Oracle JET：为 android 启动 ojet 混合应用程序时出错

【问题标题】：Oracle JET: Getting error while launching ojet hybrid app for androidOracle JET：为 android 启动 ojet 混合应用程序时出错
【发布时间】：2020-08-26 06:06:02
【问题描述】：

当我们启动一个简单的应用程序时，Android 模拟器显示错误，请参阅随附的屏幕截图。 它在 iOS 上按预期工作。

我已经尝试了所有的默认模板导航栏、导航抽屉和空白。

这是一个直接来自入门页面的应用程序，没有对模板代码进行任何修改。

标签： oracle-jet


【解决方案1】：

无需为您的应用添加额外的插件。 您只需将此行添加到您的 AndroidManifest.xml 文件中即可。 这应该只在开发过程中需要，因为一旦您使用 --release 发布应用程序，它将使用 https 而不会使用明文。

在标签内，添加

AndroidManifest.xml 文件默认位于

/hybrid/platforms/android/app/src/main

【讨论】：

    【解决方案2】：

    以下解决方案对我有用

    ojet add plugins cordova-plugin-cleartext
ojet build android
ojet serve android

    【讨论】：

      【解决方案3】：

      如果您正在阅读本文并且上述解决方案对您不起作用，您可以将这项工作应用到对我有用的范围内，请访问：

      /node_modules/@oracle/oraclejet-tooling/lib

      在 JS 文件的那个文件夹中：serveHybrid.js 搜索：（在我的例子中是第 42 行）：

      if (serveOptions.livereload) {
    serveWatch(serveOptions.watch, serveOptions.livereloadPort);

      添加为serveWatch的参数，serveOptions：

      serveWatch(serveOptions.watch, serveOptions.livereloadPort, serveOptions);

      这对我很有用，可以解决 liveReload 问题。

      问候。
