Hey,
This seems the same as QTBUG-129704 that I saw few days ago, it’s now flaky in
CI and I haven’t reproduced it locally, it’s being worked on though. It would
be helpful if you provide a minimal reproduction project for it under that
ticket.
Best regards,
Assam

Hi Nuno,
it seems your problems with package name and set_target_properties are fixed
now.
you're trying to port an Android app to 6.8.0 CMake
is this a 6.8.0 QMake app or 6.7.x or ??

Assam,
Thank you very much for your reply. It helped a lot.
Unfortunately I’m still having the same crash when launching the application
and I don’t know what this means:

Can you please enlighten me?
Thank you!

Hey,
We have some examples that use that, you could take a look at

Ekke,
Thanks once again for the reply. I had the following when using the snippet you
provided to me:
[cmake] CMake Error at CMakeLists.txt:48 (set_target_properties):
[cmake] set_target_properties called with incorrect number of arguments.
Any ideas?
Hi Nuno,
please paste your set_target_properties command
Is there any official Qt project example for more advance usage? For instance
when we need to extend the activity?
In all this years, the experience I have with Qt for Android is that if I need
to update Qt and I need to update and android app, I always stumble on a big
mess that makes me invest a lot of time. This is not a Quick approach…
to be fair: Google and Apple always are changing workflows, APIs,
requirements...
I don’t know if other developers share the same opinion.
yep - always the same. this time it was even more time to spend:port apps from
5.15 to 6.6 and then port from QMake to CMake.
because it's not so easy to get the needed informations I'm writing my blog
pages ;-)

Best,

Nuno,
you also have to set the target properties
set_target_properties(${MY_APP}
PROPERTIES
QT_ANDROID_PACKAGE_SOURCE_DIR ${QT_ANDROID_PACKAGE_SOURCE_DIR}
QT_ANDROID_MIN_SDK_VERSION ${QT_ANDROID_MIN_SDK_VERSION}
QT_ANDROID_TARGET_SDK_VERSION ${QT_ANDROID_TARGET_SDK_VERSION}
QT_ANDROID_PACKAGE_NAME ${QT_ANDROID_PACKAGE_NAME}
QT_ANDROID_VERSION_NAME ${QT_ANDROID_VERSION_NAME}
QT_ANDROID_VERSION_CODE ${QT_ANDROID_VERSION_CODE}
)
hope this helps
BTW: you also can take a look at https://t1p.de/ekkeCMakeAndroid
(have to tune some parts of my Qt-mobile-CMake docs, but ATM I'm still with 6.7
and QMake - waiting for a fix because of nested QML dirs coming in 6.8.1)

Ekke,
Thanks for your reply. I’ve tried to set in my CMakeLists.txt:
set(QT_ANDROID_PACKAGE_NAME "com.imaginando.drc”)
And it did nothing. The problem persists. And when running the application I
have:
E AndroidRuntime: FATAL EXCEPTION: main
E AndroidRuntime: Process: org.qtproject.example.drc, PID: 13589
E AndroidRuntime: java.lang.RuntimeException: Unable to pause activity

Also, in the bug report someone says:
Qt 6.7.2 and 6.8.0 will support for using namespace in build.gradle and using
AndroidManifest.xml without <package> tag.
The new CMake property QT_ANDROID_PACKAGE_NAME comes to 6.8.0.
For Qt Creator 14, it will support using namespace from build.gradle and
support using AndroidManifest.xml without <package> tag.
And none of this options work also. I’m using Qt 6.8.0 with Qt Creator 14.0.2
Any ideas?
Regards,
Nuno

Hi,
I’m trying to port an application to Cmake in Qt for Android.
I’m not able to set the package name. I set it in QtCreator, it gets modified
in AndroidManifest.xml but then, when AndroidManifest.xml is copied to the
build, it has a different value and I have warning from gradle:
Value set in QtCreator: com.imaginando.drc
package="org.qtproject.example.drc" found in source AndroidManifest.xml:
/private/tmp/drc/build/Android_Qt_6_8_0_Clang_arm64_v8a-Debug/android-build-drc/AndroidManifest.xml.
Setting the namespace via the package attribute in the source
AndroidManifest.xml is no longer supported, and the value is ignored.
Recommendation: remove package="org.qtproject.example.drc" from the source
AndroidManifest.xml:
/private/tmp/drc/build/Android_Qt_6_8_0_Clang_arm64_v8a-Debug/android-build-drc/AndroidManifest.xml.
I’ve tried to set it build.gradle as it is below without success:
android {
namespace “com.imaginando.drc"
Any ideas on how to workaround this or what is the best practice?
Thanks!
Nuno
