Drag and drop for touchscreen devices

A method comprising:

• receiving, by a user interface manager application executing on a processor with system-level privileges, a request to add a first item of a source application to a drag session associated with at least a second item of the source application, the source application executing on the processor;
• determining a first identifier of the first item;
• and
• associating the first identifier of the first item to the drag session responsive to receiving the request, wherein associating the first identifier of the first item to the drag session comprises:
• adding the first identifier of the first item to a data structure that comprises at least a second identifier of the at least the second item associated with the drag session;
• and
• when at least one of first or second items is requested by a destination application executing on the processor, providing a link to a file provider that is executing on the processor in a sandbox environment separate from the user interface manager application and the source and destination applications executing on the processor, the file provider fulfilling a data transfer corresponding to the at least one of the first or second items.

A computer program product comprising code stored in a non-transitory computer-readable storage medium, the code comprising:

• code to receive, by a manager application executing on a processor in conjunction with a source application and a destination application executing on the processor, a request for a representation of an item from the destination application, the manager application comprising a user interface process with system-level privileges;
• code to send the request for the representation of the item to the source application;
• code to receive, by the manager application, a link to a file provider that is executing on the processor in a sandbox environment separate from the manager application and the source and destination applications, the file provider fulfilling a data transfer of the representation of the item;
• and
• code to send, by the manager application, the link to the file provider to the destination application, wherein the manager application is separate from the source application and the destination application.
