Android Log how we use them . Log.v(), Log.d(), Log.i(), Log.w(), Log.e()

Basically Log are 5 kinds of Log those are describe in details:- 

Log.v(); // Verbose

Log.d(); // Debug

Log.i(); // Info

Log.w(); // Warning

Log.e(); // Error

Where
Log.v(String,String);
Log.d(String,String);
Log.i(String,String);
Log.w(String,String);
Log.e(String,String);

Log.e: This is for when bad stuff happens. Use this tag in places like inside a catch statement. You know and error has 

occurred and therefore you're logging an error.

Log.w: Use this when you suspect something shady is going on. You may not be completely 

in full on error mode, but maybe you recovered from some unexpected behavior. Basically,

 use this to log stuff you didn't expect to happen but isn't necessarily an error. Kind 

 of like a "hey, this happened, and it's weird, we should look into it."

Log.i: Use this to post useful information to the log. For example: that you have 

successfully connected to a server. Basically use it to report successes.

Log.d: Use this for debugging purposes. If you want to print out a bunch of messages

 so you can log the exact flow of your program, use this. If you want to keep a log of variable values, use this.

Log.v: Use this when you want to go absolutely nuts with your logging. If for some 

reason you've decided to log every little thing in a particular part of your app, use the Log.v tag.
