Android 手把手教你实现百度身份证识别

踩

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： 在这里插入图片描述
把解压的文件导入您Android studio 的 project 中具体操作如下：

在这里插入图片描述
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：
1

 /* 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

在这里插入图片描述

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

七、上代码

1.新建一个类
1

public class FileUtilll {
    public static File getSaveFile(Context context) {
        File file = new File(context.getFilesDir(), "pic.jpg");
        return file;
    }
}
