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

01:5555","fullReset":"false","appActivity":"com.sf.module.edms.hibox.ui.entry.EntryActivity","newCommandTimeout":24000,"platformVersion":"4.4","browserName":"","udid":"192.168.56.101:5555","platformName":"Android","device":"selendroid"}}

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
