摘要：通过导入开发包sdk开发基几Android NFC设备读取身份证信息
1. 开发条件：
1）鱼住往来科技的身份验证sdk ：下载地址：/views/service/index.html
2）Android Studio3.0以上
3）基于java语言开发，非kotlin语言
2.添加包步骤：
1）添加以下两个包
在Android Studio项目 中相应的依赖文件build.gradle（Module.app）添加包的依赖
文件：build.gradle（Module.app）:
PS:android 需要28 的sdk一下：
android {compileSdkVersion 28buildToolsVersion "30.0.1"defaultConfig {applicationId "com.example.id_test"minSdkVersion 26targetSdkVersion 28versionCode 1versionName "1.0"testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"ndk {abiFilters 'armeabi-v7a', 'arm64-v8a','x86', 'x86_64'}javaCompileOptions {annotationProcessorOptions {includeCompileClasspath = true}}}sourceSets {main {jniLibs.srcDirs = ['libs']}}repositories{flatDir{dirs 'libs'}}buildTypes {release {minifyEnabled falseproguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'}}}dependencies {implementation fileTree(dir: "libs", include: ["*.jar"])implementation(name:'yzwlnfcreadcard', ext:'aar')implementation 'androidx.appcompat:appcompat:1.1.0'implementation 'com.google.android.material:material:1.1.0'implementation 'androidx.constraintlayout:constraintlayout:1.1.3'implementation 'androidx.navigation:navigation-fragment:2.3.0'implementation 'androidx.navigation:navigation-ui:2.3.0'testImplementation 'junit:junit:4.12'androidTestImplementation 'androidx.test.ext:junit:1.1.1'androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'}
添加好相应的依赖后，gradle一下，就可以引用相应的包了
2）AndroidMainifest.xml 文件添加相应的权限：
<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="/apk/res/android"xmlns:tools="/tools"package="com.example.id_test"><uses-permission android:name="android.permission.NFC" /><uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" /><uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" /><uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /><uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.WAKE_LOCK" /><uses-permission android:name="android.permission.ACCESS_SUPERUSER" /><uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.WRITE_SETTINGS"tools:ignore="ProtectedPermissions"/><uses-permission android:name="android.permission.CAMERA"/><uses-permission android:name="android.hardware.camera" /><uses-permission android:name="android.hardware.camera.autofocus" /><uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.WAKE_LOCK" /><uses-permission android:name="android.permission.ACCESS_SUPERUSER" /><uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-featureandroid:name="android.hardware.nfc"android:required="true" /><applicationandroid:allowBackup="true"android:icon="@mipmap/ic_launcher"android:label="@string/app_name"android:roundIcon="@mipmap/ic_launcher_round"android:supportsRtl="true"android:theme="@style/AppTheme"><activityandroid:name=".MainActivity"android:label="@string/app_name"android:theme="@style/AppTheme.NoActionBar"><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter><intent-filter><action android:name="android.nfc.action.TECH_DISCOVERED" /></intent-filter><meta-dataandroid:name="android.nfc.action.TECH_DISCOVERED"android:resource="@xml/nfc_tech_filter" /></activity></application></manifest>
相应的资源文件：res/xmlnfc_tech_filter.xml——NFC过滤器文件：<resources xmlns:xliff="urn:oasis:names:tc:xliff:document:1.2"><tech-list><tech>android.nfc.tech.IsoDep</tech><tech>android.nfc.tech.MifareClassic</tech><tech>android.nfc.tech.NfcA</tech></tech-list><tech-list><tech>android.nfc.tech.IsoDep</tech><tech>android.nfc.tech.NfcB</tech><tech>android.nfc.tech.NfcA</tech></tech-list></resources>
注意：其中添加了一种NFC过滤器触发Intent——当NFC感应到过滤器范围中的Card类型时，会触发Intent,并执行一个Activity。
3）app流程
Main.java相应的代码
