  When I finished to adjust the version of libc the complete qt gui application didnt start wit a message like couldnt find a platform plugin. I finally downloaded qt-everywhere-src-5.15.0, /media/eric/BPI-ROOT is the micro sdcard containing the os running under bananapi M2 zero with ubuntu Mate which I connected to my development pc with ubuntu 20 64 bits. The command line would look like this? ./configure -release -sysroot /media/eric/BPI-ROOT -opensource -xplatform linux-arm-gnueabihf-g++ -prefix /opt/qt5.15.0-arm should I add some platform options like -eglfs -gui -widgets ? Or the command line should look like this? ./configure -release -opensource -opengl es2 -device linux-generic-g++ -device-option CROSS_COMPILE=/home/eric/gcc-linaro-arm-linux-gnueabihf-4.9-2014.07_linux/bin/arm-linux-gnueabihf- -sysroot /media/eric/BPI-ROOT -prefix /opt/qt5.15.0-arm It exists a specific device for raberry pi but I didnt find for bananapi, I also choosed linux-generic-g++. Should I use the option xplatform instead of device? or using xplatform option instead of device?

  Stupid me. For some reason, the sound is played, but you have to switch to unmute mode to hear it.

  @T-Kloczko Hi! I've faced the same issue, but after I made fixes proposed by you to AndroidManifest, the problem still had not solved. Please, if you managed to start the service from the application, can you post somewhere a minimal working example of the project? Thanks in advance, Kastuś.

  Hello, I am going crazy to find out what the hell my resistive touch screen is not working in EGLFS but works in Xorg. I suppose because the Xorg configuration is going to use evdev and its calibration value in the Xorg.conf section: Section "InputClass" Identifier "calibration" MatchProduct "stmpe-ts" Option "Calibration" "77 4007 3796 107" Option "SwapAxes" "0" Option "InvertX" "true" Option "InvertY" "true" Driver "evdev" EndSection The touchscreen is mounted upside down due to constraints on lcd frame, that's why I inverted X and Y axis. Nevertheless it works great with Qt and Xorg using platform xcb. But is painfully slow. The CPU is a SystemOnChip iMX6 Dual running @ 800Mhz with a LVDS display of 1024x600 pixels. The touchscreen is a resistive touchscreen using driver stmpe-ts over i2c bus and its registered kernel driver is /dev/input/event0. evtest gives me the following data: Input driver version is 1.0.1 Input device ID: bus 0x18 vendor 0x0 product 0x0 version 0x0 Input device name: "stmpe-ts" Supported events: Event type 0 (EV_SYN) Event type 1 (EV_KEY) Event code 330 (BTN_TOUCH) Event type 3 (EV_ABS) Event code 0 (ABS_X) Value 1561 Min 0 Max 4095 Event code 1 (ABS_Y) Value 972 Min 0 Max 4095 Event code 24 (ABS_PRESSURE) Value 0 Min 0 Max 255 Properties: Testing ... (interrupt to exit) Event: time 1593699540.159050, type 3 (EV_ABS), code 0 (ABS_X), value 2807 Event: time 1593699540.159050, type 3 (EV_ABS), code 1 (ABS_Y), value 1834 Event: time 1593699540.159050, type 3 (EV_ABS), code 24 (ABS_PRESSURE), value 54 Event: time 1593699540.159050, type 1 (EV_KEY), code 330 (BTN_TOUCH), value 1 Event: time 1593699540.159050, -------------- SYN_REPORT ------------ Event: time 1593699540.273889, type 3 (EV_ABS), code 24 (ABS_PRESSURE), value 0 Event: time 1593699540.273889, type 1 (EV_KEY), code 330 (BTN_TOUCH), value 0 So it is working for sure (in Xorg it works good). When using ELGFS it does not work at all. I am using a plain vanilla Debian Buster 10 with the official packages from Debian repositories.

Can you help me to workaround this so I can have my touch screen working on the EGLFS platform??? Regards, Gianluca

  @ANNI, you can try to compile the qtconnectivity from the wip/win branch... There are implemented the classic bluetooth for all Windows and the BLE support for the Win8/10 using MinGW or MSVC with the win32 API instead of UWP. But in that case you need to start BLE scanning from the Windows in-box appliction at first, because the Windows does not provided the Win32 API to do the BLE scanning.

  @xixi_cly said in Add log to Qt source code: src/platformsupport/input/libinput/qlibinputhandler.cpp One non-technical comment just in case. You might be already aware that since you're or you'll be modifying a (L)GPL licensed component (see qlibinputhandler.cpp copyright header) you'd be obliged to contribute it back... which might conflict with your application licensing schema... LGPL – Any modification to a Qt component covered by the GNU Lesser General Public License must be contributed back to the community.

