hi, im john.
i wanna be helped by you.
some time ago, i was in the process of developing android app by only blueprint, but i have a problem.
i wanna protect apk backup of this android app, but i think there is no way…
some google search results talk to me after inserting the device unique number into my app as source code, when i run this app, let the app decide whether it is running by comparing the unique number.
do you have other opinions? if you have or know method described above, help me please. thank you.
