Changing LayoutParams of always visible Chat Heads to not always visible

Question

I am attempting to add a view I am generating via a service. The code I am using is based on Facebook Chatheads which are always visible, regardless of the apps state. They

Answer 1

"I now wish to constrain the chat head to the active app."

I see two options. As a simple hack (keeping the Service) use Option 1.
Option 2 means copying BubblesService.java to BubblesLocal.java and BubblesManager.java to BubblesManagerLocal.java, and hacking out all the Service code. I suggest Option 1 is what you want (much easier, and you can turn it on and off).

Option 1

Simply hide the bubbles when your application is not active.
Add the following code to your project (tested, working):

MainActivity.java:

//update ActionBarActivity to AppCompatActivity 
`public class MainActivity extends AppCompatActivity //ActionBarActivity`
private boolean mStarted = false;
 @Override
protected void onCreate(Bundle savedInstanceState) {
...
        initializeBubblesManager();
        mStarted = true;
//------------------------------------------------------------------------------------------------
    @Override
    protected void onResume() 
    {
        Log.i("MainActivity:","onResume");
        super.onResume();
        if(mStarted) bubblesManager.showBubbles();
    }
//------------------------------------------------------------------------------------------------
    @Override
    protected void onPause() 
    {
        Log.i("MainActivity:","onPause");
        super.onPause();
        if(mStarted) bubblesManager.hideBubbles();
    }
//------------------------------------------------------------------------------------------------

BubblesManager.java:

//------------------------------------------------------------------------------------------------
    public void showBubbles()
    {
        if(bounded && bubbleServiceConnection != null)bubblesService.showBubbles();
    }//showBubbles
//------------------------------------------------------------------------------------------------
    public void hideBubbles()
    {
        if(bounded && bubbleServiceConnection != null)bubblesService.hideBubbles();
    }//hideBubbles
//------------------------------------------------------------------------------------------------

BubblesService.java:

//------------------------------------------------------------------------------------------------
    public void showBubbles()
    {
        if(bubbles.size() > 0)
        {
            for (BubbleLayout bubble : bubbles) 
            {
                bubble.showBubble();
            }
        }
    }//showBubbles
//------------------------------------------------------------------------------------------------
    public void hideBubbles()
    {
        if(bubbles.size() > 0)
        {
            for (BubbleLayout bubble : bubbles) 
            {
                bubble.hideBubble();
            }
        }
    }//hideBubbles
//------------------------------------------------------------------------------------------------

BubbleLayout.java:

//------------------------------------------------------------------------------------------------
    public void showBubble()
    {
            //View.GONE This view is invisible, and it doesn't take any space for layout purposes.
            //View.INVISIBLE This view is invisible, but it still takes up space for layout purposes.

        getRootView().setVisibility(View.VISIBLE);
    }//showBubble
//------------------------------------------------------------------------------------------------
    public void hideBubble()
    {
        getRootView().setVisibility(View.INVISIBLE);
    }//hideBubble
//------------------------------------------------------------------------------------------------
