记⼀次appium识别toast问题解决经历
经查询appium1.6.3以上才能识别toast，之前安装appium版本是1.4.X，于是重整了测试环境，这篇后半部分有记录
官⽅⽂档是这么说的
Firstly you should install appium server. . The version 1.6.3 or greater is recommended.
Since version 5.x there many features based on Java 8. So we recommend to install JDK SE 8 and provide that source compatibility.
也就是更新appium 到1.6.3以上，java-client版本最好是5.x，jdk要⽤1.8、selenium要⽤3.x，其他版本不⼀定兼容，要⾃⼰亲测是否可⽤根据要求重整环境如下：
appium：1.6.3
UiAutomator2 Drvier: 0.2.3
java-client ：5.0.0-BETA6
selenium：3.3.1
jdk：1.8
sdk：4.4.2
想识别toast，官⽹是这么说
capabilities.setCapability(MobileCapabilityType.AUTOMATION_NAME, AutomationName.APPIUM);
You have to define this automation type to be able to use Android UIAutomator2 for new Android versions
capabilities.setCapability(MobileCapabilityType.AUTOMATION_NAME, AutomationName.ANDROID_UIAUTOMATOR2);
我⼿机系统是6.0,sdk版本UIAutomator2，加上这句
capabilities.setCapability(MobileCapabilityType.AUTOMATION_NAME, AutomationName.ANDROID_UIAUTOMATOR2);
运⾏后⼿机会装如下两个apk
io.appium.uiautomator2.server
io.appium.st
启动driver代码如下：
[java]
1.        protected AndroidDriver<WebElement> driver;
2.
3. @Parameters({ "serverIP","port", "platformName","udid",
4.        "appPackage", "appActivity" })
5. @BeforeTest
6. public void setUp(String serverIP,String port,String platformName,String udid,
7.          String appPackage,String appActivity) throws Exception {
8.    DesiredCapabilities capabilities = new DesiredCapabilities();
9.    capabilities.setCapability(CapabilityType.BROWSER_NAME, "");
10.    capabilities.setCapability("platformName", platformName);
11.    capabilities.setCapability("deviceName", udid);
12.    capabilities.setCapability("udid", udid);
13.    capabilities.setCapability("platformVersion", "6.0");
14.    capabilities.setCapability("unicodeKeyboard", true);
15.    capabilities.setCapability("resetKeyboard", true);
16.    capabilities.setCapability("noReset", true);
17.    capabilities.setCapability("noSign", true);
18.    capabilities.setCapability("appPackage", appPackage);
19.    capabilities.setCapability("appActivity", appActivity);
20.    capabilities.setCapability("automationName","uiautomator2");//调⽤uiautomator2，获取toast
21.
22.    driver = new AndroidDriver(new URL("" + serverIP + ":" + port + "/wd/hub"),
23.            capabilities);
24.      }
识别toast代码：
[java]
1. final WebDriverWait wait = new WebDriverWait(driver,3);
2. Assert.assertNotNull(wait.until(ExpectedConditions.presenceOfElementLocated(By.xpath(".//*[contains(@text,'"+ toast + "')]"))));
unicode keyboard download
3. log.info("查toast成功！");
4. return true;
5. } catch (Exception e) {
6. throw new AssertionError("不到"+toast);
运⾏后driver初始化失败，也没有装如上所说的两个apk，去掉这句

看这个报错信息有点蒙，服务⽇志⼀句⼀句跟下来，发现这句

额，原来是sdk没这个⼯具，没办法进⾏ Zip-aligning apk，然后安装。所以报错，很是欣喜，然后⽤36
0⼿机助⼿⼿动安装了这两个apk到⼿机，再次运⾏，⼀直在等待uiautomator2，最后超时报错，说明uiautomator2 server没起来

百度相关信息特别少，只能查官⽹，按官⽹所说我的配置，代码都没问题。查单元测试源码，也证明这样做是对的，后来怀疑，appium版本与java-client,selenium版本不兼容，前前后后换了好⼏个版本，整了好⼏天，还是不⾏，最后也排除了这⼏个版本兼容性，最后更新了sdk，最⾼⽀持> POST /wd/hub/session/be19a6ec-33b4-49c2-a209-b6e7fd8ad9ce/elements {"

最后针对这次问题的解决过程，⼜做了重新梳理，最后得出结论是io.appium.uiautomator2.server、io.appium.st这两个apk,⼀定要进⾏Zip-aligning apk，然后再安装，才能正常使⽤，⼿动安装不⾏，跟sdk版本是否更新到6.0⽆直接关系，中间踩了好⼏个坑，费了好⼏天时间。⼤家可以借鉴⼀下，有什么问题，也可以留⾔，⼤家⼀起讨论。
