Installing apps to SHDMicro card instead of memory to speed up performance

Is there any performance benefit in installing your apps to card instead of main memory to speed up performance? The less data in the root system, the quicker the CPU can access everything?
If so there used to be a brilliant cab installer I could dig up that let you pick a location for install everytime you clicked on a cab file in the device.
Anyone know which of the following certainly does -not- work when installed on the card?
1. Changing default.xml to let the Google panel work with Opera instead of PIE.
2. Sktools
3. Pocket mechanic
4. Free regeditor (special arm version)
5. Touch FM Radiofm radio (with rds scrolling)
6. Google maps update 2.3 (google.com/gmm) To enable traffic and streetview
7. Xperia tweak (to change system wide browser to Opera & up the caches)
8. SD Tuneup to boost SD read speeds 8000%
9. That awesome HTC Touch IT screenkeyboard
10. The high definition youtube application.

Actually it's quicker if you install it on the memory as it requires less traffic between the card and the CPU. Only when the memory on the phone is nearly full will there be a real difference in delay.

also fragmentation and other things like it is not really an issue with flash compared to harddisks where filling it too much up can slow stuff down a good deal

MMS image compression

i've searched and searched but haven't been able to find anything regarding this matter. i remember with WinMO, i experienced this same issue...MMS messages compressing images WAYYYY too much for ones that were both sent and received. the quality was absolutely terrible (compression and resolution) and despite having a 300k cap, images would be sent or come in at an average of 35k. after making a registry tweak, images weren't compressed AS much (result would be 120k-150k after compression), resolution was upped to something like 1024x768, and the images looked quite good overall.
what can be done so images look as good in our android builds?
thanks
rob

any ideas?

the running theory is that t-mobile doesn't know what phone we're using so it doesn't know what image size to set the incoming pictures to. it's a network problem. some of the builds that are based off of the nexus one are able to have good quality as long as t-mobile recognizes it.
this is of course if you're running t-mobile. not sure if it's the same with other carriers.

you need a live Linux cd or usb flash drive setup to run Linux, then you mount the /sdcard/android/data.img file and edit the mms settings.
i have a usb flash drive with Linux installed, inserted the microSD card with my android files into my pc's card reader, rebooted my pc and booted from the flash drive into Linux, i then opened a terminal, then typed the following:
don't type anything in brackets []
sudo -s
mkdir ~/folder
ls /media [took note of the SD card in my card reader, in my case /media/Kingston]
mount -o loop,rw /media/Kingston/android/data.img ~/folder
gedit ~/folder/data/com.android.mms/shared_prefs/com.android.mms.customizationBySIM.xml &
then i edited the following lines:
<string name="MMS_Msg_Size3">300K</string>
<string name="MMS_Msg_Size2">200K</string>
<string name="MMS_Msg_Size1">100K</string>
<string name="MMS_Msg_Size_Choose">3</string>
changed to:
<string name="MMS_Msg_Size3">1024K</string>
<string name="MMS_Msg_Size2">600K</string>
<string name="MMS_Msg_Size1">300K</string>
<string name="MMS_Msg_Size_Choose">3</string>
saved the file
type the following in the terminal window:
mount [took note of where data.img was mounted, should be last line]
typed:
umount /dev/loop1 [loop1 was my data.img mount location]
exit
exit
removed the microSD card from the pc and inserted into phone, rebooted into android and now my mms are resized to approximately 720+ KB, instead of 50 KB or less

this is build specific

[Q] Access SD media scan?

Hi all,
I'm making a port of my homebrew for PSP named Musikr. but I'm having some problems while trying to scan the SD Card for songs (Don't know why, when using recursion, always get FC :S). So I thought that maybe I could access to the files Android auto-scans for when inserting an sd. But the thing is that, regardless all the info I've looked for, still don't know how to do that (even if that can be done).
So, does anyone know how to do that?
Thanks in advance

Android stores all the content it finds with the media scanner in the media content provider (basically a collection of sqlite databases/tables).
http://developer.android.com/guide/topics/providers/content-providers.html
For example the music is stored here:
http://developer.android.com/reference/android/provider/MediaStore.Audio.Media.html
You can read that database pretty easily to find all the content/media you need.
You can also register a broadcast receiver for the MediaScanner complete event to notify you if the media scanner has just completed scanning the SD card.
The intent names are:
android.intent.action.MEDIA_SCANNER_STARTED
android.intent.action.MEDIA_SCANNER_FINISHED
android.intent.action.MEDIA_SCANNER_SCAN_FILE
but you have to set the data attribute in the intent-filter in your manifest as well
like so:
<data android:scheme="file" />

[Q] MyTouch 3G (Saphire) 32B with Ginger Yoshi 1.2 Questions

I'm Running Ginger Yoshi 1.2 and I'm still seeing a lot of lag with the dialer/phone (Takes too long to load and most of the time doesn't load the custom ring tone for that contact), also the following games lag and they where not lagging on the stock ROM (1.6 from T-Mobile)
Blow Up (Lite)
Bubble Buster Smileys
Regarding Performance Settings, I have the following questions:
What would be the best setting for CompCahce? I've read that it's recommended for this type of phone, would 26% be OK?
I have JIT Disabled since I've read it still very much unstable and might cause other things to fail, like the screen off/on animations, is this correct?
I have Disabled Surface Dithering, Is it worth enabling it?
I have enabled Allow Purging of assets, I've read that this really helps with the RAM limitation of this phone, is this correct?
I don't have Home or Messaging locked, are they worth locking?
Lastly, I have VM Heap size to 32M, is this the best for my Phone?
I've searched and haven't found anything clear enough for me regarding these questions, if they are answered somewhere just give me the link to the post.
Thank you all for your help and a Huge Thanks for Team Yoshi for there excellent ROM.

