|Android Studio 2 Beta Is Usable|

Android Studio 2 is now available in beta and this change in status does correspond to an increased usability. It is worth getting to know the new IDE because, even with its faults, it speeds development a lot.
The major feature of Android Studio 2 isn't really part of the IDE. The emulator is now much faster and comes with more features. Put simply, it is usable. No longer do you have to acquire and install a third party emulator to make development easier. The new emulator really does satisfy the need.
There are some drawbacks, however. The first is that you need an Intel or AMD CPU that supports virtualization - Intel Atom CPUs don't. You also need to install the Intel HAXM accelerator. This isn't a huge problem, but it is incompatible with HyperV so if you are using Windows you have to disable HyperV to use the faster emulator.
There is still the irritation that HAXM's memory default is lower than the memory allocation on most of the Android images you can run without custom configuration. The workaround is to up the HAXM memory to 1GByte unless you are very short of memory.
There is also the small matter that you can only make use of Intel Android images.
None of these is a big problem and overall this is now the emulator that we should have had ages ago.
The emulator supports multiple cores for both speed and for testing out app features. The user interface makes it very easy to emulate the behavior of a real device. New in the beta are the improved rotation controls and the multi-touch emulation. All this, coupled with the improvements in the ADB, means that often the emulator seems as responsive as a real device.
The second big improvement is instant run. This attempts to intelligently work out what has changed and downloads to the running app as little as possible.
There are three possibilities:
Notice that in all cases only the parts of the app that have changed are downloaded.
With the new emulator and instant run the time to cycle through an edit, debug, edit cycle is much reduced and this should mean both faster development and fewer residual bugs.
Also new in the beta is code generation for App Indexing and validation. App indexing is relatively new but it is likely to become an essential feature in the future so anything that makes it easier is a good idea.
The bottom line is that Android Studio 2 offers sufficient advantages to start using it now before the release. Of course the usual beta warnings apply and you should install it alongside the latest release version. All you have to do is download the zip file, unzip it anywhere convenient and run studio64.exe. After this you will have to put up with a few rounds of updates. Eventually this are complete and you can start using Android Studio 2. Any new projects that you create will make use of the new instant run without you doing anything. Any projects you import will have to change the line in the build.gradle project file to read
Using the new emulator is just a matter of creating an AVD that uses Android 6.0 x86 image and API 23. You can also select the advanced settings to select the number of cores you want to use.
Of course there are still some Android programmers angry that Android Studio still doesn't provide support for native code (NDK) development. It is also ironic that Microsoft's Visual Studio seems to do a better job in this respect. The problem is that switching to Visual Studio might be attractive in the short term but the gamble is how long Microsoft will think it worth supporting Android NDK development.
For the moment the only reasonable thing to do is to stay with Eclipse and the ADT. However if you don't need native code development the new Android Studio is well worth switching to.
