Android Bitmap Memory Issue - Error: Out of memory on a 8294416-byte allocation

I am currently developing an app that goes through a story. The story contains "scenes" which contain multiple JPEG and PNG files that are displayed via ImageViews. I create the ImageView and add at it to the layout via the following function:

private ImageView newImage(Show show)
{
    ImageView iv = new ImageView(this);
    String filePath = comin.generateFilePath(show);
    Log.i(TAG, "newImage, filePath = " + filePath + " id = " + show.id);
    WeakReference<Bitmap> bmp = new WeakReference<Bitmap>(scaleBitmap(filePath)); //added 4/1/13
    //Bitmap bmp = scaleBitmap(filePath);
    Log.i(TAG, "newImage, width = " + bmp.get().getWidth() + ", height = " + bmp.get().getHeight());
    iv.setImageBitmap(bmp.get());
    iv.setScaleType(ImageView.ScaleType.FIT_XY);
    iv.setId(show.id);

    //set visibility
    if (show.visible)
        iv.setVisibility(View.VISIBLE);
    else
        iv.setVisibility(View.INVISIBLE);

    //set dimensions
    int width = (app.getWidth() * show.dimX) / 100;
    int height = (app.getHeight() * show.dimY) / 100;
    RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(width, height);
    iv.setLayoutParams(rlp);

    return iv;
}  

Once the scene is over, I then clear all of the ImageViews except for one which has no image and only serves to listen for touch events.

private void clearScene(boolean clearTouch)
{
    RelativeLayout parent = (RelativeLayout) findViewById(R.id.relative_layout);
    logMemory("clearScene, START");

    int count = parent.getChildCount();
    for (int a = count - 1; a >= 0; a--)
    {
        int id = parent.getChildAt(a).getId();
        String message = "clearScene id = " + id + ", count = " + count + ", a = " + a;
        if (id == TOUCH_VIEW_ID && !clearTouch)
        {
            message = message + ", ignore touch screen view";
        }
        else
        {
            unbindView(parent.getChildAt(a));
