if someone looking for answer following might help, Just add this one line in manifest activity tag

 android:launchMode="singleTop"

i.e.

<activity
        android:name=".Ui.MainActivity"
        android:label="@string/app_name"
        android:launchMode="singleTop"
        android:theme="@style/AppTheme.NoActionBar" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.HOME" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

Unfortunately, the new version of Android prevent us to override the Home button... sorry for that!

However, you can do something when the button is pressed. You need to override onPause()

EDIT: I tried this, and it worked (even though it's really ugly...):

@Override
public void onPause() {
    super.onPause();

    Log.d(TAG, "Pause");
    Intent i = new Intent(MainActivity.this, MainActivity.class);
    startActivity(i);
}

You can try using this line at the activity in the manifest.

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

Using this, when user press the home button the system will ask you if you want to open for one time or always, select always and when user press home button will open the activity with the categoty home declared

Why is category HOME required?

I think you need to be overriding onKeyDown

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if ((keyCode == KeyEvent.KEYCODE_HOME)) {
        //stuff here!                 
        return true;
    }
    return super.onKeyDown(keyCode, event);
}
