A2sd "tricks" your phone into thinking that the partition on your sdcard is part of the phones internal memory. Some time report the internal memory correctly others do not its a bug of sorts. Don't worry you did nothing wrong
[G1 General] l_____l:
I believe that is my issue with the new 8GB class 6 card and how my G1 is now slower than the Tandy 1000 I had, long ago. Performance at max CPU speed is now 60-75% SLOWER than when I had all apps on "internal storage" with 7MB free. My ext2 partition on the 8G card is around 830M. I purchased the "appstosd2" from the market, but I'm guessing the s-l-o-w performance is because I have NOT (yet) put the Dalvik-cache on the card's ext2 partition. After reading: http://android.git.kernel.org/?p=platform/dalvik.git;a=blob_plain;f=docs/dexopt.html;hb=HEAD

...it seems that's most likely the "slowness issue". Like launching an app where parts of it have to come from a different hard drive.

I'll try moving the Dalvik-cache to the sd with the apps, but since I only made an 830M ext2 partition, I'd like to view the SD card within Linux Live CD. Perhaps there I could "resize" it to 1200-1400M. Then again, I'd like to keep the apps that came with the device "Market, Browser, Maps etc" within the device's internal memory, while installing pHaT apps to the ext2 partition, such as iMAP weather, aFile, pacman (with flickering screen on 1.5 builds ö) and really large apps that many ppl UN-install and report "I need more space on my phone".

I'm not too new of a noob, however I am a "super noob" when it comes to Linux. I setup my laptop to dual boot Win XP or SUSE 10, yet I'm lost on the 2nd choice.

Long Live the "Code Warriors" !!
[G1 General] ubernicholi:
I've read that having too big Of an ext2 partition can actually have a negative impact. You really don't need more than 500mb unless you are running debian or ubuntu. Moving the cache would be a good idea, and may help the speed issue. B
[G1 General] l_____l:
Indeed, that's why I wanted to make the ext2 no more than a factor of 3. (256x3). The SanDisk "Ultra" product seems not to be true "class 6", but rather 4. That's why I went with Transcend. They also make a 16G class 6, but $90 instead of $20 for the 8G.

I did the Dalvik to SD, and the device seems a tad faster, but, I have an app that puts the cache to SD in the FAT32 partition (for users with root access) and that is probably an issue. I will UN-install that app, but it's tough to understand as the coder is French, and the GUI is kind of, well, "did it do what I thought in English?" The name of the app on the Market is: Move Cache for Root by Costa Mlkhael. Does seem to work, but with appstosd2, it is not needed and probably hampers the system as it tries to access cache. I sure uninstalling it will allow cache to the ext2, but I will be left with loads of folders on the FAT side with what was left over. (a nightmare to delete)....yes, phone is a lot faster now with dalvik on the sd's ext2 partition. :)

[G1 General] mugafuga:
This thread is convoluted

Ok I guess the real question is with the new standard auto-apps2sd setup in all the new builds, does this "Dalvik-cache" get put onto the sd card when you flash?

Or is this something folks still have to do manually?

:confused:
[G1 General] IIIIkoolaidIIII:
My Dalvik cache is showing on my EXT3 partition on my SD card when I mount it under ubuntu, I'm running CyanogenMod 4.0.2. So I'm assuming it automatically moves the Dalvik cache to the SD card, as I have not done anything to move it myself.
[G1 General] marksyzm:

**** you understand that i got to this thread from google and your post is annoying. it causes infinite search loop.
[G1 General] HahTse:
Funny thing is: everytime my G1 gets "laggy", I found it's a good solution to just wipe the Dalvik-cache and voilá, it's running smoothly again.

Just why is that? I thought it was supposed to make applications run and respond faster?
[G1 General] AndDiSa:
Most likely the effect of feeling the phone faster is not due to clearing the dalvik-cache, but due to rebooting the phone. Do you have swap enabled? If yes, rebooting means cleaning the swap completely and restarting with a fresh free swap again. Until it's messed up again, the phone is speedy :)
[G1 General] lazamazu:
Absolutely!
[G1 General] mjben:
OK, I see that this post is rather old, but I'm going to try this anyway.

