Minimal Android version to run QT5.1 apps?

Huk256

Hello.

I would like to ask: what is the minimal Android version to run applications build with QT 5.1 ? I tried running simple QML examples (Maroon QML example game) on my HTC Wildfire S (Android 2.3.5), and no matter what options I tried, it always crashed. On the other hand - it works (although without sound effects), on my Android 4.0 tablet.

Is QT targeting only Android 4.x and not the older versions? As I recall older QT4 Necessitas worked on my Wildfire S...

Thanks in advance for the answers.

Best regards.

The Qt 5.1 for android is buildet with Android's API Level = 9. Thus, theoretically you can launch it on Android 2.3.x. (if I am not mistaken).

But a problem that Qt5.1's libraries is compiled for the ARMv7 processor, but the majority of old devices is used by ARMv6. Therefore you receive an crash on 2.3.5 device.

IMHO.

I see, but is it possible to compile required qt libraries during application compilation and upload them to the device?

You could try to build Qt5 for armeabi and not armeabi-v7a

You can find some information in here:

Do Qt 5.4 apps work on Android 2.3? Mine certainly does not, my app comes up with a blank screen (but works on Android 4.4). I don't think the problem is about armeabi, since simpler test apps mostly work (with armeabi-v7a). Problems are reported in QTBUG-41755.

Has anyone tested Qt 5.4 apps on Android 2.3?

The problem I had was fixed in the final version of Qt 5.4, my app now runs on Android 2.3.

Hello.
I test QML app build for Android. I success compile and run my app on Nexus7 (armv7) and virtual android device.
Now i try compile this app for my HTC Wildfire S (armv6).
I clone auto-detected kit for android armeabi-v7a.
In projects -> Build & Run add new Kit and in "Build Steps - Build Android APK" select Android build SDK = anroid-10.

Now, when I build my app, I have error message in "Compile Output":

...
BUILD FAILED
/home/user/projects/android/android-sdk-linux/tools/ant/build.xml:653: The following error occurred while executing this line:

Error while building/deploying project positioning (kit: Android for armeabi armv6 (GCC 4.9, Qt 5.4.0))
When executing step "Build Android APK"

Can you help me?
How can I compile the app for armv6 (for run it on HTC Wildfire S).

Thanks for your reply.
