Publisch you project as a maven artifact and have you users include the dependencies like that, or build a fat jar.

it is a project for private purposes so I cannot use maven. How can i build a fat jar (actually

aar

)?

Depends on the build system, for example in gradle you would use the

shadowjar

plugin.

It is built using gradle. I don't think

shadowjar

will work, since it is an android library not a jar.

An android library is a jar.

No, An android library is a jar that is embedded resources and other stuff, aka

aar

.
