恢复出厂设置后如何防止卸载

Question

I have made a security app, and I want to make it more secure. Are there any means by which I can prevent uninstallation from the device, even by a factory reset?

Answer 1

The simplest way I know to do that is converting you app to a System App (just like those ones that come in your phone from factory). Although you will need to make root on your phone for this. With your rooted phone, install Link2SD app and convert your app to a System App.

Answer 2

只有在定制的Android系统上才有可能。
