I enabled "USB debugging" and "Wi-Fi debugging". But how does the "Set up Wi-Fi" button work? I tried to press it, but when I disconnect the USB cable, the connection is lost.

Are you using layouts?

"it is open in new window instead of in QGraphics view" - show your code and also tell us what OS and window manager is running on your board.

@Ivelin Hey any luck with foreground service? I
am trying to do this too but no doc/reference

I caused the problem myself: Check for details

Not sure if anything I learned applies to you.

@esnosy said in Unable to debug Android App (Windows + Qt Creator 12 + LLDB):

EDIT: I take it back

Does that mean, you are still struggling?

@jsulm Thank you for your confirmation. AI, whether it's GPT-3.5 or 4.0, cannot distinguish whether it is referring to Qt 5 or Qt 6, which is really frustrating!

Anyone has any idea?

@himanshu-d Have you solved this problem? I am facing the same issue.

Never mind.. This is, apparently, the same issue as https://forum.qt.io/topic/143745/qtvirtualkeyboard-fails-on-embedded-buildroot-5-15-8. Switching from GCC 11 to GCC 10 "fixes" the issue.

@aashishqt You're welcome
to enable eglfs, in your local.conf add
DISTRO_FEATURES_remove = "X11 wayland"
then in qtbase_%.bbappend add
PACKAGECONFIG_append = " eglfs"

qtbase_%.bbappend is found in meta-qt5 under recipes-qt, qt5 folder.

@Kaijun said in yocto build on qtxmlpatterns failed on Qt5.11:

When I built qtxmlpatterns with yocto for arm, it failed with following messages, has anyone experienced this issue?

When I built qtbase and qtbase-native, they use configure, but qtxmlpatterns uses qmake to configure instead, why?

@Poldi Given that nobody has replied so far, do you need more info?

@JonB it's a clever idea but unfortunately doesn't work with Qt Creator.

I tried setting Android NDK location to C:\android-ndk-r20b... but then there are errors in Qt Creator immediately:

Android NDK directory structure is incorrect Android NDK installed into a path without spaces.

For fun, I tried the following and it works. I can compile in Qt Creator now but it's such a roundabout way to hack this.

Projects > Android for arm64-v8a (Clang Qt 5.13.2 for Android ARM64-v8a) > Build under Build Steps click on Add Build Step drop down to get an option Process Custom Step click on Custom Process Step on the top right corner of the new step (only when the mouse hovers over the step) there's a little upwards pointing arrow, click on it until it is under the qmake step but before the make step in the Command field: python in the Arguments field: full path to a Python script that I'll copy below

Basically, it does the following:

run qmake as usual, which will generate a Makefile with faulty NDK path run a custom Python script to change C:\android-ndk-r20b to C:/android-ndk-r20b in the Makefile run make as usual

My first attempt was to replace all \ with / in the Makefile but it failed, so I modified the script to only replace the \ with / in the NDK path (as you'll see in the script below).

In Linux there's probably a much simpler way to do this with just a sed command but I'm in Windows and don't feel like spending any more time on this issue. However, also in Linux, this likely wouldn't be an issue to begin with as everything likely already uses /.

I can now compile the project in Qt Creator 5.13.2.

Here's the Python script I'm using, note that it's just a copy/paste/modify from the first search result I found as I'm not strong in Python. Also, this requires that Python is installed and found your PATH (i.e. in Command Prompt, run "python --version" if it doesn't work, then this approach won't work for you). If you modify your PATH you'll need to restart Qt Creator.

Also, the path to my python script is currently absolute, i.e. C:\full_path_to_script\fixup.py. I didn't spend any time trying to add it to the project and use a proper relative path/environment variable for the script.

Here is the Python script I used:

import re def case_insensitive_search_and_replace(file_path, search_word, replace_word): with open(file_path, 'r') as file: file_contents = file.read() pattern = re.compile(re.escape(search_word), re.IGNORECASE) updated_contents = pattern.sub(replace_word, file_contents) with open(file_path, 'w') as file: file.write(updated_contents) # Example usage # Note: This is the full absolute path to the Makefile that is auto-generated by qmake: file_path = r'C:\code\project_path\build-project_path-Android_for_arm64_v8a_Clang_Qt_5_13_2_for_Android_ARM64_v8a-Debug\Makefile' # you'll need to change this to match your NDK path search_word = 'C:\\android-ndk-r20b' replace_word = 'C:/android-ndk-r20b' case_insensitive_search_and_replace(file_path, search_word, replace_word)

@Tahar it is likely, yes.

Hi,

To complement WikiManiac's answer, I have recently re-discovered pyqtdeploy.

Although there is documentation online about pyqtdeploy, it is hard to figure out specific steps to set up the tool.

I have decided to update the documentation and upgrade a bit the tool on my side first.

If you wish to convert your PyQt5 apps into Android apps, follow the in-depth tutorial on https://github.com/achille-martin/pyqt-crom.

There is no official support for PyQt6 in my repo yet though. So please start with PyQt5 to build prototypes and I am expected to add support for PyQt6 later.
