Appium 一个测试套件多次启动android应用

 AppiumDriver<WebElement> driver;

         File classpathRoot = new File(System.getProperty("user.dir"));

            File appDir = new File(classpathRoot, "app");

            // 微信程序

            File app = new File(appDir, "xxxx.sp1_test2.apk");

            //设置自动化相关参数

            DesiredCapabilities capabilities = new DesiredCapabilities();

            capabilities.setCapability(CapabilityType.BROWSER_NAME, "");

            capabilities.setCapability("deviceName", "192.168.56.101:5555");

            capabilities.setCapability("udid", "192.168.56.101:5555");

            //设置每次运行不重新启动被测试app

            capabilities.setCapability("noReset","true");

            capabilities.setCapability("fullReset","false");

            //设置安卓系统版本

            capabilities.setCapability("platformVersion", "4.4");

            capabilities.setCapability("platformName", "Android");

            // session 延迟时间

            capabilities.setCapability("newCommandTimeout",24000);

            capabilities.setCapability("device", "selendroid");

            capabilities.setCapability("app", app.getAbsolutePath());

            String abc = app.getAbsolutePath();

            //设置app的主包名和主类名

            capabilities.setCapability("appPackage", "com.sf.module.edms");

            capabilities.setCapability("appActivity", "com.sf.module.edms.hibox.ui.entry.EntryActivity");

            //启动

             try {

                driver = new AndroidDriver<WebElement>(new URL("http://127.0.0.1:4723/wd/hub"),capabilities);

            } catch (MalformedURLException e) {

                // TODO Auto-generated catch block

                e.printStackTrace();

            } 

多次运行，就会出错

增加语句

driver.closeApp();
driver.quit();

并且在appium里面设置

tool ->general settings- > select overriding existing sessions

在一个测试任务中，多次启动app driver 都能正常启动
