Static Lights Don't work on android

Hello. I don’t know much about UV And Light maps. all my assets are Sprites. I couldn’t find Anything UV Related in the sprite editer. I Created a New project turned everything UV Related in the mesh editer on but it didn’t work.
And Also i realised the Build Lighting Turns off in android preview, so i cant even build lights. I can build precompute static visibility but at the end it give and error that says (world setting light needs to be rebuilt)
