Demonstrates how to identify and avoid line-length issues with TextView. The measure, or characters per line, of a block of text plays a key role in how comfortable it is to read (sometimes referred to as readability). A widely accepted optimal range for a text block's measure is between 45 and 75 characters. This code demonstrates two phases of…

Adding support for ".res-auto" in ContentProvider authorities in AndroidManifest.xml. This replaces ".res-auto" with the current package name, making it possible to install multiple build variants on the same devices without getting [INSTALL_FAILED_CONFLICTING_PROVIDER]

Gradle & Android: Disable/Enable preDexing
// add this to the general build.gradle, not in the subproject's build.gradle
// improved version of Xavier's tip http://tools.android.com/tech-docs/new-build-system/tips#TOC-Improving-Build-Server-performance.
// usage example default, preDex will be enabled: gradle clean build
// usage example disabling preDex: gradle clean build -PpreDexEnable=false
// preDexEnable parameter's value can be set as property of Continuous Integration build config
// this is the main difference from Xavier's workaround where he doing only hasProperty check

This gist demonstrates how to create an animated pause/resume media playback button for Android. It uses animated vector drawables and state transitions to orchestrate the effect. Some background: https://plus.google.com/u/0/+MoritzPost/posts/3EFF8uC7jXv

A composable pattern for pure state machines with effects (draft v3)

A composable pattern for pure state machines with effects

State machines are everywhere in interactive systems, but they're rarely defined clearly and explicitly. Given some big blob of code including implicit state machines, which transitions are possible and under what conditions? What effects take place on what transitions?

There are existing design patterns for state machines, but all the patterns I've seen complect side effects with the structure of the state machine itself. Instances of these patterns are difficult to test without mocking, and they end up with more dependencies. Worse, the classic patterns compose poorly: hierarchical state machines are typically not straightforward extensions. The functional programming world has solutions, but they don't transpose neatly enough to be broadly usable in mainstream languages.

Here I present a composable pattern for pure state machiness with effects,
