Hikvision SDK develops JAVADEMO

I recently developed a Hikvision SDK access control and card reader link project, and the following problems appeared in the demo.

错误：java.lang.UnsatisfiedLinkError: Unable to load library ‘HCUsbSDK’: ÕҲ»µ½ָ¶¨

This kind of error means that the HCUsbSDK.dll file cannot be found (the same is true for HCNetSDK.dll). There are two ways to deal with it:

1. Change the relative path to an absolute path.

change to

HCUsbSDK INSTANCE = (HCUsbSDK) Native.loadLibrary("D:\HCUsbSDK",
            HCUsbSDK.class);//我把HCUsbSDK.dll放到了D盘根目录下

2. When the first method is useless, use this method

Change HCUsbSDK.java or HCNetSDK.java to

HCUsbSDK INSTANCE = (HCUsbSDK) Native.loadLibrary("HCUsbSDK",
            HCUsbSDK.class);

Then

copy the HCNetSDKCom folder and all dlls in the library file of the SDK development demo to the project root directory. Run and you're good to go.
