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

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

package android.os.ypinterfaces;

import java.util.List;

import static com.yunpan.codereader.MVIDCodeReaderDefine.MVID_IMAGE_INFO;

public interface YpCodeReaderManagerInterfaces {
    void getCodeInfo(List<String> listCode);

    /* public byte[] pImageBuf;
     public int nImageLen = 0;
     public MVIDCodeReaderDefine.MVID_IMAGE_TYPE enImageType;
     public short nWidth = 0;
     public short nHeight = 0;
     public int nFrameNum = 0;*/
    void getImageInfo(byte[] pImageBuf, int nImageLen,int enImageType ,int nWidth, int nHeight,int nFrameNum);
}

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);

package android.os.ypinterfaces;

import java.util.List;

public interface YpCodeReaderManagerInterfaces {
    void getCodeInfo(List<String> listCode);
    void getImageInfo(byte[] pImageBuf, int nImageLen, int enImageType, int nWidth, int nHeight,int nFrameNum);
}

都是通过反射来获取上层的方法

activity_main.xml

    android:layout_width="match_parent"
    android:layout_height="match_parent"
