Android’s Font Renderer
Any developer with a few years of experience writing client-side applications is acutely aware of how complicated text rendering can be.

I then realized that text gets even more complicated when you’re trying to use a GPU to draw it on screen. In this post, read about an approach on how a complete GPU-based text rendering system can be implemented. This article also describes a few optimizations that are easy to implement.

In this lesson we’re going to learn about the component used to house our dependency declarations, modules. Here we’ll learn about what koin modules are, followed by creating our first module which will be used to define the injectable dependencies throughout our application.
Caster.io: Loading our Dependencies
Our dependency graph can be ‘drawn’ by starting koin with our specified modules. We can also load modules at a later point in our application if desired – and in this lesson we’ll cover how these topics work and are used.

BubbleGum was designed to help developers quickly apply gradients into different UI elements of an Android App. The overhead and performance impact is minimal, as BubbleGum is based on Android drawables. Features include applying gradients to a view with an animation effect or transition between two gradients, and creating an animated view with a set of gradients that interchange at the specified amount of time.
