Launching and stopping appium server programmtically

maxski · Apr '15

Hi Hasan,

It's unbelievable, I've faced the same issue with ProcessBuilder like you just only now:-) I don;t know why it works previously and I why it doesn't work now.
However, I started using apache commons exec for parallel running and it works like a charm:-)

So start is:
private Executor appiumProcess;
CommandLine cmdLine = new CommandLine(command);
DefaultExecuteResultHandler resultHandler = new DefaultExecuteResultHandler();
ExecuteWatchdog watchdog = new ExecuteWatchdog(ExecuteWatchdog.INFINITE_TIMEOUT);
PumpStreamHandler streamHandler = new PumpStreamHandler(new FileOutputStream("Device" + deviceIndex + "Logs.txt"));
appiumProcess = new DefaultExecutor();
appiumProcess.setExitValue(0);
appiumProcess.setWatchdog(watchdog);
appiumProcess.setStreamHandler(streamHandler);
appiumProcess.execute(command, resultHandler);

Stop is simple:
appiumProcess.getWatchdog().destroyProcess();

Cmd creation smth like that:
CommandLine cmd = new CommandLine("node");
cmd.addArgument(PropertyLoader.get("appium.path"));
cmd.addArgument("-a");
cmd.addArgument(PropertyLoader.get("appium.host"));
cmd.addArgument("-p");
cmd.addArgument(String.valueOf(Integer.parseInt(PropertyLoader.get("appium.port")) + deviceIndex));
cmd.addArgument("-bp");
cmd.addArgument(String.valueOf(Integer.parseInt(PropertyLoader.get("appium.bootstrapPort")) + deviceIndex));
cmd.addArgument("-U");
cmd.addArgument(device.getUDID());

Hello Husain,

In My case I am Getting Error as:

Please provide your code snippet that led to this error??

Yah ...Here it is:

Try putting your Appium files in C directory and give it another try.

And Console Output (Error) for This code is:

Starting Server...
Server Started....
Stopping Server
Server Stopped
ERROR: The process "node.exe" not found.

Hassan_Radi · Apr '15

This line should not be added as it is already covered by previous points. Please remove it and see what happens.

The server didn't start and that is why it is failing with the mentioned error. Can you try it with Java Process and see if it produces the same error??

appiumshaik · Apr '15

even though if we put false for no-reset/full-reset..the logs are showing as true. Has anyone faced the same issue?

      command.addArgument("--full-reset", false);

or
command.addArgument("--no-reset", false);

The appium is launched as
[36minfo[39m: [debug] Non-default server args: {"address":"127.0.0.1","noReset":true,"log":"D:/appiumLogs.txt"}

AjitJ · Apr '15

Mayuresh_Shirodkar · May '15

Thanks @Hassan_Radi..For providing this code.Helped alot.
Great Job

Hassan_Radi · May '15

For anyone who is still having problems getting the server to start programmatically, you can refer to this post about a new library called Appium Support216.

Hope it helps.

I'm getting an error like

C:/Program' is not recognized as an internal or external command,
operable program or batch file.

CODE:

public void startAppiumServer() throws IOException, InterruptedException {   

        CommandLine command = new CommandLine("cmd");
        command.addArgument("/c");
        command.addArgument("C:/Program Files (x86)/Appium/node.exe");  
        command.addArgument("C:/Program Files (x86)/Appium/node_modules/appium/lib/appium.js");  
        command.addArgument("--address", false);  
        command.addArgument("127.0.0.1");  
        command.addArgument("--port", false);  
        command.addArgument("4723");  
        command.addArgument("--full-reset", false);  

        DefaultExecuteResultHandler resultHandler = new DefaultExecuteResultHandler();  
        DefaultExecutor executor = new DefaultExecutor();  
        executor.setExitValue(1);  
        executor.execute(command, resultHandler);
    }

Found the solution for this problem

Actually the space between the folder names is the root cause. The spaces should not occur in between the words.

C:/Program Files (x86)/Appium/node.exe

The Spaces should not occur

wreed · Jun '15

In Java I think you need to escape the spaces in double quotes. You could use single quotes to get around this.

ashokkumarg · Jun '15

@Hassan_Radi Could you explain the meaning of it

command.addArgument("--address", true);
command.addArgument("127.0.0.1");

command.addArgument("--port", false);
command.addArgument("4722");

command.addArgument("--full-reset", false);

I am getting the same issue when running the appium launch via java code in eclipse

Thank you in Advance.
