未能通过android模拟器在appium中启动apk文件

Question

我成功地配置了android仿真器，设备按预期显示。另外，我成功地启动了appium服务器，并通过eclipse编写了以下脚本。

当我执行代码is时，返回appium以及eclipse /p控制台中的以下异常：

如果没有任何修复，我尝试执行相同的脚本，但这次它返回了一些不同的异常，如下所示：

谁能帮上忙，问题是什么，根本原因是什么？如何解决这个问题？

Answer 1

两个人都说了同样的话

error: Failed to start an Appium session, err was: Error: Requested a new session but one was in progress
> info: Client User-Agent string: Apache-HttpClient/4.3.2 (java 1.5)
> info: [debug] Error: Requested a new session but one was in progress

服务器中有一个现有会话，正在运行您的模拟器。重新启动服务器，并确保在请求驱动程序对象时没有运行现有会话。

Answer 2

首先，您似乎还没有在.apk文件中定义capabilities文件的路径。例如。

capabilities.setCapability(MobileCapabilityType.APP, "/root/apps/my_app.apk")
capabilities.setCapability(CapabilityType.BROWSER_NAME, "android")

其次，您似乎在ANDROID_HOME环境变量中有错误的值--这应该是您获得build-tools路径错误的原因。
