Correct way to set database path for assets/external

[bzwirs 4]

Delphi 10.4.2

 

I want to use assets/external when deploying a database file to an Android device.  The device doesn't actually have any external storage (sd card) so the installation auto creates a ./external directory in the internal app directory.  What is the correct way to set the database path.  Documentation says to use 'TPath.Combine(TPath.GetSharedDocumentsPath,'database.db') when using assets/external yet when I use this the app cannot find the database file. 

 

Can someone please advise me as to where I am going wrong with this.

 

Thanks in advance
