Mobile and Embedded

Hi, If memory serves well, it was usually around every three releases. 5.6 -> 5.9 -> 5.12 -> 5.15. 6.5 -> 6.8

I have done some more research. Using Android services with Qt is problematic. There is however a simple flag in the manifest file that allows a QT app to keep it's main thread-loop running when the app is in the background, so that it can be used for audio playback, or receiving push notifications that can trigger actions in the main Qt thread, when the user is not actively using it. <meta-data android:name="android.app.background_running" android:value="true"/> This setting, in the application entity gave me the most important functionality I was looking for.

Hi @Isaias , I have achieved to run two displays (LVDS + HDMI) using Wayland Weston, and running an instance of Weston in clone-mode: /usr/bin/weston --modules=systemd-notify.so --tty=1 --device=/dev/fb0,/dev/fb2 --clone-mode Here, the content of fb0 is cloned to fb2. It works, but on my SoM (i.MX6 based), I now experience severe lag on the LVDS screen and the touch inputs are also delayed. Additionally, I had to tune down the HDMI resolution to 900x600 to get it to work. On my SoM, using DRM/KMS is not an option, since my kernel version does not support it. I use fbdev instead. Maybe this helps a bit. If anybody has another solution, please share!

@ekkescorner , your post in another thread helped: https://forum.qt.io/post/829606

And here's what Qt says, if you want to opt-out from Android-35 edge-to-edge: you have to add styles.xml and add in Manifest... activity... android:theme="@style/NormalTheme" see the details here: https://codereview.qt-project.org/c/qt/qtbase/+/630376

Yep, I was able to install everything I need from Qt6 on RPi Ubuntu. Setting... set(CMAKE_PREFIX_PATH "usr/lib/aarch64-linux-gnu/cmake/") ...allowed CMake to find everything. Like one of my highschool maths teachers used to say, "Don't do it how I've shown you on the board."

it is Webview issue. will update soon when find the fix.

@Pruza For android build VS C++ compiler is not needed anymore. You can simply do it with QtCreator.

@petero3 does your code work on Ubuntu or Redhat? Is wayland applied in Yocto? If yes, the following envs are needed. #ifdef YOCTO setenv( "DISPLAY", ":0", 1 ); setenv( "GDK_BACKEND", "wayland", 1 ); setenv( "QT_QPA_PLATFORM", "wayland", 1 ); setenv( "XDG_RUNTIME_DIR", "/run/user/1000", 1 ); setenv( "WAYLAND_DISPLAY", "wayland-1", 1 ); setenv( "QT_QPA_FONTDIR", "/usr/share/fonts/truetype", 1 ); #endif

@cristian-adam Tested qtcreator 17.0.1 with my Samsung A06 Phone and Tab9 Tablet and both now deploy correctly. Thankyou.

Thank you. We have Laird's version of wpa_supplicant in our Yocto. Update is: We've done a POC using wpa_ctrl.c. Couple of issues currently: Initial connection works, but after restart, or reboot, wpa_supplicant fails to parse the conf file: failed to parse psk '*'. That was set using set_network ... psk ... scan while connected only shows currently connected SSID We've also done a POC using Qt Device Utilities and adding ConnMan to our Yocto too: That works better in terms of persisting the password. To stop ConnMan from trying to manage wired ethernet too, needed: [General] NetworkInterfaceBlacklist=eth0,eth1 Scanning for other Wi-Fi networks, while connected to one, is still an issue.

I got this issue when I had VPN running.

@Adla Thank you for sharing. GoogleMobileAds.framework in your Pods.zip works well. May I ask you how you generated this Pods.zip? I tried to generate it but it didn't work as yours. Here is my steps. Run Xcode Create an iOS app project with Interface: Storyboard Language: Objective-C pod init Edit Podfile pod 'Google-Mobile-Ads-SDK' pod install --repo-update But with the resulting GoogleMobileAds.framework, I got many errors, Undefined symbols for architecture arm64: "_$sBOWV", referenced from: $s15GoogleMobileAds24GADMarketplaceKitSignalsCMf in GoogleMobileAds(GADMarketplaceKitSignals.o) "$sScA15unownedExecutorScevgTj", referenced from: $sScTss5NeverORs_rlE8priority9operationScTyxABGScPSg_xyYaYAcntcfCyt_Tgmq5 in GoogleMobileAds(GADMarketplaceKitSignals.o) "$sScAMp", referenced from: _symbolic ______pSg ScA in GoogleMobileAds(GADMarketplaceKitSignals.o) ...

@SMF-Qt cool :)

@danish777 Thank you! But I noticed that the same code appear twice in two git repository. (or may be the sub Android Studio project is a temporary one so does not need a repository?) And additionally, the gradle files is not identity so reproducibility might be a problem. Is this the commonly used approch in Qt for Android projects?
