It should be part of the APK. Since it's a project specific library, you should rather put in some place fixed in the build folder rather than on your system. It would simplify development and debugging. For android, the library needs to be part of the package. If it's not detected automatically for you, you'll have to add it by hand. Go in the Project panel to modify the configuration as needed.

No call /mnt/Odroid/build/qt5/qtbase/bin/qmake or wherever your self-built qmake landed.

My problem was some libicu dependencies...for now compilation worked!

I understand your issue with deploying your application with 5.7. However, it would be useful if you can test your application built with 5.7 and even 5.8 Beta against Android 7 to determine whether your problem has been fixed in between.

@DivyaMuthyala this is similar to your problem. http://answers.opencv.org/question/37441/how-to-set-transparent-background-to-grabcut-output-image-in-opencv-c/

@BogDan-Vatra First of all, many thanks for helping me with this, Bogdan! I tried it, and it worked! am really happy now. The only problem left is, that the Activity always starts in fullscreen mode. I tried to use Window and ApplicationWindow as root object for the popup dialog, but no matter which height/width I set via QML, it always opens in fullscreen. Do you know maybe also know how I can accomplish that? My gut feeling is, that I need to modify the AndroidManifest somehow, but I haven't found anything yet. Many thanks!

@tmaniero I'm using the cypress cyttsp5 too, but I can not make it work in my linux. My tslib is not recognizing my touch. Did you use some adicional package to your touch works ?

@Andrei-Pushkin I'm with the same problem. But, My touch is not working in tslib (ts_calibrate or ts_test). If I run the evtest, it works perfectly. Did you use some adicional package in your yocto conf (local.conf) file ?

I solved my problem on QT 4.8 using this: export QWS_MOUSE_PROTO="linuxinput:/dev/input/touchscreen0" I used "linuxinput" instead of "tslib". If you execute "ts_test", the touch works?

Thanks for sharing the solution.

@shav thanks, yes that works! Although am quite concerned about the size of the resulting app. Will see. The shared lib gets called and socket instance is created but the QWebsocket slots like onConnected, onTextReceived etc don't get called! If you know a good sample or any more info on how to do this, that would be great.

Hi and welcome to devnet, You can bring your questions to the interest mailing list. You'll find there Qt developers/maintainers.

I see. what if my current embedded Linux software blocks use C source codes, is it still advisable to use QtQuick for my GUI development? or better to use QtWidget for my GUI development? I'm a little confused as to how to combine my embedded Linux board source codes with that of Qt GUI source codes. Do you've any advice as how I may integrate these two together? Do I actually put my embedded source codes into Qt GUI source codes as well?

@Matteo-Vigni One way is to limit the screen orientation mask for the window you are rendering. Screen Orientation Typically, you would OR these enumerations together to specify supported orientations. In your app, when you create the window, set this to the desired orientation and do not provide any others by ORing them together. That should force the window to only allow one orientation when rendered. The example I found which helped me is here: From Window example project

If I understood you correctly then you need to use ABI. I have worked with ABI some time ago and it is quite cumbersome.

Little update, I just compared a .qpf2 (from the internet) which works with my application and a self generated .qpf2 file with makeqpf -dump filename and it seems that my own file does not have any data in Block 1 and 2, compared to the internet .qpf2 file. Not sure if that makes sense... but I kinda suspect a makeqpf tool failure? Again, I'm new to this, I might just talk alot uf nonsense EDIT: Block 0 and 1, not 1 and 2
