    You're welcome !

    "Here":http://qt-project.org/wiki/Qt_Multimedia_Backends is the backend grid, it hasn't been updated in a while but AFAIK it's correct

        Do you mean that QCameraViewFinder worked in 5.3.0 and not in 5.3.1 ?

              no, since it was never declared to be properly working on android, yet. as said, 5.4 should officially support it, the alpha release should be tomorrow anyway.

                I've just compiled the latest Qt 5.4 source for Android and tried out the camera example again. No dice. The camera frame shows up, but nothing appears in it. I get this in the console Application Output window:

                  -QML or C++ example?-

                  Nvm, just saw first post again. Well that would be pretty disappointing...

                  I'll wait for the prebuild alpha to try, seems it's delayed again tho.

                    @davidh: just tested the camera example with the 5.4 alpha -> same result as your first post, sadly...

                      So what is the difference between the Widget camera example and the declarative-camera example?

                      I've tried both v5.3 (?) and on a nexus7 the later works fine.

                      Is it a widget vs qml thing? Is there a work around for using the qml code that works in conjunction with a widget based app?
