Android开发abd相关异常：Adb connection Error:远程主机强迫关闭了一个现有的连接
本文主要解决adb connection error的问题——reset adb.
环境为真机测试，偶尔会报如下错误
Java代码

之前都是重启eclipse解决，但偶尔还解决不了。对于真机需要拔掉数据线，关闭eclipse重启，重新连接手机解决。
但由于eclipse实在过于笨重，关闭重启时间过长。找到另外一种解决方法：
eclipse中视图模式选择DDMS(还有常见的java和debug视图)， 显示Devices窗口，若无可通过选择window->show view->Devices显示，再选择下拉箭头中的reset adb。
此时eclipse会再自动重试一次，输入Connection attempts：1即表示成功啦