  I found that. NotificationManagerCompat and NotificationCompat are deprecated. But i dont know android studio how resolved that.(i used same build tools and target and etc) The corrected code is as follows: package my.package.name; import android.app.PendingIntent; import android.content.Context; import android.content.Intent; import android.app.NotificationChannel; import android.app.NotificationManager; import android.app.Notification; import android.graphics.BitmapFactory; public class GetExtra { NotificationManager notificationManager; Notification.Builder builder; private static final GetExtra singleton = new GetExtra( ); private GetExtra() { } public static GetExtra getInstance( ) { return singleton; } int a=0; public void createNotification(Context ctx, String title, String text, String postid) { int requestCode= (int) System.currentTimeMillis(); Intent notificationIntent = new Intent(ctx, GetNotifExtraService.class); notificationIntent.putExtra("postid", postid); PendingIntent pendingIntent = PendingIntent.getService(ctx, requestCode, notificationIntent,0); notificationManager = (NotificationManager) ctx.getSystemService(Context. NOTIFICATION_SERVICE ); if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) { NotificationChannel channel = new NotificationChannel(ctx.getPackageName(),"new message!", NotificationManager.IMPORTANCE_HIGH); notificationManager.createNotificationChannel(channel); builder = new Notification.Builder(ctx ,channel.getId()); } else { builder = new Notification.Builder(ctx); } builder.setSmallIcon(R.drawable.ic_launcher) .setLargeIcon(BitmapFactory.decodeResource(ctx.getResources(), R.drawable.ic_launcher)) .setContentTitle(title) .setContentText(text) .setDefaults(Notification.DEFAULT_SOUND) .setColor(0xFFFAFC77) .setContentIntent(pendingIntent) .setAutoCancel(true) .setPriority(Notification.PRIORITY_MAX); notificationManager.notify(a,builder.build()); a=a+1; } }

  @GregWilsonLindberg said in Do B2QT programs always have to run as root: We're building a system that runs in a Raspberry Pi3 using B2QT. Is seems to me that applications compiled to run under B2QT are always run as root. Is this true? It is indeed possible to run a B2Qt application as user (not root), but of course the user needs access to required devices, the most fundamental ones being video and input devices. As a small example add your user to the video and input groups: usermod -a -G video,input myuser and then create an appropriate XDG_RUNTIME_DIR: mkdir /run/user/1000 and set the corresponding value in /etc/default/qt. Last, adjust the value of User= parameter in the systemd service (e.g.: /lib/systemd/system/qtlauncher.service). Additional permissions may be required for other features like reproducing audio, etc, but with the above tweaks the application should at least start the B2Qt application as myuser.

  At least with Qt 5.15 you can just create a gradle.properties file in your Android template directory (ANDROID_PACKAGE_SOURCE_DIR). androiddeployqt will merge any properties there with its own.

  I solved this above problem in Qt by using Qandroidjniobject. For launching camera by using intent code is given below, QAndroidJniObject ACTION_IMAGE_CAPTURE = QAndroidJniObject::getStaticObjectField("android/provider/MediaStore", "ACTION_IMAGE_CAPTURE", "Ljava/lang/String;"); QAndroidJniObject intent("android/content/Intent", "(Ljava/lang/String;)V", ACTION_IMAGE_CAPTURE.object<jstring>()); QtAndroid::startActivity(intent.object<jobject>(), 101, this);

  Instead of ANDROID_EXTRA_LIBS, use the android/libs. Copy the .so manually, make sure to keep the proper subdirectory names for architectures. It's the easiest this way - androiddeployqt just copies the whole dir into the APK. You can still use ANDROID_EXTRA_LIBS, but you need to define it separately per architecture in your .pro file - it's a mess.

  Hi, I realise this topic is a bit old but I've just run into this same issue myself, and have discovered a solution for it. So for the sake of anyone else coming across this on Google the mechanism I discovered for providing an API key to the OSM plugin is to set up your own providers repository, that way you can specify the API key as part of the URL template. I made a simple github repo with a script for creating a repository here: https://github.com/Elleo/qt-osm-map-providers And I wrote up a more detailed explanation of everything on my blog here: https://blog.mikeasoft.com/2020/06/22/qt-qml-maps-using-the-osm-plugin-with-api-keys/ Hope that helps, Mike

  @MEMekaniske i personally do not know and also don't think there will be an open source license. But you should ask this rather on the mailing list.
