Error when build & run Qt app on Android for x86 and armeabi-v7a kit



  • Hello everybody,
    I've been trying to develop Android app with Qt Creator 5.7. But when I tried to deploy on device (both emulator and real device), I got this message in Compile Output and failed:

    Generating Android Package
      Input file: D:/Cac project/C&C++/Qt/build-AppSample-Android_for_armeabi_v7a_GCC_4_9_Qt_5_7_0-Debug/android-libAppSample.so-deployment-settings.json

    Error while building/deploying project AppSample (kit: Android for armeabi-v7a (GCC 4.9, Qt 5.7.0))
    

    I've already downloaded the lastest version of JDK (JDK 1.8.0_102), NDK (ndk_r12b), Android SDK and Apache Ant (Apache Ant 1.9.7). I've also tried to check and uncheck the checkbox "Use Gradle instead of Ant" but still got the same result.
    Can anybody explain me what I did wrong or give any solution for it. Thanks a lot.

    C&C++

    this is not a valid directory name on Windows (at least you cannot use it on the command line)!
    Rename it in something like CandC++
    And avoid to use blanks in paths.



  • Oh I'm almost forgot, I tried creating a new app in another path and it worked well. Thank you very much !
