Glad you found out and thanks for sharing !

In my case, I think use that function is an easy case to get notification. You can try it if it fit your requirements

I think I know why(guess), although my phone support camera2, but sony disable the api, please check this post for more details.

Hi and welcome to devnet, Either update Qt to a more recent version e.g. Qt 5.12 or downgrade your NDK to r10. More information in the Android Getting Started guide in Qt's documentation.

I downgraded to qt 5.13.2, and it is working.

It's possible this is a bug, seems that the pixel data alignment is broken for some reason. Could you prepare a very simple self-contained project (along with the test image) and upload it somewhere? Please strip the irrelevant code if you decide to do so (like the m_ptnImageCache).

The output about XDG_RUNTIME_DIR is just to let you know that because the XDG_RUNTIME_DIR environment variable was not set, Qt selected one for you. It's essential e.g. for running wayland, but generally the Qt's default is suitable. With the commercial Qt Creator, we use the appcontroller to make sure that only one GUI application is running at a time on the device. Since you are running on open source version, you need to do this manually. Running multiple GUI application at the same time may result in undefined behaviour, since both apps fight for the same screen.

@zamek Hi, I'm facing the same issue. Can u please elaborate a bit more about your suggestion as i'm not able to understand what you want to suggest. Thanks in advance

Perhaps the mkspecs is broken, they are never fully tested (way too many combinations!). Luckily, you can modify mkspecs by hand. Browse the mkspecs directory see if you can find qplatformdefs.h there, if it's missing or in a wrong place you can move it about, or copy the file from other platform and adapt it to your needs.

@paul_espinosa thanks ,, worked for me also installing Qt-5.7.1 on armhf

@Hai-Long-Tran, this absolutely worked for me. Kubuntu 18.04 LTS

@jsulm said in Are results of Qt Creator (ex. .UI file) also under GPL?: @St-Pio said in Are results of Qt Creator (ex. .UI file) also under GPL?: LGPL and dynamic linking style, I don't have to open my whole code, right? right Same for LGPLv3 with the exception that you have to provide object files (not source code!) to your users, so they can relink your app with their own Qt libs. AFAIK, providing objects is only needed when doing static linking. When using dynamic linking, you can just swap libraries as you wish.

To build sqlcipher for android you can see my branch for sqlcipher in https://github.com/sjemens/sqlcipher/tree/android There are instructions in the readme. For the iOS I have not ever tried it but there is a fork of my repo in https://github.com/tr1cks/qsqlcipher-qt5 but I am afraid I can not help much further here.

Hi, The one which is downloaded using qt unified installer doesn't have open source version. I found the place where one can install the open source version here https://download.qt.io/archive/qt/5.14/5.14.0/ This is helpful for someone who is trying to find the open source version just like me Thanks Sachin

No idea?

(This doesn't sound like it has anything to do with mobile or embedded systems)

I'd say your source image is nul because of :. Use double backslash ot forward slash.
