Android build SDK not defined. Check Android settings. Qt 5.9.1, QtCreator 4.4.0, with Android Studio.

Open your ... \tools_r25.2.5-windows\tools\android.bat

Install at least the version of the SDK API that you are using.

@joaopagotto Yeah thanks for your reply, I got it working earlier already, by downloading the last release of the SDK 25 version, 25.0.3. Didn't have to update the tools, the latest tools installed by Android Studio work just fine.

@ind1g1ne0us
seems like this is now already fixed with QtCreator 4.4.1/Qt 5.9.2

[joaopagotto]

@raven-worx Yes, in this version works ! =D

Hello. Issue not resolved on Windows, with QT 5.9.2, QT Creator 4.4.1, Android SDK Tools 26.1.1.

[Serieus_developer]

@Cdr_sfy same here as you

[joaopagotto]

Try delete folder C:\Users\user\AppData\Local\QtProject and uninstall all Qt, and install new version of Qt.

I reproduce this problem on Win 10, Qt 5.9.2, QtCreator 4.4.1. But on macOS I haven't got problem. I tried to reinstall Qt, but didn't have any result. Can somebody help me? Thank you!

[Cdr_sfy]

Same problem with Qt 5.9.2, Qt Creator 4.5.0 beta1, on Windows 7 or Linux Mint.

@Cdr_sfy check this https://forum.qt.io/topic/83930/android-build-sdk-not-defined-check-android-settings/6

[Cdr_sfy]

@AnatolyS Thank you for this help Anatoly :-)
The problem was due to my JDK 9 installation. Removing it, and going back to JDK 8, all is working well now !

[AnatolyS]

@Cdr_sfy perfect, nice to hear that you have solved the problem

OK, after many hours try out I finally find out how you can fix it.

• Download and use Android NDK r10e separately (don't install it through SDK Manager)
• Download and use Android SDK without Android Studio (download android tools from official site) Qt Preferences will installs all needed packages (build tools , platform tools, sdk tools, platform android-28)
• Install and use Java JDK 8 (not newer)

Please note that installing SDK packages through Android Studio will not be detectable by Qt
