You cannot create a standalone databases for use on the iphone, ipad, or ipod, all databases on the iOS requires filemaker GO. Filemaker does not support android. Filemaker Go 11 is required for databases created on filemaker 11 and prior. Filemaker Go 12 is required for databases created in filemaker 12. I believe Filemaker GO 11 is not available any more for purchase, you can verify on the app store. It used to be $39.99. Filemaker Go 12 is Free.
You can create a databases with filemaker and then download Filemaker Go to the device and then use an app called "App Maker" to make an icon on the home screen to automatically open the database in Go.

You can create a databases using Instant Web Publishing so that your databases can be access by a web browser which should run on android
