Following this thread,

Re-launch of Activity on Home button, but...only the first time

I'm able to launch multiple versions on my app when I launch it from a file browser, It does not happen from normal icon launch. I have set onCreate to do this.

@override
protected void  onCreate (final Bundle savedInstanceState)
{
    if (!isTaskRoot()) 
    {
        finish ();
        return;
    }
    super.onCreate (savedInstanceState);
}

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="xxx.xxx.xxx"
    xmlns:tools="http://schemas.android.com/tools"
    android:installLocation="auto">
<uses-feature android:name="android.hardware.camera" android:required="false"/>
<uses-feature android:glEsVersion="0x00020000" />

<application
