Which database to choose in order to implement multi-platform access (Android + iOS) with the least bloodshed?

Question

Android

I am designing a desktop application in c# that works with a customer database for which in the future it may be necessary to organize access from mobile clients (Android + iOS). Actually a question: what DB initially to select that with the smallest blood to carry out such multiplatform access?

Answer 1

The fact that your mobile clients somehow affect the server database raises some concerns.
On your desktop / server side, raise a wcf service or mvc api or hardcore on sockets and transfer data via json / xml / bytearray through class serialization. For good reason, mobile clients should not guess at all that on the server, in addition to the http gate, there is still some kind of database.

Answer 2

For an Android application to be friends with a web service via SOAP, you can use the KSOAP2-ANDROID library. Tested, working. True, there are small kosyachki, but developers rule on the go. 1 my bug was closed :)
Look towards REST/SOAP web-service.
