Android 集成海康威视监控 SDK，实现监控录像的查看
配置
切换Android studio 到project目录下，分别将jar包与armeabi包复制进去lib文件夹下：
设置app bulid.gradle文件 主要是添加CPU限制 只支持32位 以及添加so包的路径、添加jar包依赖：
添加权限
<uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/><uses-permission android:name="android.permission.CAPTURE_AUDIO_OUTPUT"/><uses-permission android:name="android.permission.RECORD_AUDIO"/>
SDK使用
在调用摄像头的Activity的oncreate（）中初始化SDK
private boolean initeSdk() {// init net sdkif (!HCNetSDK.getInstance().NET_DVR_Init()) {Log.e(TAG, "HCNetSDK init is failed!");return false;}HCNetSDK.getInstance().NET_DVR_SetLogToFile(3, "/mnt/sdcard/sdklog/",true);//log保存的路径return true;}
登陆
private int loginNormalDevice() {// get instancem_oNetDvrDeviceInfoV30 = new NET_DVR_DEVICEINFO_V30();if (null == m_oNetDvrDeviceInfoV30) {Log.e(TAG, "HKNetDvrDeviceInfoV30 new is failed!");return -1;}// call NET_DVR_Login_v30 to login on, port 8000 as defaultint iLogID = HCNetSDK.getInstance().NET_DVR_Login_V30(ADDRESS, PORT,USER, PSD, m_oNetDvrDeviceInfoV30);if (iLogID < 0) {Log.e(TAG, "NET_DVR_Login is failed!Err:"+ HCNetSDK.getInstance().NET_DVR_GetLastError());return -1;}if (m_oNetDvrDeviceInfoV30.byChanNum > 0) {m_iStartChan = m_oNetDvrDeviceInfoV30.byStartChan;m_iChanNum = m_oNetDvrDeviceInfoV30.byChanNum;} else if (m_oNetDvrDeviceInfoV30.byIPChanNum > 0) {m_iStartChan = m_oNetDvrDeviceInfoV30.byStartDChan;m_iChanNum = m_oNetDvrDeviceInfoV30.byIPChanNum+ m_oNetDvrDeviceInfoV30.byHighDChanNum * 256;}Log.i(TAG, "NET_DVR_Login is Successful!");return iLogID;}
相机预览
//预览final NET_DVR_PREVIEWINFO ClientInfo = new NET_DVR_PREVIEWINFO();ClientInfo.lChannel = 0;ClientInfo.dwStreamType = 0; // substreamClientInfo.bBlocked = 1;//设置默认点thread = new Thread(new Runnable() {@Overridepublic void run() {while (!Thread.currentThread().isInterrupted()) {SystemClock.sleep(1000);runOnUiThread(new Runnable() {@Overridepublic void run() {if (isShow)startSinglePreview();//预览}});}}});thread.start();
预览摄像头需要开启线程，监听预览成功后停止线程，不然界面会显示黑色。
startSinglePreview()代码：
private void startSinglePreview() {if (m_iPlaybackID >= 0) {Log.i(TAG, "Please stop palyback first");return;}RealPlayCallBack fRealDataCallBack = getRealPlayerCbf();if (fRealDataCallBack == null) {Log.e(TAG, "fRealDataCallBack object is failed!");return;}Log.i(TAG, "m_iStartChan:" + m_iStartChan);NET_DVR_PREVIEWINFO previewInfo = new NET_DVR_PREVIEWINFO();previewInfo.lChannel = m_iStartChan;previewInfo.dwStreamType = 0; // substreampreviewInfo.bBlocked = 1;m_iPlayID = HCNetSDK.getInstance().NET_DVR_RealPlay_V40(m_iLogID,previewInfo, fRealDataCallBack);if (m_iPlayID < 0) {Log.e(TAG, "NET_DVR_RealPlay is failed!Err:"+ HCNetSDK.getInstance().NET_DVR_GetLastError());return;}isShow = false;if (NotNull.isNotNull(thread)) {thread.interrupt();}h1 = new CameraManager();h1.setLoginId(m_iLogID);Intent intent = getIntent();if (NotNull.isNotNull(intent) && intent.getIntExtra("INDEX", -1) != -1) {int point = app.preferences.getInt("POINT", 0);boolean b = HCNetSDK.getInstance().NET_DVR_PTZPreset(m_iPlayID, PTZCommand.GOTO_PRESET,point);}}

以上讲的是旧版本，转自wangguan_9527 博客地址海康威视 Android studio 集成使用_wangguan_9527的博客-CSDN博客
新版本：
SDK(代码比较繁琐，不易看懂)地址：海康开放平台（设备网络SDK_Android V6.1.9.4_build0412）
对sdk进行了缩减，源码地址：HKSDK_demo: Android版海康威视摄像头视频最新版sdk接入。
