Using adb logcat with a real phone (and not the emulator)
提问by MyName
when I'm using the Android emulator I can do "adb logcat" to see output messages (log / system.out.println) originated from my code. It also shows the stack trace of exceptions which happen during execution.
当我使用 Android 模拟器时，我可以执行“adb logcat”来查看源自我的代码的输出消息（log/system.out.println）。它还显示了在执行期间发生的异常的堆栈跟踪。
But, when I'm using a real phone, "adb logcat" does not do / show anything.
但是，当我使用真正的手机时，“adb logcat”不会做/显示任何事情。
I also tried "adb -d logcat" which also does not display anything.
我也试过“adb -d logcat”，它也没有显示任何内容。
Is there any way to get it working with the real phone?
有没有办法让它与真正的手机一起工作？
Thanks.
谢谢。
UPDATE:
更新：
I just tried "adb -s ? logcat" ('?' is the serial number of the device) and also got no results.
我刚刚尝试了“adb -s ? logcat”（'?' 是设备的序列号），但也没有结果。
I tried another "adb" command to see if anything was working: "adb -s ? bugreport". This printed a lot of stuff. Example: "Memory Info", "CPU Info" and some Java specific things. So it seams that some stuff is working.
我尝试了另一个“adb”命令以查看是否有任何工作：“adb -s ? bugreport”。这打印了很多东西。示例：“内存信息”、“CPU 信息”和一些 Java 特定的东西。所以看起来有些东西正在起作用。

Enable USB debugging in your device.
Connect device to computer
Use this commands
在您的设备中启用 USB 调试。
将设备连接到计算机
使用这个命令
--> $adb devices (will give the "device id" that is connected) output ex. 82990AB830201D device
--> $adb devices（将给出连接的“设备ID”）输出例如。82990AB830201D 装置
--> $adb -s "device id" logcat (you will be able to see your device logcat)
--> $adb -s "device id" logcat (你将能够看到你的设备 logcat)
ex $adb -s 82990AB830201D logcat
前 $adb -s 82990AB830201D logcat
I follow this steps and it works good.

Get list of devices:
adb devices
获取设备列表：
亚行设备
You will get this:
你会得到这个：
List of devices attached
emulator-5554 device
0123456789ABCDEF device
Run log with parameters like this:
adb -s "0123456789ABCDEF" logcat MyTag:D *:S
使用如下参数运行日志：
adb -s "0123456789ABCDEF" logcat MyTag:D *:S
where "MyTag" is tag used in Log.d("MyTag", value) or you will get too many text.
其中 "MyTag" 是 Log.d("MyTag", value) 中使用的标签，否则你会得到太多文本。

On the windows command/Linux shell, issue the command below,
在 windows 命令/Linux shell 上，发出以下命令，
adb devices
if the device is not listed in result, then install "APK installer", which can help install the adb driver in your windows machine. Link is below:
如果结果中未列出该设备，则安装“APK 安装程序”，它可以帮助在您的 Windows 机器中安装 adb 驱动程序。链接如下：

Check the listing again with the command above in the shell/cmd, and if the device is listed then Log Cat will surly work.
在 shell/cmd 中使用上面的命令再次检查列表，如果设备被列出，那么 Log Cat 将正常工作。
After that you can try:

adb -d logcat

You probably need to activate logging on your mobile device too.
您可能还需要在移动设备上激活登录。
In the case of my Huawei device, I need to enter the phone number: ##2846579##
在我的华为设备的情况下，我需要输入手机号码： ＃＃2846579＃ ＃
to get into a service menu. From there I could activate logging. Not sure what device you are using, but probably there is some service menu there too.
进入服务菜单。从那里我可以激活日志记录。不确定您使用的是什么设备，但那里可能也有一些服务菜单。
Once done, reboot and try again with adb -d logcat
完成后，重新启动并使用 adb -d logcat 重试

Emulators are named like emulator-5554etc. If your device is properly installed you should see it too. The name depends on which manufacturer you are using.
模拟器的名称类似于emulator-5554等。如果您的设备安装正确，您也应该看到它。该名称取决于您使用的制造商。
If you don't see your device, the drivers are not installed correctly. Do some searches for "adb install drivers" on Google. Here's a hit that might do it for you: http://forum.xda-developers.com/showthread.php?t=502010
