将 adb logcat 与真实手机(而不是模拟器)一起​​使用 [英] Using adb logcat with a real phone (and not the emulator)

问题描述

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).它还显示了在执行过程中发生的异常的堆栈跟踪.

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.

但是，当我使用真正的手机时，adb logcat"不执行/不显示任何内容.

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

我也试过adb -d logcat"，它也没有显示任何内容.

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

有什么办法让它在真机上运行吗?

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

谢谢.

更新:

我刚刚尝试了adb -s ? logcat"('?' 是设备的序列号)，也没有结果.

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

我尝试了另一个adb"命令来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.

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.

推荐答案

1. 在您的设备上启用 USB 调试.

1. Enable USB debugging on your device.

将设备连接到计算机

使用这些命令:

获取设备 ID"

adb devices

示例:

$ adb devices
List of devices attached
5856423841563398    device
emulator-5554   device

使用logcat时指定设备

To specify the device when using logcat

adb -s "device id" logcat

示例:

$ adb -s 5856423841563398 logcat
--------- beginning of crash
03-31 15:56:51.174 13547 13547 E AndroidRuntime: FATAL EXCEPTION: main
