在我使用的是Android模拟器我可以做亚行logcat看到输出消息（日志/的System.out.println）起源于我的code。它也显示了执行过程中发生的异常的堆栈跟踪。

但是，当我使用的是真正的手机，亚行logcat不做/显示任何东西。

我也试过亚行-d logcat的，这也不会显示任何内容。

有没有办法得到它与真正的手机正常工作？

感谢。

更新：

我只是想亚行-s？logcat的（？是设备的序列号），也没有得到结果。

我尝试另一种亚行命令，看看什么是工作：亚行-s错误报告。这印了很多东西。例如：内存信息，CPU信息和一些Java具体的事情。因此，接缝有些东西是工作。

启用USB调试到设备中。

连接设备到电脑

使用此命令

- > $ ADB设备（可以提供设备ID已连接）  输出前。 82990AB830201D设备

- > $ ADB -s设备IDlogcat的（你可以看到你的设备的logcat）

前$ ADB -s 82990AB830201D的logcat

我按照这个步骤，它的作品不错。

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.

But, when I'm using a real phone, "adb logcat" does not do / show anything.

I also tried "adb -d logcat" which also does not display anything.

Is there any way to get it working with the real phone?

Thanks.

UPDATE:

I just tried "adb -s ? logcat" ('?' is the serial number of the device) and also got no results.

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.

Enable USB debugging in your device.

Connect device to computer

Use this commands

--> $adb devices (will give the "device id" that is connected) output ex. 82990AB830201D device

--> $adb -s "device id" logcat (you will be able to see your device logcat)

ex $adb -s 82990AB830201D logcat

I follow this steps and it works good.
