Paper has not been designed for such a use case but here is what you can do:

  1. Copy *.pt file from the internal location of one app to the any shared folder (sdcard).
  2. Within another app copy that file from sdcard to the internal folder of the app.

To locate original *.pt file on disk you can use Book. getPath() method.

This method is dangerous because different apps may run on different class signatures (you may change data classes which has been saved in another app). I'd rather use some common formats like json to export/import data.
