I think you can specify a local gradle location somewhere, but i haven’t touched that for some years

Yes, this file was downloaded for me. Excuse me, what should I do next?

I'm sorry, is there no way I can fix the problem?? And since my VPN tunnels the entire system, what do you think could be the problem?

C++ & Qt

Gradle version may not be an issue. If it is a problem with download that needs to be fixed.

Also, the Android Gradle Plugin (AGP) version (defined in build.gradle) is compatible with specific minimum gradle wrapper version (defined in gradle-wrapper.properties)

If the gradle files are auto generated by Qt, then they should never be the root cause.

I want to set up Android Kit on Qt I set up the required sdk and ndk but when I build it, it gives a gradle warning because Iran is under sanctions and filtering, I have to use a vpn

Gradle 8.6 seems to be quite old. Is everything up to date?

Processional and Enterprise license will cost even more.

I have not personally used them, but attended regional Qt Meet (Qt Summits organised by Qt sales reps in Bangalore, India) where I have seen the demonstration. Qt for MCU libraries are light weight compared to the Qt for Application Development. Using QML looked super easy for developing embedded GUI. It used standard C++ libraries.

Nope, It is much easier with "Boot to Qt" and "Qt for MCU".

Infact the commercial license "Qt for Device Creation" is the major revenue generator for Qt Company.

Many MedTech and Automotive industries are using Qt for HMI compared to any other frameworks.

I have used C++ for STM32 MCUs and found it straightforward and easy but someone told me that thing about Qt. Not sure how true it is

C++ & Qt

05 June 2026 22:00

Yes, that’s what I mean. Of course it is c++, but you can almost create an app without knowing much of ”normal” c++. The Qt libraries are does almost everything that the .net or java standard libraries do (at least the important stuff) and they integrate with each other as you would expect from a standard library.

It is also very complicated to learn. The license is sometimes hard to pay. There are modules that if you use them, you would have to license your entire project under GPL and look for third-party libraries. It is a mature technology, but there are other options such as Slint.

I’m not sure, but at least the vpn seems to be working

Can you access this file: https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/8.6.0/gradle-8.6.0.pom

C++ & Qt

06 June 2026 15:35

Yes, I think it is a networking problem (either the file isn’t available anymore or the connection is blocked). Gradle wants to download files all the time, so you should look into the vpn setup if you think it may be the cause

C++ & Qt

06 June 2026 15:03

No, I'm using Qt 6.8. I think GRADLE is enough. I think the problem is with the VPN, which can't get the files. Can I set it up manually?

Could you share the build.gradle file?

Most of my prior and current projects use STM32 MCUs for which I use STM32CubeIDE plus C++.
You think Qt for MCU is still a good alternative for them?

Welcome to the group, @Arkenil! :-)

Wanna share your story of how you started with Qt, QML or C++? Maybe some nice feature that made you stick with it.
Rules are set on the description of the group. :)

05 June 2026 22:01

I haven’t really used it, but I think you have to compare it to the alternatives. Embedded can be challenging.

C++ & Qt

05 June 2026 21:59

I heard using Qt for embedded is rather hard, true?

C++ & Qt

05 June 2026 21:49

That’s right, but there’s much stuff starting with Q (eg QString, Qvector and so on) that aren’t identical with standard C++.
Qt is a framework but I guess it doesn’t dislike to look a little like kinda language.

C++ & Qt

Qt is a cross-platform application development framework. It is not a language. It is C++ based. You can also use languages QML (by Qt) and Javascript.

Using Qt, you can build:
- Desktop applications
- Mobile applications
- Hybrid Applications
- Embedded/IoT systems
- Automotive HMIs
- Industrial control systems
