Unity Android How to open file in explorer?

Question

Android

I need to open a file from an android application (i.e. so that a menu appears in the application with the choice of the desired explorer, and in the explorer so that you can select a file of a certain format).

Answer 1

Well, the simplest (and probably correct) in this case is to find a similar code in Java / Kotlin, compile it into AAR, and use it as a plugin in Unity. Well, yes - compile taking into account the work of the unit with plugins ...
And they also hope that your activity in the unity will not be lost along the way)
