Building Android package with Qt5.15.0 works fine but Qt5.15.2 fails

[Frans Fürst]

Hi, me again, trying to build the demo for Android!

After I failed to build the demo with a self-built Qt I'm now using a pre-built Qt for Android in order to begin with a working scenario (as I should have in the first place).

Building against Qt5.15.0 works fine - but since it seems to be the stable version for a long time now I tried to use Qt5.15.2, using the exact same setup as with Qt.5.15.0 before.

But now - after seemingly all of the compilation runs well, building the Android package throws an error:

ANDROID_SDK_ROOT=/opt/android-sdk/ \
ANDROID_NDK_PLATFORM=android-29 \
ANDROID_NDK_ROOT=/opt/android-sdk/ndk/21.3.6528147/ \
python3 ./build-demo.py --target android-32 \
--qmake /opt/Qt/5.15.2/android/bin/qmake

...

Welcome to Gradle 5.6.4!

Here are the highlights of this release:
- Incremental Groovy compilation
- Groovy compile avoidance
- Test fixtures for Java projects
- Manage plugin versions via settings script

For more details see https://docs.gradle.org/5.6.4/release-notes.html

A problem occurred evaluating root project 'android-build'.

Searching for "Failed to apply plugin [id 'com.android.internal.application']" returns me a couple of gradle reated (but old) results which recommend to modify "build.gradle" to use a more recent version of gradle but this doesn't seem to have any effect.

I will now try to analyse the differences between qt5.15.0 and

qt5.15.2 but maybe someone has done this before and give me a hint?

Thanks, Frans
