    Hey guys :)

    I used this library to protect data

    Before the encryption, the database size was 104 MB, but after the encryption 98.2 MB.
    (The volume of the database was reduced to 6 MB).:D:D


    After the release of the program, we see that the APK file size has changed from 22.5 MB to 104 MB !!!!!! o_Oo_Oo_O

    If after the encryption the volume of the database is reduced 6 MB, how is the program size larger(22.5 MB ==> 104 MB)? :eek::eek::eek:
    Could you describe this phenomenon to me?

    Yes. The APK file is a regular zip file.

    The encrypted database format is "random" so compression will not do anything. Unlike the regular db where compression can be effective.
