baidu ocr 加载授权文件

最近因为项目需要，进行了集成百度身份证识别的验证damo；

很多地方都是按照官方的来的，能力强的小伙伴可以直接看官方damo；


一，创建项目，并下载SDK


1>去百度大脑处注册账号并创建项目，地址：https://ai.baidu.com/

    1.1点击控制台，进入管理中心



1.2 进入管理中心后，点击左侧产品服务，选择文字识别



1.3 进入文字识别概览，选择创建应用，点击立即创建



1.4 按照要求填好资料，出于安全考虑还是绑定包名



1.4提示创建成功后点击 下载SDK



1.5下载 文字识别里的Android SDK



二，集成SDK

2.1 把包内的libs文件下的所有文件放入Android Stuio项目中的libs里

当然ocr-sdk.jar包记得 右键add as library；


由于个人习惯的原因，官方要求的是放到jnilibs 我没有按照官方要求的做，所以还要在build.gradle里添加以下代码

sourceSets {
        main {
            jniLibs.srcDir(['libs'])
        }
    }


2.2 把orc_ui文件以模块方式导入到项目里



2.3 引入后还有最后一步，把授权文件aip.license放入到assets目录中,这步很重要，不做会导致授权失败，无法识别

授权文件 aip.license在这个位置下载




三，代码实现


首先是布局


  1. <?xml version="1.0" encoding="utf-8"?>

还有个FileUtil工具类

  4. package com.example.administrator.baiduidcard;
  5.  
  6. import android.content.Context;
  7.  
  8. import java.io.File;
  9.  
  10. public class FileUtil {
  11.     public static File getSaveFile(Context context) {
  12.         File file = new File(context.getFilesDir(), "pic.jpg");
  13.         return file;
  14.     }
  15. }
