Showing Android keyboard from QML TextField

[MarkoSan]

Hi to all!

Inside my Qt/QML app, based on Qt 5.5.1 Opensource Edition, which is being ported from 64bit Ubuntu 14.04 LTS to Android I have QML TextField entity. Now, when the user selects it using toucscreen on Samsung Tab 3 10.1, the Android virtual keyboard should pop up, but it does not.
Is it possible to popup android virtual keyboard using Qt Opensource edition at all or is it possible to pop up Qt virtual keyboard only and therefore I need Qt payed edition? If the first option is possible, then here is my sample code:

TextField
{
    width: 384
    height: 128
 
    placeholderText: qsTr("Android keyboard test")
 
    focus: true
 
    onTextChanged:
    {
        print("Text changed");
    }   // onTextChanged
}   // TextField

TextField
{
    width: 384
    height: 128

    placeholderText: qsTr("Android keyboard test")

    focus: true

    onTextChanged:
    {
        print("Text changed");
    }   // onTextChanged
}   // TextField

To copy to clipboard, switch view to plain text mode
