Abstract: The number of Android applications is increasing rapidly. However, some Android applications running on the smartphones are limited by the conditions of the smartphones themselves, such as insufficiency of CPU resources or malfunctioned sensors. They also face the problem of remote control due to their richer application scenarios.  Computation offloading is proposed to solve this problem by transferring the complex computation tasks contained in the app to a server to execute and then returning the result back to the app. But there still remain problems such as complicated client-server connecting. This paper presents MultiOffloading, an Android application offloading platform which supports computation offloading, sensing offloading and touch offloading at the same time. The smartphones which have already installed MultiOffloading can find and connect each other to form a P2P network. The applications on the platform can borrow computation, sensor and screen resources from other devices. This paper extends existing computation offloading and sensing offloading approaches and enhances them with the support for touch offloading via program instrumentation. At last it gives a demo to confirm the feasibility of the offloading platform design and chooses two Apps to display the offloading effect.
