Example app

General Usage

npm install --save react-native-permissions
rnpm link

Add permissions to manifest for android and info.plist for ios (xcode >=8). See notes below for more details.

const Permissions = require('react-native-permissions');

//...
  //check the status of a single permission
  componentDidMount() {
    Permissions.getPermissionStatus('photo')
      .then(response => {
        //response is one of: 'authorized', 'denied', 'restricted', or 'undetermined'
        this.setState({ photoPermission: response })
      });
  }

  //request permission to access photos
  _requestPermission() {
    Permissions.requestPermission('photo')
      .then(response => {
        //returns once the user has chosen to 'allow' or to 'not allow' access
        //response is one of: 'authorized', 'denied', 'restricted', or 'undetermined'
        this.setState({ photoPermission: response })
      });
  }

  //check the status of multiple permissions
  _checkCameraAndPhotos() {
    Permissions.checkMultiplePermissions(['camera', 'photo'])
      .then(response => {
        //response is an object mapping type to permission
        this.setState({ 
          cameraPermission: response.camera,
          photoPermission: response.photo,
        })
      });
  }

  // this is a common pattern when asking for permissions.
  // iOS only gives you once chance to show the permission dialog, 
  // after which the user needs to manually enable them from settings.
  // the idea here is to explain why we need access and determine if
  // the user will say no, so that we don't blow our one chance.
  // if the user already denied access, we can ask them to enable it from settings.
  _alertForPhotosPermission() {
    Alert.alert(
      'Can we access your photos?',
      'We need access so you can set your profile pic',
      [
        {text: 'No way', onPress: () => console.log('permission denied'), style: 'cancel'},
        this.state.photoPermission == 'undetermined'? 
          {text: 'OK', onPress: this._requestPermission.bind(this)}
          : {text: 'Open Settings', onPress: Permissions.openSettings}
      ]
    )
  }
//...

API

Permission statuses

Promises resolve into one of these statuses

Return value	Notes
`authorized`	user has authorized this permission
`denied`	user has denied this permission at least once. On iOS this means that the user will not be prompted again. Android users can be promted multiple times until they select ‘Never ask me again’
`restricted`	(iOS only) user is not able to grant this permission, either because it’s not supported by the device or because it has been blocked by parental controls.
`undetermined`	user has not yet been prompted with a permission dialog

Supported permission types

Name	iOS	Android
`location`	✔️	✔
`camera`	✔️	✔
`microphone`	✔️	✔
`photo`	✔️	✔
`contacts`	✔️	✔
`event`	✔️	✔
`bluetooth`	✔️	❌
`reminder`	✔️	❌
`notification`	✔️	❌
`backgroundRefresh`	✔️	❌
`storage`	❌️	✔

Methods

Method Name	Arguments	Notes
`getPermissionStatus`	`type`	- Returns a promise with the permission status. See iOS Notes for special cases
`requestPermission`	`type`	- Accepts any permission type except `backgroundRefresh`. If the current status is `undetermined`, shows the permission dialog and returns a promise with the resulting status. Otherwise, immediately return a promise with the current status. See iOS Notes for special cases
`checkMultiplePermissions`	`[types]`	- Accepts an array of permission types and returns a promise with an object mapping permission types to statuses
`getPermissionTypes`	none	- Returns an array of valid permission types
`openSettings`	none	- Switches the user to the settings page of your app (iOS 8.0 and later)
`canOpenSettings`	none	- Returns a boolean indicating if the device supports switching to the settings page

iOS Notes

Permission type bluetooth represents the status of the CBPeripheralManager. Don’t use this if only need CBCentralManager

Permission type location accepts a second parameter for requestPermission and getPermissionStatus; the second parameter is a string, either always or whenInUse(default).

Permission type notification accepts a second parameter for requestPermission. The second parameter is an array with the desired alert types. Any combination of alert, badge and sound (default requests all three)

///example
    Permissions.getPermissionStatus('location', 'always')
      .then(response => {
        this.setState({ locationPermission: response })
      })

    Permissions.requestPermission('location', 'always')
      .then(response => {
        this.setState({ locationPermission: response })
      })

    Permissions.requestPermission('notification', ['alert', 'badge'])
      .then(response => {
        this.setState({ notificationPermission: response })
      })

You cannot request microphone permissions on the simulator.

With Xcode 8, you now need to add usage descriptions for each permission you will request. Open Xcode > Info.plist > Add a key (starting with “Privacy - …”) with your kit specific permission.

Example: If you need Contacts permission you have to add the key “Privacy - Contacts Usage Description”.

Android Notes

Requires RN >= 0.29.0

All required permissions also need to be included in the Manifest before they can be requested. Otherwise requestPermission will immediately return denied.

Permissions are automatically accepted for targetSdkVersion < 23 but you can still use getPermissionStatus to check if the user has disabled them from Settings.

Here’s a map of types to Android system permissions names:
location -> android.permission.ACCESS_FINE_LOCATION
camera -> android.permission.CAMERA
microphone -> android.permission.RECORD_AUDIO
photo -> android.permission.READ_EXTERNAL_STORAGE
storage -> android.permission.READ_EXTERNAL_STORAGE
contacts -> android.permission.READ_CONTACTS
event -> android.permission.READ_CALENDAR

You can request write access to any of these types by also including the appropriate write permission in the Manifest. Read more here: https://developer.android.com/guide/topics/security/permissions.html#normal-dangerous

Setup

npm install --save react-native-permissions
rnpm link

Or manualy linking

iOS

Run open node_modules/react-native-permissions
Drag ReactNativePermissions.xcodeproj into the Libraries group of your app’s Xcode project
Add libReactNativePermissions.a to `Build Phases -> Link Binary With Libraries.

Android

Step 1 - Update Gradle Settings

// file: android/settings.gradle
...

include ':react-native-permissions'
project(':react-native-permissions').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-permissions/android')

Step 2 - Update Gradle Build

// file: android/app/build.gradle
...

dependencies {
    ...
    compile project(':react-native-permissions')
}

Step 3 - Register React Package

...
import com.joshblour.reactnativepermissions.ReactNativePermissionsPackage; // <--- import

public class MainApplication extends Application implements ReactApplication {

    ...

    @Override
    protected List<ReactPackage> getPackages() {
        return Arrays.<ReactPackage>asList(
            new MainReactPackage(),
            new ReactNativePermissionsPackage() // <------ add the package
        );
    }

    ...
}

Troubleshooting

Q: Android - `undefined is not a object (evaluating 'RNPermissions.requestPermissions')`

A: rnpm may not have linked correctly. Follow the manual linking steps and make sure the library is linked

Q: iOS - app crashes as soon as I request permission

A: starting with xcode 8, you need to add permission descriptions. see iOS notes for more details. Thanks to @jesperlndk for discovering this.

Q: iOS - app crashes when I change permissions from settings

A: This is normal. iOS restarts your app when your privacy settings change. Just google “ios crash permission change”
