Pre-requisites:
I assume you have installed the followings in your machine already.
Appium is downloaded (latest from here) and setup properly as mentioned here.
Java Development Kit(JDK) is downloaded(refer here) and installed in your machine.
How to Start or Stop appium server programmatically?
Please refer the below class for detailed usage, Hope it is self explanatory.
Method-1:
With the above approach of starting appium server, you can get total android log in the provided log file i.e. "androidlog.txt" file inside "log" directory of your project root directory
Method-2
Here is an another way of starting and killing appium server programmatically using command line executions with java's ProcessBuilder class. Refer below class for more details.
Define the below properties and change as per your appium installation.

public class AppiumServer {
String appiumInstallationDir = "C:/Program Files (x86)";// e.g. in Windows
//String appiumInstallationDir = "/Applications";// e.g. for Mac
AppiumDriverLocalService service = null;
public AppiumServer() {
File classPathRoot = new File(System.getProperty("user.dir"));
String osName = System.getProperty("os.name");

} else {
// you can add for other OS, just to track added a fail message
Assert.fail("Starting appium is not supporting the current OS.");

* Starts appium server
*/
public void startAppiumServer() {
service.start();
}
/**
* Stops appium server

public void stopAppiumServer() {

}
}
Usage of this class:AppiumServer service = new AppiumServer(); // Starts appium server service.startAppiumServer(); // ... your tests are here. // Stops appium server service.stopAppiumServer();Note: You can call start appium server in the @BeforeSuite configuration method and stop appium server at @AfterSuite configuration methods.
With the above approach of starting appium server, you can get total android log in the provided log file i.e. "androidlog.txt" file inside "log" directory of your project root directory
Method-2
Here is an another way of starting and killing appium server programmatically using command line executions with java's ProcessBuilder class. Refer below class for more details.
Define the below properties and change as per your appium installation.
String appiumInstallationDir = "C:/Program Files (x86)"; String appiumNode = appiumInstallationDir + File.separator + "Appium" + File.separator + "node.exe"; String appiumNodeModule = appiumInstallationDir + File.separator + "Appium" + File.separator + "node_modules" + File.separator + "appium" + File.separator + "bin" + File.separator + "Appium.js"; String appiumServicePort = "4723";Execute the start and stop commands like we do from command line but here with using java's ProcessBuilder class.
/**
* Starts appium server
*/
public void startAppiumServer() {
executeCommand("\"" + appiumNode + "\" \"" + appiumNodeModule
+ "\" " + "--no-reset --local-timezone");
}
/**
* Stops appium server
*/
public void stopAppiumServer() {
executeCommand("cmd /c echo off & FOR /F \"usebackq tokens=5\" %a in"
+ " (`netstat -nao ^| findstr /R /C:\""
+ appiumServicePort + "\"`) do (FOR /F \"usebackq\" %b in"
+ " (`TASKLIST /FI \"PID eq %a\" ^| findstr /I node.exe`) do taskkill /F /PID %a)");
}
You may need the below class for executing a command line command. This you can do using Runtime.getRuntime().exec(command) also, but I would suggest to use ProcssBuilder as this is recommended.
/**
* Executes any command for Windows using ProcessBuilder of Java You can
* change the first input parameter of ProcessBuilder constructor if your OS
* is not windows operating system
*
* @param aCommand
*/
public void executeCommand(String aCommand) {
File currDir = new File(System.getProperty("user.dir"));
String line;
try {
ProcessBuilder probuilder = new ProcessBuilder("CMD", "/C", aCommand);
probuilder.directory(currDir);
Process process = probuilder.start();
BufferedReader inputStream
= new BufferedReader(new InputStreamReader(process.getInputStream()));
BufferedReader errorStream
= new BufferedReader(new InputStreamReader(process.getErrorStream()));
// reading output of the command
int inputLine = 0;
while ((line = inputStream.readLine()) != null) {
if (inputLine == 0) {
System.out.printf("Output of the running command is: \n");
}
System.out.println(line);
inputLine++;
}
// reading errors from the command
int errLine = 0;
while ((line = errorStream.readLine()) != null) {
if (errLine == 0) {
System.out.println("Error of the command is: \n");
}
System.out.println(line);
errLine++;
}
} catch (IOException e) {
System.err.println("Exception occured: \n");
System.err.println(e.getMessage());
}
}
With the above method, the server log will be printed in the console as I kept standard output and error statements. You can change to trace these log in a log file if you need it.
Hope it is useful !!
