Disable GotoHome behaviour provided by a mouse middle button click on Android

Question

In a business context (not commercial app), I need to avoid middle button click behaviour, that is to say displaying Home Screen

I spent hours browsing Stackoverflow pages, and the conclusion is often :

• it's not possible, regarding obvious security considerations

My need is a bit different :

• I use a connected mouse, I don't want to override device hardware button.
• my app will only be use in a business context, not publicly.

Details :

• my device is a Samsung Galaxy 3 (Model Number GT-P5210, Android version 4.2.2)
• the mouse is a classical 3-buttons mouse (left-click, mouse wheel, right-click)

I can accept :

• to override OnPause, OnUserLeaveEvents (https://stackoverflow.com/a/32938986/2773267 doesn't work in my case)
• to modify my manifest
• to use a service (watchdog-like), that prevent Home display
• to root the device (last-chance solution):
  • modify /system/usr/keylayout (part of https://stackoverflow.com/a/29311126/2773267 answer)
  • all others solution, excepted those I can't accept :)

I can't accept :

• using service (as in http://www.piwai.info/chatheads-basics/)

Excuse my awful english, I'm french !

Answer 1

Putting this 3 lines to the manifest solved the problem. Firstly it didn't work because I made a mistake on activity name

<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.HOME" />
    <category android:name="android.intent.category.DEFAULT" />
  </intent-filter>

Thanks !

You can build your app as a HOME-screen replacement. In this case, your app IS the HOME-screen, so pressing HOME does nothing.
