ionic build android 慢,解决ionic安卓启动慢及白屏问题

ionic3在安卓平台上启动慢导致用户体验不好 以下方法可缩减启动时间

修改app.component.ts

declare const window: any;

@Component({

templateUrl: 'app.html'

})

export class MyApp {

rootPage:any = 'TabsPage';

constructor(platform: Platform, statusBar: StatusBar, splashScreen: SplashScreen) {

if (window.cordova) {

document.addEventListener("deviceready", () => {

// retrieve the DOM element that had the ng-app attribute

statusBar.styleLightContent();

//延迟隐藏闪屏 防止有白屏

window.setTimeout(() => {

splashScreen.hide();

}, 500);

// 代码开始

if (platform.is("ios")) {

console.log('this is ios');

} else if (platform.is("android")) {

console.log('this is android');

}

}, false);

} else {

console.log('web 模式');

// 代码开始

}

}

}

打包

ionic cordova build android --prod --release

最终启动时间大概在3秒左右，根据项目而定。
