Encountered internal error running command: {"jsonwp":{"value":"java.
lang.NullPointerException\n\tat android.support.test.uiautomator.UiObject2.setTe

兄弟这个问题解决了没?

我也遇上同样的问题了, java-client 5.0.4 + appium desktop 1.2.4 , 也是输入不了密码

        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability("deviceName", "Andorid Emulator");
        capabilities.setCapability("automationName", "uiautomator2");
        capabilities.setCapability("platformName", "Android");
        capabilities.setCapability("platformVersion", "4.4.2");
        capabilities.setCapability("appPackage", "com.test.doctor");
        capabilities.setCapability("appActivity", ".user.UserLoginActivity");
        capabilities.setCapability("newCommandTimeout", 0);
//        capabilities.setCapability("unicodeKeyboard", true);
//        capabilities.setCapability("resetKeyboard", true);

        URL url = new URL("http://127.0.0.1:4723/wd/hub");
        driver = new AndroidDriver(url, capabilities);
        driver.manage().timeouts().implicitlyWait(sleepInterval, TimeUnit.SECONDS);

Appium-desktop 异常为:

另外，安卓版本是否低于 5.0，2 对低版本支持不好
