Ionic firebase token alway null and no token refre

问题:

i'm in trouble with ionic firebase module (https://ionicframework.com/docs/native/firebase/) during the last 2 days.

I don't understand why my firebase token is alway NULL in the following code section in app.component.ts :

this.platform.ready().then(() => {
  this.firebase.getToken().then(firebaseTokenSuccess).catch(firebaseTokenFailure);

  this.firebase.onTokenRefresh().subscribe(firebaseTokenRefresh);

  function firebaseTokenRefresh(tkn) {
    return alert("New token received: " + JSON.stringify(tkn));
  }

  function firebaseTokenSuccess(tkn) {
    return alert("Token access success: " + JSON.stringify(tkn));
  }

  function firebaseTokenFailure(e) {
    return alert("Token access failure: " + e.toString());
  }
});

If i had grantPermission() at the beggining of the ready block my token become an empty string

I ran the following command to install my plugin :

$ ionic plugin rm cordova-plugin-firebase

$ npm install @ionic-native/push --save

Here is the list of my plugins :

$ ionic plugins                        
com.googlemaps.ios 2.4.0 "Google Maps SDK for iOS"

try is code in ionic 2

import { Platform } from 'ionic-angular';
import { Firebase } from '@ionic-native/firebase';

 constructor(public platform: Platform,private cordovaFirebase: Firebase)   {
  platform.ready().then(() => {
    StatusBar.styleDefault();
    Splashscreen.hide();
    this.cordovaFirebase.grantPermission();
    this.cordovaFirebase.getToken().then(token => {
       console.log("token....",token)
    }).catch(error => console.log(error)); 
  });
 }

The cordova-pugin-firebase is broken in cordova ver:7.0.0

Use any of the following methods for fixing it.

https://github.com/arnesson/cordova-plugin-firebase/pull/570

Installation command for cordova android version 7 and above:

cordova plugin add cordova-plugin-firebase --variable ANDROID_VERSION=7x --save

Installation command for cordova android version 6 and below:

cordova plugin add cordova-plugin-firebase --variable ANDROID_VERSION=6x --save

or

https://github.com/arnesson/cordova-plugin-firebase/issues/558

Update the stringsXml in the following files:

plugins/cordova-plugin-firebase/scripts/after_prepare.js line 51 node_modules/cordova-plugin-firebase/scripts/after_prepare.js line 51

-       stringsXml: ANDROID_DIR + '/res/values/strings.xml' 
+       stringsXml: fileExists(ANDROID_DIR + '/app/src/main/res/values/strings.xml') ? ANDROID_DIR + '/app/src/main/res/values/strings.xml' : ANDROID_DIR + '/res/values/strings.xml'
