Embeded Auto Executable Payload in Safe Looking Image or Other Files (Android)

if i wanted to send a Auto Executable Payload embeded in a seemingly safe looking file like a photo, mp3 or whatever to an andoid phone, so i can take control of the phone. how would i go about that?

i know how it works sending an embeded apk file, but then on the phone you would have to manually install the apk file. is there a way to make it install automatic, without installing the apk or the payload embeded in an other app so the person doesnt know what he/she is installing?
