How to survive app from hard reset android phone?

i've seen apps like Cerberus which can survive hard reset of phone. I want to add similar functionality in my app that has security features such as anti theft. So my question is: How to create a app that will survive hard reset to preserve some data that might be even used for further purposes, How can i prevent my app from hard reset of device?

I went through the .zip file from one of the app which is used to flash the app to the ROM but it didn't clear my doubts , can anyone clear the idea about how it can be done

Thanks in advance!

Solution

  • You can only do this if you have root permissions by moving the APK to /system/app. SuperSu, etc. offer this as an in-app feature. If you really want reliable 'security features' though, the app(s) should be part of the firmware, anything else is snake oil.
