You cannot listen to the home button press event in Android for obvious reasons. As a user, I wouldn't like that.

However, if you want your activity to be triggered when the home button is pressed (similar to how launcher apps work), you can add an intent filter to that activity:

<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>
