Android - Application doesn't restart after being sent to the background and recommended fixes aren't working

I'm using TItanium SDK 3.1.3 and my project is made in Alloy 1.0, the problem I'm experiencing has been reported in the past but even when I try to use the recommended fixes for it, it just won't work.

I've seen this, this and this tickets, so far both solutions, using the property

<property name="ti.android.root.reappears.restart" type="bool">true</property>

and the property

android:alwaysRetainTaskState="true"

on my tiapp.xml doesn't seem to work at all.

This is my tiapp.xml:

What are my options in this matter? Is there a workaround for an Alloy project?
