Arrow Logger – Log louder than everyone else

Recently I’ve been playing round with a few libraries that people share based upon an api or service that they offer. These libraries offer access to data in a controlled way and more often than not require authorisation to use.
When I’ve picked up the library I just want to start coding straight away and I don’t think about the authorisation or giving an api key, but then when I’ve written some code and run my app .. nothing, it doesn’t work. This is usually down to a missing api key or some other simple command that I’ve missed. Searching the logs for what seems like hours there is a tiny single line saying something like “unknown api key”.
So I thought hey! Wouldn’t it be great if these libraries could inform you of the correct use in a more prominent, louder way. What if the whole LogCat window was dedicated to saying “DUH YOU DIDN’T ADD THE API KEY – I NO WORK FOR YOU”.
Introducing ArrowLog your friendly, obnoxious LogCat spammer. ArrowLog isn’t for everyone you wouldn’t want every message logged this way so please use some common sense & ship it with all your apps.

Simple api use is like so:

ArrowLog.log("Spamming your LogCat YOLO");

Which results in the awesomeness:


If you want to get down and dirty and really take pleasure in how you spam LogCat you can have more control with the ProArrowLog:

			.log("Giant Arrows in yo face!")

The creates a log with 6 arrows that are 8 characters tall, logging with Log.e:


Disclaimer: ProArrowLog is only for pro’s if the arrows don’t come out as you expect: you’re doing it wrong

ArrowLog is available now from JCenter (that’s the default repository for Android apps).
You can add it to your project like so

repositories {

dependencies {
	compile 'com.blundell:arrow-log:1.1.0'

ArrowLogger is open source and available here for your forking pleasure.

For contributors, a little about the code? ArrowLogger is split into two modules, one is pure java and the other Android. The arrow-logger (Android) module only looks after printing by LogCat and has the user facing api. The arrow-core (Java) module is where the magic happens, checkout to see how the arrows are generated, they are calculated line by line and added to a list of logs.

Pull requests for new logging shapes like squares, spears & shamrocks are more than welcome!
