Permissions When you are creating an app that requires access to potentially sensitive information on a user's device, such as their location or contacts, you need to ask for the user's permission first.
For example, to access the user's media library, you will need to use MediaLibrary. In Expo Go, there isn't much you need to think about to interact with permissions beyond requesting permissions before using certain APIs. This changes when you want to deploy your app to an app store.
Please read the permissions on iOS and permissions on Android sections carefully before deploying your app to stores. If you don't configure or explain the permissions properly it may result in your app getting rejected or pulled from the stores. Read more about deploying to the stores in the App Store Deployment Guide. Managed workflow. To request permissions on iOS, you have to describe why the permissions are requested and install the library that can request this permission. In the managed workflow, you can do that by customizing the ios.

See the Permission types below to learn about which Android permissions are added. You can find a full list of all available permissions in the Android Manifest. In the bare workflow, permissions are controlled in your project AndroidManifest. To limit the permissions your managed workflow app requires, add them them to a list of explicitly excluded permissions.
