AppStreamer software was developed to stream data and code resources to an app from a cloud server when necessary, allowing an app to use only the space it needs on a phone at any given time. Application components such as heavy video, graphics, or code paths stream instantly despite the errors and slowdowns that are possible on a cellular network. The software also cuts down storage requirements by at least 85% for popular gaming apps on an Android.

AppStreamer seamlessly shuffles data between an app and a cloud server without stalling the game. Since it works for storage-hungry gaming apps, it could work for other apps that usually take up far less space. The software also allows the app itself to download faster to a phone.

The middleware, located between the apps on a device and the operating system, automatically predicts when to fetch data from a cloud server. AppStreamer could help phones better accommodate 5G connectivity — high-speed wireless cellular networks that would allow devices to download movies in seconds and handle other data-heavy tasks much faster than the 4G networks currently available to most phones. Using AppStreamer on a 5G network would mean that an app downloads instantly, runs faster, and takes up minimal space on a phone.

The researchers also designed AppStreamer to use edge computing, which stores and sends data from edge servers. These servers, located in spots such as cell-phone towers, are closer to a device compared to the cloud. The shorter distance reduces data download time.
