Mobile and Embedded

@dheerendra Ok Sir. I ll check for that.

@Tabanito Probably the best is to have a note during installation or when you start up the application, in case you want to be thorough. The firewall is prevent attacks from outside in your case. Therefore you need to do it on OS level as recommended by @jsulm However, it is also not possible to knowabout outside attacks and their blockage.

Closing this one as QTBUG-70754 is already fixed. Thanks to @AlexBlasche !

@ekkescorner This is not working, "-Wall" will still override those settings.

OK, after many hours try out I finally find out how you can fix it. Download and use Android NDK r10e separately (not install it through SDK Manager) Download and use Android SDK without Android Studio (download android tools from official site) Qt Preferences will installs all needed packages (build tools , platform tools, sdk tools, platform android-28) Install and use Java JDK 8 (not newer) Please note that installing sdk packages through Android Studio will not be detectable by Qt

@sierdzio Actually no , I've just realized that that piece of code wont work without the rest of the library, so Im going to try to realize how is that specific method called, and how it works.

@koahnig thanks for your reply. oh,sorry I am not read that ,when I choose the older NDK version, QtCreator creat the android kit successfully.

Personally (and I have also done this in my own application) I would use a web service that does the communication to the database for you. This ultimately proves to be much easier to set up and the app stores can easily reject the usage of the SQL drivers being used already or at a later date.

Thanks so much for putting me in the right 'path'. haha!! The problem wasn't AVRDude it seems like it was with some other games that I installed for my kids, pesky kids.

The good thing is that Qt for iOS is still static, so I don't have to worry about the Qt dependencies, and for the test client - I've simply replaced it with an XCode based test client (I have to wrap the classes I'm exposing in the framework with Objective-C and Objective-C++ anyhow) and doing my unit tests at that level. I suspect that, as you allude to above, the Qt team moves towards the issues of greatest needs first, and I suspect supporting "embedding custom frameworks into iOS apps" via qmake and Qt Creator is possibly on the list - but not at the top ;). I may tinker with qmake later and try to figure out when/where/how I could accomplish this with scripting during the build lifecycle - if I figure it out I'll update here. Marking solved. Thanks :)

AFAIK, the BPI is very close to the Raspberry Pi, you should take a look at this wiki entry. By the way, why are you trying to build an outdated version of Qt ? The current LTS is the 5.9 series with 5.12 around the corner.

@raven-worx i have been going through android api and discovered that getVolume() was introduced in API 28 its not working because i am using API19 thank you very much

Hi @comarius, glad you found a solution. So please mark this topic as SOLVED with the button "Topic Tools". Thanks!

Thanks @Cleiton-Bueno, I just repeat the steps as you mentioned and it worked this way, I was able to configure it, but I am little bit confused till which step should I stop here! https://wiki.qt.io/RaspberryPi2EGLFS, becasue I did everything and at the end It looks like Qt didn't accept my qmake file Attached below is my configuration log file, I hope if you can find the time to have a look on it, I saw some errors inside but I couldn't resolve the issue, I am still beginner for this staff. https://docs.google.com/document/d/1-Dq9tg9sXo4q6dpIeyYbokvNHbS2wL473GuR4GtP3fU/edit?usp=sharing
