Abstract

The subject technology provides for detecting a drag gesture selecting an item in a first application. The subject technology detects a touch release at an end of the drag gesture for dropping the item in a second application. The subject technology sends in response to the detected touch release, a message to the second application, the message including information for a plurality of representations of the item. The subject technology receives, from the second application, a request for a representation of the item from among the plurality of representations. The subject technology sends, to the first application, the request for the representation of the item. Further, the subject technology initiates a data transfer of the representation of the item from the first application to the second application.

Claims

1. A method comprising:

detecting a drag gesture selecting an item in a first application;

detecting a touch release at an end of the drag gesture for dropping the item in a second application;

sending, in response to the detected touch release, a message to the second application, the message including information for a plurality of representations of the item;

receiving, from the second application, a request for a representation of the item from among the plurality of representations;

sending, to the first application, the request for the representation of the item; and

initiating a data transfer of the representation of the item from the first application to the second application.

2. The method of claim 1, wherein each representation from the plurality of representations is associated with a uniform type identifier (UTI).

3. The method of claim 1, wherein the request for the representation of the item indicates a particular representation with a highest degree of fidelity among the plurality of representations.

4. The method of claim 1, wherein initiating the data transfer of the representation of the item from the first application to the second application comprises:

providing, to the second application, a connection to the first application for performing the data transfer of the representation of the item.

5. The method of claim 1, wherein initiating the data transfer of the representation of the item from the first application to the second application further comprises:

determining that the second application is not currently executing;

launching the second application; and

providing, to the second application, a connection to the first application for completing the data transfer.

6. The method of claim 1 further comprising:

determining, using a data access policy, whether the second application has access to data corresponding to the item being dropped, wherein the data access policy is based at least in part on whether the first application and second application are both managed applications; and

denying completion of a drag and drop event in response to determining that the second application does not have access to the data corresponding to the item being dropped.

7. The method of claim 6, wherein determining, using the data access policy, whether the second application has access to data corresponding to the item being dropped is further based on determining whether the item being dropped is associated with a same type of account that is associated with the second application, or whether the item being dropped was dragged from a view associated with the same type of account that is associated with the second application.

8. The method of claim 6, further comprising:

allowing completion of the drag and drop event in response to determining that the second application has access to the data corresponding to the item being dropped.

9. A device comprising;

at least one memory; and

at least one processor configured to;

detect a drag gesture selecting an item in a first application;

detect a touch release at an end of the drag gesture for dropping the item in a second application;

send, in response to the detected touch release, a message to the second application, the message including information for a plurality of representations of the item;

receive, from the second application, a request for a representation of the item from among the plurality of representations;

send, to the first application, the request for the representation of the item; and

initiate a data transfer of the representation of the item from the first application to the second application.

10. The device of claim 9, wherein each representation from the plurality of representations is associated with a uniform type identifier (UTI).

11. The device of claim 9, wherein the request for the representation of the item indicates a particular representation with a highest degree of fidelity among the plurality of representations.

12. The device of claim 9, wherein the at least one processor is further configured to:

provide, to the second application, a connection to the first application for performing the data transfer of the representation of the item.

13. The device of claim 9, wherein the at least one processor is further configured to:

determine that the second application is not currently executing;

launch the second application; and

provide, to the second application, a connection to the first application for completing the data transfer.

14. The device of claim 9, wherein the at least one processor is further configured to:

determine, using a data access policy, whether the second application has access to data corresponding to the item being dropped, wherein the data access policy is based on whether the first application and second application are both managed applications; and

deny completion of a drag and drop event in response to determining that the second application does not have access to the data corresponding to the item being dropped.

15. The device of claim 14, wherein to determine, using the data access policy, whether the second application has access to data corresponding to the item being dropped is further based on determining whether the item being dropped is associated with a same type of account that is associated with the second application, or whether the item being dropped was dragged from a view associated with the same type of account as is associated with the second application.

16. The device of claim 14, wherein the at least one processor is further configured to:

allow completion of the drag and drop event in response to determining that the second application has access to the data corresponding to the item being dropped.

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

code to detect a drag gesture selecting an item in a first application;

code to detect a touch release at an end of the drag gesture for dropping the item in a second application;

code to send, in response to the detected touch release, a message to the second application, the message including information for a plurality of representations of the item;

code to receive, from the second application, a request for a representation of the item from among the plurality of representations;

code to send, to the first application, the request for the representation of the item; and

code to initiate a data transfer of the representation of the item from the first application to the second application.

18. The computer program product of claim 17, wherein the code further comprises:

code to determine, using a data access policy, whether the second application has access to data corresponding to the dropped item; and

code to deny completion of a drag and drop event in response to determining that the second application does not have access to the data corresponding to the dropped item.

19. The computer program product of claim 17, wherein the code further comprises:

code to determine, using a data access policy, whether the second application has access to data corresponding to the item being dropped, wherein the data access policy is based at least in part on whether the first application and second application are both managed applications;

code to deny completion of a drag and drop event in response to determining that the second application does not have access to the data corresponding to the item being dropped; and

code to allow completion of the drag and drop event in response to determining that the second application has access to the data corresponding to the item being dropped.

20. The computer program product of claim 19, wherein the code to determine, using the data access policy, whether the second application has access to data corresponding to the item being dropped is further based on determining whether the item being dropped is associated with a same type of account that is associated with the second application, or whether the item being dropped was dragged from a view associated with the same type of account that is associated with the second application.
