[Development] Playground request: QML for Android

[Nurmi J-P]

Sorry, it’s been 4 months since I was last time playing with this. It looks like the Qt version is not the issue at all. I’m able to run the example fine with self-built Qt 5.5 and 5.4. The problem seems to be that the project doesn’t build with GCC 4.8 used by the prebuilt Qt 5.4 for Android packages. My self-built Qt were using GCC 4.9.

The build problem is in the QOptional class borrowed from https://codereview.qt-project.org/#/c/92006/. It’s handy and less error-prone than maintaining separate booleans whether properties have been explicitly set. :) Maybe I should try with the one from https://codereview.qt-project.org/#/c/105743/ instead.

It’s just that now that I tested things before publishing the source code, I had to sync some gradle build scripts from the latest qtbase/dev to get the example up and running. I’ll test with older Qt builds and update the README accordingly.

I really wanted to have a navigation drawer & the animating hamburger icon in the hackathon demo, and the only way I was able to get it working was with those custom gradle scripts. This is not a polished product, and there are plenty of silly shortcuts like this. :)
