我目前正在开发一个使用Ionic/Cordova开发Android应用的项目。在这个应用程序中，我们需要使用EAP TTLS自动连接到wifi网络，为此我们正在开发一个cordova插件。
正如许多教程所示，我们通过创建一个完全符合我们想要的Android应用程序来开始开发。接下来，我们将其变成了一个插件。到目前为止，一切都很棒，我们实现了所需的功能，并将插件添加到Ionic项目中，没有错误。
现在，当我们执行命令ionic build时，我们会收到许多与插件中使用的导入相关的错误，例如：
import android.net.wifi.WifiConfiguration;
import android.net.wifi.WifiManager;
import android.net.wifi.WifiConfiguration;
import android.net.wifi.WifiEnterpriseConfig;
import android.net.wifi.WifiManager;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
从开发之前完成的所有研究中我们了解到，您可以直接为Android开发的任何应用都可以变成插件。因此，我认为我们错过了这个过程中的重要一步，或者采取了错误的方法来开发。
愿任何人帮我解决这个问题或者指出构建Ionic / Cordova插件的正确方法吗？

看来你正在创建一个Java动作，你需要创建一个简单的Java类，其中包含一些函数，允许你将该Java类转换为cordova的插件
在这里你可以找到如何创建一个简单的echo插件：
https://cordova.apache.org/docs/en/2.5.0/guide/plugin-development/android/
注意它扩展CordovaPlugIn，主函数是execute，带有3个参数
