[messaging] requestPermissions on Android 13

[fpaaske]

I'm running into issues with requestPermission on Android 13.

in app.gradle

targetSdkVersion 33

in manifest

<uses-permission android:name="android.permission.POST_NOTIFICATIONS"/>

in package.json

deps
    "@nativescript/angular": "~14.2.0",
    "@nativescript/core": "~8.3.5",
    "@nativescript/firebase-core": "^2.4.4",
    "@nativescript/firebase-crashlytics": "^2.4.4",
    "@nativescript/firebase-messaging": "^2.4.4",

dev-deps
    "@nativescript/android": "8.3.1",
    "@nativescript/ios": "8.3.3",
    "@nativescript/types": "~8.3.1",

---

I have this code:

main.ts

import {firebase} from '@nativescript/firebase-core';
import '@nativescript/firebase-messaging';
import '@nativescript/firebase-crashlytics';

---

some.service.ts

constructor()
    firebase().initializeApp()
      .then(firebaseApp => {
        const messaging = firebase().messaging();
        messaging.onMessage(this.onMessage);
        messaging.onNotificationTap(this.onNotificationTap);
      })
      .catch(error => this.loggerService.error('Firebase::Failed to initialize', error));

In another method:

registerToken()
    const messaging = firebase().messaging();
    messaging.requestPermission({ios: iosPermissions}).then(authStatus => {
      const granted = authStatus === AuthorizationStatus.AUTHORIZED || authStatus === AuthorizationStatus.PROVISIONAL;
      if (granted) {
        messaging.registerDeviceForRemoteMessages()
          .then(result => {
            messaging.getToken().then(token => this.storeToken(token));
            messaging.onToken(this.onTokenCallback);
          })
          .catch(error => this.loggerService.error('register failed', error));
      }
    }).catch(error => this.loggerService.error('request permission failed', error));

---

Then I have "some.component.ts" using the "some.service.ts", and I get this error

request permission failed Error: Cannot assign primitive value to array of objects.
  at requestPermission (file: src/webpack:/my-app/node_modules/@nativescript/firebase-messaging-core/index.android.js:258:0)
  ...

It points to this code (index.android.js:258:0):

const perms = Array.create('java.lang.String', 1);
perms[0] = android.Manifest.permission.POST_NOTIFICATIONS; // line 258
activity.requestPermissions(perms, 1001);

This is working fine in earlier Android versions. (also without the app.gradle and manifest changes).
Any tips on how to solve this?

I checked two other cases #125 and #144, but they seemed to have other issues.

HI,

Did you tried to delayed the permission request with settimeout() maybe you request permission too early !?

[fpaaske]

Thanks for the tip, @kefahB, but even adding a 5 second delay did not make any difference.

It seems like the issue is the type of android.Manifest.permission.POST_NOTIFICATIONS. Maybe some of my dependencies or configurations are incorrect?

Did you installed SDK 33 ? if not begin with this first and then if it doesn't work try to set compileSdkVersion 33 at app.gradle

[fpaaske]

I had already installed SDK 33, but compileSdk 33 in app.gradle was the key. It works now, thanks!
