[Android-development] [Development] Help needed to test Ministro 10.3, needed for Qt 5.4!

Hi,
Ministro is *NOT* downloading the Qt libs & resources in a temporary folder, nor on SD card! It downloads them into its own private folder (which is a safe place) then it changes the file permissions to 0644 (MODE_WORLD_READABLE), this way any application can read them, but only Ministro can change them.
Cheers,
BogDan.

I don't know for sure, but it is likely related.
Already now with KitKat 4.4.2 I've been unable use local libs deployed
to temporary directory due to various errors.
I've been wondering is it not possible to deploy the Qt libraries to an
app specific directory and then just update the apk in place, rather
than using a temp directory? A related question is that can an app
write its own shared libs? If it can, then I assume for development
purposes that could work so that app copies the libs it uses from some
common area. That might be faster than over the usb deployment.
