Android resource loading

Does android all deflate images in the apk when it first runs?

For example, I have different .pngs in a drawable directory. When does android deflate images and load them in memory?

Does it only do it when I execute the code like:

imageView.setImageResource(R.drawable.myimage)

Yes, that's exactly when they get "deflated", whenever you reference an drawable resource from R.java.
