Application dehydration and rehydration during application-to-application calls

摘要

Methods, systems, and computer program products are provided that enable a first application (i.e., a caller application) to call a second application (i.e., a callee application) to perform a function in a manner such that the first application may be dehydrated during the call. Dehydrating includes terminating execution of an instance of the first application, and freeing memory space in a memory of a mobile device that stored the instance of the first application. In such case, the second application may be active while the first application is no longer present in memory. The second application is enabled to respond to the call, causing the first application to be rehydrated. The first application continues execution at a location where the first application was dehydrated, and receives the response to the call.
