I have to check in detail if I can find some free time, but maybe 
in dub.json of d_android a postGenerateCommands line could be 
defined which calls a dub single package responsible for copying 
the binary to the right place depending on the actual 
architecture.

"preGenerateCommands": ["$DUB copy.d"]

Inside of the coding of copy.d all needed information can be 
retrieved from environment variables (see list of environment 
variables here 
https://dub.pm/package-format-json.html#environment-variables).

Kind regards
