80 | break; 81 | case SUPPORT_WITHOUT_DATA: 82 | showToast("请在系统录入指纹后再验证"); 83 | break; 84 | case SUPPORT: 85 | FingerManager.build().setApplication(getApplication()) 86 | .setTitle("指纹验证") 87 | .setDes("请按下指纹") 88 | .setNegativeText("取消") 89 | // .setFingerDialogApi23(new MyFingerDialog())//如果你需要自定义android P 以下系统弹窗就设置,注意需要继承BaseFingerDialog，不设置会使用默认弹窗 90 | .setFingerCallback(new SimpleFingerCallback() { 91 | @Override 92 | public void onSucceed() { 93 | showToast("验证成功"); 94 | } 95 | 96 | @Override 97 | public void onFailed() { 98 | showToast("指纹无法识别"); 99 | } 100 | 101 | @Override 102 | public void onChange() { 103 | showToast("指纹数据发生了变化"); 104 | } 105 | }) 106 | .create() 107 | .startListener(MainActivity.this); 108 | break; 109 | default: 110 | } 111 | } 112 | } 113 | }); 114 | ``` 115 | 116 | ### 支持功能 117 | 118 | 1. 检查设备是否支持指纹：分为三种支持，分别是（1）设备没有指纹识别器 （2）设备有指纹识别器但是没有指纹数据（3）设备有识别器并且有指纹数据，可以进行指纹验证 119 | 1. 　监听相应手机指纹库数据发生变化的情况 120 | 2. 　指纹数据发生变化后可以调用updateFingerData()方法更新同步变化 121 | 1. 　能够对取消指纹识别和指纹识别失败分别进行处理 122 | 1. 　需要适配android版本，在android版本大于6.0 小于9.0 的情况下要自己实现指纹识别弹窗。在android P上要使用最新Api调用指纹识别统一弹窗 123 | 124 | ### 如何监听指纹数据变化 125 | 126 | 1. 创建SecretKey对当前指纹数据加密，如果在创建SecretKey后添加新指纹,则会在Cipher初始化时引发KeyPermanentlyInvalidatedException.通过这个异常我们可以知道指纹数据是否发生变化 127 | 128 | ``` 129 | /** 130 | * @des 初始化Cipher ,根据KeyPermanentlyInvalidatedExceptiony异常判断指纹库是否发生了变化 131 | * 132 | */ 133 | public boolean initCipher(Cipher cipher) { 134 | try { 135 | keyStore.load(null); 136 | SecretKey key = (SecretKey) keyStore.getKey(KEYSTORE_ALIAS, null); 137 | if (cipher == null) { 138 | cipher = createCipher(); 139 | } 140 | cipher.init(Cipher.ENCRYPT_MODE, key); 141 | return false; 142 | } catch (KeyPermanentlyInvalidatedException e) { 143 | //指纹库是否发生了变化,这里会抛KeyPermanentlyInvalidatedException 144 | return true; 145 | } catch (KeyStoreException | CertificateException | UnrecoverableKeyException | IOException 146 | | NoSuchAlgorithmException | InvalidKeyException e) { 147 | throw new RuntimeException("Failed to init Cipher", e); 148 | 149 | } 150 | } 151 | ``` 152 | 153 | 2. 唯一例外的是三星手机不会抛出KeyPermanentlyInvalidatedException这个异常，经过反复测试，发现三星手机可以根据识别成功后的回调方法中检测cipher.doFinal(SECRET_MESSAGE.getBytes())这里的异常判断指纹数据是否发生变化 154 | 155 | ``` 156 | @Override 157 | public void onAuthenticationSucceeded(FingerprintManager.AuthenticationResult result) { 158 | super.onAuthenticationSucceeded(result); 159 | Cipher cipher = result.getCryptoObject().getCipher(); 160 | if (cipher != null) { 161 | try { 162 | /* 163 | * 用于检测三星手机指纹库变化， 164 | * 三星手机指纹库发生变化后前面的initCipher检测不到KeyPermanentlyInvalidatedException 165 | * 但是cipher.doFinal(SECRET_MESSAGE.getBytes())会抛出异常 166 | * 因此以此监听三星手机的指纹库变化 167 | */ 168 | 169 | cipher.doFinal(SECRET_MESSAGE.getBytes()); 170 | 171 | cancel.cancel(); 172 | mFingerDialog.onSucceed(); 173 | mFingerCallback.onSucceed(); 174 | } catch (Exception e) { 175 | e.printStackTrace(); 176 | mFingerCallback.onChange(); 177 | } 178 | } 179 | ``` 180 | 181 | 182 | ### 自定义android 9.0以下弹窗 183 | 184 | 如果你想自定义android M 的指纹识别弹窗,很简单,你只需要: 185 | 186 | 1. 