Necessitas alpha 4, a New Hope!

[Mohan_qt_developer]

Hello Group.

When I try to deploy application on andriod tablet, initallly I got Can’t 
find Ministro service, the application can’t start . But after solving this 
problem(by installing ministro || apk), I am encountering with Invalid Qt 
version error on android tablet.

FYI: I have used linux-online-necessitas-alpha4.1-sdk-installer 

Someone please help me.
