I want to force some applications to have floating windows using the (awesome ^^ ) Xposed framework.
So far, I managed to hook on the "onAttachedToWindow()" method (as explained here goo.gl/ZFb8iQ ) to set the floating layout (as explained in goo.gl/GyCXac ), which seems to work pretty well (I can't embed a screenshot due to the forum's restrictions to new members).
However, in order to set a transparent background (outside the resized app, in order to allow the manipulation of other apps in the background), the only method that I'm aware of is adding the following line in the app theme (e.g. styles.xml)
Thanks in advance for your help.
