UiAutomator Appium 可以捕获 toast 消息了,但是无法输入密码

我们公司的app是需要登录的, 之前capabilities.setCapability("automationName", "Appium");的时候一切都好.

为了捕获toast消息, 使用了capabilities.setCapability(MobileCapabilityType.AUTOMATION_NAME, AutomationName.ANDROID_UIAUTOMATOR2);(参考carl的文章https://testerhome.com/topics/8335), 现在的问题是可以捕获toast消息,但是却无法登录. 每次一输入密码就报空指针异常. (输入密码行就是被注释的那行)

环境:
APPIUM Version: 1.7.1
JAVA Client: 5.0.4
JAVA: 1.8
UiAutomator2 Drvier(版本未知, 不知道咋看)

代码如下:

import io.appium.java_client.android.AndroidDriver;

public class Test3 {

    private AndroidDriver driver = null;
    private int sleepInterval = 15;
    private Log log = LogFactory.getLog(this.getClass().getName());

    @Before
    public void setUp() throws MalformedURLException {
        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability("deviceName", "Andorid Emulator");
        capabilities.setCapability(MobileCapabilityType.AUTOMATION_NAME, AutomationName.ANDROID_UIAUTOMATOR2);
        capabilities.setCapability("platformName", "Android");
        capabilities.setCapability("platformVersion", "4.4.2");
        capabilities.setCapability("appPackage", "com.testgroup.testdoctor");
        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);
    }

    @After
    public void tearDown() {
        driver.quit();
    }

    @Test
    public void logonTest() throws InterruptedException, MalformedURLException {

        // 登录页面
        driver.findElement(By.id("com.testgroup.testdoctor:id/username")).sendKeys("13439155766");
        driver.findElement(By.id("com.testgroup.testdoctor:id/pwd")).click();
//        driver.findElement(By.id("com.testgroup.testdoctor:id/pwd")).sendKeys("88888");
        driver.findElement(By.id("com.testgroup.testdoctor:id/login")).click();
        String toast = "请输入密码";
        try {
            final WebDriverWait wait = new WebDriverWait(driver, 3);
            Assert.assertNotNull(wait.until(ExpectedConditions.presenceOfElementLocated(By.xpath(".//*[contains(@text,'" + toast + "')]"))));
            log.info("查找toast成功!");

        } catch (Exception e) {
            throw new AssertionError("找不到" + toast);
        }


    }


}

最后的解决办法是修改登录方法, 根据automationName的值修改i登录方法:

public void logonAsUser(String username, String password)throws IOException{
        input_username_field(username);
        if(driver.getCapabilities().getCapability("automationName").equals(AutomationName.ANDROID_UIAUTOMATOR2)){
            password_field.click();
            Runtime.getRuntime().exec("cmd /c adb shell input keyboard text "+ password);
        }else {
            input_password_field(password);
        }
        tap_login_button();
    }

现在可以登录成功了, 但是很快, 其他需要输入文本的地方又报错了.

请大神们指点

480

https://github.com/appium/appium/issues/8609

UIAutomator2 is incompatible to Android versions below 5 (Lollipop). Please use some other backend for these.
