A React Native module that Allows you to use Native UI to Select media from the Device

React Native Image Picker

A React Native module that allows you to use native UI to select a photo/video from the device library or directly from the camera.

iOS Android

Before you open an issue

This library started as a basic bridge of the native iOS image picker, and I want to keep it that way. As such, functionality beyond what the native UIImagePickerController supports will not be supported here. Multiple image selection, more control over the crop tool, and landscape support are things missing from the native iOS functionality - not issues with my library. If you need these things, react-native-image-crop-picker might be a better choice for you.

Install

NOTE: THIS PACKAGE IS NOW BUILT FOR REACT NATIVE 0.40 OR GREATER! IF YOU NEED TO SUPPORT REACT NATIVE < 0.40, YOU SHOULD INSTALL THIS PACKAGE @0.24

npm install [[email protected]](/cdn-cgi/l/email-protection) --save

Automatic Installation

react-native link

IMPORTANT NOTE: You’ll still need to perform step 4 for iOS and steps 2 and 5 for Android of the manual instructions below.

Manual Installation

iOS

  1. In the XCode’s “Project navigator”, right click on your project’s Libraries folder ➜ Add Files to <...>
  2. Go to node_modulesreact-native-image-pickerios ➜ select RNImagePicker.xcodeproj
  3. Add RNImagePicker.a to Build Phases -> Link Binary With Libraries
  4. For iOS 10+, Add the NSPhotoLibraryUsageDescription, NSCameraUsageDescription, NSPhotoLibraryAddUsageDescription and NSMicrophoneUsageDescription (if allowing video) keys to your Info.plist with strings describing why your app needs these permissions. Note: You will get a SIGABRT crash if you don’t complete this step
<plist version="1.0">
  <dict>
    ...
    <key>NSPhotoLibraryUsageDescription</key>
    <string>$(PRODUCT_NAME) would like access to your photo gallery</string>
    <key>NSCameraUsageDescription</key>
    <string>$(PRODUCT_NAME) would like to use your camera</string>
    <key>NSPhotoLibraryAddUsageDescription</key>
    <string>$(PRODUCT_NAME) would like to save photos to your photo gallery</string>
    <key>NSMicrophoneUsageDescription</key>
    <string>$(PRODUCT_NAME) would like to your microphone (for videos)</string>
  </dict>
</plist>

  1. Compile and have fun

Android

  1. Add the following lines to android/settings.gradle:

    include ':react-native-image-picker'
    project(':react-native-image-picker').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-image-picker/android')
    
    
  2. Update the android build tools version to 2.2.+ in android/build.gradle:

    buildscript {
        ...
        dependencies {
            classpath 'com.android.tools.build:gradle:2.2.+' // <- USE 2.2.+ version
        }
        ...
    }
    ...
    
    
  3. Update the gradle version to 2.14.1 in android/gradle/wrapper/gradle-wrapper.properties:

    ...
    distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip
    
    
  4. Add the compile line to the dependencies in android/app/build.gradle:

    dependencies {
        compile project(':react-native-image-picker')
    }
    
    
  5. Add the required permissions in AndroidManifest.xml:

    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    
    
  6. Add the import and link the package in MainApplication.java:

    import com.imagepicker.ImagePickerPackage; // <-- add this import
    
    public class MainApplication extends Application implements ReactApplication {
        @Override
        protected List<ReactPackage> getPackages() {
            return Arrays.<ReactPackage>asList(
                new MainReactPackage(),
                new ImagePickerPackage() // <-- add this line
                // OR if you want to customize dialog style
                new ImagePickerPackage(R.style.my_dialog_style)
            );
        }
    }
    
    
Android (Optional)

Customization settings of dialog android/app/res/values/themes.xml (android/app/res/values/style.xml is a valid path as well):

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="DefaultExplainingPermissionsTheme" parent="Theme.AppCompat.Light.Dialog.Alert">
        <!-- Used for the buttons -->
        <item name="colorAccent">@color/your_color</item>

        <!-- Used for the title and text -->
        <item name="android:textColorPrimary">@color/your_color</item>

        <!-- Used for the background -->
        <item name="android:background">@color/your_color</item>
    </style>
</resources>

If MainActivity is not instance of ReactActivity, you will need to implement OnImagePickerPermissionsCallback to MainActivity:

import com.imagepicker.permissions.OnImagePickerPermissionsCallback; // <- add this import
import com.facebook.react.modules.core.PermissionListener; // <- add this import

public class MainActivity extends YourActivity implements OnImagePickerPermissionsCallback {
  private PermissionListener listener; // <- add this attribute

  // Your methods here

  // Copy from here

  @Override
  public void setPermissionListener(PermissionListener listener)
  {
    this.listener = listener;
  }

  @Override
  public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults)
  {
    if (listener != null)
    {
      listener.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
  }

  // To here
}

This code allows to pass result of request permissions to native part.

Usage

var ImagePicker = require('react-native-image-picker');

// More info on all the options is below in the README...just some common use cases shown here
var options = {
  title: 'Select Avatar',
  customButtons: [
    {name: 'fb', title: 'Choose Photo from Facebook'},
  ],
  storageOptions: {
    skipBackup: true,
    path: 'images'
  }
};

/**
 * The first arg is the options object for customization (it can also be null or omitted for default options),
 * The second arg is the callback which sends object: response (more info below in README)
 */
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);
  }
  else {
    let source = { uri: response.uri };

    // You can also display the image using data:
    // let source = { uri: 'data:image/jpeg;base64,' + response.data };

    this.setState({
      avatarSource: source
    });
  }
});

Then later, if you want to display this image in your render() method:

<Image source={this.state.avatarSource} style={styles.uploadAvatar} />

Directly Launching the Camera or Image Library

To Launch the Camera or Image Library directly (skipping the alert dialog) you can
do the following:

// Launch Camera:
ImagePicker.launchCamera(options, (response)  => {
  // Same code as in above section!
});

// Open Image Library:
ImagePicker.launchImageLibrary(options, (response)  => {
  // Same code as in above section!
});

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.
