    after the update i can’t run application for ios and android.

    With iOS i have a compilation error: “QApplication and VApplication not found”

    on Android i have:

    “Android build SDK not defined. Check Android settings.

    Error while building/deploying project AppPlayground (kit: Android for armeabi-v7a (GCC 4.9, Qt 5.9.0 for Android armv7))

    When executing step “Build Android APK””





    Hi Nicola,
    It can be a known issue(Qt internal problem), could you please check this post and solution provided there?
    Does it help you?

    If not, to double check, you use Qt 5.9 kits to build your projects?



    Nothing! With “normal” Qt/QtCreator i can build Ios and Android app.




    Hi Nicola,
    I am afraid I can’t help you.
    If all the common fixes do not help and you use right kits then it’s probably beyond my knowledge.
    Lets wait for Felgo team.

    Hi Nicola!

    the issue “QApplication and VApplication not found” usually hints that the Build Kit that your project uses for building misses all the Felgo library/module files.

    As a first solution step, please try uninstalling / re-installing your Android and iOS Kits with the MaintenanceTool. To check whether VPapplication and thus probably also the other library files are really missing you can:

    • Go to Felgo installation directory
    • See whether the “5.9/ios/include/” folder contains a “VPlay” directory with “VPApplication” and “vpapplication.h”

    If a re-install of the affected Kits does not help, please try installing Felgo from scratch as there is probably something broken with the installed packages and Qt module/component management of your Felgo installation.
    When testing if it works, please also make sure to get a fresh and clean build with new Qt Kit and all installed modules by:

    • Close Qt Creator
    • Delete the *.pro.user file of your project
    • Delete the shadow build directory of your project (e.g. build-<project>-iphoneos_clang_….)
    • Open Qt Creator, then open your project
    • Re-configure the desired Kits
    • Right-click the project and select “Clean”, followed by right-click and “Run qmake”
    • Rebuild / Run the project

    Let me know if the suggestions help!





    for Andoid i done a downagrade to sdk 25, for ios resolved cleaning and reinstalling all Felgo. Now i have the message that the my license key for the app is wrong and i must generate a new.


    Felgo Team

    Regarding correct license key setup, please see: https://felgo.com/doc/vplay-publishing/#v-play-license

    Can you double-check that the app identifier and version configuration in your Project-Info.plist, config.json and AndroidManifest.xml matches the app identifier / version of the license key?

    For Android, please also make sure that android/build.gradle uses the correct app identifier for defaultConfig.applicationId.
