【问题描述】：
我的 ionic2 应用需要大约 15 秒才能在设备中启动。我尝试了所有建议（minify、uglify、enableProd、--prod --release 等） 我的最终 apk 是 4.3MB
该应用程序除了图标和启动画面外没有任何图像，它有更少的 20 个屏幕，但只有文本、列表和按钮（这是一个支付应用程序，所以没什么奇怪的）
我的 package.json 是：

您是否发现依赖项或插件有任何问题？
最小化的 main.js 文件为 5.8MB。

有什么建议吗？你需要更多信息？这是我在 Ionic2 中的第一个应用程序，加载 15 秒是不可接受的。请帮助找到解决方案，我在这个应用程序上投入了大量时间。

我也面临同样的问题。等待 ionic 团队发布更新的优化版本。他们正在努力。

您有更多信息的链接吗？无论如何，有几页有建议（这对我不起作用）但可能是 ionic 2.2.1 的问题？你试过低版本吗？
