    Hi,
    can i decompress apk created with B4A then inject additional data then compress it again to APK ?
    the idea ,is to make standard APK for restuenat (for example),client well be able to use desktop app to store his special data ,then desktop app will rebuild his apk

    I think it is signing things in the apk file which is just a .zip file.

    chaning files inthere might lose the signing info.

    there are ways with 3rd party tools to repackage an apk tho but I never tested them.

    why don't you store his info on a website backend and pull it in in the open over http?

    you just need a login and password to pull in the right data for the specific user/restorant.

    if it doesn't work then it's probably because that signing stuff gets removed or messed up.

    like I said you download that set of data (customer name, logo, title, his products etc) to the device and store it locally for offline access.

    you can add a sync button or do a version check at app start to pull in new data.
