By now you've probably heard about ART and how it will improve the speed and performance of Android, but how does it actually perform today? The new Android Runtime promises to cut out a substantial amount of overhead by losing the baggage imposed by Dalvik, which sounds great, but it's still far from mature and hasn't been seriously optimized yet. I took to running a battery of benchmarks against it to find out if the new runtime could really deliver on these high expectations.
It's fair to say that Android went through some chaotic years in the beginning. The pace of development was frantic as the operating system grew at an unprecedented rate. An as-yet undetermined future led to decisions that were made to conform to existing hardware and architectures, the available development tools, and the basic need to ship working code on tight deadlines. Now that the OS has matured, the Android team has been giving more attention to some of the components that haven't aged quite as well.
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.
This week, we saw a new kid among Android decompilers hit the street - JEB. JEB is a full featured, commercial dalvik decompiler aimed at security researchers and reverse engineers. Although many other decompilers exist, such as DED, Androguard, baksmali, dex2jar, undx, etc and most of them are free and work quite well, JEB comes with features not seen in most free tools:
- Easy to use UI
- Direct dalvik to java decompilation
- Easy on the eyes bytecode
- Easy cross referencing of items
- Easy renaming of items
The downside is mainly the price, weighing in at a hefty $1000.
Myriad is continuing their quest to make Android apps run on just about everything with the release of Alien Dalvik 2.0. The latest operation system in their crosshairs is none other than iOS -- specifically the iPad branch of iOS. That's right, Android apps on an iPad.
I can sense your skepticism over the internet (it's a new WordPress plugin) so perhaps some background info will make this a little more believable: Myriad is a founding member of the Open Handset Alliance, a Google-assembled group of companies that support Android.
Some combinations are as natural as peanut butter and jelly - Avatar & 3D, Apple & dictatorship, and Conan O'Brien & late-night comedy, to name a few. But are Android apps and the BlackBerry PlayBook also such a sweet match? If you ask RIM, the answer is a firm, definitive "yes."
The BlackBerry maker just confirmed the age-old rumors - it's announced that the upcoming QNX-based PlayBook tablet will support Android apps.
About 2 weeks ago, BGR broke the rumor of RIM's upcoming tablet, the BlackBerry PlayBook, possibly being capable of running Android apps sometime after launch, which the latest rumors put at the end of March/beginning of April with a price sticker of $499.99. The company was seriously looking into this possibility and was trying to decide whether using the Dalvik virtual machine (the same one Android uses to run its apps) was a viable way to move forward.
Zurich-based mobile software developer Myriad Group has announced the launch of "Alien Dalvik", an emulator which will enable unmodified Android apps to run on devices not using the Android OS.
App stores will be able to add Android apps to their repositories and they will be able to use Alien Dalvik to simply repackage the Android Package (APK) files for any device. Myriad promises that the repackaged Android app will run seamlessly and can be installed and uninstalled like any other native app.
As if Oracle's, Microsoft's, and Apple's   suits weren't giving Android enough headache, today, Gemalto, an Amsterdam-based digital security company, added some fuel to the flames by filing a patent infringement suit against Google and its partners HTC, Samsung, and Motorola. The suit claimed that Android and the Dalvik operating environment incorporated Gemalto's patented Java Card technology without the company's permission.
The Wall Street Journal explained in more detail:
Them’s Fightin’ Words
As you may have heard, Oracle (who now own Sun and the Java programming language) filed a patent infringement suit against Google related to the use of Java on the Android platform (particularly in the Dalvik VM, details on TechCrunch if you’re interested). Google has responded to Oracle’s suit, and they are ready to make a stand:
