Hey everyone, sadly we do not have any libraries this month 🙁 April fools! Nevermind the bad joke, we’re a bit late for that. Not only that we chose the best Android and iOS libraries of the month, but starting this month, we are also writing posts with JavaScript libs! Check it out here:

Have you ever been in a situation where you had to send some data between two activities? And better yet, in a situation where you had to ADD more parameters to an already long Activity starting method? Yeah, we feel you :( Just to ease our pain, here’s ActivityStarter! Simply annotate which arguments you need to send, and you’re all set :D

As developers, our job is not only to make something work the way it’s supposed to, and to make it look nice, but also to make sure it is optimized. Heavy methods and UI blocking tasks often kill our users’ will to use our application, so we should strive to get rid of such issues.

BlockCanaryEx gives us a hand in our quest for app optimization by showing us all the heavy work load being done, and which method was the cause of the costly operations. It’s built as an “extension” to BlockCanary, but presented in more detail, and with a more user friendly UI.

Here at COBE, smiling is what it’s all about! :) So of course we’re on the lookout for libraries that bring a smile to your face! Too many badly thought out puns you say? And you just came for the library… Have a look then:

Hope you’re on the right hand side of it! :)

BUBBLEEEEEES!

Fancy bubbles which you can select :D

There’s nothing more to say about this, just look at the awesome bubbliness, a perfect fit for this spring weather and picnics.

What will stick with you is the awesome animation this library provides for even the simplest of things — switches. Another bad pun eh? We really do try, give us some credit. Anyway, StickySwitch will focus on a part of your app which you might have neglected in the past, and style it up a little bit.
