Seamless editing and saving of online content items using applications

An electronic device comprising:

• a data communication interface operable to communicate with an online content management service system;
• a user interface including a display and a user input device;
• and
• a processing unit coupled to the data communication interface and the user interface, the processing unit configured to:
• provide by a client application configured to interface with the online content management service system, authorization information to the online content management service system via the data communication interface over a computer network to authorize the client application to access the online content management service system;
• obtain, from the online content management service system via the data communication interface, information about a first content item stored in a cloud storage on the online content management service system;
• display a first interface image by the client application, the first interface image for presenting an identifier of the first content item;
• enable, by the client application, a user to request edit control of the first content item;
• detect, by the client application, that the user has requested edit control of the first content item;
• display, in response to detecting that the user has requested edit control, a second interface image by the client application, the second interface image for presenting a set of one or more selectable editing application identifiers to the user and enabling the user to select from the set a preferred editing application for editing locally the first content item, the set of one or more selectable editing application identifiers capable of including a particular editing application identifier to a particular editing application not installed on the user device;
• receive, via the second interface, a user selection of the preferred editing application, the preferred editing application being different than the client application;
• if the preferred editing application has not been installed on the user device:
• enable the user device to download the preferred editing application, and
• enable the user device to provide authorization information to the online content management service system;
• if the preferred application has been installed, regardless of whether the preferred editing application has provided authorization information to the online content management service system, provide to the preferred editing application item-identifying information of the first content item, the item-identifying information being usable by the preferred editing application to obtain the first content item stored on the online content management service system via the data communication interface;
• if the preferred editing application has been installed, the authorization information has been provided to the online content management service system, and the authorization information has been verified by the online content management service system:
• enable the preferred editing application to save the first content item, as edited, in the cloud storage, and
• upon user request, save the first content item, as edited, by the preferred editing application in the cloud storage;
• and
• if the preferred editing application has been installed, and the authorization information has not been provided to or verified by the online content management service system:
• enable the authorization information to be provided to the online content management service system for verification, and
• until the authorization information is provided to and verified by the online content management service system, not enable the preferred editing application to save the first content item, as edited, in the cloud storage, and upon user request, save the first content item, as edited, by the preferred editing application in a local storage.
