Right now, Google's instant Android apps don't quite live up to their billing. Google has to load support for every possible device, which can slow down access to the app and chew up valuable space. That shouldn't be an issue going forward. Google has updated its instant app programming kit to let developers give you configurations that only target specific device profiles based on the display, chip architecture and language. If you're using a low-resolution screen, an ARM processor and Chinese, for example, you won't get the data needed for a sharper display, Intel chips and other languages. Google reckons that this saves an average of 10 percent space, which should translate to faster-loading apps.
