调试appium程序问题过程中，出现如下异常

根据提示的异常信息提到junit、java-client、selenium-java、selenium-sever，以及网上搜索到的资料，可能是最原始的类库，也即junit、java-client、selenium-java、selenium-sever这几个jar文件导致的，那么我们现在要排除的就是对这几个文件的版本进行尝试更换，看看是否有异常信息改变或者改善，果然在进行更换selenium-java-2.44.0版本到selenium-java-2.6.0时，在运行脚本时，异常信息发生改变，如下

并且，此时，控制台有异常提示
三月 21, 2018 5:19:43 下午 org.openqa.selenium.remote.ProtocolHandshake createSession
信息: Attempting bi-dialect session, assuming Postel's Law holds true on the remote end
同时，在appium server端提示：如下
> info: Client User-Agent string: Apache-HttpClient/4.5.2 (Java/1.8.0_74)
> error: The following desired capabilities are required, but were not provided: platformName
> info: [debug] Got configuration error, not starting session

...
这里给的提示是，创建session失败，因为desired capabilities的属性platformName需要但没有提供。此处，基本可以说明，初步的问题已经基本得到解决，但也可能只是表面上，提示不同而已，并没有真正解决，我们暂且把它视为已解决。但同时也出现后面提示的错误，那我们再次尝试加上capabilities的platformName属性，代码如下
capabilities.setCapability("platformName", "Android");
然后再次尝试运行Junit Test，依然出现创建session失败问题，但此时appium server提示信息已经改变，如下
> info: [debug] Responding to client with error: {"status":33,"value":{"message":"A new session could not be created. (Original error: Bad app: E:\\eclipseWorkspace\\TestDemo\\apps\\RandomContant.apk. App paths need to be absolute, or relative to the appium server install dir, or a URL to compressed file, or a special app name. cause: Error: Error locating the app: ENOENT, stat 'E:\\eclipseWorkspace\\TestDemo\\apps\\RandomContant.apk')","origValue":"Bad app: E:\\eclipseWorkspace\\TestDemo\\apps\\RandomContant.apk.

...
意思是说，app的路径错误，然后我对其他能正常运行的脚本进行对比，如：
可正常运行的脚本为
public class CalculatorTest {
public static void main(String[] args) throws MalformedURLException, InterruptedException {
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("deviceName", "8SHQ31206614HB2078X");
capabilities.setCapability("automationName", "Appium");
capabilities.setCapability("platformName", "Android");
capabilities.setCapability("platformVersion", "7.0");
capabilities.setCapability("appPackage", "com.android.calculator2");
capabilities.setCapability("appActivity", ".Calculator");
AppiumDriver driver = new AppiumDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
driver.findElement(By.name("1")).click();
driver.findElement(By.name("5")).click();
driver.findElement(By.name("9")).click();
driver.findElement(By.name("delete")).click();
driver.findElement(By.name("+")).click();
driver.findElement(By.name("6")).click();
driver.findElement(By.name("=")).click();
Thread.sleep(2000);
String result = driver.findElement(By.id("com.android.calculator2:id/formula")).getText();
System.out.println(result);
driver.quit();
}
}
异常运行脚本为
public class ContactsTest
{
/**

* TODO(这里描述这个方法适用条件 – 可选)

private AppiumDriver driver;
@Before
public void setUp()
throws Exception
{
// set up appium
File classpathRoot = new File(System.getProperty("user.dir"));
File appDir = new File(classpathRoot, "/apps");
File app = new File(appDir, "RandomContant.apk");
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("deviceName", "0123456789ABCDEF");
capabilities.setCapability("platformName", "Android");
capabilities.setCapability("platformVersion", "7.0");
capabilities.setCapability("app", app.getAbsolutePath());
// capabilities.setCapability("app", "E:\\eclipseWorkspace\\TestDemo\\apps\\RandomContant.apk");
capabilities.setCapability("appPackage", "bbk.cly.RandomContacts");
capabilities.setCapability("appActivity", ".RandomContacts");
driver = new AppiumDriver<>(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
System.out.println("App is launched!");
}

*/
@After
public void tearDown()
throws Exception
{
driver.quit();
}
@Test
public void test()
{
WebElement el = driver.findElement(By.name("生成"));
el.click();
System.out.println("App is done!");
// fail("Not yet implemented");
}
}
通过前后对比路径的代码，发现可正常运行的脚本，并不需要初始化设置app路径，也即没有
File classpathRoot = new File(System.getProperty("user.dir"));
File appDir = new File(classpathRoot, "/apps");
File app = new File(appDir, "RandomContant.apk");
capabilities.setCapability("app", app.getAbsolutePath());
这部分的代码，那么去掉这部分的代码，进行尝试，果然脚本已经开始可以运行，但，最后还是失败了，提示如下
注：为何不需要设置app路径？
> info: [debug] Responding to client with error: {"status":33,"value":{"message":"A new session could not be created. (Original error: Could not find a connected Android device.)","origValue":"Could not find a connected Android device."},"sessionId":null}
这里意思是无法连接上设备，我们知道，appium连接设备，是通过adb来连接的，那我们尝试在命令提示符cmd里输入adb devices连接
C:\Users\xxxxxxxx>adb devices
List of devices attached
0123456789ABCDEF device
然后再次运行脚本，又提示以下错误，似乎有电脑，一波N折，appium server提示如下：

