Don't know if I have the terminology correct, but I recently install TeamViewer Quicksupport from the Play Store. After it installed, I had to download an 'Add-on' for Samsung (I have no idea why it is needed, but I don't care, really).
This 'Add-on' has it own entry on the Play Store and you can download it without installing QuickSupport first, but you cannot 'Open' it.
I cannot find any information online on how to develop these 'Add-ons'. I do not even know if it is possible.
What I want to know is, how can such 'Add-ons' be developed and deployed. Any links to information would be greatly appreciated. I would like to find out if this would work for a design whereby you create a 'base' app with X features and then if needed, you can download 'Add-ons' to get other features? Kinda like modules?
Here are links to the Apps on PlayStore:
