Question

Добрый день, на самом деле у меня проблемы с моим кодом, когда я обращаюсь к тегу NFC к мобильному телефону, поддерживающему NFC, вместо моего приложения отображается «Службы NFC».

Я пришел к выводу, что это может быть AndroidManifest.xml, но я уже изменил его, чтобы получать события MIME из фильтра намерений, вот код:

app.component.ts

import firebase from 'firebase';

import { Component, ViewChild } from '@angular/core';
import {Keyboard} from '@ionic-native/keyboard';
import { Platform, Nav, App, AlertController} from 'ionic-angular';
import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';
import { WelcomePage } from '../pages/welcome/welcome';
import { LoginPage } from '../pages/login/login';
import { PpPage } from '../pages/menu/pago/pp/pp';
import { NosotrosPage } from '../pages/menu/nosotros/nosotros';
import { ConfigPage } from '../pages/menu/config/pp/config';
import { SavlistPage } from '../pages/savlist/savlist';
import { AuthService } from '../services/auth';
import { MenuController } from 'ionic-angular';
import { InicioPage } from '../pages/inicio/inicio';
import { Observable } from 'rxjs';
import { AngularFireDatabase } from 'angularfire2/database';
import { Toast } from '@ionic-native/toast';
import { NFC } from '@ionic-native/nfc';
import { window } from 'rxjs/operator/window';
import { Message } from '@angular/compiler/src/i18n/i18n_ast';

@Component({
  templateUrl: 'app.html'
})


export class MyApp {
  @ViewChild(Nav) nav:Nav;

  rootPage: any = WelcomePage;
  rootPageParams: any;


  loginPage: LoginPage;
  users: Observable<any>;
  usdata: any = "npc";
  name: string;
  showSplash = true;
  isAthenticated = false;

  constructor(platform: Platform, statusBar: StatusBar, 
    splashScreen: SplashScreen,
    private menuCtrl: MenuController,
    private authService: AuthService,

    private app: App,
    private alrtCtrl: AlertController,
    private toast: Toast,
    public keyboard: Keyboard,
    public nfc: NFC)
    {

    if (!firebase.apps.length)
    { 
      firebase.initializeApp({
        apiKey: "XXXXXX",
        authDomain: "XXXXXXXX",
        databaseURL: "XXXXXXXX",
        projectId: "XXXXXX",
        storageBucket: "XXXXXX",
        messagingSenderId: "XXXXXXXX"
      });
  }


    firebase.auth().onAuthStateChanged( user => {

      if(user)
      {

        this.isAthenticated = true;
        this.rootPage = InicioPage;

        this.nfc.addNdefListener().subscribe((data)=>{
          console.log(data)
        });

        this.nfc.addMimeTypeListener('text/plain').subscribe((data)=>{
          console.log(data)
        });




        try
        {
          this.usdata = firebase.auth().currentUser.email;
        }
        catch(e)
        {
          console.log("No ha iniciado sesion");
        }

        this.users = this.af.object("/users").valueChanges();

        this.users.subscribe(data => {

                    for (let p in data)
                    { 

            let value = data[p];

            if (value.correo_u == this.usdata)
            {
              this.name = value.name_u;
            }


                    }
        });        

    }
      else
      {
        this.nfc.addNdefListener().subscribe((data)=>{
          let payload = data.tag.ndefMessage[0].payload;
          let tagContent = this.nfc.bytesToString(payload).substring(3);
          console.log(data)
          this.alrtCtrl.create({
            message: tagContent,
          }).present();
        });

        this.nfc.addMimeTypeListener('text/plain').subscribe((data)=>{
          console.log(data)
          this.alrtCtrl.create({
            message: data,
          }).present();
        });

        this.isAthenticated = false;
        this.rootPage = WelcomePage;
      }
    });


    platform.ready().then(() => {
      statusBar.styleDefault();
      splashScreen.hide();



      this.keyboard.disableScroll(true);


       });


    platform.registerBackButtonAction(() => {
      // Catches the active view
      let nav = app.getActiveNav();
      let activeView = nav.getActive();    

      // Checks if can go back before show up the alert
      if (activeView.name == 'InicioPage')
      {
        platform.exitApp();
      }

      if (activeView.name == 'WelcomePage')
      {
        platform.exitApp();
      }

      if(activeView.name == 'ListsPage') 
      {
        activeView.instance.volver();
      }
      else
      {
        activeView.dismiss();
      }
    });

}

и вот что он показывает:
