隨著國(guó)家2035年計(jì)劃的提出，以及國(guó)家十三五規(guī)劃等全面的提出信息安全被提升到國(guó)家安全的層面，工業(yè)領(lǐng)域的發(fā)展更是提高到新的高度，搭載Android系統(tǒng)的設(shè)備被廣泛用于電力行業(yè)、石油石化行業(yè)軌道交通及先進(jìn)制造業(yè)。目前，市面上支持Android系統(tǒng)的智能卡讀寫器還是比較少，有部分采用串口通信的IC卡讀寫，在與Android設(shè)備進(jìn)行接入和二次開發(fā)過程中非常不方便。因此，諾塔斯智能科技有限公司早在2013年就推出了基于Android系統(tǒng)免驅(qū)的USB 和串口，藍(lán)牙，WIFI、RJ45有線網(wǎng)絡(luò)等多種通信方式的智能卡讀寫器。
以下內(nèi)容是針對(duì)諾塔斯L3-U非接觸式IC卡讀寫器在Android系統(tǒng)中的二次開發(fā)范例說明，其它型號(hào)的智能卡讀寫器在Android系統(tǒng)中的二次開發(fā)，大致相同，修改設(shè)備初始化參數(shù)即可，具體可以在開發(fā)過程中咨詢技術(shù)支持。
首先，需要Android設(shè)備支持USB HOST或者OTG通信，在AndroidManifest.xml文件中進(jìn)行USB權(quán)限配置。
Android配置文件要求
在你使用以上API進(jìn)行開發(fā)之前，你需要在你的AndroidManifest.xml文件中添加以下內(nèi)容：
1.因?yàn)椴⒉荒鼙ＷC所有的安卓設(shè)備都支持以上API，所以你需要聲明：
<uses-sdk android:minSdkVersion="12" />12以下的版本是不支持以上APId的。
<uses-feature android:name="android.hardware.usb.host" />
2.如果你想有一個(gè)USB設(shè)備接入你的安卓設(shè)備時(shí)能夠通知你的應(yīng)用程序，那么你需要在你的Activity標(biāo)簽中聲明以下內(nèi)容
<intent-filter>
<action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
</intent-filter>
<meta-data android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" android:resource="@xml/device_filter" />
Resource屬性指定了要過濾的數(shù)據(jù)設(shè)備信息，包括：
1) vendor-id 設(shè)備生產(chǎn)商id
2) product-id 設(shè)備id
3) class 設(shè)備類別
4) subclass 設(shè)備子類
5) protocol(device or interface) 協(xié)議類別
device_filter.xml文件放在res\xml目錄下，其中文件名不包括擴(kuò)展名部分需要與<meta-data/> 標(biāo)簽中聲明的一致。示例如下：
<?xml version="1.0" encoding="utf-8"?>
<resources>
<usb-device vendor-id="1234" product-id="5678" class="255" subclass="66" protocol="1" />
</resources>
開發(fā)步驟
1、在Android開發(fā)工程文件夾libs文件夾中導(dǎo)入外部.so庫(kù)文件，我們?yōu)榭蛻籼峁┝硕喾N平臺(tái)的庫(kù)。包括，arm64-v8a、armeabi、armeabi-v7a、mips、mips64、x86、x86_64等，具體可以參考Android IC卡讀寫器二次開發(fā)范例。
2、定義關(guān)鍵參數(shù)，以ISO14443 A卡為例，定義相關(guān)參數(shù)如下：
package cc.lotuscard;
public class LotusCardParam {
public LotusCardParam()
{
arrCardNo = new byte[8];
arrBuffer = new byte[64];
arrKeys = new byte[64];
arrCosResultBuffer = new byte[256];
arrCosSendBuffer = new byte[256];
}
/**
* 卡片類型
*/
public int nCardType;
/**
* 8字節(jié)卡號(hào)
*/
public byte[] arrCardNo;
/**
* 卡片容量大小
*/
public int nCardSize;
/**
* 讀寫緩沖
*/
public byte[] arrBuffer;
/**
* 緩沖大小
*/
public int nBufferSize;
/**
* 密鑰
*/
public byte[] arrKeys;
/**
* KEYs大小
*
*/
public int nKeysSize;
/**
* pCosResultBuffer COS執(zhí)行結(jié)果緩沖
*/
public byte[] arrCosResultBuffer;
/**
* unCosReultBufferLength COS執(zhí)行結(jié)果緩沖長(zhǎng)度
*/
public int unCosReultBufferLength;
/**
* pCosSendBuffer COS指令發(fā)送緩沖
*/
public byte[] arrCosSendBuffer;
/**
* unCosSendBufferLength COS指令發(fā)送緩沖長(zhǎng)度
*/
public int unCosSendBufferLength;
}
注意：包名必須按照 package cc.lotuscard;這種格式。
