Android Question Open Activity from another App

[Blueforcer]

I need something like a Pluginsystem.
A main app wich take care of all the plugins and overlays for settings etc. and a "pluginApp" wich do some graphic stuff and logics by its own.
Therefore i search for a way to open an activity from one app in my mainapp (not the complete app but Like app in App).
Plugins will not be third party apps, but my very own.
Is this possible?

Why make things more complicated than they should be?

Create an app with many activities or B4XPages.

Because it should be like that. Trust me, there is a reason for that.
Imagine you ship every smartphone with all available apps pre-installed. Doesn't make sense.
You go into the appstore and just install the apps you want or need.
That's how my app should be like.
Extend 'functions" during runtime.

Maybe a kiosk-mode app, where your main app is configured to be the launcher?
One of its functions could be the searching and downloading of new apps and their updates.

In other words, you define a close-world system for those devices.

ps: just an idea, I have non direct experience on this matter