public class MainActivity extends AppCompatActivity implements ActiveCallBack {private OTGReadCardAPI ReadCardAPI = null;private NfcAdapter nfcAdapter = null;private String mName = null;private String mIDNO = null;private int mSex;private PendingIntent pi = null;private IntentFilter tagDetected = null;private String[][] mTechLists;private NfcAdapter mAdapter = null; // 定义NFC适配器private Intent inintent = null;TextView tv_name, tv_sex, tv_idno;Button bt_act;private boolean bTestServer = false;private boolean bNFC = false;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.act_main);tv_name = findViewById(R.id.name);tv_sex = findViewById(R.id.sex);tv_idno = findViewById(R.id.IDNO);bt_act = findViewById(R.id.bt_action);init();//初始化NFC读卡器// String m_szAppKey = getSharedPreferences("appConfig",MODE_PRIVATE).getString("AppKey", "");// ReadCardAPI = new OTGReadCardAPI(getApplicationContext(), this, bNFC);// bt_act.setOnClickListener(new View.OnClickListener() {// @Override// public void onClick(View view) {nfcRead(getIntent()); //NFC读信息new MyTask().execute(); //启动线程new Thread(new Runnable() {@Overridepublic void run() {nfcRead(getIntent());}});// }//// });PermissionUtil.grantNeedPermission(this); //添加权限}public void nfcRead(Intent intent) {/**5445454225474* NFC读卡过程** */// ReadCardAPI = new OTGReadCardAPI(getApplicationContext(), this, false);// //配置服务器// ArrayList<Serverinfo> twoCardServerlist = new ArrayList<Serverinfo>();// twoCardServerlist.add(new Serverinfo("", 8848)); // TygerZH server测试// ReadCardAPI.setServerInfo(twoCardServerlist, null, bTestServer);// //读卡// nfcAdapter = NfcAdapter.getDefaultAdapter(this);// if (nfcAdapter == null) {// Toast.makeText(this, "暂不支持NFC功能", Toast.LENGTH_LONG).show();// return;// }// if (nfcAdapter != null && !nfcAdapter.isEnabled()) {// Toast.makeText(this, "请在系统设置中先启用NFC功能", Toast.LENGTH_LONG).show();// finish();// return;// }String AppKey = "A2E91A7BF13C75AADB0400B8701FD284"; // 手机号码注册返回的数据AppKeyint code = ReadCardAPI.NfcReadCard(AppKey, null, intent, eCardType.eTwoGeneralCard, "", false);int erro_code = ReadCardAPI.GetErrorCode();if (code == 90) {//解码成功//获取信息mName = ReadCardAPI.GetTwoCardInfo().szTwoIdName;mIDNO = ReadCardAPI.GetTwoCardInfo().szTwoIdNo;mSex = ReadCardAPI.GetTwoCardInfo().nTwoIdSex;tv_name.setText("");tv_sex.setText("");tv_idno.setText("");tv_name.setText(mName);tv_sex.setText(mSex);tv_idno.setText(mIDNO);} else {//解码失败Toast.makeText(this, "解码失败" + code + ":" + erro_code, Toast.LENGTH_LONG).show();}}public void init() {ReadCardAPI = new OTGReadCardAPI(getApplicationContext(), this, bNFC);ArrayList<Serverinfo> twoCardServerlist = new ArrayList<Serverinfo>();twoCardServerlist.add(new Serverinfo("", 8848)); // TygerZH server测试ReadCardAPI.setServerInfo(twoCardServerlist, null, bTestServer);mAdapter = NfcAdapter.getDefaultAdapter(getApplicationContext());if (mAdapter != null) {init_NFC();} else {if (ReadCardAPI != null) {Toast.makeText(this, "本机不支持NFC功能", Toast.LENGTH_SHORT).show();}}}private void init_NFC() {pi = PendingIntent.getActivity(this, 0, new Intent(this, getClass()).addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP), 0);tagDetected = new IntentFilter(NfcAdapter.ACTION_TECH_DISCOVERED);//.ACTION_TAG_DISCOVERED);tagDetected.addCategory(Intent.CATEGORY_DEFAULT);mTechLists = new String[][]{new String[]{NfcB.class.getName()}, new String[]{NfcA.class.getName()}};if (mAdapter != null && !mAdapter.isEnabled()) {Toast.makeText(this, "NFC尚未开启", Toast.LENGTH_SHORT).show();}}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.menu_main, menu);return true;}@Overridepublic boolean onOptionsItemSelected(MenuItem item) {// Handle action bar item clicks here.
