Ok, I don't know if i got "the" answer. but here is how I've solved the same issue on my environnement ( Windows 8/Android Studio, but same error with ADT or eclipse) :

好吧，我不知道我是否得到了答案。但是，我在我的环境中解决了同样的问题(Windows 8/Android Studio，但与ADT或eclipse相同的错误):

Context of my issues :

I've got an Asus PC, and with all the application suite installed by default. So I've found that one of this Asus app ( currently "Asus sync") was using adb and in fact, it was taking control of the emulator over my adb in the AndroidSDK directory.

我有一个Asus PC，以及默认安装的所有应用程序套件。所以我发现这个Asus应用程序(目前“Asus sync”)使用的是adb，事实上，它是在AndroidSDK目录中对我的adb的仿真器进行控制。

How to fix as a PC user :

Go to Task manager ( right click on task bar) , and look for "adb.exe" . Then right click on it and select "Open the directory". This will bring you to the responding adb. In my case it was Asus Sync, so I just had to unistall this software and everything works fine !

到任务管理器(右击任务栏)，寻找“adb”。exe”。然后右击它并选择“打开目录”。这将为您带来相应的adb。在我的例子中，它是Asus Sync，所以我只需要使用unistall这个软件，一切都没问题!

How to fix as a Mac user :

Go to Activity Monitor (/Applications/Utilities/), and look for "adb". Then try to kill the process. Then look if it solve your "Connection refused" in Android studio/ADT or eclipse

去活动监视器(/应用程序/实用程序/)，寻找“adb”。然后试着杀死这个过程。然后看看它是否能解决Android studio/ADT或eclipse中“拒绝连接”的问题。

If still not working you can try :

• Start a emulator ( with your AVD manager)
• 启动模拟器(使用AVD管理器)
• when finished loading, Open DDMS panel (in android studio : Menu Tools > Android > Monitors DDMS)
• 完成加载后，打开DDMS面板(在android studio中:菜单工具> android >监控DDMS)
• Look if you see your current running android emulator ( listed on the Device panel)
• 查看当前运行的android模拟器(在设备面板上列出)
• See if this line is kind of "flashing" ( connect/disconnect).
• 看看这条线是否有点“闪烁”(连接/断开)。
• If so, you have probably a other adb instance running in conflict
• 如果是这样，您可能有另一个在冲突中运行的adb实例。
• If not, you can restart adb or reinstall your SDK
• 如果没有，您可以重新启动adb或重新安装您的SDK。

Hope this could help someone !

This issue occurs when Android Debug Bridge aka ADB is not responding to the request from Android Studio. I killed the process adb.exe and started it again. This solved my problem.

这一问题发生在Android调试桥卡亚行没有响应来自Android Studio的请求时。我杀了亚开行。exe又开始了。这解决了我的问题。

If you are using a real device :

如果你使用的是真实设备:

Just reconnect your device, make sure your cable are workable and you installed the proper drivers.

只要重新连接你的设备，确保你的电缆是可行的，你安装了合适的驱动程序。

For me the following worked(after I tried the above points mentioned by others):

对我来说，接下来的工作(在我尝试了别人提到的几点之后):

1. I tried debugging/running anther application. It was okay. So this pointed me to the direction that the current application has some problem
2. 我尝试调试/运行另一个应用程序。这是好的。这就指向了当前应用程序存在问题的方向。
3. if (point 1 == true) {I uninstalled the application from my phone manually }
4. 如果(point 1 == true){我从我的手机手动卸载应用程序}

Then re-make/rebuild the application and debug/run worked

然后重新生成/重新构建应用程序和调试/运行工作。
