Example of Image Picker in React Native

React Native Image Picker

Here is an example of Image Picker in React Native. For picking the image we will use a very good library called react-native-image-picker. It is a React Native module that allows you to select a photo/video from the device library or camera. It is very simple and straight forward.

You have so many options while choosing the image/video like you can decide the maxWidth and maxHeight if the image, you can set the quality of the image/video using quality (0-1), videoQuality(low-high), in case you want to use it to record video then you can set the video max duration in seconds, also you will have the option to saves the image/video file captured to public photos.

A new version of React Native Image Picker is out. We have updated the post for latest V3.+ version also.

How to Use ImagePicker Component?

Before the last major update in  library (Major update: V 3.+)

react-native-image-picker library provided an ImagePicker component in which you can set the options like the title of the picker, Your custom Buttons(Name and title of the button) and storage options like skipBackup or path.
Here is the code snippet of ImagePicker we have used in this Example

var options = {
   title: 'Select Image',
   customButtons: [
     {
       name: 'customOptionKey',
       title: 'Choose Photo from Custom Option'
     },
   ],
   storageOptions: {
     skipBackup: true,
     path: 'images',
   },
};
ImagePicker.showImagePicker(options, response => {
   console.log('Response = ', response);
   if (response.didCancel) {
     console.log('User cancelled image picker');
   } else if (response.error) {
     console.log('ImagePicker Error: ', response.error);
   } else if (response.customButton) {
     console.log(
       'User tapped custom button: ',
       response.customButton
     );
     alert(response.customButton);
   } else {
     setFilePath(response);
   }
});

But now after version 3.+

You will have different API to access the images/video, You can now

1. Click images
2. Record Videos
3. Pick Images
4. Pick Videos

Now we have two different APIs launchCamera and launchImageLibrary. This is very easy to use and works perfectly for Android and iOS both.

Image Picker Example Description

In this example below, we will have 4 different buttons on a screen and on click of each button user can

1. Click image and captured image path will be returned
2. Record video and recorded video path will be returned
3. Pick image from gallery
4. Pick video from gallery

So Let’s get started with our Example.

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 command line interface to make our React Native App.

If you have previously installed a global react-native-cli package, please remove it as it may cause unexpected issues:

npm uninstall -g react-native-cli @react-native-community/cli

Run the following commands to create a new React Native project

npx react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

npx react-native init ProjectName --version X.XX.X

Note If the above command is failing, you may have old version of react-native or react-native-cli installed globally on your pc. Try uninstalling the cli and run the cli using npx.

This will make a project structure with an index file named App.js in your project directory.

Installation of Dependency

To use ImagePicker we need to install react-native-image-picker dependency.

To install this open the terminal and jump into your project using

cd ProjectName

Run the following command

npm install react-native-image-picker --save

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-image-picker.

CocoaPods Installation

After the updation of React Native 0.60, they have introduced autolinking so we do not require to link the library but need to install pods. So to install pods use

cd ios && pod install && cd ..

Android Permission to use the Camera and to Read the Storage

We are using a Native API Camera and also going to choose the image from the gallery so we need to add some permission to the AndroidManifest.xml file.

Please add the following permissions in the AndroidManifest.xml

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

Permission	Purpose
CAMERA	To access the camera
WRITE_EXTERNAL_STORAGE	To Read and Write the content in the SD card

For more about the permission, you can see this post.

IOS Permission to use the Camera and to Read the Storage

1. Open the project ImagePickerExample -> ios -> ImagePickerExample.xcodeproj in XCode. Click on Project (ImagePickerExample in my case) from the left sidebar and you will see multiple options in the workspace.

2. Select info tab which is info.plist

3. Click on the plus button to add following permission key and value which will be visible when permission dialog pops up.

• If you are allowing user to select image/video from photos, add “Privacy – Photo Library Additions Usage Description”.
• To capture image add “Privacy – Camera Usage Description”.
• If you are allowing user to capture video add “Privacy – Camera Usage Description” add “Privacy – Microphone Usage Description”.

Key	Value
Privacy – Photo Library Additions Usage Description	App needs photo library Access
Privacy – Camera Usage Description	App needs Camera Access Permission for testing
Privacy – Microphone Usage Description	App needs Microphone Access Permission for testing

Code for Image Picker in React Native (Image Picker V2.+)

To Run the React Native App

Open the terminal again and jump into your project using.

cd ProjectName

1. Start Metro Bundler

First, you will need to start Metro, the JavaScript bundler that ships with React Native. To start Metro bundler run following command:

npx react-native start

Once you start Metro Bundler it will run forever on your terminal until you close it. Let Metro Bundler run in its own terminal. Open a new terminal and run the application.

2. Start React Native Application

To run the project on an Android Virtual Device or on real debugging device:

npx react-native run-android

or on the iOS Simulator by running (macOS only)

npx react-native run-ios

Known Issue

In case you face any min version issue in Android then you can update minSdkVersion to 21 in yourProject/android/build.gradle

ext {
    buildToolsVersion = "29.0.2"
    minSdkVersion = 21
    compileSdkVersion = 29
    targetSdkVersion = 29
}
