how to make and app stay in mobile even after factory reset is done

Hi All,

I am developing a tracking application for android mobile. I came across a problem for which i need a solution. Can you guys help me making an app once installed in android mobile should stay even after factory reset is performed.

Thanks

Well, an indirect way of doing that is to make your app able to work COMPLETELY from an mSD card, which of course, is not molested during a factory reset. Folks can use OTG or if they have built in mSD card support it may work for them. It's a round-about way but something to consider.