I too have had a bad lag problem.

Typical- the phone worked great after flashing it to 2.2. After some time the phone became extremely laggy. I got a tip to wipe the cache and Dalvik. Done. Phone works great again. A week later, phone is super laggy again. Wipe the Dalvik- phone works great again.

It's nothing to do with simply restarting. I do that from time to time anyway, and it doesn't help. I don't know what the "swap" thing is refering to. I'll dig into that anyway though.

So- why would a wipe of the Dalvik cause the phone performance to jump, when the dalvik is what's supposed to keep it running smooth in the first place? Perhaps I just have too many apps for it to keep track of? What's the deal with the Dalvik?
[G1 General] convolution:
I did this and google gave me the link back to this post.

INFINITE LOOP.
[G1 General] Effdee:
dalvik-cache is byte code for the java virtual machine

when a new app is installed the classes.dex is compiled for your phone ( against the framework classes ) and stored in /data/dalvik-cache

tbh you don't need to worry about it, it is all handled automatically
[G1 General] DevilofanAngel:
Thanks to Effdee, AndDiSa, & Cyanogen, I have a better understanding of how the Davlik cache works & it's purpose.
[G1 General] letterman12:
the dalvik cache is basically a prefetch for the program dalvik. Dalvik is a virtual machine based on java that allows you to run apps (anything with a .apk extension) and because theres no JIT (just in time compiler) installed by defult it also optimizes apps for you or at least tries to
[G1 General] zallik:
LMGTFY

The irony is this page is the top result from google. LOL
[G1 General] Ancoor:
Thanks for the Dalvik cache explaination... However, If I understand you right, when you put a new ROM on your device, the Dalvik is rebuilt... Some flash ROM guides tells me to wipe the Dalvik cache and other does not mention it... Is this procedure necessary or is it redundant?

PS. Would be nice if some moderator could clean this otherwise informative but messy thread... DS.
[G1 General] ezterry:
In theory it will re-generate thus not be needed for you to wipe it..

However in practice some invalid information seems to be leaked from the previous rom causing forcequits, stalls, and errors when major changes to a rom is made. (particularly when changes to the dalvik run-time environment are made)

I believe what is happening is that while the dex files are re-generated, the old ones are not deleted, so some of the earlier generated files can have links to some of the old not-yet-regenerated files.. causing problems.

If you do a full wipe its of course redundant .. however since the dex wipe if fast (at least in clockwork a bit harder in ra-recovery).. and if you don't do it you will need to wait for all dex files to re-generate incorrectly, then wipe and generate them correctly.. Its sometimes easier just to wipe and let them install cleanly. (its not duplicating anything.. probably a bit faster as the dex invalidation check also takes time)
[G1 General] Ancoor:
Thanks ezterry! Could I then clean the dalvik through clockwork, and it would be re-generated without needing to re-flash the whole thing? Would that leave my apps and config intact?
[G1 General] ezterry:
I think that is a trick question..

Many times for simular roms (such as updating between versions of ezGingerbread) you can simply wipe dalvik, flash and fix_permissions after boot all will run smoothly. (and keep all the previous settings)

(If you didn't wipe dex on first boot yes reboot to recovey, wipe dalvik-cache and then boot the rom+fix_permissions)

However sometimes if you are going between very diffrent roms (froyo to gingerbread for example) I find the system feels very laggy regardless of what I do until I wipe and install..) restoring data to specific apps manualy or via titanium or simular.
[G1 General] TheIneffable:
I remember wiping it because my cyanogenmod g1 wouldn't boot up. It took an hour of being patient. Then I just gave up, reboot, and wiped the Dalvik cache through Amon-Ra recovery. My phone wasn't stuck on the splash screen no more.
[G1 General] poch_1421:
does the dalvik cache have something to do with reduced battery life? i was adviced to wipe everything except the dalvik cache
[G1 General] wmoore:
I Googled and the first result brought me here :D:D
[G1 General] frankdrey:
And this has been said many times already. The answer is in this thread. Cyanogen explains it nicely.

