什么是Java的console.log()? [英] What's the console.log() of java?

问题描述

我正在开发一个Android应用，我想知道最好的调试方法是像javascript中的console.log一样进行调试

I'm working on building an Android app and I'm wondering what the best approach is to debugging like that of console.log in javascript

推荐答案

Log 类:

用于发送日志输出的API.

API for sending log output.

通常，使用Log.v() Log.d() Log.i() Log.w()和Log.e() 方法.

Generally, use the Log.v() Log.d() Log.i() Log.w() and Log.e() methods.

详细程度从最小到最大的顺序是ERROR，WARN， INFO，DEBUG，VERBOSE.详细信息绝不能编译为 应用程序，开发期间除外.调试日志已编译但 在运行时被剥离.错误，警告和信息日志将始终保留.

The order in terms of verbosity, from least to most is ERROR, WARN, INFO, DEBUG, VERBOSE. Verbose should never be compiled into an application except during development. Debug logs are compiled in but stripped at runtime. Error, warning and info logs are always kept.

在Android之外，使用System.out.println(String msg).

Outside of Android, System.out.println(String msg) is used.
