uniapp Native.js 调用安卓arr原生service

最近搞了个uni小项目，一个定制的小平板，带一个nfc设备，厂家只给了一套安卓原生demo，头一次玩原生安卓，废了好半天劲打出来arr包，想镶进uniapp里，网上查了好久，都是错的，要么无法运行，要么运行了没反应，要么编译都过不去。。。官网给的示例更是没有示例，主打一个用法全靠猜。。。

服务

厂家给了个NfcService 里面是继承自标准android.app.Service另一部分是个androidx.appcompat.app.AppCompatActivity页面，里面启动，调用的NfcService

java部分`NfcService`核心代码

private val connection = object : ServiceConnection {override fun onServiceConnected(p0: ComponentName?, p1: IBinder?) {Log.e(TAG, "onServiceConnected: ")nfcBinder = p1 as NfcService.MyBindernfcBinder?.openPort(model)}override fun onServiceDisconnected(p0: ComponentName?) {Log.e(TAG, "onServiceDisconnected: ")nfcBinder = null}
}override fun onCreate(savedInstanceState: Bundle?) {//无关代码太多，就不粘了//绑定服务bindService(Intent(this, NfcService::class.java), connection, Context.BIND_AUTO_CREATE)//一定条件后，解绑服务unbindService(connection)
}

从没接触过安卓原生，一下子就麻了，不知道在uni那边怎么用，找了半天找到了这个

uniapp的一个页面

//开启服务（无回值启动）二选一
startAppService(){const mainActivity = plus.android.runtimeMainActivity();const Context = plus.android.importClass('android.content.Context');const Intent = plus.android.importClass('android.content.Intent');const intent = new Intent();intent.setClassName(mainActivity, 'com.rt.lib_nfc.NfcService');const Bundle = plus.android.importClass('android.os.Bundle');var bundle = new Bundle();intent.putExtras(bundle);mainActivity.startForegroundService(intent)
},
//绑定服务（有回值启动）二选一
bindAppService(){const that = this;const main = plus.android.runtimeMainActivity();const Context = plus.android.importClass('android.content.Context');const Service = plus.android.importClass('android.app.Service');const Intent = plus.android.importClass('android.content.Intent');let serviceConnectionFunc = {onServiceConnected: function(name, service) {console.log("服务已连接", name, service);//service.openPort('READ');that.nfcService = service;},onServiceDisconnected: function(name) {console.log("服务已断开", name);that.nfcService = null;}};let serviceConnection = plus.android.implements('android.content.ServiceConnection', serviceConnectionFunc);const intent = new Intent();intent.setClassName(main, 'com.rt.lib_nfc.NfcService');main.bindService(intent, serviceConnection, Service.BIND_AUTO_CREATE);
},
//最终使用
testService(){let res = this.nfcService?.openPort('get');console.log('res ->', res);
}
