Reducing a total amount of memory usage of an edge device by swapping application logics

A computer program product, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform operations for:

• grouping a first application and a swap application that share an application framework, wherein one of the first application and the swap application executes in the application framework at a time;
• executing the first application in a foreground on the application framework, wherein the first application has a shown status and is attached to the application framework;
• and
• in response to receiving a request to execute the swap application,
• determining that the first application and the swap application use a same screen type and a same non-shareable resource;
• storing an application logic of the first application in a suspended application logic pool, wherein the first application changes from the shown status to a hidden-suspended status and is detached from the application framework;
• and
• executing the swap application in the foreground on the application framework, wherein the swap application has the shown status and is attached to the application framework.

A computer system, comprising:

• one or more processors, one or more computer-readable memories and one or more computer-readable, tangible storage devices;
• and
• program instructions, stored on at least one of the one or more computer-readable, tangible storage devices for execution by at least one of the one or more processors via at least one of the one or more computer-readable memories, to perform operations comprising:
• grouping a first application and a swap application that share an application framework, wherein one of the first application and the swap application executes in the application framework at a time;
• executing the first application in a foreground on the application framework, wherein the first application has a shown status and is attached to the application framework;
• and
• in response to receiving a request to execute swap application,
• determining that the first application and the swap application use a same screen type and a same non-shareable resource;
• storing an application logic of the first application in a suspended application logic pool, wherein the first application changes from the shown status to a hidden-suspended status and is detached from the application framework;
• and
• executing the swap application in the foreground on the application framework, wherein the swap application has the shown status and is attached to the application framework.
