Google is previewing a big update to Android Studio, bumping it up to version 2.0 with some big speed improvements. The key feature of this update is its speed, and how much faster developers will be able to build and deploy their apps. A new instant run feature allows you to quickly see the changes running either on your device or an emulator.
In addition, it has added a GPU Profiler, which is in early preview. With this, you'll be able to see details about the GL State and Commands, and record the entire sessions and walk through the GL Framebuffer and Texures as your app is running. These changes are just the beginning, and over the course of the next few weeks Google will be adding more.
