Ionic Release APK每次构建都会增加文件大小

Question

我是 Ionic 的新手，并且编写了我的第一个Android应用程序。

没有安装额外的软件包/库，只有一页不太重。

当我构建第一个版本时

cordova build android --prod --release

生成的文件大小为 3.x mb 我添加了一个较小的更改并生成了一个新版本，但是这次文件大小为 7.x mb

这是我的 package.json

以及仅首页 home.page.ts

的内容

import { Component, OnInit } from '@angular/core';
import { FormGroup, FormBuilder, FormControl, Validators } from '@angular/forms';
import {Platform} from '@ionic/angular';
import {Subscription} from 'rxjs';

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

    public phoneNumber: string;
    public errorMessage: string | null;

    public inputForm: FormGroup;
    private subscription: Subscription;

    constructor(
        private fb: FormBuilder,
        private platform: Platform
    ) {}

    ngOnInit() {
        this.inputForm = this.fb.group({
            phoneNumber: new FormControl('', [
                Validators.required
            ])
        });
    }

    ionViewDidEnter() {
        this.subscription = this.platform.backButton.subscribe(() => {
            navigator['app'].exitApp();
        });
    }

    ionViewWillLeave() {
        this.subscription.unsubscribe();
    }

    start() {
        let phoneNumber = this.inputForm.value['phoneNumber'];

        if (!phoneNumber) {
            this.errorMessage = 'Phone number required';
            return;
        }

        // Remove white spaces and +
        phoneNumber = phoneNumber.replace(/\s/g, '').replace('+', '');

        const url = this.web + phoneNumber;

        window.open(url, '_system', 'location=yes');
    }
}

这仅是文件大小仍超过7 mb的内容。
