Eclipse没法链接真机 并不是ADB被占用 缘由 很2 已解决 记录之

最近一直忙着考试的事情，而后找工做，找实习，找钱啊。对于Android我抱有很大的梦想，现实是残酷的。

 

OK，上面纯粹扯蛋了。今天手机链接电脑，打开USB调试，理论上就应该链接eclipse成功，能够在手机上直接测试开发中的项目。可是问题来了，怎么弄都没有反应。

 

什么叫怎么弄都没反应，我尝试了百度中的全部方法：

1. 重启adb,不管是工具中的Reset adb，亦或是cmd中的adb kill-server而后adb start-server，eclipse的Devices中始终没有手机的身影。
2. 豌豆荚占用端口、腾讯tadb占用端口等问题亦不存在，经过cmd命令 netstat -aon|findstr "5037"，查询全部占用5037的端口，adb好端端的占用着，并不存在占用的问题，因此并非我这里的解决办法。

OK，实在不能忍了，我就去了stackoverflow，已search发现有人的状况和我是同样的。引用一下原文，我才发现本身并无深刻的去理解本身的问题所在：

I don't want to debug my Android apps on emulator (Android Virtual Device) anymore. Instead, I want to debug it on my phone. My phone is LG Optimus L7 P700.
I already have downloaded USB Driver for my phone from official LG support web site. On my AVD Manager: Google USB Driver is also installed. Also, I ticked my Settings > Developer options-> USB debugging on my phone to be enabled. I connected my phone via USB cable, but I have problem now. When I run adb devices command on my command prompt as mentioned on tutorials I found on Google, my list of attached devices is empty, as u can see below in screenshoot. Here is screenshoot of my command prompt: http://i.imgur.com/J43CDqs.jpg

Also when I go to My Computer->Manage, my phone have yellow exclamation point, I dont know why ? Here is screenshoot: http://i.imgur.com/cfna7ds.jpg

最终我发现，原来是个人Nexus 4驱动未装好，这里我就要纳闷了，我驱动没有装好，我也能够传各类文件么。。。额，求科普。并且个人驱动没法自动搜索，迫使我从网上下载安装，而后终于在Eclipse中看到了个人手机。OH MY GOD. HOLLY SHIT!

另外这里还有一个解决办法，放在这里，算是大杀器吧，理论上能够通杀非1，2方法的问题。

这里也是引用的别人的话，凑活看吧，比较好理解，就是删了重装。

this is tricky sometimes. uninstall adb drivers through device manager and re-install them. uninstall all other adb drivers probably installed on your machine first before re-install. after installation connect your phone and choose driver-path manually. this is always the biggest pain for me with android development, I wasn`t able to connect one of my devices at all.

缘由找到了，以为本身很2.唉，有木有，专业开发20年，也会犯这种错误么。。。
