Android Override Multitasking-key

I have an older Android App with the old legacy menu button and do not plan to update this at the moment. On newer hardware - Samsung Galaxy S5 - the menu button is removed and rep

Solution 1:

However, is there a way to override the new "Multitasking"-button on the the same way as one can do

Not at the level of an SDK app. A ROM mod or other firmware build could do what it wants with that key.