继承BaseFingerDialog类 187 | 1. 在onCreateView中初始化你自己的布局 188 | 1. 实现onSucceed()、onFailed（）、onHelp（）、onError（）四个回调就好了，这四个回调建议只做UI相关操作，逻辑操作已经在外部提供了回调接口。 189 | 1. onSucceed ：指纹识别成功，可以直接关闭弹窗 190 | 1. onFailed ： 当识别的手指没有注册时回调,但是可以继续验证 191 | 1. onHelp ： 指纹识别不对,会提示,手指不要大范围移动等信息,可以继续验证 192 | 1. onError ：指纹识别彻底失败,不能继续验证 193 | 1. 一个指纹识别事件序列是这样的： 开始识别 ---> (onHelp / onFaild) (0个或多个) ---> onSucceed / onError 194 | 195 | 调起指纹识别得时候,将自定义的弹窗设置进去,代码如下,如果你不设置自定义弹窗会使用默认的android M 弹窗 196 | ``` 197 | FingerManager.build().setApplication(getApplication()) 198 | .setTitle("指纹验证") 199 | .setDes("请按下指纹") 200 | .setNegativeText("取消") 201 | .setFingerDialogApi23(new MyFingerDialog()) 202 | .setFingerCheckCallback() 203 | ``` 204 | ### 意见反馈 205 | 如发现有错误地方欢迎指教，QQ:932599583 206 | 207 | ### 参考链接 208 | 209 | https://github.com/googlearchive/android-FingerprintDialog 210 | https://android.ctolib.com/mengcuiguang-FingerDemo.html 211 | -------------------------------------------------------------------------------- /app/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | -------------------------------------------------------------------------------- /app/build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.application' 2 | 3 | android { 4 | compileSdkVersion 29 5 | buildToolsVersion "29.0.3" 6 | 7 | defaultConfig { 8 | applicationId "com.xiao.biometricmanager" 9 | minSdkVersion 21 10 | targetSdkVersion 29 11 | versionCode 1 12 | versionName "1.0" 13 | 14 | testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" 15 | } 16 | 17 | buildTypes { 18 | release { 19 | minifyEnabled false 20 | proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' 21 | } 22 | } 23 | 24 | } 25 | 26 | dependencies { 27 | implementation fileTree(dir: 'libs', include: ['*.jar']) 28 | 29 | implementation 'androidx.appcompat:appcompat:1.1.0' 30 | implementation 'androidx.constraintlayout:constraintlayout:1.1.3' 31 | testImplementation 'junit:junit:4.12' 32 | androidTestImplementation 'androidx.test.ext:junit:1.1.1' 33 | androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0' 34 | 35 | implementation project(':biometricmanagerlib') 36 | } 37 | -------------------------------------------------------------------------------- /app/proguard-rules.pro: -------------------------------------------------------------------------------- 1 | # Add project specific ProGuard rules here. 2 | # You can control the set of applied configuration files using the 3 | # proguardFiles setting in build.gradle. 4 | # 5 | # For more details, see 6 | # http://developer.android.com/guide/developing/tools/proguard.html 7 | 8 | # If your project uses WebView with JS, uncomment the following 9 | # and specify the fully qualified class name to the JavaScript interface 10 | # class: 11 | #-keepclassmembers class fqcn.of.javascript.interface.for.webview { 12 | # public *;
