QML App crashes on older Android (version 2.3.4)

JesperWe

I'm using Qt5.2 Beta 1 / QtCreator 3

I have a simple QML only app that I try to deploy on my target device, which is eabiv7a and runs Android 2.3.4 (API 10) so it should be supported. I can successfully deply to my phone, which runs 4.1.2, but the app crashes on invocation on the target device.

I get lots of OpenGL related error messages (Full transcript: http://pastebin.com/tHUJh0yU )

Any possibilities to get around this?

Does your 2.3.4 device fully support OpenGL ES 2? Maybe the driver is missing, as it was not a requirement for droids < 4.0, IIRC.

I don't know, honestly. I guess my assumption was that if Qt Quick supports 2.3 it should run on devices with this OS version or later without any extras.

That depends. QtQuick1 (called QtDeclarative in Qt5) module uses a raster engine, so it should work everywhere. QtQuick 2 requires OpenGL (there is no software rendering fallback here).

But since we're in Beta, it may well be that you have discovered a bug :) I'm not experienced enough with Qt 5 on Android to say for sure.
