Abstract

The subject matter of this specification can be embodied in, among other things, a method that includes specifying, with uniform resource identifiers (URIs), substantially all data accessible by applications on a device. The method also includes receiving at a universal interface a request from an application on the device for data that is specified by a URI associated with the request. Substantially all requests for data from applications on the device are received at the universal interface. The method also includes determining, based on the URI associated with the request, a content provider responsible for managing the requested data, and outputting the requested data to the application using the determined content provider to obtain the requested data based on the URI associated with the request.

Claims

1. A method performed by a computing device having a memory and processor configured to execute multiple applications, the method comprising:

maintaining, in the memory of the computing device;

multiple sets of distinct content items, wherein each set includes one or more content items having a different content type,

multiple content providers, each content provider associated with a different content type,

multiple applications configured to submit requests for one or more content items;

a data structure containing multiple Uniform Resource Indicators (URI), a URI including an indication of a content type and a reference to a content item, and

a universal interface configured to;

receive a request from any of the multiple applications for a content item stored in the memory of the computing device, the request including an entire URI or a truncated URI, and

alone or in conjunction with an activity manager, using the data structure and the entire URI or the truncated URI to determine which content provider separate from the requesting application is to respond to the request and identify one or more content items responsive to the request;

receiving, by the universal interface, a request for a particular content item from a first application of the multiple applications, the request including a truncated URI;

alone or in conjunction with the activity manager, using, by the universal interface, the data structure and the entire URI or the truncated URI to

determine a particular content provider that is separate from the first application to respond to the request;

using, by the particular content provider, the entire URI or the truncated URI to obtain the content item responsive to the request that is stored in the data structure;

transmitting, with the particular content provider and to the universal interface, the content item that is responsive to the request; and

transmitting, with the universal interface, the content item to the at least one requesting application.

2. The method of claim 1, wherein using the data structure and the entire URI or the truncated URI to determine the particulate content provider is to respond to the request comprises parsing the URI to identify an authority name used to specify the content provider.

3. The method of claim 1, wherein the content provider obtains the requested content item using the URI to identify the requested content item in a database.

4. The method of claim 3, wherein a first portion of the URI identifies the content provider and a second portion identifies the requested content item in the database.

5. The method of claim 3, wherein each record in the database is specified with at least one unique URI.

6. The method of claim 3, wherein a group of records is specified using the truncated portion of the URI.

7. The method of claim 1, wherein the content provider obtains the requested content item using the URI to identify the requested content item in a subscriber identity module (SIM) card or a flash memory card.

8. The method of claim 1, wherein using the entire URI or the truncated URI to obtain the content item responsive to the request comprises generating the requested content item by the content provider using information included in the URI.

9. The method of claim 1, further comprising initiating execution of the content provider if the content provider is not executing when the request is received.

10. The method of claim 1, further comprising stopping execution of the content provider after the content provider returns the requested content item.

11. The method of claim 1, further comprising checking a scope of authorization associated with the at least one requesting application before the content provider obtains the requested content item, wherein the authorization comprises a permission setting that specifies whether the at least one requesting application is permitted to receive content items from or transmit content items to the content provider.

12. The method of claim 1, further comprising registering one or more scopes of authorization to associate with the at least one requesting application if the at least one requesting application is digitally signed by a third-party.

13. The method of claim 1, further comprising registering content providers with particular URIs to identify which content providers are responsible for managing content items associated with the particular URIs.

14. The method of claim 1, further comprising receiving a request from the at least one requesting application to store a generated content item, wherein the request comprises the generated content item and a second URI that specifies a logical location to store the generated content item.

15. The method of claim 14, further comprising determining that the content provider is responsible for managing the generated content item based on the second URI and storing the content item based on a location specified by the second URI.

16. The method of claim 1, wherein the content provider services requests for content items from different applications.

17. The method of claim 1, wherein requests for content items from the multiple applications are received at the universal interface.

18. The method of claim 1, wherein content items are provided to the requesting application from content providers through the universal interface.

19. A computer program product tangibly embodied in a non-transitory computer readable storage medium of a computing device, the computer program product including instructions that, when executed by one or more processors, perform operations comprising:

maintaining;

multiple sets of distinct content items, wherein each set includes one or more content items having a different content type,

multiple content providers, each content provider associated with a different content type,

multiple applications configured to submit requests for one or more content items;

a data structure containing multiple Uniform Resource Indicators (URI), a URI including an indication of a content type and a reference to a content item, and

a universal interface configured to;

receive a request from any of the multiple applications for a content item stored in memory of the computing device, the request including an entire URI or a truncated URI, and

alone or in conjunction with an activity manager, using the data structure and the entire URI or the truncated URI to determine which content provider separate from the requesting application is to respond to the request and identify one or more content items responsive to the request;

receiving, by the universal interface, a request for a particular content item from a first application of the multiple applications, the request including a truncated URI;

alone or in conjunction with the activity manager, using, by the universal interface, the data structure and the entire URI or the truncated URI to

determine a particular content provider that is separate from the first application to respond to the request;

using, by the particular content provider, the entire URI or the truncated URI to obtain the content item responsive to the request that is stored in the data structure;

transmitting, with the particular content provider and to the universal interface, the content item that is responsive to the request; and

transmitting, with the universal interface, the content item to the at least one requesting application.

20. A system comprising:

one or more computer processors; and

one or more non-transitory computer readable devices that includes instructions that, when executed by the one or more computer processors, causes the processors to perform operations, the operations comprising;

maintaining;

multiple sets of distinct content items, wherein each set includes one or more content items having a different content type,

multiple content providers, each content provider associated with a different content type,

multiple applications configured to submit requests for one or more content items;

a data structure containing multiple Uniform Resource Indicators (URI), a URI including an indication of a content type and a reference to a content item, and

a universal interface configured to;

receive a request from any of the multiple applications for a content item stored in the one or more non-transitory computer readable devices, the request including an entire URI or a truncated URI, and

alone or in conjunction with an activity manager, using the data structure and the entire URI or the truncated URI to determine which content provider separate from the requesting application is to respond to the request and identify one or more content items responsive to the request;

receiving, by the universal interface, a request for a particular content item from a first application of the multiple applications, the request including a truncated URI;

alone or in conjunction with the activity manager, using, by the universal interface, the data structure and the entire URI or the truncated URI to

determine a particular content provider that is separate from the first application to respond to the request;

using, by the particular content provider, the entire URI or the truncated URI to obtain the content item responsive to the request that is stored in the data structure;

transmitting, with the particular content provider and to the universal interface, the content item that is responsive to the request; and

transmitting, with the universal interface, the content item to the at least one requesting application.
