Bundling of a product means that you are forced to buy it even though you don't want it, to get a different product from the same provider that you do want. So your cable provider won't sell you HBO on its own, you have to take 20 other channels you have no interest in. It is not bundling of Android because you can get Google search, GMail, etc. all without Android. There is no other product that Google sells where they force you also to take Android in order to get it. You can make the reverse argument - that Google Search, GMail, etc. are bundled with Android. But that is bundling of GMail, Search, etc, not bundling of Android.
