Alternative for mydac and unidac

I just want to ask if there are other ways to connect my mobile app in a remote MySQL database other than UniDac or myDac which is free.

Im using delphi xe8 for development.

I already research a lot about these, and I also tried a lot of options like firedac or dbexpress, still not getting any solutions. i tried mydac and it works, the problem is for now, i cant pay for the license so im looking for an alternative to mydac or unidac.

most research results points me to firedac, dbexpress or devart's liteDAC which is also licensed. what I did is this, i bought a host in a cloud server provider which I can create a remote database on it. so I created a database in there, which I will use it for my mobile app. i cant use firedac, it says i needed to get libmysqlclient.so or libmysqld.so and put it on a the path where the exe is, i just wonder, what could be the exe that xe8 points here?

i cant even use dbexpress also. when I open my app, It just give me a blackscreen, and dont even show the form. I tried to wait for a minute or two, hoping that it was just trying to connect to the database, still in the same black screen. i put the configuration process of the dbexpress to the form's show event.

thanks a lot for any help.
