What is a working combination of versions of the development tools if I want to develop C++ Qt Android apps? I tried several combinations but they all fail with strange build errors of a simple Hello World test app.

Currently, I have

  • Qt Creator 4.2.1 (based on Qt 5.8.0, MSVC 2015, 32bit)
  • JDK 10.0.1
  • Android SDK 24.4.1-win
  • Android NDK r10e
  • Apache ant 1.9.11

but e.g. that fails with 

Buildfile: build.xml does not exist!
Build failed
Warning: Android platform 'android--1' does not exist in SDK.
Building the android package failed!
  -- For more information, run this command with --verbose.
21:35:44: Der Prozess "C:\EigeneDateien\bin\Qt-5.8.0\5.8\android_armv7\bin\androiddeployqt.exe" wurde mit dem Rückgabewert 14 beendet.

I want to use an open source version.

Please, give a list of tools with correct version numbers and maybe download links.

    JDK 10 won't work, use no later than JDK 8. You do not need Apache ant, else seems OK. have a look at a working combination [here](https://stackoverflow.com/questions/48189272/qt-creator-android-error-platform-sdk-installed/48348201#48348201) – Mohammad Kanan May 10 '18 at 20:00
  • Which one, 8u171 or 8u172? I can see them here: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html – falkb May 10 '18 at 20:43
  • The error stays the same with 8u172 – falkb May 10 '18 at 21:10
  • I don't know how to create 'android--1' and what it means at all – falkb May 10 '18 at 21:34

    The latest Qt (5.10.1) and QtCreator (4.6.1), together with Java 8 and the latest SDK/NDK works perfectly fine. Try building one of the example projects from Qt first, to make shure it not working is not your apps fault. – Felix May 11 '18 at 15:36
  • @Felix They do not offer a download link for Qt-5.10.1 for Android. See here: https://www.qt.io/download-qt-installer How can I get that latest version for Android? They autodetect my Windows and just offer me the installer for Windows. – falkb May 14 '18 at 21:09

    Use the online installer, where you can select which version of Qt you want to install – Felix May 14 '18 at 21:30

The good procedure is to use Qt's online installer (https://www.qt.io/download-qt-installer), get the latest version of QtCreator/Qt, then the latest version of ndk/sdk/jdk and cross your fingers because it does not always work...

I fighted a bt with this in early 2019 and here is a combination that perfectly works for me since then, under Windows 7 and 10.

  • QtCreator 4.8.0, based on Qt 5.12.0. I got it from the online installer by then and archived it, but you can apparently specifically download it from here.

  • NDK r18b

  • JDK 1.8.0_201, can be dowaloaded from this page (find jdk-8u201-windows-x64.exe)

  • Android SDK command line tools "sdk-tools-windows-4333796", available here. Then used sdkmanager to download API platform-tools and android-28. Try sdkmanager "platform-tools" "platforms;android-28"

No need for ant anymore, QtCreator will download and use gradle silently.
