    I've reinstalled Windows 8.1 on my PC (...and B4A), since then I'm getting error message when trying to compile and install my app on my smartphone:

    B4A version 4.30
    Parsing code. 1.96
    Compiling code. 2.13
    Compiling layouts code. 0.01
    Generating R file. 0.46
    Compiling generated Java code. 8.11
    Convert byte code - optimized dex. 14.12
    Packaging files. 4.17

    ZipAlign file. 0.11
    Installing file to device. Error
    pkg: /data/local/tmp/Mindset.apk
    Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE]

    Restarting ADB Server may solve this problem.
    Tools - Restart ADB Server. Device serial: 4df1c2161d418f9f


    Trying to install apk also fails.
    No problem to Install the app on Genymotion emulator with Android 4.4.2.
    I'm able to compile and install other apps on my smartphone.
    My smartphone is running Android 5.1 (but it was the same before reinstalling Windows 8.1 on my PC ...)
    I'll appreciate your help.

    Thanks,
    David.

    Just remove (uninstall) the old one on your phone and try again. It seems that it's not compatible for an update or other things which you might have changed (f.e. removed an SD-Card where it was installed on?)

    Thanks KMatle. As you proposed, removing the installed app resolved the issue.
    Do you have an idea what was the cause of the incompatibility ? after all, it is the same code and environment (PC, Windows, IDE, Code ...).
