如何使用sdk创建cordova插件

Question

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（cordova-lib@8.1.1）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Plugin.xml

<?xml version='1.0' encoding='utf-8'?>

这是我的js文件。 chirp.js：

var exec = require('cordova/exec');

var chirp ={
  getPermissions:function(message){
    console.log(message);
    exec(null, null, 'Chirp', 'getPermissions', [message]);
  },
  start:function(message){
    console.log(message);
    exec(null, null, 'Chirp', 'start', [message]);
  },
  send:function(message){
    console.log(message);
    exec(null, null, 'Chirp', 'send', [message]);
  }
};

module.exports = chirp

这是我的gradle文件。 chirp.gradle：

repositories {
  jcenter()
  flatDir {
    dirs 'libs'
  }
}

dependencies {
   compile(name:'chirp-connect-release', ext:'aar')
}

android {
    packagingOptions {
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
    }
}
