android - Android 中的主日志是什么？

Question

android中的主日志是什么？它的作用是什么。只知道adb logcat -b main可以查看主日志。有人可以对此做更多解释吗？

Answer 1

主日志缓冲区包含日志条目，例如来自使用 android.util.Log 编写它们的应用程序.

其他日志缓冲区(事件、 radio )包含来自平台的低级别日志信息。

来自documentation :

The Android logging system keeps multiple circular buffers for log messages, and not all of the log messages are sent to the default circular buffer. To see additional log messages, you can run the logcat command with the -b option, to request viewing of an alternate circular buffer. You can view any of these alternate buffers:

• radio — View the buffer that contains radio/telephony related messages.
• events — View the buffer containing events-related messages.
• main — View the main log buffer (default)
