If you have anything compute-intensive enough to affect battery life in an Android app, you really ought to use the NDK, and Go will probably be officially supported: https://docs.google.com/document/d/1N3XyVkAP8nmWjASz8L_Ojjnj...
Or if you want Android/iOS portability, find a common API for SQLite and implement in C.
