[Interest] Qt (5.5.1) Quick Widgets Example crash EGL_BAD_SURFACE on Android?

Thu Nov 5 19:09:56 CET 2015

I am attempting to evaluate usability of QML and Quick Widget on iOS and Android.

When deploying the Qt Quick Widgets Example debug or release build to an Android Nexus 7 I get the a  crash.

http://doc.qt.io/qt-5/qtquick-quickwidgets-quickwidget-example.html

This last few lines report:

W/libquickwidget.so(29094): (null):0 ((null)): QQmlInspector: No plugin available for view ' QQuickWidget '.
W/linker (29094): libqtquick2plugin.so: unused DT entry: type 0x1d arg 0x4bd
W/Adreno-EGL(29094): <qeglDrvAPI_eglSwapInterval:3971>: EGL_BAD_SURFACE

I see a similar bug report.  I tried a release build and it crashes as well.  Crash when trying to QML-debug QQuickWidget<https://bugreports.qt.io/browse/QTBUG-37382>

I am using Qt 5.5.1 commercial, OS X 10.10.5, with Xcode 7.1

Here is the full Application Output:
