Does copying Android application from device to device copies the data as well?

I want to protect my application from being copied by users from device to another device. I know that wont be possible because once the apk is installed any third party application may be able to copy or extract the apk. I mostly care about the private data of the application rather than the apk itself. So, my questions are :

1- Can I protect the apk from being copied to another device by the user ?

2- If user copied an application from device to another (e.g. via third party app or by bluetooth) will he/she be able to copy the private data as well ? If yes, can I protect that ?

Thanks in advance.

  • you can use google licence in your app even if its copied from rooted device it wont work until its downloaded from playstore

  • second /data/data/<packagename>/ can be copied from rooted device

To answer briefly, AFAIK, No. Regarding the single questions:

  1. if device is rooted it's really easy to access the /data/app/ dir and copy your apk, even on the device itself.
    For un-rooted devices you need to issue some adb commands. For reference, look here:

  2. the same applies to /data/data/com.example.app/ for the private app's data. Just different folder and possibly many files to copy.

Basically the difference it's not in having root or not, but in the ease of realization.
