Google first introduced Android Studio for developers to build Android apps back in May, 2013. Now, the freely available integrated development environment reaches version 2.0 in a preview form.
Google made Android Studio 2.0 available on Monday during its Android Developer Summit event. The IDE is based on IntelliJ for efficient programming and debugging and works on Microsoft Windows, Mac OS X and Linux machines.
This first preview version is aimed at performance increases: Google says Android Studio's new Instant Run feature lets a developer make code changes and see them in the built-in emulator or on a connected device much faster.
Developers will have to enable Instant Run to use the function; the setting is found under the Build, Execution, Deployment setting in the app's preferences. It is also limited to Android apps using API level 14 or higher.
Note too that some code changes aren't yet supported by Instant Run. Namely, you can only use it when changing an instance method or static method implementation, or when adding or removing a class.
Despite the current limitations, Instant Run can populate builds up to 50 times faster than before and the overal IDE is about five times quicker when writing apps for Android 6.0 devices, Google tells The Next Web.
Also in the Android Studio 2.0 preview is a GPU Profiler function that shows details about the GL State of an app's code.
This experimental feature is an optional add on that first needs to be downloaded and installed through the SDK tools of Android Studio 2.0
