react-native: permission is null in react native app

If you’re working on one of the latest version of React Native it seems the problem got fixed on 0.70.7. For the rest of the unlucky mortals there is a workaround fortunately…

In order to fix this I had to create a patch using patch-package along with postinstall and update my current PermissionAndroid files to support in my case POST_NOTIFICATIONS given I’m using react-native 0.64.4. So I went ahead and updated these 2 files as detailed below:

• /node_modules/react-native/Libraries/PermissionsAndroid/NativePermissionsAndroid.js

...
| 'android.permission.RECEIVE_WAP_PUSH'
| 'android.permission.RECEIVE_MMS'
| 'android.permission.WRITE_EXTERNAL_STORAGE'; <- removed this and
| 'android.permission.WRITE_EXTERNAL_STORAGE' <- added these 2
| 'android.permission.POST_NOTIFICATIONS';
...

• /node_modules/react-native/Libraries/PermissionsAndroid/PermissionsAndroid.js

...
RECEIVE_MMS: 'android.permission.RECEIVE_MMS',
READ_EXTERNAL_STORAGE: 'android.permission.READ_EXTERNAL_STORAGE',
WRITE_EXTERNAL_STORAGE: 'android.permission.WRITE_EXTERNAL_STORAGE',
POST_NOTIFICATIONS: 'android.permission.POST_NOTIFICATIONS', <- added this
...
WRITE_CALL_LOG: string,
WRITE_CONTACTS: string,
WRITE_EXTERNAL_STORAGE: string,
POST_NOTIFICATIONS: string, <- added this
....

After this change the PermissionsAndroid module from react-native started to work again as expected without getting any permission is null error.

BTW also don’t forget to include the respective permission on the AndroidManifest, in my case was: <uses-permission android:name="android.permission.POST_NOTIFICATIONS" />

Finally be sure to set the compileSdkVersion and the targetSdkVersion to 33 for the permission prompt to show up…

My case found this error because using react-native 0.70.4 It’s map key like below at node_modules/react-native/Libraries/PermissionsAndroid/PermissionsAndroid.js

POST_NOTIFICATION: 'android.permission.POST_NOTIFICATIONS',

Then exactly It’s should be PermissionsAndroid.PERMISSIONS.POST_NOTIFICATION (Not POST_NOTIFICATIONS)

import {PermissionsAndroid} from 'react-native';
PermissionsAndroid.request(PermissionsAndroid.PERMISSIONS.POST_NOTIFICATION);

For android 33, I did this PermissionsAndroid.request('android.permission.POST_NOTIFICATIONS');

I get a red line saying

Argument of type ‘“android.permission.POST_NOTIFICATIONS”’ is not assignable to parameter of type ‘Permission’

But it still works so I just ignore this error. To fix this, I would have to upgrade my react native to a version that expects this POST_NOTIFICATION value, but I am not ready to do that upgrade quite yet.

from FCM documentation For API level 33+ you will need to request the permission manually using either the built-in react-native PermissionsAndroid APIs or a related module such as react-native-permissions

I used react-native-permissions instead of patching,

add this permission in android manifest file <uses-permission android:name="android.permission.POST_NOTIFICATIONS" />

You have to target at least SDK 33 to perform request on Android 13+. The permission is always granted for prior versions.

buildscript { ext { buildToolsVersion = “33.0.0” // <- set at least 33.x minSdkVersion = 21 compileSdkVersion = 33 // <- set at least 33 targetSdkVersion = 33 // <- set at least 33

// …

import {PERMISSIONS, request} from 'react-native-permissions';

import {Platform} from ‘react-native’; const deviceAPiLevel = Platform.Version; if (Platform.OS === ‘android’ && deviceAPiLevel >= 33) { await request(PERMISSIONS.ANDROID.POST_NOTIFICATIONS); }

I was on an older version of react-native 0.66.5

I realized that PermissionsAndroid.PERMISSIONS.POST_NOTIFICATIONS is not exported in this react-native version so I added this manually like this.

PermissionsAndroid.check('android.permission.POST_NOTIFICATIONS').then(
  async response => {

    console.log('Notification: ', response, PermissionsAndroid.PERMISSIONS);

    if(!response){
      await PermissionsAndroid.request('android.permission.POST_NOTIFICATIONS');
    }
  }
)

@jaaywags Thank a Lot Bro… Your Rocking…

MY worked versions :

buildToolsVersion = "30.0.3" minSdkVersion = 21 compileSdkVersion = 33 targetSdkVersion = 33

    And Permission requesting Type : 
    
    
    ` PermissionsAndroid.request("android.permission.POST_NOTIFICATIONS")
  .then((res) => {
    LOG("permission for notification enabled");
  })
  .catch((err) => {
    LOG("permission for notification canceled :", err);
  });`

I am using this const status = await PermissionsAndroid.request( PermissionsAndroid.PERMISSIONS.POST_NOTIFICATION, ); But it works fine on my emulator but it never asks for permission on a real device and the by default status consoles out as never_ask_again without even asking for permission. Maybe there is a conflict for the Android Version? If yes please guide me on how can I tackle it.

But there is another thing if I handleListeners for push notifications with permission status as never_ask_again and I send a notification from testfcm.com when the app is not active it works but is not in the active state for the first time.
