If you want to know what it is you can search Google or Wikipedia:
http://en.wikipedia.org/wiki/Dalvik_(software)
As far as installing ROMs go its recommended to clear the davlik cache each time you install a new ROM. On most android phones this is done from within Clockworkmod.

Boot into CWM recovery, it should be under the "wipe". Look for "wipe dalvik-cache" option
Or under the tab: Advanced
Dalvik-cahce
Ive always somewhat wandered what the dalvik cache was never really bothered to look into it. but now i have its nice to know that when i wiped the cache each time i flashed a new ROM it was for good reason. Thanks

It does not mention the cache
Am i wrong to assume it's a bitcode of everything dalvik ever run/saw installed?

Search for what the cache is, read the Dalvik then link them together.

I know what happens when you do a factory reset/wipe, but what exactly happens if I only wipe Dalvik Cache? (I'm about to flash a ROM, don't want to do a complete factory reset/wipe, but wondering if I can still help "eliminate ghosts" by wiping Dalvik Cache.)
Bump, is this just like a crazy question or something?

dalvik is a virtual machine in android operating system that runs applications, which is similar java vm. dalvik builds some sort of cache of applications (i wouldn't go into details) to run them faster in dalvik cache space. you can clear them out, and android will rebuild the cache on the next boot. and the initial boot will take longer than usual once you wiped the dalvik cache because android needs to rebuild it.
So it's something that you can safely wipe on occasion right, just to clear up any bugs?

when you flash a custom rom, usually the rom automatically wipes out dalvik cache to remove all that junk from the previous rom.. you do not need to wipe it regularly unless you flash apps or any other system modifications on top of the existing rom via clockworkmod recovery very often
But is there any "harm" in doing it? Any consequences other than a longer reboot time?

Not at all. Apps will just be a little sluggish for a bit.

Using Kies to goto 2.2, does that wipes Dalvik cache? Koz I went to 2.2 from kies mini, then ODIN'd a Voodoo kernel and i never wiped it manually...
so should I?
many thanks
You are trying to not factory reset but any rom you will find will have a system, data, data_data and cache wipe built into it. You can try finding a Rom you like and remove the wipes from the update_script but those wipes are put there on purpose. Kies will wipe everything too.
or use root explorer go in to system and find dalvik cache and delete files =>
sir can i ask a question?

Yes it is normal for it to take longer than a normal bootup. It is rebuilding the Dalvik that was just wiped. #nosorcery

Thank you for this question, thank you guys now I know that wiping dalvik cache is not that bad at all.
I'm running Adrynalyne's Das BAMF 1.4 with his 4.3a Kernel. I just downloaded the Kernel Manager app and i'm curious if I should first boot into CWM, clear the dalvik cache, then reboot and install the new 4.4.2 Kernel in Kernel Manager or will Kernel Manager give me the option to clear the dalvik/cache when I click "Download & Flash Kernel"?
Any help would be appreciated.
Also, i'm not sure i'm 100% clear on the dalvik cache vs regular cache. I thought I had an understanding, but I want to be sure i'm taking all the right steps when installing new Roms and Kernels.
I see an option in CWM (under Advanced) to "Wipe Dalvik Cache." Is this the only necessary step when installing a new Rom/Kernel? The way i've been doing it is is by doing a factory reset, then clearing Dalvik Cache, then installing Rom, then installing the Kernel.
Are these the right steps? Is there anything else I should be doing?
Thank you XDA, i was only recently introduced to Android and XDA, but I'm starting to learn ADB (manually rooted my phone and have pushed files to SD Card, still learning all the possibilities). This forum is awesome.
ask him yourself. click the link http://forum.xda-developers.com/showpost.php?p=11403269&postcount=7 and then click on web chat towards the bottom. adrynalyne was in the chat.
I was going to ask this same question

Well, after a little Googling, I found that if you click the "Menu" button when you're in Kernel Manager, then click "Advanced Options," you'll be given the option to have Kernel Manager clear both the caches when you flash the new Kernel.
So we should be cool using this approach. Cheers
Dalvik cache is for Google's Dalvik Virtual Machine (their way of implementing a Java-to-bytecode).
Hi.
What is beeing wiped when we apply "Wipe cache" option from recovery menu? So what does "cache" in the recovery menu refers to? Is doing this useful, without firmware update or wipe data-factory reset?
Thanks.

The cache (cache - another useful article; It's basically the same in android) is being wiped . It refers to all those those files created used as cache. It may be useful to free up some memory (usually not too much though).

Thanks. I basically know what the cache is. And I took a look at those articles but I don't think that I need such detailed info about caching. Actually, I wanted to know which cache is being wiped. System cache, disk/memory cache, installed apps' cache etc. ?
up
I think that only files from /cache partition are deleted after wipe

Nope. One of purpose of cache partition is to keep some data when you do update through recovery

I don't know if it'll work for you since you haven't even stated your device . It also seems that you are ahead of yourself at the moment . Read through and learn more before attempting anything or else you may screw up your device.
P.S. - Your question doesn't belong in this thread.

Hi guys,
I have a question regarding installing ZIP files from CWM.
When I am wanting to instal numerous ZIP files do I need to wipe Dalvik cache and reboot my phone in between each one?
This has been my standard procedure but it is very annoying, especially when I have 5 to install in a row!
So can I just install each one straight after the other, then simply wipe dalvik cache and reboot?
Thank you

Yes.
Actually, this is the normal standard
Today I received a msg for the disponibility of an update for BlissPop-v4.0.3-i9300-NIGHTLY-20151008-0524 already installed on my I9300.
How can I flash it?
Thanks in advance
Go to recovery wipe cache & dalvik cache. Install new version. Reboot...
But clean install is best.
