Android launch an activity from a broadcast receiver

Question

I know it may not be best practice but this is what i want to do.

When my broadcast receiver is called - start a new activity which has is not fullscreen and has a transparent background - which opens on top of your current activity / desktop wallpaper.

The code I have so far is as follows:

I create + call a new activity with :

  Intent testActivityIntent = new Intent(context, com.andy.tabletsms.work.SMSPopup.class);
                testActivityIntent.putExtra("com.andy.tabletsms.message", main.msgs.get(i));
                testActivityIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                testActivityIntent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
                context.startActivity(testActivityIntent);

And then the activity has a theme of :

android:theme="@android:style/Theme.Translucent.NoTitleBar"

And the code of the activity is just a bog standard activity with a simple layout. However when that broadcast receiver starts the activity - it appears on top of the previous activity which was started when the applicaiton started.....as per this image shows :

This is related to the problem I answered in a previous question here: Activity started from notification opened on top of the activity stack

Basically it's all about: android:taskAffinity and android:launchMode
