Just wanted to say that I have taken the time and published my Android logger AppLog on The Central Repository.

You can include it as a dependency like this in your build.gradle:
dependencies {
    compile 'se.marteinn.utils.logging:applog:2.1.2'
}
For anyone interested in publishing libraries to The Central Repository, I recommend reading Publish an aar file to Maven Central with Gradle. I also recommend using gradle-mvn-push for publishing.
