Mobile and Embedded

Hi, Thanks guys for the nice comments. It took about 7 weeks of evenings and weekends work, starting with compiling Qt 3D for BB10; a lot of time I spent on searching the web for decent free 3D meshes and doing trigonometry for the enemy movement, as my coses and sines are hit and miss; Really hope Qt 3D will be part of Qt 5.2 and that it will have proper support, it really makes 3D fun to work with. I'd like to see Qt becoming a proper gaming platform; Unity could always extend their framework to do 2D UI and networking, etc and it would be a powerful competitor to Qt.

HI, Yes i have the dll's...but in which folder of the wince i should place them to run the applications...

I had qtactivitydelegate was missing. After deleting my android folder in the project the error went away. I saw the newly generated manifest file had qt5 specific changes: <application android:label="@string/app_name" android:name="org.qtproject.qt5.android.bindings.QtApplication"><activity android:screenOrientation="landscape" android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" android:label="@string/app_name" android:configChanges="orientation|locale|fontScale|keyboard|keyboardHidden|navigation" android:name="org.qtproject.qt5.android.bindings.QtActivity"> So that could be the issue.

thanks bmor, that is good to know ! i have given up on trying to get qt compiling with qtquick (1 & 2) and as a result i also don't have webkit. i might give it another try when i can get opengl running on the box later. i hope you have more luck !

Maybe check adb logcat There you gonna see some error message when the app crashes

thanks for the reply! It seems it does indeed exit, with this error: E/libEGL (32084): eglDestroySurface:445 error 300d (EGL_BAD_SURFACE) I get the same error with a sample QML application (SameGame example from QtCreator). I googled around and can't find much of use about this -- any ideas? All I can find is that it might be a problem with the app not implementing onPause() and onResume() functions properly, but I'm not sure how I might implement those myself.

Can you try this test APK I made? https://mega.co.nz/#!pp8EQCiI!TgGvuE7BL4LaLar9jkwYaivEP04FKO6lrtUS6t6s3d4

D0IT's solution has worked. And yes, oddly enough it does work on the desktop version, but D0IT's corrections need to be made in order for it to work on the embedded version Thanks to both! [quote author="SGaist" date="1375039983"]Hi, To add to D0IT, are you sure it's working correctly on the desktop version ? You should also have that error logged on the console[/quote]

Uninstall + reinstall did the trick. Not very satisfying, but at least it worked.

Thanks Raven for the Reply, I found the solution i was using the default method for Creating Static Library "Click here":http://qt-project.org/wiki/How_to_create_a_library_with_Qt_and_use_it_in_an_application#fcaa56d9b97ba0f5703da2272539579e . Inside widgets.pro @TEMPLATE += lib CONFIG += staticlib@ Inside Runtime.pro @INCLUDEPATH += ../src LIBS += -L ../Runtime -lWidgets@ And it Works fine... :)

Yep, XCB crossed my mind too. That is also defacto vnc practice with raspberry pi (e.g. raspbian + tightvnc). I suppose in the longer run there may be a VNC QPA or a vnc server support for wayland.

Yea this is really simple, @window->setGeometry( QStyle::alignedRect( Qt::LeftToRight, Qt::AlignCenter, window->size(), qApp->desktop()->availableGeometry() ));@ thank you very much.

If this setting is required, you should update the wiki. If you feel a bit uncertain about it, you can add a note that it was required on your system. The android stuff is very fresh in the distribution and the wikis are typically after someone has successfully setup the system. There is always a chance that something important is forgotten.

thans SGalst and prismatic for the replies, i was making a wrong use of qt, i realized that i could use design mode in .ui files i'm a lower level programmer so i dont understand the basic.

You're welcome ! There's no need to apologize :)

Qt works with MESA. But in full software mode, it will probably be slow.

OK. Thanks
