Hello,

is there a method to get the sharing details of the App Designer into my code.

For example I want to display the version and name of the app somewhere in my GUI without programming it directly. So when I create a new version of my app I only have to change the information in the sharing details and it will be updated in my GUI automatically.

Thanks!

I also would like to show the version in the userinterface of my app and access it programatically

When you go to package the app there is a field for the version number.

When the app is installed, the user can view the version number by hovering over the app.

@Taylor, unfortunately your answer does not address the question being presented. @Maxi in addition to the a number of other App Creators are looking for a way to programmatically extract the version information entered into Version field when packaging an application. Currently, if a creator wants to provide a version display within their application that any user can readily access, this information must be hard coded into the application.

Speaking for myself and depending on how my application will be used, I may need to package the application into an .exe file and validate that version. Validated versions much be retained for audit purposes and use in accredited testing services that we provide. These validated executables also need to provide a means to display all necessary version information from with the application itself. Executable files do not have the ability to app icon in MATLAB since they run via runtime software and not MATLAB itself. Therefore I like to include a Help>About Application menu item that will display the author, application version, MATLAB version used to create the application, and the date the application was created. If I update my application it becomes cumbersome to the have to remember each and everytime to change all of the the hard coded information.

Forgetting to update the hard code version information happens too often and may not be noticed until well after the application has been released to an end-user. By utilizing the Version field when packaging and using a programmatic extraction approach, App creators would only need to update the version number in that single location, since it is obvious the application and/or executable files store this information when being packaged.

@Maxi @Allen @Adee Is this more what you're looking for? https://www.mathworks.com/matlabcentral/answers/2050932-how-to-access-app-version-number-from-inside-the-app

@Taylor, it doesn't seem to work - the code you pointed to takes the version number from the executable file, not from the app designer metadata.

The information in "Sharing details" is not propagated to the execuable file by the Matlab compiler. The version number can be specified using the "-W" switch but it still poses the problem of how to get the right number from the mlapp file...

Also, these details should preferably be available when running the app under MATLAB (before it is deployed).
