我有一个离子3应用程序，我需要添加一个Android sdk。没有插件，所以我必须为它创建一个cordova插件。我现在尝试了几天，我可以获得安装和构建的插件，没有错误，但调用插件方法似乎没有做任何事情。我可以获取插件的js文件来输出console.logs，但java文件似乎根本没有运行。这是我项目的离子信息。我对java代码或cordova插件开发没有经验，所以我遇到了一个主要的障碍，因为我无法弄清楚为什么没有调用java代码。谁能看到我做错了什么？离子型：
离子（离子CLI）：4.4.0（/ usr / local / lib / node_modules / ionic）离子框架：离子角度3.9.2 @ ionic / app-scripts：3.2.0
科尔多瓦：
cordova（Cordova CLI）：8.1.2（[email protected]）Cordova平台：android 7.1.4，ios 4.5.5 Cordova插件：cordova-plugin-ionic-webview 1.2.1，（和其他31个插件）
系统：
ios-deploy：1.9.4 NodeJS：v10.7.0（/ usr / local / bin / node）npm：6.4.1 OS：macOS High Sierra Xcode：Xcode 10.1 Build版本10B61

这是我的js文件。 chirp.js：

我发现的一件事是你的插件Java文件的目标文件路径是错误的：
<source-file src="src/android/chirp.java" target-dir="src/org/apache/cordova/plugin/chirp" />
你的chirp类的包名是com.chirp.cordova.plugin所以target-dir应该是src/org/apache/cordova/plugin而不是src/org/apache/cordova/plugin/chirp，即：
<source-file src="src/android/chirp.java" target-dir="src/org/apache/cordova/plugin" />
请注意，value所需的<param name="android-package">实际上是完全限定的类名（而不是包名），因此名称android-package有点误导。因此，您目前拥有的是正确的：
<param name="android-package" value="org.apache.cordova.plugin.chirp" />
如果您正在开发Cordova插件，我建议您分别使用Android Studio和Xcode调试Android和iOS实现。
如果您在Android Studio中的测试工具应用程序中运行了插件，那么您会在logcat输出中看到一个警告，指示Cordova无法找到指定插件的本机实现。此外，您还可以使用Android Studio中的逐步调试器调试本机插件Java代码中的任何问题。
