I am getting the above error when running towards an Android (4.4.4) device. I use the java-client (1.7.0) on MAC and do something like this in my code:
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("app", cfg.getAppPath());
capabilities.setCapability("platformName", "Android");
capabilities.setCapability("deviceName", "Android");
capabilities.setCapability("appPackage", "com.something.sample");
capabilities.setCapability("appActivity", "SomeActivity");
AppiumDriver appium = new AppiumDriver(cfg.getAppiumUrl(), capabilities);
// do something....
// then
appium.closeApp();
appium.quit();
When calling the quit() method an exception is thrown. And the below is showing in the Appium log window. What can be the cause of this?
