what can be wrong? am i stupid?))

Hello,

You’re using the Database API to save your GeoPoint. However, when working with geolocation data, you should be using the Geolocation API:

Cant understand how i can set pointer where in my DB necessary tables where i want to save my geoObjects?

Geo points are saved in a separate storage called the geolocation storage. That is why there is separate API for it.
