    @NikhilJ In the middle of the first screenshot you can see a combo box "Android build SDK" - there is nothing selected.

  • @jsulm yes that's the reason. I don't know why platforms are not showing there. I have already give complete SDK path in screen shot 3. And SDK path in environment variable as well. can u please help me to know the reason.
    I am using 64 bit windows 10. with latest android SDK & QT version.

    @NikhilJ Is there nothing in "Android build SDK"?

  • @jsulm Yes i am unable to select platform in this drop down.(Empty).

  • @NikhilJ I had the same problem, but I have installed the latest Qt 5.9.2, the latest JDK 1.8.0-151, the latest Android NDK (android-ndk-r15c), the latest Android SDK Tools (26.1.1), the latest Android SDK Platform-Tools (26.0.1), the latest Android SDK Build-Tools (26.0.2) and also I have installed all Android SDK for API Level from 16 to 26, and now I do not observe the problem.

    Also check: can you invoke java -version from command line? What do you see? It must be JDK 8 or early.

    Qt Creator must be available to call sdkmanager, avdmanager and etc. To do it you have to set the JAVA_HOME environment variable to JDK 8 and put JAVA_HOME/bin into the PATH environment variable before calling Qt Creator.

  • If I remember correctly this problem may be due to a bug in QtCreator that puts empty BuildTargetSdk keys on the .pro.user file. Try editing that an add appropriate values for the key (at many locations), e.g.


  • @AnatolyS Hello, i had the same issue, but after removing a old jdk and reinstalling JDK version 8 update 151 everything works.
    I have not set the JAVA_HOME environnement variable.
