前言

最近搞了个设备，需求是读取m1卡，厂家给了个安卓原生demo，接入arr插件如下，接入后发现还是少了一部分代码，设备服务调起后触发刷卡无法发送到uniapp里。
中间是一些踩坑记录，最后面是解决办法，赶时间直接拉到最后

安卓原生广播

demo中的NfcService其中有一个onDataReceived方法，最终调用了LocalBroadcastManager 发送广播

protected void onDataReceived(final ComBean ComRecData) {Log.d(TAG, "发送消息！");LocalBroadcastManager localBroadcastManager = LocalBroadcastManager.getInstance(getApplicationContext());Intent intent = new Intent(NfcAction.ACTION_NOTIFY_CARD_NUMBER);intent.putExtra(NfcAction.KEY_NOTIFY_DECIMAL_CARD_NUMBER, decimal);intent.putExtra(NfcAction.KEY_NOTIFY_DECIMAL_REVERSE_CARD_NUMBER, decimalReverse);intent.putExtra(NfcAction.KEY_NOTIFY_ORIGINAL_CARD_NUMBER, originHex);intent.putExtra(NfcAction.KEY_NOTIFY_EIGHT_HEX_CARD_NUMBER, eightHex);intent.putExtra(NfcAction.KEY_NOTIFY_EIGHT_HEX_REVERSE_CARD_NUMBER, eightHexReverse);intent.addFlags(Intent.FLAG_RECEIVER_FOREGROUND);localBroadcastManager.sendBroadcast(intent);Log.d(TAG, "发送消息成功！");
}

在MainActivity的onCreate里有接收广播

val nfcCardReceiver = NfcCardReceiver()
val intentFilter = IntentFilter()
intentFilter.addAction(NfcAction.ACTION_NOTIFY_CARD_NUMBER)
LocalBroadcastManager.getInstance(this).registerReceiver(nfcCardReceiver, intentFilter)

NfcCardReceiver类

package com.rt.nfclibdemoimport android.content.BroadcastReceiver
import android.content.Context
import android.content.Intent
import android.util.Log
import com.rt.lib_nfc.NfcAction
import org.greenrobot.eventbus.EventBusclass NfcCardReceiver: BroadcastReceiver() {override fun onReceive(p0: Context?, p1: Intent?) {if (p1 != null) {val card = p1.getStringExtra(NfcAction.KEY_NOTIFY_ORIGINAL_CARD_NUMBER)val card2 = p1.getStringExtra(NfcAction.KEY_NOTIFY_DECIMAL_CARD_NUMBER)val card3 = p1.getStringExtra(NfcAction.KEY_NOTIFY_DECIMAL_REVERSE_CARD_NUMBER)val card4 = p1.getStringExtra(NfcAction.KEY_NOTIFY_EIGHT_HEX_CARD_NUMBER)val card5 = p1.getStringExtra(NfcAction.KEY_NOTIFY_EIGHT_HEX_REVERSE_CARD_NUMBER)//跟ui绑定的东西，忽略掉EventBus.getDefault().post(CardBean(card!!, card2!!, card3!!, card4!!, card5!!))Log.e("TAG", "onReceive: " + card + "---" + card2 + "---" + card3 + "---" + card4 + "---" + card5)}}
}

根据以往的经验写出如下代码，结果是失败的

const mainActivity = plus.android.runtimeMainActivity();
const NfcAction = plus.android.importClass('com.rt.lib_nfc.NfcAction');
var nfcCardReceiver = plus.android.implements('io.dcloud.android.content.BroadcastReceiver', {onReceive: function(context, intent) { //实现onReceiver回调函数plus.android.importClass(intent);console.log('context, intent ->', context, intent);console.log('intent.getAction() ->', intent.getAction());}
const IntentFilter = plus.android.importClass('android.content.IntentFilter');
const filter = new IntentFilter();
filter.addAction(NfcAction.ACTION_NOTIFY_CARD_NUMBER); //监听
let LocalBroadcastManager = plus.android.importClass('androidx.localbroadcastmanager.content.LocalBroadcastManager');
let localBroadcastManager = LocalBroadcastManager.getInstance(mainActivity);
localBroadcastManager.registerReceiver(nfcCardReceiver, filter);

