Question

I am new in android and i print log-cat using:

Log.w("Tag", "String text");

and log text print but after searching for a time i find some more way to print logcat like:

Log.v() 
Log.d()

and now i am confuse in these methods.

Which is the best method for print log-cat and how may method for print lagcat and also what is the main difference between them?

Answer 1

commonly used Log methods are five :

Log.v () VERBOSE

Log.d () DEBUG

Log.i () INFO

Log.w () WARN

Log.e () ERROR

1: Log.v – debugging color black , and any messages will be output, where v represents the verbose verbose mean, usually is Log.v (“”, “”);

2: Log.d – the output color is blue , the only output debug debugging meaning, but he would output the upper filter up through of DDMS Logcat label to select.

3: Log.i – output color is green , general tips, news information, it does not the output Log.v Log.d information, but will display the information of i, w and e

4: Log.w – mean orange , can be seen as a warning The warning, in general we need to optimize the Android code, and will output it after Log.e.

5: Log.e – is red , you can think of error error here only to show the red error message, these errors we need careful analysis.