Ontopic:

I wipe my dalvik-cache every morning and it helps keep my phone speedy. It just takes a few minutes to build up again. So I let it do that while I'm getting up:P

By the end of the day my phone is lagging from all the app data cached up.

I have the following specs:

ROM: froyobylaszlo

Swap 256mb class 4 sd (4gb total)

apps 2 ext: ~2gb

Now that I think about it, it could just be the swap being cleared.

And whenever I install a new ROM i superwipe and wipe one by one everything.

Makes me feel good :D

Sounds like there are so many people asking about this, it should be added to the android faq and terminology. This forum should also have a sticky so people can find a quick and dirty explination of what it is and wha it does and how to clean it, and a link to the wiki would be nice too.

Exactly. I read a bunch of stuff on xda, but all I found was vague answers and a bunch of confused people asking the same question over and over. Then I did a google search and found the answers on wiki. A shame that the answers are easier to find in wiki than it is on xda.

The stickies help prevent the loop of people asking a questions, moderators and users having to read it, people asking the same question, moderators and users having to read it, people asking the .........

If the point of the thread is to provide answers, once an answer is found, it should be put in the sticky so the thread doesn't just keep growing out of control in an infinite loop and wasting everyone's time, especially the moderators, who clearly have a huge job on their hands.

[General Questions and Answers] ouyanghai:
Hello All,

I recently bought my first smartphone here in Beijing. It's a dopod D805; I hope to upload media to it from my Vista-loaded PC.

The problem is Vista doesn't seem to recognize the device. I downloaded Windows Mobile Center (sorry if I've got the name wrong) but it doesn't seem to do anything. The CD that came with the device doesn't work (it keeps telling me to install Flash 8.0, which seems to imply the software on the disc was designed for pre-Vista systems).

Any help would be greatly appreciated.

Update:

The phone seems simply not to work on Vista. I am now dual-booting XP alongside Vista, and have had much more success using XP and Activesync.

A new newbie question:

I cannot copy files (music, PDFs) from my PC's HDD to the phone's drive. Each time I try I am told there is not enough free space on the drive. This is absurd, as there is nothing on the drive other than what came on it, and the files I'm trying to copy are quite small. What gives?

[G1 General] chrisrj28:
Hello there, have you tried reformatting your sd card. And there are different dream.nbh files floating around, you just may have a corrupted one. I would try reformatting first and then if that doesnt work I can send you the .nbh I use. And yes you can downgrade from the OTA, I just did it yesterday. Oh by the way when you downloaded your .nbh did you extract it from the .zip file it came in? Just have to ask
[G1 General] ktamkun:
Yes, I extracted it from the zip file. I use Ubuntu, so I'm rather computer literate :D

I tried many different DREAIMG.nbh files, and none have worked :(

And I reformatted it as FAT32 twice, even, although I really doubt the second formatting

was necessary.
[G1 General] unthinkablehero:
no man, I've done it twice because the update kept freezing my phone. I followed the tutorial from here, and I too was using ubuntu. I put everything on the sdcard after reformatting it, and then went ahead with the process of rooting the phone... it worked the third tim and apps to sd works for me too... just took awhile to get everything to work. wish you the best... good luck man
[G1 General] blackknightavalon:
This is why I don't bother to unroot. :D
[G1 General] chrisrj28:
Hmm well then the only thing I can suggest is using the .nbh I have always used. I have never had a problem with it and just did it yesterday. Here it is for download: http://www.megaupload.com/?d=05N71GON Let me know if that works

[G1 General] chrisrj28:
Yes I guarantee that you can downgrade from Official OTA to RC29. Like I said I did it yesterday morning with no problem. I have used that same .nbh file since I started rooting RC30. Did you try using the one I posted?