> info: [debug] Getting all processes with 'uiautomator'

此处提示uiautomator进程出现问题，而uiautomator这个东西存在于SDK里面，这个SDK是公司为了某个自动化工具定制的，这让我们怀疑，这SDK是否出现了问题？当然这只是一个疑问。
而这里的关键信息是bad pid 'uiautomator'，经过一番搜索后，得到：
Appium 1.4.13在Android 7上有bug，报错：
Failure [INSTALL_FAILED_ALREADY_EXISTS: Attempt to re-install io.appium.settings without first uninstalling.]
原解决方案见：https://discuss.appium.io/t/support-version-android-n/10206/5
总结自己的解决方案：
原因:
1. adb.js 中1035 行this.shell("ps '" + name + "'", function (err, stdout) {
对应执行的指令是ps 'uiautomator', Android7不支持这个指令格式，所以执行结果是bad pid 'uiautomator'
目前Appium未对此进行处理,所以需要修改此指令的执行方式
即将 Appium\node_modules\appium\node_modules\appium-adb\lib\adb.js 文件修改
this.shell("ps '" + name + "'", function (err, stdout) {
...
var procs = [];
var outlines = stdout.split("\n");
outlines.shift() //添加这行
...
于是再进行调试，好吧，还是有问题，出现了如下错误
> info: [debug] Responding to client with error: {"status":33,"value":{"message":"A new session could not be created. (Original error: Activity used to start app doesn't exist or cannot be launched! Make sure it exists and is a launchable activity)","origValue":"Activity used to start app doesn't exist or cannot be launched! Make sure it exists and is a launchable activity"},"sessionId":null}
网上很多说法是：“要打开的activity不存在，activity路径错误，改为完整正确的activity路径”
仔细检查了好几遍发现，activity是存在的，activity路径也是正确的（当然这么低端的问题一般人也不会犯）
经过一番查找，问题解决如下：
注释掉setup中的如下两行：
capabilities.setCapability("appPackage", "xxx.xxx.xxx.activity");
capabilities.setCapability("appActivity", ".MainActivity");
但，如果前面没有添加app路径的话，会报No app set的错误，需要设置app路径，如我是：
File classpathRoot = new File(System.getProperty("user.dir"));
File appDir = new File(classpathRoot, "/apps");
File app = new File(appDir, "xxx.apk");
...
capabilities.setCapability("app", app.getAbsolutePath());
再次运行，问题解决了。
然而，在自己电脑上Android 7.0上运行脚本的时候，又出现了如下问题
> info: [debug] Responding to client with error: {"status":33,"value":{"message":"A new session could not be created. (Original error: Command failed: C:\\Windows\\system32\\cmd.exe /s /c \"\"D:\\Program Files (x86)\\Android\\android-sdk\\platform-tools\\adb.exe\" -s emulator-5556 install \"D:\\Program Files (x86)\\Appium\\node_modules\\appium\\build\\settings_apk\\settings_apk-debug.apk\"\"\nadb: failed to install D:\\Program Files (x86)\\Appium\\node_modules\\appium\\build\\settings_apk\\settings_apk-debug.apk: Failure [INSTALL_FAILED_ALREADY_EXISTS: Attempt to re-install io.appium.settings without first uninstalling.]\r\n)","killed":false,"code":1,"signal":null,"cmd":"C:\\Windows\\system32\\cmd.exe /s /c \"\"D:\\Program Files (x86)\\Android\\android-sdk\\platform-tools\\adb.exe\" -s emulator-5556 install \"D:\\Program Files (x86)\\Appium\\node_modules\\appium\\build\\settings_apk\\settings_apk-debug.apk\"\"","origValue":"Command failed: C:\\Windows\\system32\\cmd.exe /s /c \"\"D:\\Program Files (x86)\\Android\\android-sdk\\platform-tools\\adb.exe\" -s emulator-5556 install \"D:\\Program Files (x86)\\Appium\\node_modules\\appium\\build\\settings_apk\\settings_apk-debug.apk\"\"\nadb: failed to install D:\\Program Files (x86)\\Appium\\node_modules\\appium\\build\\settings_apk\\settings_apk-debug.apk: Failure [INSTALL_FAILED_ALREADY_EXISTS: Attempt to re-install io.appium.settings without first uninstalling.]\r\n"},"sessionId":null}
原因是，Appium 1.14不完全兼容Android 7.0，之前在公司的电脑上可以正常运行Android 7.0的机器，但用自己电脑运行另一台Android 7.0的机器，就出现如上所示的异常。
解决方法是，把测试机换成Android 6.0的机器，另外一种解决办法是，升级Appium 1.14到1.72版本，但这个解决方法尚未实验。
说明：运行测试的时候我们不需要指定package和activity 这些信息，Appium会从apk中提取这些信息。
见：https://github.com/appium/appium/issues/2981 中paymand 的解释：
Don't know about the apk info tool above, but you can always get that info using the aapt tool from Android SDK with the following command:
`adt/sdk/build-tools/android-4.4/aapt dump badging app.apk` Note: You shouldn't need to specify appPackage, appActivity, etc. since Appium should be able to extract those from the apk using the method above anyway.

到此，初步运行的问题已经基本解决，文章有点长，本人才浅，欢迎指出不当指出。
