Android 集成第三方SDK

6月 一切有为法 有如梦幻泡影 如梦亦如幻 如露亦如电 当作如是观 

一.客户需求

1.1.在系统里面集成 第三方SDK 即将aar资源集成到系统层 让应用调用

1.2.客户的算法代码也集成到源码当中去

二.先做到 能调用jar包吧

2.1.内置

a./frameworks/opt/demosdk/ 加入资源 并加入编译规则

Android.mk

?

1 2 3 4 5 6 7 8

LOCAL_PATH := $(my-dir)   include $(CLEAR_VARS)   LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := MVIDCodeReaderSDKYP:MVIDCodeReaderSDKYP.jar \                         MVIDCodeReaderWrapperYP:MVIDCodeReaderWrapperYP.jar   include $(BUILD_MULTI_PREBUILT)

b.这里是调用jar 的方法

 需要实现的接口

d. 加入编译

e.上层应用 调用 framework层能用到的jar包

   同写一样的接口  这里是为了 能够拿到回调方法的数据 

      iyunpanCodeReaderManager.setOnPreviewCallBack

　　　　mlistener.getImageInfo(pImageInfo, l_nImageLen, mYpImageType, mWidth, mHeight, mFrameNum);

?

  都是通过反射来 获取上层的方法
