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 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
},重新打包重新运行后即可接到this.cardData返回的值了
