Qt TextField is not invoking the keyboard when launched on Android device
<p>I have simple QML app, that shows only one <code>TextField</code>:</p>

<pre><code>Rectangle {
    color: "#00000000"

    TextField {
        anchors.centerIn: parent
    }
}
</code></pre>

<p>I thought, that Android keyboard will be shown automatically, when I touch on <code>TextField</code>, but it's not happening.
I tried to use <code>focus</code>, <code>Qt.inputMethod.show()</code>, <code>forceActiveFocus()</code> inside <code>Component.onCompleted</code> of <code>TextField</code> and many other methods, but keyboard not shown anyway. 
Tried to use app on other devices and Android 4.1-4.4 versions, but result always the same )))):</p>

<p>Is that a bug or incorrect <code>TextField</code>'s setup?</p>
