PermissionsAndroid

Project with Native Code Required

This API only works in projects made with react-native init or in those made with expo init or Create React Native App which have since ejected. For more information about ejecting, please see the guide on the Create React Native App repository.

PermissionsAndroid provides access to Android M's new permissions model. The so-called "normal" permissions are granted by default when the application is installed as long as they appear in AndroidManifest.xml. However, "dangerous" permissions require a dialog prompt. You should use this module for those permissions.

On devices before SDK version 23, the permissions are automatically granted if they appear in the manifest, so check should always result to true and request should always resolve to PermissionsAndroid.RESULTS.GRANTED.

If a user has previously turned off a permission that you prompt for, the OS will advise your app to show a rationale for needing the permission. The optional rationale argument will show a dialog prompt only if necessary - otherwise the normal permission prompt will appear.

Example

import {PermissionsAndroid} from 'react-native';

async function requestCameraPermission() {
  try {
    const granted = await PermissionsAndroid.request(
      PermissionsAndroid.PERMISSIONS.CAMERA,
      {
        title: 'Cool Photo App Camera Permission',
        message:
          'Cool Photo App needs access to your camera ' +
          'so you can take awesome pictures.',
        buttonNeutral: 'Ask Me Later',
        buttonNegative: 'Cancel',
        buttonPositive: 'OK',
      },
    );
    if (granted === PermissionsAndroid.RESULTS.GRANTED) {
      console.log('You can use the camera');
    } else {
      console.log('Camera permission denied');
    }
  } catch (err) {
    console.warn(err);
  }
}

Parameters:

Name	Type	Required	Description
permission	string	Yes	The permission to check for.

---

request()

request(permission, [rationale]);

Prompts the user to enable a permission and returns a promise resolving to a string value (see result strings above) indicating whether the user allowed or denied the request or does not want to be asked again.

If rationale is provided, this function checks with the OS whether it is necessary to show a dialog explaining why the permission is needed (https://developer.android.com/training/permissions/requesting.html#explain) and then shows the system permission dialog.

Parameters:

Name	Type	Required	Description
permission	string	Yes	The permission to request.
rationale	object	No	See rationale below.

Rationale:

Name	Type	Required	Description
title	string	Yes	The title of the dialog.

buttonPositive	string	Yes	The text of the positive button.
buttonNegative	string	No	The text of the negative button.
buttonNeutral	string	No	The text of the neutral button.

---

requestMultiple()

requestMultiple(permissions);

Prompts the user to enable multiple permissions in the same dialog and returns an object with the permissions as keys and strings as values (see result strings above) indicating whether the user allowed or denied the request or does not want to be asked again.

Parameters:

Name	Type	Required	Description
permissions	array	Yes	Array of permissions to request.
