How to disable android home button

Question

I need to disable the use of the physical button of the Android device (preferably versions higher than 4.0). With researches I found some solutions such as removing actionbar, leaving the application in "fullscreen". I need to use actionbar. I found a not very good solution, which uses the following tags in the manifest:

<category android:name="android.intent.category.HOME" />                 
<category android:name="android.intent.category.DEFAULT" />               
<category android:name="android.intent.category.MONKEY"/>

With this presents a popup asking what action I want to use, Home Screen of the device or call my application. When selecting my application, a new application instance is created...

In short, I need to block the activation/ use of the device’s home physical button within the application. I can’t remove actionbar, I can’t start a new application instance, and I can’t block the back button (physical back button).

Answer 1

The Android Home button for security reasons was made so it could not be blocked by apps.

Any way you find to do this is basically a Hack that there is no guarantee that will work or that will behave the same way in all versions of Android or even on different devices or that use a custom UI, only with the Android SDK will not have anything that allows you to do this.

The only way to do this without using any gimmick is if your App is a Home Screen, the Home Screen will be the only app that will be able to handle the Home key.
