down and add the following dependencies.

Open CameraExample > android > settings.gradle and add the following lines

Open CameraExample > android > app > src > main > java > com > cameraexample >  and add following lines in imports

and in getPackages after new MainReactPackage() add a comma(,) and add

Open App.js in any code editor and replace the code with the following code.


Before running the app you need to make a directory called “assets ” to keep the images that we have used. Download and put all the images in assets as shown


To Run the React Native App

Open the terminal again and jump into your project using. To run the project on an Android Virtual Device or on real debugging device or on the iOS Simulator by running

That was the React Native Camera. If you have any doubt or you want to share something about the topic you can comment below or contact us here. There will be more posts coming soon. Stay tuned!

  1. The code works fine on android but does not work properly on IOS. It seems the permission functions are only for android so the code keeps getting stuck in the try catch. Any ideas?

    1. Hello,
      I have tried it on IOS also but let me confirm if there is any update in it..
      We will confirm you soon.
      Mean while if you found the problem and solution for that please comment to help others..

  2. in this package. in the galleryScreen. if i tap on image the image url is only appended to the state.
    how can i append the full image object with all the attributes i.e filename, size, url etc

    onTapImage(event) {
    const uri = event.nativeEvent.selected;

    if (this.state.images[uri]) {
    delete this.state.images[uri];
    } else {
    this.state.images[uri] = true;
    this.setState({ images: {…this.state.images }})
