Now I would like to have as few buttons in the android bar at the bottom as possible but I'm pretty sure both the back and home buttons are required. I believe this is true.
Could I assign the home button to activate the menu button on double click and just have the home and button button? I'm rooted on 5.1.
Alternatively can I make Android activate home and back with volume up and down https://www.quora.com/Can-I-make-an-app-which-tracks-the-Android-volume-control-button-and-does-some-tasks-if-I-long-press-say-volume-up
