无法在Android Studio中附加调试器-本地主机:8600 java.net.ConnectException [英] Unable to attach debugger in Android Studio - localhost:8600 java.net.ConnectException
问题描述
在手机上运行调试时，我无法在Android Studio中附加调试器.
I cannot attach the debugger in Android Studio while running debug on a phone.
我目前正在使用运行Android 4.4.4的Samsung S4(但已经在各种Android版本上尝试了S5，S6，S7和Moto E手机).当我尝试运行它时出现以下错误之一，它超时:
I’m currently using a Samsung S4, running Android 4.4.4 (but have tried an S5, S6, S7, and Moto E phone on various Android versions). It times out when I try to run it with either of the following errors:
I/System.out:正在发送等待块
W/ActivityThread:应用程序正在端口8100上等待调试器...
I/System.out: Sending WAIT chunk
W/ActivityThread: Application is waiting for the debugger on port 8100...
或
无法打开调试器端口localhost:8600 java.net.ConnectException连接被拒绝"
failed to open debugger port localhost:8600 java.net.ConnectException "connection refused"
然后应用显示:
等待调试器
应用程序(进程)正在等待调试器附加.
强制关闭
Waiting For Debugger
Application (process ) is waiting for the debugger to attach.

我可以成功连接并运行该应用程序，但在运行>调试应用程序>选择已连接的手机>确定后，我无法连接调试器.
I can successfully connect and run the application, I just can’t get the debugger to attach when I do Run > Debug App > select the connected phone > OK.
我已经能够在具有相同手机的其他计算机(Windows和Mac)上以调试方式运行该应用程序.
I have been able to run the app in debug on other computers (both Windows and Mac) with the same phones.
我从调试和在线搜索的时间中尝试了各种方法:
Various approaches I have tried from hours of debugging and online searching:
-
使缓存无效/重新启动Android Studio
Invalidate Caches/Restart Android studio
检查端口8100、8600、8601等上是否有其他运行的东西，当我从bash运行以下命令时，什么也没回来:
Check for anything else running on ports 8100, 8600, 8601, etc., nothing comes back when I run the following from bash:
$ # while Android studio is trying to attach the debugger
$ lsof -i :8100
$ lsof -i :8600
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME

运行工具> Android> Android设备监视器-它显示了我的设备，但在尝试调试应用程序时我无法运行Android设备监视器，它说:将关闭监视器以启用ADB一体化.继续?"我在这里没有发现任何有用的东西.
Run Tools > Android > Android Device Monitor - it shows my device, but I can’t run Android Device Monitor while I’m trying to debug the app, it says, "Monitor will be closed to enable ADB integration. Continue?" I haven’t found anything useful here.
搜索并杀死adb进程
ps aux | egrep '(adb|java)'
... then doing `kill <pid>` or `kill -9 <pid>` if necessary for the found ones
重新启动Android Studio
Restart Android studio
重新启动计算机
从Oracle网站更新Java JDK，但是，我不确定为什么Android Studio仍然会说"JVM:JetBrains s.r.o的OpenJDK 64位服务器VM"
Update Java JDK from the Oracle website—however, I’m not sure why Android Studio still says, "JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o"
完全卸载并重新安装android studio-例如 https://stackoverflow.com/a/18458893/376489-奇怪的是，我认为这只适用于调试器的一次运行，然后再也不行了……
Completely uninstall and reinstall android studio - e.g., https://stackoverflow.com/a/18458893/376489 - weirdly, I think this worked for one run of the debugger and then not again…
尝试运行>将调试器附加到Android Process-这没有帮助
Tried Run > Attach debugger to Android Process - this didn’t help
尝试运行:
~/Library/Android/sdk/platform-tools/adb kill-server &&
~/Library/Android/sdk/platform-tools/adb start-server
尝试取消选中运行">编辑配置">运行/调试配置">如果APK尚未更改，则跳过安装"
Tried unchecking Run > Edit Configurations > Run/Debug Configurations > Skip installation if APK has not changed
检查系统偏好设置>安全性和隐私>防火墙-此功能已关闭
Check System Preferences > Security & Privacy > Firewall - this is turned off
更新1:尝试撤消手机上的权限以及重新启动手机
Update 1: tried revoking permissions on the phone as well as restarting it
更新1:静音所有断点Android Studio
Update 1: muted all breakpoints Android Studio
在我上面添加的详细信息中，可能还有什么问题或其他有意义的想法吗?
Are there any other ideas for what might be going wrong or anything meaningful in the details I added above?
推荐答案
挺尴尬的，但是似乎前段时间我已经在/etc/hosts文件中输入了ip地址来测试localhost，但从未删除过它.我在另一篇文章中找到一条评论，说要检查以下内容是否在您的/etc/hosts中:
Quite embarrassing, but it looks like some time ago I had entered an ip address into my /etc/hosts file to test something as localhost and never removed it. I found a comment on another post saying to check that the following is in your /etc/hosts:
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
注释掉该虚假行后，调试器现在正在运行.鉴于我在该文件中还有十几个其他IP(因此我可以更容易地用一个友好的名称测试远程主机)，我一定不会在底部注意到这一点.我认为一种更简单的方法来验证是否是问题所在是ping localhost并验证它可以解析为127.0.0.1的IP地址，例如
Upon commenting out that spurious line, the debugger is now working. Given I have a dozen or so other IPs in that file (so I can more easily test remote hosts with a friendly name), I must have not noticed this one at the bottom. I think a more foolproof approach to verifying if this is the problem or not is to ping localhost and verify that it resolves to the ip address of 127.0.0.1, e.g.,
$ ping localhost
PING localhost (127.0.0.1): 56 data bytes
这里的其他人也发表了很棒的评论和建议，谢谢！
