（org.openqa.selenium.WebDriverException: Unable to launch the app: Error: Trying to start logcat capture but it's already started! ）错误解决办法

新增：

capabilities.setCapability("autoLaunch",false);

将setup中的：

driver = new AndroidDriver(new URL("http://127.0.0.1:" + port + "/wd/hub"), capabilities);

driver.launchApp();

第二句：

driver.launchApp()

注释掉