最终结果是控制台无输出，
adb shell catlog抓到的日志是个null
在这里插入图片描述找了很久很久后，找到了个栗子，据说绑定不成功的原因是io.dcloud.android.content.BroadcastReceiver这个东西是抽象类，无法实现，只能用io.dcloud.feature.internal.reflect.BroadcastReceiver然而替换后还是不行，就是无法监听LocalBroadcastManager，又找了很久资料，找了无数篇垃圾文章后，找了原生安卓的很多文章后，终于找到了个办法，不用LocalBroadcastManager使用另一种方法发送，接收广播

最终方案

不使用LocalBroadcastManager发生监听广播
使用getApplicationContext().sendBroadcast(intent);发送广播
使用mainActivity.registerReceiver(nfcCardReceiver, filter);监听广播
首先将NfcService->onDataReceived改造，在原有基础上增加，更改后记得重新打成arr，然后重打自定义基座才能生效

protected void onDataReceived(final ComBean ComRecData) {Log.d(TAG, "发送消息！");LocalBroadcastManager localBroadcastManager = LocalBroadcastManager.getInstance(getApplicationContext());Intent intent = new Intent(NfcAction.ACTION_NOTIFY_CARD_NUMBER);intent.putExtra(NfcAction.KEY_NOTIFY_DECIMAL_CARD_NUMBER, decimal);intent.putExtra(NfcAction.KEY_NOTIFY_DECIMAL_REVERSE_CARD_NUMBER, decimalReverse);intent.putExtra(NfcAction.KEY_NOTIFY_ORIGINAL_CARD_NUMBER, originHex);intent.putExtra(NfcAction.KEY_NOTIFY_EIGHT_HEX_CARD_NUMBER, eightHex);intent.putExtra(NfcAction.KEY_NOTIFY_EIGHT_HEX_REVERSE_CARD_NUMBER, eightHexReverse);intent.addFlags(Intent.FLAG_RECEIVER_FOREGROUND);Log.d(TAG, "发送localBroadcastManager消息");//原来的发送广播语句//localBroadcastManager.sendBroadcast(intent);Log.d(TAG, "发送getApplicationContext消息");//新增的关键语句getApplicationContext().sendBroadcast(intent);Log.d(TAG, "发送消息成功！");
}

uniapp部分

registerReceiver(){const that = this;const Log = plus.android.importClass('android.util.Log');Log.d('NfcApp', '1');const mainActivity = plus.android.runtimeMainActivity();const NfcAction = plus.android.importClass('com.rt.lib_nfc.NfcAction');const nfcCardReceiverFunc = {  onReceive: function(context, intent) { //实现onReceiver回调函数  plus.android.importClass(intent);console.log('context, intent ->', context, intent);console.log('intent.getAction() ->', intent.getAction());console.log('回调成功！');that.cardData = {};let card1 = intent.getStringExtra(NfcAction.KEY_NOTIFY_ORIGINAL_CARD_NUMBER);let card2 = intent.getStringExtra(NfcAction.KEY_NOTIFY_DECIMAL_CARD_NUMBER);let card3 = intent.getStringExtra(NfcAction.KEY_NOTIFY_DECIMAL_REVERSE_CARD_NUMBER);let card4 = intent.getStringExtra(NfcAction.KEY_NOTIFY_EIGHT_HEX_CARD_NUMBER);let card5 = intent.getStringExtra(NfcAction.KEY_NOTIFY_EIGHT_HEX_REVERSE_CARD_NUMBER);console.log('返回数据->',card1, card2, card3, card4, card5);if(card1 == 'AABB0600000001060007'){return;}//最终返回的数据that.cardData = { card1, card2, card3, card4, card5 };}};const nfcCardReceiver = plus.android.implements('io.dcloud.feature.internal.reflect.BroadcastReceiver', nfcCardReceiverFunc);const IntentFilter = plus.android.importClass('android.content.IntentFilter');const filter = new IntentFilter();Log.d('NfcApp', '2');filter.addAction(NfcAction.ACTION_NOTIFY_CARD_NUMBER); //监听Log.d('NfcApp', '3');let res = mainActivity.registerReceiver(nfcCardReceiver, filter);Log.d('NfcApp', '4');Log.d('NfcApp', '绑定成功？？？')//解除绑定，暂未实现//unregisterReceiver
