Android Support Library v23.2 Adds Auto-Switching Day/Night Theme, Support For Vector Drawables, And Much More

A fresh version of the Android Support Library is now available to developers. This may be one of the biggest updates in quite a while, as some of the changes demand a few significant internal changes. On the plus side, there aren't very many changes that should break existing code, and most of the new features will make it worth the trouble. Here's a quick introduction to some of the new changes.

Vector Drawables and Animated Vector Drawables

Full vector support was first introduced in Android 5.0 Lollipop, allowing developers to distribute apks with easily resizable vector drawings in place of multiple images at various sizes.

HTC Posts One M9 Android 6.0 Kernel Files, Includes Variants Such As The Dev Edition Unlocked And EU Model

When a manufacturer open sources the code that makes their device work, it's an occasion worth noting. This is one of the strengths of Android, the availability of files that enable developers and tinkerers to create software that can replace the firmware that our devices ship with. It's one of Android's differentiating factors compared to iOS and Windows Phone.

JetBrains Releases v1.0 Of Kotlin, A Smart JVM-Compatible Language That Can Be Used To Write Android Apps

Kotlin has been emerging as a programming language to keep a close eye on. It started as an internal project at JetBrains back in 2011 and was released early the next year. Taking inspiration from both classic C-based languages and a number of modern alternatives like Scala, Kotlin is branded as a "pragmatic" language and modeled to encourage smarter coding and easier readability. JetBrains has been tiptoeing up to an official v1.0 release for a few months, and today, it's finally here.

While it's still a fledgling language, Kotlin has earned some enthusiastic supporters among the Android development community, even a few Googlers have discussed using it in projects.

Android Studio 2.0 Hits Beta 2 With Faster Build And Deploy Times, Instant Run, Fast New Emulator, GPU Profiler, The Latest IntelliJ 15 Improvements, And Much More

The Android Studio team has been kicking out preview builds at a fevered pace since the first 2.0 preview hit the scene near the end of November, and it's finally paying off as the first real Beta is now rolling out. (The first beta has an issue, so this is actually labeled Beta 2). The jump from v1.5 to v2.0 is enough to suggest that this could be the most ambitious update to the IDE since it was launched, but the feature list confirms it. We've already covered some of the biggest features: instant run, GPU profiling, and a massively faster and more functional emulator.

CyanogenMod's Upcoming Protected App Interface Is Super Slick, And It Supports Fingerprint Authentication

Some of the most interesting additions to Android often come from unofficial sources. Maligned though they may be, Google has incorporated many features previously only found in manufacturer skins into AOSP, and custom ROM developers add new features more or less as they feel like it, some of which are quite useful. For example, the CyanogenMod development team is working on a new integrated system for handling "locked" apps, applications that can't be accessed by the user without a password or other validation mechanism.

Google Will Replace Oracle's Java APIs With OpenJDK In The Next Version Of Android

Android's rapid rise to the top of the mobile market was accompanied by a number of legal battles, and perhaps none of them was so central and so contentious as Oracle versus Google. The fight over the legality of patents and copyrights in some of the portions of Android that used allegedly proprietary Oracle-owned Java software has been raging since 2010, eventually being considered for review by the US Supreme Court before being bounced back to the lower appeals court. The fight was a constant, and sometimes dramatic, part of legal software news at one point.

Apparently Google is as tired of dealing with the legal headache as we are of writing about it, because the company has confirmed that Android will do away with the remaining Java APIs starting with Android N, which will probably be released sometime in 2016.

[Freebie Alert] Hurry: Packt Is Giving Away The Android NDK Game Development Cookbook For Free

If you're reading this, chances are you know more about the topic than I do. I am not a developer, and although I have always wanted to dabble a bit with app and game development (at least when it comes to the basics), I can almost never find a single free minute in the day for me to do that. But I'll do my best to explain what this book and deal are all about.
