You can do some tricks with this like have a two-levels cache, the first one with a memory cache and the second one with a disk cache. Already exist libraries that does stuff like this, but how you need your custom tags, you can either modify those libraries or use the cache library in your classes like I show you above. For the AnimationDrawable 's like animation-list you will need build the animation in runtime. For example like this:. If not then download them and add them. Hope this help, but if I was you, I would keep that size, personally isn't so much, I've developed a tumblr client with a lot of animation and ui features, and the apk size was around 15 MiB.

I doubt if your drawable goes this much 20MB here i mean to drawable is xml Files only. Coz these can not be downloaded later , Have you properly optimize your code for Re-useability?

Note: If you are looking for downloadable xml drawables then answer is no it is not possible it must be withing apk and also you can follow the following to optimize. Other that if you still need this functionality you can download it on your application's splash screen and set it runtime as you have suggest using BitmapDrawable. But as per my opinion this is not right way to use this, as when you create your activity that time your view already render on setContentView layoutID.

So when you call your activity it will display the blank views without images. And from other resources i have read that you can not change the resources file like drawable, raw,strings at runtime as it's id's can't create on runtime. You would still have to handle unavailable resources as long as the expansion file has not been downloaded though.
