[Android] Can't use Capacitor plugin Push Notifications

[TayKara]

Description of the problem: I can't use Push Notifications plugin, it causes error in execution. The only thing I did was to create an Ionic project (ionic start testNotifications blank --capacitor), init cap, and modified home.page.ts and then build/open in android studio.

In home.page.ts :

import { Component, OnInit } from '@angular/core'; import { Plugins } from '@capacitor/core';

const { PushNotifications } = Plugins; @Component({ selector: 'app-home', templateUrl: 'home.page.html', styleUrls: ['home.page.scss'], }) export class HomePage implements OnInit {

ngOnInit(): void { PushNotifications.register(); }

}

The error I have in Android Studio (when executing in my phone (Honor 9 Lite - Android 8.0.0) connected by USB in debug mode :

OS of the development machine

Did you add the google-services.json file to your app?

[TayKara]

It was indeed the problem ! I putted my google-services.json file in the wrong directory. For the ones who want to know, google-services.json file has to be add in ./android/app/ and the package name of your project has to be the same as the package name in your google-services.json

EDIT : I no longer have an error, but I can't register. Nothing is happening when I do :

PushNotifications.register();
PushNotifications.addListener('registration', (token: PushNotificationToken) => {
  console.log('token ' + token.value);
});

EDIT 2 : forgot to activate wifi, forgive my idiocy...

Many thanks @jcesarmobile ! :)

You need to add google-services.json file to yourapp/android/app/ not simply to yourapp/
