What is Dalvik Cache?

---

What is it? Thanks

http://lmgtfy.com/?q=dalvik+cache

Ok, I searched and found it. But I'm running into a lil problem. I did the apps2sd thing on my 2gig sd card and now in settings, its showing 1gb for the sd card and 1gb total space for the internal storage(which isn't right because the phone doesn't come with that much storage, right?).

What am I doing wrong?

Even after searching on Google it seems that the purpose of Dalvik Cache is very convoluted. From what little I understand it's the location where application data stored by the OS... but I could be wrong.

Simple explanation:

When Android starts up, the DalvikVM looks thru all of your applications (.apk files) and frameworks, and builds a tree of dependencies. It uses this dependency tree to optimize the bytecode for every application and stores it in the Dalvik cache. The applications are then run using the optimized bytecode. This is why when you install a new ROM, sometimes it takes a very long time to boot for the first time. Any time an application (or framework library) changes, it's reoptimized and the cache is updated.

Cyanogen- Thanks! By the way, great job on the rom. I'm running it right now.

So can you tell me why people want to move it to their sd? (By doing the apps2sd, did I already do this?)

Thanks again.

To save memory, of course. And you probably haven't moved your dalvik cache to your SD Card yet.

Ironic

This post is the #2 link in that search... Just found that kind of ironic.

I'm sorry I came off as snide and dismissive -- i guess i was...

I really should have just posted this:
