无法创建新会话。 （原始错误：命令失败：）Appium错误

Question

我正在为Android设备进行自动化测试。 在模拟器中它工作正常。连接到设备时，它创建＆amp;安装unlock.apk到Android设备。之后出现以下错误

我已在下面设置了配置    DesiredCapabilities capabilities = DesiredCapabilities.android（）;         capabilities.setCapability（MobileCapabilityType.BROWSER_NAME，＆＃34;＆＃34;）;

       capabilities.setCapability("deviceName", "Moto C Plus");
    //capabilities.setCapability("deviceName", "ZZ22cdddP9");
    //  capabilities.setCapability("udid", "ZZ22cdddP9");
    capabilities.setCapability("platformVersion", "7.0");
    capabilities.setCapability("platformName", "Android");
    capabilities.setCapability("browserName", "chrome");
    //capabilities.setCapability("Device Id", "xxxxxxxx");
          capabilities.setCapability("app", "D:\\abc.apk");
    capabilities.setCapability("appPackage", "com.s.abc"); 
    capabilities.setCapability("appActivity", "com.s.sn");

Answer 1

谢谢Shiv＆amp;维诺德，

最后解决了那些问题..我把错误的活动名称。所以它被关闭了。通过设置以下功能，它可以正常运行.setCapability（＆＃34; appActivity＆＃34;，＆＃34; com.example.main.LaunchActivity＆＃34;）;

＆＃13;

＆＃13;

capabilities.setCapability("deviceName", "ZZ22cdddP9");
   capabilities.setCapability("platformVersion", "7.0");
   capabilities.setCapability("platformName", "Android");
   capabilities.setCapability("app", "D:\\abc.apk");
   capabilities.setCapability("appPackage", "com.s.abc"); 
   capabilities.setCapability("appActivity", "com.example.main.LaunchActivity");

在初始化appium驱动程序之前添加以下代码。

String cmd = "adb shell getprop ro.build.version.release";

String osVersion=executeCommand(cmd);

if(osVersion.contains("7"))
{
    //uninstall io.appium.settings
    cmd="adb uninstall  io.appium.settings";
    executeCommand(cmd);

    //uninstall io.appium.unlock
    cmd="adb uninstall  io.appium.unlock";
    executeCommand(cmd);

}

public String executeCommand(String cmd)
{
    String commandresponse="";
    try
    {
        Runtime run = Runtime.getRuntime();
        Process proc=run.exec(cmd);
        BufferedReader stdInput = new BufferedReader(new 
                InputStreamReader(proc.getInputStream()));

    BufferedReader stdError = new BufferedReader(new 
            InputStreamReader(proc.getErrorStream()));

    String response=null;
    while ((response = stdInput.readLine()) != null) 
    {
        if(response.length()>0)
        {
            commandresponse=commandresponse+response;
        }
    }

    while ((response = stdError.readLine()) != null) 
    {
        commandresponse=commandresponse+response;

    }
}
catch(Exception e)
{
    e.printStackTrace();
}
//System.out.println(commandresponse);
return commandresponse;

}

Set following capabilities only and try to start appium :
Note : deviceName should be name which we will get using "adb devices" command.

   capabilities.setCapability("deviceName", "ZZ22cdddP9");
   capabilities.setCapability("platformVersion", "7.0");
   capabilities.setCapability("platformName", "Android");
   capabilities.setCapability("app", "D:\\abc.apk");
   capabilities.setCapability("appPackage", "com.s.abc"); 
   capabilities.setCapability("appActivity", "com.s.sn");
