Tree instances. You can install an instance by calling
Trees should be done as early as possible. The

There are no

Timber's static methods everywhere throughout your app.
Check out the sample app in

Timber ships with embedded lint rules to detect problems in your app.
TimberArgCount (Error) - Detects an incorrect number of arguments passed to a
Timbercall for the specified format string.
Example.java:35: Error: Wrong argument count, format string Hello %s %s! requires 2 but format call supplies 1 [TimberArgCount] Timber.d("Hello %s %s!", firstName); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
TimberArgTypes (Error) - Detects arguments which are of the wrong type for the specified format string.
Example.java:35: Error: Wrong argument type for formatting argument '#0' in success = %b: conversion is 'b', received String (argument #2 in method call) [TimberArgTypes] Timber.d("success = %b", taskName); ~~~~~~~~
TimberTagLength (Error) - Detects the use of tags which are longer than Android's maximum length of 23.
Example.java:35: Error: The logging tag can be at most 23 characters, was 35 (TagNameThatIsReallyReallyReallyLong) [TimberTagLength] Timber.tag("TagNameThatIsReallyReallyReallyLong").d("Hello %s %s!", firstName, lastName); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
LogNotTimber (Warning) - Detects usages of Android's

String.formatused inside of a
Timbercall. Timber handles string formatting automatically.
Example.java:35: Warning: Using 'String#format' inside of 'Timber' [StringFormatInTimber] Timber.d(String.format("Hello, %s %s", firstName, lastName)); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
BinaryOperationInTimber (Warning) - Detects string concatenation inside of a
Timbercall. Timber handles string formatting automatically and should be preferred over manual concatenation.
Example.java:35: Warning: Replace String concatenation with Timber's string formatting [BinaryOperationInTimber] Timber.d("Hello " + firstName + " " + lastName + "!"); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
TimberExceptionLogging (Warning) - Detects the use of null or empty messages, or using the exception message when logging an exception.
