p MOUNTAIN VIEW, Calif.—Starting with Android 4.4, Google began to support a "low RAM" flag for devices with 512MB of memory.

The low-RAM configuration changes how the OS and supported apps work, with the goal of reducing resource usage.

That initiative was called "Project Svelte," and it was aimed at low-end phones for emerging markets.

Today at Google I/O, the company announced a new initiative to continue and extend these efforts.

"Android Go" will be a part of Android O, and it will also include optimized versions of apps and the Google Play Store to reduce resource and data usage.

Think of Android Go as a modified version of Android O.
