使用“-prod”构建运行时，Ionic 应用程序在启动画面处停止

【中文标题】使用“-prod”构建运行时，Ionic 应用程序在启动画面处停止【英文标题】：Ionic app halts at splash screen when running with ‘–prod’ build 【发布时间】：2018-08-19 09:42:56 【问题描述】：我一直在开发一个包含“应用内购买”、“firebase 动态链接”等的应用。当我使用命令运行该应用时，该应用在 android 和 ios 上都能正常运行：
ionic cordova run android
ionic cordova build ios
但是，一旦我在他们面前使用“--prod”运行应用程序，该应用程序就会卡在我的启动屏幕/app.component.ts 屏幕上。
我的一些应用程序的结构如下所示：

我的 chrome 检查器向我显示了此日志（仅在开发模式下，顺便说一下我的应用正在处理此日志 - 这仅供您参考）
我应该如何进行？
【问题讨论】：
【参考方案1】：你想在什么安卓版本上运行它？ 我问这个是因为 Ionic 3 不支持所有 android 版本。根据我的经验，4.4 及更高版本可以运行良好，但较低版本有这种问题。
另外，在开始执行 --prod 和 --release 之前清理（删除文件）在 platform/android/app/build/outputs/apk/release 和 platform/android/app/build/outputs/apk/debug 下
比运行你的 --prod 或 --release
【讨论】：
我在 Android 6.0 版上运行它，我已经完成了您提到的所有操作，但我的应用程序仍然无法在这两个平台上运行。感谢回复 你可以尝试将这个：<preference name="SplashScreenDelay" value="2000"/> <preference name="FadeSplashScreenDuration" value="2000"/> <preference name="SplashScreen" value="screen"/> <preference name="ShowSplashScreenSpinner" value="false"/> <preference name="AutoHideSplashScreen" value="false" /> 添加到你的 config.xml以上是关于使用“-prod”构建运行时，Ionic 应用程序在启动画面处停止的主要内容，如果未能解决你的问题，请参考以下文章
Ionic 3 - 应用程序在使用 --prod 构建后显示空白屏幕但使用开发模式
ionic cordova build --prod --release 失败并产生错误
Ionic 3 - 使用 --prod 标志运行时，sqlite 显示“无法读取 openDatabase 的属性”的错误
