Salesforce: User current app

Question: is there a way to check what is the user current app?

Answer: yes, but only for Lightning.


UserAppInfo
Since API version 38.0, Salesforce introduces an object called UserAppInfo, this object stores the last Lightning app users logged in to.

Sample query: SELECT Id, UserId, AppDefinitionId, FormFactor, CreatedById, CreatedDate, LastModifiedById, LastModifiedDate FROM UserAppInfo WHERE UserId = '00580000004JEfS'

Notes:
- AppDefinitionId: the ID of the last Lightning app that the user logged in to.
- FormFactor: The relative size of the app as displayed, values are:
     Small—suitable for a small device like a mobile phone
     Medium—suitable for a tablet
     Large—suitable for a large display device, like a monitor

Since AppDefinitionId is updateable, this means we can mass update the users' app.


AppDefinition
This object represents the metadata of an app and its navigation items. This object is available in API version 43.0 and later.

Sample query: SELECT DurableId, Label, UiType, Description, DeveloperName, MasterLabel, NavType, UtilityBar FROM AppDefinition ORDER BY Label

Notes:
- DurableId: instead of Id, DurableId represent App Id as in use for UserAppInfo
- UiType: option: Aloha for Classic, and Lightning
- NavType: option: Standard and Console
- UtilityBar: only available for Lightning
