How to remove my app from - history apps (that was launched)

Question

how can I remove my app from the history app (history - by long press the home button)

I look and done some things I saw, but it doesnt work, and I still see my app in the history.

I call to finish()

onDestroy(){
        super.onDestroy();
        int id= android.os.Process.myPid();
        android.os.Process.killProcess(id);
}

in manifest i wrote:

<application
    ...
    android:persistent="true"
    android:noHistory="true"

     <activity
        ...
        android:name="com.example.android.activityrecognition.MainActivity"
        android:configChanges="keyboardHidden|screenSize"
        android:launchMode="singleInstance"

You can implement this from your AndroidManifest.xml file, just adding android:noHistory="true" attribute in those <activity> you want.
