Oh wow ok I will try it. I will tell you if it workes.

@Aplix said in Why cannot set screenGeometry on imx8 wayland backend: I can not set the screen by screenGeometry . You are not setting the geometry based on screen geometry at all! You set it fixed to 0,0,800,480. Should be: QRect rect = m_desktopWidget->screenGeometry(1); this->setGeometry(rect);

Any solution for this? am getting the same errors

It seems there's a bug reported, regarding this issue. Even though we can build app targeting older SDKs, google play now required all apps to target SDK30 minimum, so that's not a solution.

Everything is identical. One project, one environment. The only difference is in the method of launching Ctrl+R or F5. Where did the $HOME variable come from then in the first case? I would understand if the variable was missing in both cases. Or I switched Release / Debug, but I do not. Thank you!

@Chopper90 Any reason why you're rejecting the answers from the post that you copied from? https://www.reddit.com/r/cpp/comments/9q07bu/any_library_as_small_as_wxwidgets_but_as_powerful/

Open the module .pro file in Qt Creator and build it with the appropriate Qt kit. Then go into the build folder and call make install.

@KroMignon yep I saw this doc but i had problem with including QAndroidService in my cpp code but after adding QT += core-private and using #include <QtCore/private/qandroidextras_p.h> instead of #include <QAndroidService> project start compile

Hi and welcome to devnet, You need to setup your Windows machine for cross-compilation and then cross-compile Qt for your target. Doing it on Linux is usually way easier. Maybe WSL2 may allow you to do that as well.

I should probably add that the StringExtra bit only works if the shared data is small, as it is in my case. If importing bigger files, then I suppose the processViewIntent() would need to copy the file into the apps cache in one way or another, as ekke already said. But the self-restarting bit through firing a new Intent should be applicable in any case.

This approach works on Android 6 and 11 package it.denisgottardello.metronome.metronometouch; public class MetronomeTouchMain extends org.qtproject.qt5.android.bindings.QtActivity { @Override public void onCreate(android.os.Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.getWindow().addFlags(android.view.WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); } } This approach works on Android 6 but not on Android 11 QAndroidJniObject activity = QtAndroid::androidActivity(); if (activity.isValid()) { QAndroidJniObject window = activity.callObjectMethod("getWindow", "()Landroid/view/Window;"); if (window.isValid()) { const int FLAG_KEEP_SCREEN_ON = 128; window.callObjectMethod("addFlags", "(I)V", FLAG_KEEP_SCREEN_ON); } }

@glassez Well, brief is brief. That's what I said. After all, connect returns a boolean result, to tell (briefly) if it has succeeded or failed. Deliberate and consequent ignorance of such results in class constructors is a gamble. If you believe that the reason may be OpenWRT, so be it. I tend to believe in (and briefly summarize) what I see.

I also have the same requirement of several Android applications within one CMake project. @MS_36 May I ask how you overcame this?

Is there any solution to the packaging and use of Android AAR

@JKSH said in degree Celsius symbol not displayed in Qt QML: toLocal8Bit Code is working correctly with toLocal8Bit() on another device with same bsp & h/w. Only one change is on my device I had updated bsp version & then downgrade it (for testing purpose) , In this process some lib/config may be not reset/remove correctly due to this representation problem comes. Now I have change toLocal8Bit() to toUtf8() and now it works on both devices. tr(QString(array[0]).replace("%1",sign+array[2]).toUtf8()); Thanks to all for help

@jsulm Thanks a lot Try 1: Due to there is no 30 in QT 5.12.4: [image: f5fa081d-3420-46e9-882d-3d5ccf01c2ca.png] I tried to add: <uses-sdk android:minSdkVersion="22" android:targetSdkVersion="30"/> so I manually set 30 in AndroidManifest.xml, android 64bit apk is built, but the app can not connect with wifi, and log get this " QNetworkInterface/AF_NETLINK: found unknown interface with index 1 .... If set android:targetSdkVersion="29", has no any issue. Try 2: I update with QT 5.15.6, Android Qt 5.15.6 Clang Multi-Abi, and set this in build.gradle: defaultConfig { resConfig "en" minSdkVersion = 22 targetSdkVersion = 30 } App could be build on usb-connected Android 12 device (Pixel5), but even login can not show up. only show app icon at the top of while background. Would you mind give me some suggestion or hint to solve this? thanks a lot

I check if the Peak hardware is working properly with the peakcan view tool and there I get the correct time stamps.

Logic: 1] maintain the session id 2] get session id which needed 3] add and remove session id on button click

Because proper file are not added so i created new project and linked all file properly that resolve my error
