Ok, I got it. There was a problem on write permission about the location on where saving the photo taken by camera. On some devices, everything goes well, on others the camera will fails to write on disk and instead of given an error, it will freeze the app :-( My mistake, because I used an hard-coded path and I didn't notice it :-(

Hi and welcome to devnet, Boot2Qt being a commercial product you should contact Digia directly about that matter

Now i have found the following method: create your own AndroidManifest file in the deployment setting of your project then add to the project .pro file: @ android { addon.files = example.txt exampledir addon.path = $$[PWD]/assets INSTALLS += addon } @ run qmake, build and deploy your project Regards l.f.

You're welcome ! Don't be afraid to ask question :) Since you have it working now, please update the thread title prepending [solved] so other forum users may know a solution has been found :)

Does Qt 5.3.1 widget apps work with Android? Should roll-back to Qt 5.2.1? The messages following the exception refer to QtActivity. Is that a useful clue or just means it crashed shortly after starting? -Ed

Hi, Have you confirmed that your beaglebone image includes the GLES2/gl2.h file? If so, check your QMAKE_INCDIR_OPENGL path, perhaps your missing the final directory? Similar to this (for another embedded) @QMAKE_INCDIR_EGL = $${QMAKE_PATH}/usr/include/EGL QMAKE_LIBDIR_EGL = $${QMAKE_PATH}/usr/lib QMAKE_INCDIR_OPENGL_ES2 = $${QMAKE_PATH}/usr/include/GLES2 QMAKE_LIBDIR_OPENGL_ES2 = $${QMAKE_PATH}/cubie-rootfs/usr/lib@

Seems solved by disabling glibc, taken from this bug report "bug":https://bugzilla.redhat.com/show_bug.cgi?id=579838

Thank you TRudolph, that is exactly what I was looking for. Apparently my search requests didn't contain the right words. Regards, Greg

[quote author="SGaist" date="1405668675"]Hi, Doesn't Navit use GTK+/SDL for it's UI ? You should rather ask this question on their forum[/quote] Hi, Thanks for the reply. I think by default Navit is using "internal gui". I got this from navit.xml, "<gui type="internal" enabled="yes">". I found a link "here":http://wiki.navit-project.org/index.php/QML_GUI, and they are using "qml gui" instead of internal gui. I tried this, but i doesn't work for me. May be i will try in their forum to. Regards Ansif

Solved. It appeared I had a 64-bit NDK installed even though I thought I had downloaded a 32-bit NDK. I blew away all NDK remnants and downloaded new 32-bit r10 NDK and now my Android x86 emulator is launching my Qt hello world app. android-ndk32-r10-darwin-x86.tar.bz2 -Ed

That doesn't answer my question, what kind of gif is it ? What are the image characteristics ? A 60M file looks like a very big animated gif so it might not be the best format for such an animation. QMovie caches each frame of your gif in a format suitable for displaying. If you think it's not optimum you are welcome to improve the class.

Found it. "Input on linuxfb":http://qt-project.org/doc/qt-5/embedded-linux.html#configuring-for-a-specific-device

The solution for you problem is here: "http://www.qtcentre.org/threads/57352-QScroller-speed-and-touch-screen?p=265102#post265102":http://www.qtcentre.org/threads/57352-QScroller-speed-and-touch-screen?p=265102#post265102 Take a look in my post there. My QScroller is working fine now! Here is the Qt Code in case the link breaks: Try setting the verticalScrollMode of your view to ScrollPerPixel> @setHorizontalScrollMode(QAbstractItemView::ScrollPerPixel);@

ok I found the solution: in "build settings" from Xcode project in "Apple LLVM 5.1 - language - C++" section in "C++ standard library" line add "libc++" option thank's

I use bluetooth on Android, arm and i386 architectures without any problem. Bluetooth in not so easy to explain. I suggest you to look at the examples in Qt example subfolder. There are many steps, first pairing, second connect, third send and receive data...
