Happens also with x86 Android build: Cannot find application binary in build dir /.../build-Mind-Android_Qt_6_2_2_Clang_x86-Debug/android-build//libs/armeabi-v7a/libMind_armeabi-v7a.so.

My question is I want to send data and retrieve it in java. for exeomple void ActivityHandler::activityReceiver(int requestCode, int resultCode, const QAndroidJniObject &data) { if (requestCode == REQUEST_CODE) { if (resultCode == RESULT_OK) { const QAndroidJniObject key = QAndroidJniObject::fromString("message"); const QAndroidJniObject message = data.callObjectMethod( "getData", "(Ljava/lang/String;)Ljava/lang/String;", key.object()); if (message.isValid()) emit ActivityHandler::instance()->receiveFromActivityResult(message.toString()); } else { emit ActivityHandler::instance()->receiveFromActivityResult("Rejected!"); } } }

@Dmitriano Probably I had some wrong build configuration, after some experimentation and switching to Java11 it become about 1MB.

@Dmitriano ANDROID_PLATFORM is correct with NDK 21.3.6528147 and NDK 22.1.7171670 but with NDK 23.1.7779620 it is not.

@Dmitriano it is because SDK API 31 was not installed.

@Dmitriano this probably started to work when I updated build.gradle.

@jsulm thank you so much it worked with these code: function: void searchPaths(QVariant path) { QStringList files; // add files to this ( paths ) QStringList filter; // mp4 files filter filter << "*.mp4"; // add filter qInfo("-----"); QDirIterator dir(path.toString(), filter, QDir::Files, QDirIterator::Subdirectories); // get all files in directory while (dir.hasNext()) { qInfo() << dir.next(); files << dir.next(); // } } use: searchPaths("enter path here") now i can sleep easy. thanks

Solved it. The solution was very easy: sudo mkdir /root/Downloads/

@Kuldip-Somwanshi that focus rectangle comes from android directly. As far as I know, you can't change that from Qt/Qml code. Maybe you could disable it with some java code / styles, but I don't know how exactly 🤷‍♂️

@jsulm Thanks for your suggestion. I solved that, as i understand it, the problem is Qt 6.0. In Qt setup folder, android architectures(armv7, v8, x86 etc.) are in directory seperately. But Qt Version 5.14.2 merge all android architectures in one folder. Now, i can create common single kit for all android archs. And it helped to me: https://stackoverflow.com/questions/67291379/unable-to-create-android-kits-using-qt-creator Qt 5.14.2 Qt Creator 4.11.1 Android Sdk 26.1.1 Ndk 21.3.6528147

@jsulm Hmm, it seems it was an Android/Samsung issue... I have rebooted the device, and now calling startService works fine!

did you find a solution?

@KroMignon said in Cannot create new AVD for unknown reason: Okay... Thanks

It has been clearly announced that the 6.0 release would not contain all modules.

@ELEMENTICY Click on "Edit" and take a look at main.cpp. I should have expressed that clearer: How does your code use/start that UI?

@GangsterV said in Error when using checkPermissions: For extra information, I'm using Qt 5.12.3, building on Android arm64-v8a using qmake. One other point, I've forgotten to ask: did you enable Android Extras in your PRO file (QT+= androidextras)?

Solved by: adb kill-server sudo cp ~/Android/Sdk/platform-tools/adb /usr/bin/adb sudo chmod +x /usr/bin/adb adb start-server thanks to this

it seems that i can achieve this through what android developpers call system_overlay i still don't know if i can do it with c++ i found that something like this may exist for QML https://doc.qt.io/qt-5/qml-qtquick-controls2-overlay.html?fbclid=IwAR3aAt6Lj6nVc5drVgLxk9tJ8-jXQS--ZOy2aPsnjoxvqA3L84SfImhVmtM#details

@jsulm That is correct, but I'd first try with the latest Qt 5 version 5.15.2 Regards

Hi, For highly specific platform API, you will have to write some platform specific code. Qt can't cover absolutely everything and it's not its goal. Android is a bit of a special case because of its use of Java. You should take a look at the QtAndroidExtras module and its examples. Note that this is really specific to Android and how it works. There are other extras modules for some often used platform specific stuff that you can take a look at in terms of how things can be done. Note that these modules have been deprecated for Qt 6 in favor of a different approach and integration in a more centralized way.

@Kyeiv , I think yes, because a lot time ago, a mr. Mike Goza tried to add the QtSerialPort support to android (for FTDI, CP, PL and other chips): https://codereview.qt-project.org/c/qt/qtserialport/+/83480 (but unsuccessfull). There are used the USB API, directly. But, you can take the FTDI example provided by @Pablo-J-Rogina , if it will be simpler.

Sorry, I meant for video encoding. In any case, I would separate the streaming and the preview if possible. Generating the network stream for one or more device can be very heavy CPU wise.

@sierdzio Hmm, looks like I did forget that.

@EmileDW See https://doc-snapshots.qt.io/qt6-dev/android.html "Android 6.0 or later (API level 23 or higher)"
