Android 手把手教你实现百度身份证识别
一、集成身份证识别第一步首先要在有自己的AppID 和签名的前提下进行去官网 下载文字识别的SDK ：
地址：https://ai.baidu.com/sdk#ocr
二、 权限 (如果清单有权限就不用添加小心demo崩溃)
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
三、 将下载的SDK解压打开 如图：
把解压的文件导入您Android studio 的 project 中具体操作如下：
注意往下看
点击ok后 直接finish 这样就把文字识别的SDK导入进来了
**四、把解压的文件再打开 → 点击 libs 文件夹 把文件 Ctrl+A 直接 CV 大法粘贴到自己studio 的当前model 也要在assets 文件夹中 导入 aip.license 文件 **
五、导入依赖
1. 在android { } 中添加依赖：
/* Java版本 使用1.8 */
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
//jniLibs
sourceSets {
main {
jniLibs.srcDirs = ['libs']
}
}
2.在dependencies { } 中加入百度识别的依赖
//识别身份证
//EventBus 依赖
implementation 'org.greenrobot:eventbus:3.1.1'
//百度识别依赖
compile 'com.android.support:appcompat-v7:25.1.1'
compile files('libs/ocr-sdk.jar')
compile project(path: ':ocr_ui')
第二行报红正常 可以当没看见 不用在意
3.在当前model 的 proguard-rules.pro 加两行效果如图
代码在这呢：
-keep class com.baidu.ocr.sdk.**{*;}
-dontwarn com.baidu.ocr.**
六 创建一下自己的布局
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

七、上代码
1.新建一个类
public class FileUtilll {
public static File getSaveFile(Context context) {
File file = new File(context.getFilesDir(), "pic.jpg");
return file;
}
}
2.最后一步
public class ShiName_Activity extends AppCompatActivity {
@BindView(R.id.xin_fan)
ImageView xinFan;
@BindView(R.id.qq)
LinearLayout qq;
@BindView(R.id.ww)
TextView ww;
@BindView(R.id.ee)
ImageView ee;
@BindView(R.id.shi_xiang)
ImageView shiXiang;
@BindView(R.id.shi_xiang2)
TextView shiXiang2;
@BindView(R.id.rr)
ImageView rr;
@BindView(R.id.tt)
ImageView tt;
@BindView(R.id.tt2)
TextView tt2;
@BindView(R.id.xiayibu)
TextView xiayibu;
