How to Develop Android Database Applications in RAD Studio XE5

Not so long ago, in RAD Studio XE5 there was introduced support for Android application development. On the Internet there can be found a lot of information about Android application development in Delphi XE5, but when it comes to development of database applications, it becomes much more difficult. The point is that the components and drivers included in the RAD Studio XE5 distribution (for example, FireDAC and dbExpress drivers) have severe limitations: on Android and iOS platforms, they support just 2 databases — SQLite and InterBase. And what to do when you develop a serious business-application, that requires remote connection to Oracle, MySQL or PostgreSQL from Android?
