Help with How to Bind Android Rat/Payload into Images

Hello world! I have been looking around and I only seem to get info on how to embed (exe.) RATs and payloads to images.

I was wondering if there could be ways in which someone may embed android RAT and Payloads (.apk) inside a picture (png or jpg) and when victim downloads, it automatically starts.

links or tutorials will be highly appreciated and thanks for the help!
