If you're a developer who likes to tinker with Android apps and see what makes them tick, you've probably heard of Apktool. And if you've tried to do that with some of Google's recent apps, or any apps that have been updated with Lollipop support, you've probably discovered that the Java applet doesn't always work for them. Developer Connor Tumbleson just posted the third release candidate for Apktool, which should fix most of those problems.
If you're in the modding and theming community, your work is about to get a bit faster, because Smali v2.0 is now in beta and firing on all cylinders. The new version brings multithreaded processing and a few tweaks to the language that should result in cleaner-looking code.
Apktool is a Windows/Mac/Linux utility for reverse engineering Android apps. It allows you to decode an app, change something, rebuild it, and pray it still runs. You're going to need something like this if you're into theming apps, hacking a feature onto someone else's app, finding security holes, or just want to hunt for info.
Apktool has been freshly updated to version 1.5.1, with the new headline feature being "Android 4.2 support." Here's the full changelog.
