Systems and methods for in-application dynamic content loading
In some aspects, the disclosure is directed to methods and systems for in-application dynamic content loading via a hybrid process, including both local and remote content items, via a content handler intercepting requests in a predetermined uniform resource locator (URL) scheme and redirecting the requests to local storage or a remote content provider, transparently to a browser application or webview of the application, and avoiding restrictions imposed by an operating system of the device. Content may be dynamically updated on the content provider server by developers, and dynamically loaded during execution of the application on client devices, without requiring updates to be provided to an application store or publisher server.
1. A method for in-application dynamic content loading, comprising:
executing, by a computing device, an application comprising a browser application and a content handler;
intercepting, by the content handler, a first request from the browser application to retrieve an item of content via a uniform resource locator (URL) having a domain portion and a directory portion, responsive to the first request having a first predetermined URL scheme;
responsive to determining that the item of content does not exist at a particular location in memory of the computing device, replacing, by the content handler, a first protocol portion of the first predetermined URL scheme in the first request from the browser application with a second protocol portion of a second predetermined URL scheme to generate a modified first request that comprises the domain portion of the first request, the first protocol portion of the first predetermined URL scheme used by the content handler to intercept the first request;
transmitting, by the computing device, a second request to a remote device corresponding to the modified first request; and
receiving, by the computing device from the remote device, the item of content for the browser application.
2. The method of claim 1 , further comprising:
translating, by the content handler, binary data of the received item of content into a data string;
replacing, by the content handler, one or more references to the second predetermined URL scheme within the data string with references to the first predetermined URL scheme to generate a modified data string;
translating, by the content handler, the modified data string into modified binary data; and
providing, by the content handler, the modified binary data to the browser application.
3. The method of claim 2 , wherein replacing the one or more references to the second predetermined URL scheme with the data string further comprises replacing a plurality of references to the second predetermined URL scheme with references to the first predetermined URL scheme.
4. The method of claim 2 , wherein the item of content comprises executable code.
5. The method of claim 2 , wherein providing the modified binary data to the browser application further comprises generating a response to the first request comprising the modified binary data.
6. The method of claim 1 , further comprising determining, by the content handler, that the item of content does not exist at a location in memory of the computing device corresponding to the directory portion of the URL.
7. The method of claim 6 , wherein determining that the item of content does not exist at the location in memory of the computing device further comprises determining that the item of content is not identified in a manifest of the application.
8. The method of claim 7 , further comprising extracting data from a header from the received item of content, and adding the data to the manifest of the application.
9. The method of claim 1 , wherein the first predetermined URL scheme is not supported by the browser application or an operating system of the computing device.
10. The method of claim 1 , wherein an operating system of the computing device prevents transmission of requests from the application having the second predetermined URL scheme, responsive to transmission of the first request having the first predetermined URL scheme.
11. The method of claim 6 , wherein determining that the item of content does not exist at the location in memory of the computing device further comprises identifying a type of the item of content; and determining that a manifest of the application does not identify the type of the item of content.
12. A system for in-application dynamic content loading, comprising:
a computing device comprising a processor, a network interface, and a memory device, the processor executing an application comprising a browser application and a content handler;
wherein the content handler is configured to:
intercept a first request from the browser application to retrieve an item of content via a uniform resource locator (URL) having a domain portion and a directory portion, responsive to the first request having a first predetermined URL scheme, and
responsive to determining that the item of content does not exist at a particular location in memory of the computing device replace a first protocol portion of the first predetermined URL scheme in the first request from the browser application with a second protocol portion of a second predetermined URL scheme to generate a modified first request that comprises the domain portion of the first request, the first protocol portion of the first predetermined URL scheme used by the content handler to intercept the first request; and
wherein the network interface is configured to:
transmit a second request to a remote device corresponding to the modified first request, and
receive, from the remote device, the item of content for the browser application.
13. The system of claim 12 , wherein the content handler is further configured to:
translate binary data of the received item of content into a data string;
replace one or more references to the second predetermined URL scheme within the data string with references to the first predetermined URL scheme to generate a modified data string;
translate the modified data string into modified binary data; and
provide the modified binary data to the browser application.
14. The system of claim 13 , wherein the content handler is further configured to replace a plurality of references to the second predetermined URL scheme with references to the first predetermined URL scheme.
15. The system of claim 13 , wherein the content handler is further configured to generate a response to the first request comprising the modified binary data.
16. The system of claim 12 , wherein the content handler is configured to determine that the item of content does not exist at a location in memory of the computing device corresponding to the directory portion of the URL.
17. The system of claim 16 , wherein the content handler is further configured to determine that the item of content is not identified in a manifest of the application.
18. The system of claim 12 , wherein the first predetermined URL scheme is not supported by the browser application or an operating system of the computing device.
19. The system of claim 12 , wherein an operating system of the computing device prevents transmission of requests from the application having the second predetermined URL scheme, responsive to transmission of the first request having the first predetermined URL scheme.
20. The system of claim 12 , wherein the content handler is further configured to:
identify a type of the item of content; and
determine that a manifest of the application does not identify the type of the item of content.
