In a recent development work, I need to develop an app that contains the monitoring and control part of the Hikvision camera. After contacting the Hikvision SDK engineer with the resources already on the Internet, I finally realized the required functions. The following is my development process The code and steps of the monitoring part of, share with you, I hope to help, but also thanks to the online resources. My development is to use Android studio, in a local area network environment, several cameras are plugged into the router, and then the mobile phone and the camera are monitored under the same network segment.
Realization effect:
After the effect is displayed, the next step is the development step. During my development process, I spent a considerable amount of time looking for Haikang’s sdk and jar packages. First, I looked for it on Baidu. Many of them were not available. Then got the SDK (source download address will be provided at the end of the article). After the preparatory work is completed, the next step is the realization step.
1. First, we need to import the sdk and jar packages, I won’t go into details here, just put the screenshot of the directory
2. Don't forget to open the permissions, I forgot to open the permissions, which caused a long delay:
<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"/>3. After we import the jar package and sdk, we need to import it in gradle and synchronize. Put the following two pieces of code into the corresponding bulid.gradle
sourceSets.main {
jniLibs.srcDirs = ['libs']
}
compile files('libs/AudioEngineSDK.jar')
compile files('libs/HCNetSDK.jar')
compile files('libs/jna.jar')
compile files('libs/PlayerSDK.jar')4. Next, we write the layout, the following is my layout file code.
<?xml version="1.0" encoding="utf-8"?>

</LinearLayout>
</AbsoluteLayout>5. Here is the most important part to start writing, in MainActivity:
a. All we need to do is to connect to the camera (login), which requires password, account number, IP, and port information. Take mine as an example (admin, admin123, 192.168.137.1, 8001).
m_oLoginBtn.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
m_oIPAddr = "192.168.137.1";
m_oPort = "8001";
try {
if (m_iLogID < 0) {
// login on the device
m_iLogID = loginDevice();
if (m_iLogID < 0) {
Log.e(TAG, "This device logins failed!");
return;
} else {
System.out.println("m_iLogID=" + m_iLogID);
}
// get instance of exception callback and set
ExceptionCallBack oexceptionCbf = getExceptiongCbf();
if (oexceptionCbf == null) {
Log.e(TAG, "ExceptionCallBack object is failed!");
return;
}
if (!HCNetSDK.getInstance().NET_DVR_SetExceptionCallBack(
oexceptionCbf)) {
Log.e(TAG, "NET_DVR_SetExceptionCallBack is failed!");
return;
}
m_oLoginBtn.setText("Logout");
Log.i(TAG,
"Login sucess ****************************1***************************");
} else {
// whether we have logout
if (!HCNetSDK.getInstance().NET_DVR_Logout_V30(m_iLogID)) {
Log.e(TAG, " NET_DVR_Logout is failed!");
return;
}
m_oLoginBtn.setText("西南摄像机");
m_iLogID = -1;
}
} catch (Exception err) {
Log.e(TAG, "error: " + err.toString());
}
}
});b. The next step is to implement our play click event, and paste the code directly:
m_oPreviewBtn.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
try {
if (m_iLogID < 0) {
Log.e(TAG, "please login on device first");
return;
}
if (m_bNeedDecode) {
if (m_iChanNum > 1)// preview more than a channel
{
if (!m_bMultiPlay) {
m_bMultiPlay = true;
m_oPreviewBtn.setText("停止");
} else {
stopMultiPreview();
m_bMultiPlay = false;
m_oPreviewBtn.setText("播放");
}
} else // preivew a channel
{
if (m_iPlayID < 0) {
startSinglePreview();
} else {
stopSinglePreview();
m_oPreviewBtn.setText("播放");
}
}
} else {
}
} catch (Exception err) {
Log.e(TAG, "error: " + err.toString());
}
}
});
c. The last is our control button. Here I will write left turn and right turn on a button, the first time I click to turn left, the second time I click to turn right:
m_oPTZBtn.setOnTouchListener(new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
try {
if (m_iLogID < 0) {
Log.e(TAG, "please login on a device first");
return false;
}
if (event.getAction() == MotionEvent.ACTION_DOWN) {
if (m_bPTZL == false) {
if (!HCNetSDK.getInstance().NET_DVR_PTZControl_Other(
m_iLogID, m_iStartChan, PTZCommand.PAN_LEFT, 0)) {
Log.e(TAG,
"start PAN_LEFT failed with error code: "
+ HCNetSDK.getInstance()
.NET_DVR_GetLastError());
} else {
Log.i(TAG, "start PAN_LEFT succ");
}
} else {
if (!HCNetSDK.getInstance()
.NET_DVR_PTZControl_Other(m_iLogID,
m_iStartChan, PTZCommand.PAN_RIGHT, 0)) {
Log.e(TAG,
"start PAN_RIGHT failed with error code: "
+ HCNetSDK.getInstance()
.NET_DVR_GetLastError());
} else {
Log.i(TAG, "start PAN_RIGHT succ");
}
}
} else if (event.getAction() == MotionEvent.ACTION_UP) {
if (m_bPTZL == false) {
if (!HCNetSDK.getInstance().NET_DVR_PTZControl_Other(
m_iLogID, m_iStartChan, PTZCommand.PAN_LEFT, 1)) {
Log.e(TAG, "stop PAN_LEFT failed with error code: "
+ HCNetSDK.getInstance()
.NET_DVR_GetLastError());
} else {
Log.i(TAG, "stop PAN_LEFT succ");
}
m_bPTZL = true;
m_oPTZBtn.setText("右转");
} else {
if (!HCNetSDK.getInstance()
.NET_DVR_PTZControl_Other(m_iLogID,
m_iStartChan, PTZCommand.PAN_RIGHT, 1)) {
Log.e(TAG,
"stop PAN_RIGHT failed with error code: "
+ HCNetSDK.getInstance()
.NET_DVR_GetLastError());
} else {
Log.i(TAG, "stop PAN_RIGHT succ");
}
m_bPTZL = false;
m_oPTZBtn.setText("左转");
}
}
return true;
} catch (Exception err) {
Log.e(TAG, "error: " + err.toString());
return false;
}
}
});
