我正在研究离子2。当应用程序运行时，在启动页面之后，我面对白屏，这需要10秒以上，然后将显示我的主页。有什么办法可以避免这种情况吗？

将 splasscreendelay 值设置为 20000 并删除自动隐藏闪屏首选项。隐藏平台上的初始屏幕，准备好在 app.component.ts 中。在你的app.component.ts
import { SplashScreen } from '@ionic-native/splash-screen';
import { Platform} from 'ionic-angular';
constructor(splashScreen: SplashScreen,platform: Platform){
platform.ready().then(() => {
splashScreen.hide();
});
}
在制作构建时，您必须使用--prod。
ionic build android --prod
或
ionic cordova build android --prod
