Remarks

Definition

Logcat is a command-line tool that dumps a log of system messages, including stack traces when the device throws an error and messages that you have written from your app with the Log class.

When to use

If you are considering using Java’s System.out methods for printing to the console instead of using one of Android’s Log methods, then you should know that they basically work the same. However, it is better to avoid using Java’s methods because the extra information and formatting provided by Android’s Log methods are more beneficial. Also, the System.out print methods are redirected to the Log.i() method.
