npm install -g react-native-cli Now, let'south create a new React Native project, e.g. RNimagePicker
react-native init RNimagePicker
When the above command is done, open the principal folder in your preferred editor. When we open up the projection in a lawmaking editor, its construction looks like this.
2. Gear up React Native Image Picker
To useReact Native Paradigm Picker nosotros demand to install react-native-image-picker dependency.
Installation of Dependency
To add React Native Image Picker to our React Native Project, we need to run the following command at the root of the project
npm install react-native-image-picker --save
or
yarn add react-native-image-picker This command volition copy all the dependencies into your node_modules directory, Yous can find the directory in node_modules the directory named react-native-image-picker.

Now we volition run across how to give permissions in Android to use Camera and read Storage.
We are going using a Native API Camera and choose the image from the Gallery. And then, we need to provide some permission to access the Camera and Gallery.
We are going to add together the following permissions in the AndroidManifest.xml
Projection → android → app → src → debug → AndroidManifest.xml
Your AndroidManifest.xmlshould wait like this:
