"Working As Intended" - An Exploration into Android's Accessibility Lag
Android's Accessibility feature is known to cause UI lag. Is it a bug, or is it a feature? Why does it occur? We at XDA investigate the root cause.
The beauty of Android lies in the many different ways that third-party applications can interact with the system. Password manager apps such as LastPass provide the ability to automatically feed relevant username/password data to almost any login screen. Text Aide allows you to significantly shorten your time texting your friends by allowing you to create text expansion macros. Native Clipboard decreases the hassle involved with frequently switching between apps to copy large amounts of text by allowing you to double-tap any input field to bring up a clipboard. Who can forget Greenify, perhaps the #1 most recommended app by enthusiasts, which keeps rogue background apps in check and can thus enhances battery life? Finally, albeit less familiar with most users, there's AutoInput - a Tasker plug-in designed to automate screen taps, text input, swipe gestures, and much more. These apps all serve vastly different use cases, but each of these apps rely on a very misunderstood part of core Android functionality: Accessibility.
