错误:在calabash-android中执行reinstall_apps时主机服务未知

Question

我尝试用calabash-android安装test.apk，但总是失败，原因如下。以下是我的步骤：

Calabash-android resign test.apk
calabash-android build test.apk
calabash-android gen
calabash-android console test.apk
reinstall_apps

并且遇到了下面的错误，有谁可以帮助指导一下问题在哪里？谢谢。

如果你已经过了这一步，很抱歉给你带来不便。

Answer 2

我刚刚发现原因是Android studio占用了阻止calabash-android操作的端口"5037“。

使用端口5037的过程刚刚结束。

THanks all。
