slf4j-android fixed

Tired of slf4j-android not logging your debug messages? Tired of android logger hiding your UnknownHostException or other exceptions not appearing? Use this instead of the built-in slf4j-android logger.

Features

• Shows DEBUG messages during the development: http://jira.qos.ch/browse/SLF4J-314
• Does not hide any exceptions, even exceptions hidden by buggy Android Studio 1.5. Fixes https://code.google.com/p/android/issues/detail?id=195164 https://code.google.com/p/android/issues/detail?id=194446 http://stackoverflow.com/questions/28897239/log-e-does-not-print-the-stack-trace-of-unknownhostexception
• Supports Crashlytics; when Crashlytics is enabled for your project handroid will log using Crashlytics.log and Crashlytics.logException instead.

Using with your project

You do not need to install anything, just check out the sources and run

$ ./gradlew

This will install the slf4j-handroid library into your local m2 repository. Then, just add the following gradle dependency to your Android project:

repositories {
  ...
  mavenLocal()
}
dependencies {
  compile 'sk.baka.slf4j:slf4j-handroid:1.7.25'
}

Then, just update the HandroidLoggerAdapter.DEBUG field to appropriate value. Good practice is to log debug during development, while not logging debug messages during production. You can achieve this by adding a constructor to your android.app.Application and:

HandroidLoggerAdapter.DEBUG = BuildConfig.DEBUG;

Then, replace all calls to Android built-in Log class by slf4j logging, for example:

public class YourClass {
  private static final Logger log = LoggerFactory.getLogger(YourClass.class);
  public void foo() {
    log.error("Something failed", new RuntimeException("something"));
  }
}
