Appium does not initialize driver when launched programatically

Question

I am initializing Appium through command line using Java and Selenium for running test on Android chrome browser. However, the process runs for infinite time and the code from "DesiredCapabilities" line doesn't get executed.. Code :

Process proc;
String path_to_appium = System.getenv("APPIUM_HOME") + File.separator + "node_modules" + File.separator + "appium" + File.separator + "bin" + File.separator + "appium.js";
String path_to_node = System.getenv("APPIUM_HOME") + File.separator + "node.exe";
proc = Runtime.getRuntime().exec("\"" + path_to_node + "\"" + " " + "\"" + path_to_appium + "\"" + " " + "--address 127.0.0.1 --browser-name Chrome --platform-name Android --platform-version 17 --automation-name Appium --chromedriver-port 9516 --bootstrap-port 4724 --no-reset --local-timezone --log appium_log.log");

System.out.println("Android Chrome driver would be used");

DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("platformName","Android");
capabilities.setCapability("deviceName", "HTC One X");
capabilities.setCapability("platformVersion", "4.2.2");
capabilities.setCapability("device", "android");
capabilities.setCapability("browserName", MobileBrowserType.CHROME);

Thread.sleep(2000);
driver = new RemoteWebDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
driver.get("test.com");

I don't get any output in console.

Nothing happens. The process doesn't go on next line (i.e. setting DesiredCapabilities). The chrome doesn't get launched on the device.

Note : When i execute the command from command line, and then start test from DesiredCapabilities line, the test runs fine and chrome is initialized successfully.

What is wrong with the code?

Answer 1

The problem was there in the latest appium version i.e. 1_4_16_1.

When the appium server was launched programatically, it was creating a deadlock because of which the driver was not being initialized.

The issue got solved after using ServerArguments of Appium and replacing the line

proc = Runtime.getRuntime().exec("\"" + path_to_node + "\"" + " " + "\"" + path_to_appium + "\"" + " " + "--address 127.0.0.1 --browser-name Chrome --platform-name Android --platform-version 17 --automation-name Appium --chromedriver-port 9516 --bootstrap-port 4724 --no-reset --local-timezone --log appium_log.log");

with below code :

            ServerArguments serverArguments = new ServerArguments();
            serverArguments.setArgument("--address","127.0.0.1");
            serverArguments.setArgument("--chromedriver-port", 9516);
            serverArguments.setArgument("--bootstrap-port", 4724);
            serverArguments.setArgument("--browser-name", "Chrome");
            serverArguments.setArgument("--no-reset", true);
            serverArguments.setArgument("--local-timezone", true);
            AppiumServer appiumServer = new AppiumServer(appium_folder, serverArguments);
            appiumServer.startServer();
driver = new RemoteWebDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
driver.get("test.com");
