Project with Native Code Required
This API only works in projects made with react-native init
or in those made with Create React Native App which have since ejected. For

the Create React Native App repository.
PermissionsAndroid
provides access to Android M's new permissions model.
Some permissions are granted by default when the application is installed
so 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
and request
should always be true.
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.'
}
)
if (granted === PermissionsAndroid.RESULTS.GRANTED) {
console.log("You can use the camera")
} else {
console.log("Camera permission denied")
}
} catch (err) {
console.warn(err)
}
}

Methods
constructor()

checkPermission()
checkPermission(permission)
DEPRECATED - use check
Returns a promise resolving to a boolean value as to whether the specified permissions has been granted
@deprecated
check()
check(permission)
Returns a promise resolving to a boolean value as to whether the specified permissions has been granted
requestPermission()
requestPermission(permission, rationale?)
DEPRECATED - use request
Prompts the user to enable a permission and returns a promise resolving to a boolean value indicating whether the user allowed or denied the request
If the optional rationale argument is included (which is an object with a
title
and message
), 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
@deprecated
request()
request(permission, rationale?)
Prompts the user to enable a permission and returns a promise resolving to a string value indicating whether the user allowed or denied the request
If the optional rationale argument is included (which is an object with a
title
and message
), 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
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 indicating whether the user allowed or denied the request
