Suppose, an application of about 10000 lines of code gets an error. So, in that 10000 line codes, to detect the error Logcat helps by displaying the error messages. • Errors in different modules and methods can be easily detected with the help of the LogCat window

  3. Using Using LogCat LogCat window window • The LogCat prints an error using a Log Class. The class which is used to print the log messages is actually known as a Log Class.
