android - 在 Android 设备中运行 IONIC 2 应用程序时出现问题

Question

我在我的 config.xml 文件中添加了以下行。

<preference name="loadUrlTimeoutValue" value="700000"/>

当我使用 ionic run android -l -c 在 android 设备中运行应用程序时，它在加载初始屏幕后显示白色屏幕一段时间。我该如何解决这个问题？

这里是我的 app.component.ts 文件，

import { Component } from '@angular/core';
import { Platform } from 'ionic-angular';
import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';
import { Geolocation } from '@ionic-native/geolocation';
import { AdMob, AdMobOptions, AdSize, AdExtras} from '@ionic-
native/admob';//import


import { HomePage } from '../pages/home/home';
import { DetailsPage } from '../pages/details/details';
import { SettingModalPage } from '..Pages/setting-modal/setting-modal';


@Component({
templateUrl: 'app.html'
})
export class MyApp {
rootPage:any = HomePage;

constructor(platform: Platform, statusBar: StatusBar, splashScreen: SplashScreen, admob: AdMob) {
  platform.ready().then(() => {
  // Okay, so the platform is ready and our plugins are available.
  // Here you can do any higher level native things you might need.
  statusBar.styleDefault();
  splashScreen.hide();

let options:AdMobOptions={
adId: 'ca-app-pub-5732334124058455/7973166445',
adSize: 'SMART_BANNER',
isTesting: false
 }

admob.createBanner(options).then(()=>{
   admob.showBanner(8)
 })

});
}
}

我的config.xml文件代码，

Answer 1

更新:

我认为您唯一的解决方案是删除 AdMob来自你的依赖 app.component.ts文件并在您需要使用它的页面组件上实现它。您必须设置 LoadUrlTimeoutValue默认像 <preference name="LoadUrlTimeoutValue" value="20000"/> .

旧答案

备份您的 config.xml文件并执行以下更改并查看。

删除 config.xml 中的以下 2 行文件。

  <preference name="SplashScreen" value="screen"/>
  <preference name="SplashScreenDelay" value="3000"/>