I flashed Ginger Yoshi 1.2 recently. I have a question for you. I am unable to get Wifi Tethering working with the same phone. Is it working for you?

I don't use Wifi Tethering
Sorry I don't use it since I don't have a Data Plan...

IMHO, Yoshi works for me, if it is set up correctly. Other than following the instructions in the "quasi-users guide" which really do help (http://forum.xda-developers.com/showthread.php?t=938848), some of these settings have helped for me - I have both 32A and 32B but I use the MT3G 1.2 w/3.5mm jack:
(presuming you have a 4GB SDmicro card [it's good, but higher is better if phone can handle it] and you can boot to a recovery that allows you to partition your SD card - Titanium Backup works if you want to save your apps, but if you want a fresh install, well, here it is):
1. Wipe, re-wipe and if you still are unsure... rewipe some more. Did I mention to wipe EVERYTHING (including battery stats, dalvik-cache, sd-ext... sorry for over-emphasizing this). Then use Ohsaka-Superwipe_v2 and reboot to recovery.
2. Partition SD card. I have a 4GB, so for me 512 MB a2sd space and something decent for secondary space is fine (the rest of my SD is 3.19 GB, so plenty of room).
3. Flash Ginger Yoshi 1.2.zip (works for 32A & 32B... I flashed the version with the 32A radio and IMHO I didn't like it), following whatever settings you choose (installed to partition, Zeam Launcher and 60 MB swap is what I did) then flash auto-boot-2.6.35.12-farmatito -32b-and-a.zip then reboot.
Preset settings right out of boot for my device are the following (I have tried to change the settings and reboot to weird instabilities - app lag, call-to-image lag, no ringer/vibrate, fc issues, etc., but this works for me):
CPU Governor: ONDEMAND
Compcache: DISABLED
JIT: Checked
Surface Dithering: Checked
Purging of Assets: Checked
Lock home/messaging: Unchecked
VM Heap: 48M
On average, I have 33 MB free out of 199 MB and usually the JuiceDefender stuff works to give me a boost most of the time. The phone works pretty zippy for me and reduced the call-to-image lag some folks get when receiving/making a call. Of course results may vary for you, but again, IMHO, it works for me.
Apologies if I am talking to u like if u r a noob or if I am editorializing too much. Force of habit I gotta drink the hell out of. Hope all this helps and take care.

I'll try it
Just a few questions about your recommendations:
1.- I understand that I should wipe
2.- I have a Class 4 8GB SD Card, does the class 4 good enough or should I first get a class 6 or even a class 10?
3.- I will also try these settings
Also, don't worry about talking to me like if I'm a noob, since I am a noob regarding custom ROM, Swap, Paritioning SD, CompCache, etc, etc...

For that type of device, IMO the Class IV is fine, but the Class VI or 10 offer better r/w protections for swap and functionality than a decent Class IV. If you have heavy usage, I would suggest getting something more than Class IV.
Hope this helps and post if the settings have helped you out. Later

Where's my CompCache?
I flashed auto-boot-2.6.35.12-farmatito -32b-and-a.zip and now CompCache is not showing up when I use the "Free" command:
total used free shared buffers
Mem: 112616 107964 4652 0 1492
Swap: 0 0 0
Total: 112616 107964 4652
Before flashing it, it showed numbers in the Swap now it's all 0, I've already tried disabling and re-enabling at didn't work...
Edit: I did a restore of my nandroid backup before farmatito and here is what free shows:
total used free shared buffers
Mem: 112608 100276 12332 0 332
Swap: 29272 14044 15228
Total: 141880 114320 27560

It would appear as if you might not have set the "install 60MB swap on partition" when you did the initial install of GingerYoshi. On my device, it looks like this:
total used free shared buffers
Mem: 203944 198784 5160 0 148
Swap: 60668 37708 22960
Total: 264612 236492 28120
If that isn't the case (not installing the 60MB Swap file), it is a separate issue from the Comp Cache, I believe. Try installing GingerYoshi with the install to partition, ZEAM (or LauncherPro... whichever one you choose), and THEN say YES to the "60MB on partition". You should be fine by then, but if not, let me know.
Thanks and hope it helps.

I hevn't started from scratch yet...
I'm going to get a Class 6 first before creating ext3/4 on the SD Card... In any case I'm a little reluctant on using the 60MB swap since I read too may times that it could affect the life time of the SD Card and that it's not much of an improvement... But as soon as I get a class 6 I'll try and do a clean install with an Ext3/4 with the 60M swap and see how it works.
Right now I have it like this:
Installed with: No Ext, No Swap (because of no Ext) and Zeam Launcher
In Performance I have:
CPU = Ondemand 128-576MHz (altoght I'm using SetCPU for this)
CompCache = 26%
JIT = off (since it messes up the Screen On/Off Animations among other things)
Surface Dithering = Off (I see no reason to have it on)
Allow Purging of assets = On (I see no reason to not have this on)
Lock Home and Messaging = Off (Again No reason to have this on)
VM Heap Size = 32M (seems more stable than 48M)
Edit: In any case, why does installing farmatito make me loose the CompCahche?

In advance, I apologize. It was my belief that I said in advance that I am basing my findings on my 32A device that I physically use.
I forgot to give you the specs that I am running on my 32B device:
SAPPHIRE PVT32B SHIP S-ON G
HBOOT-1.33.0013d (SAPP30000)
CPLD-10
RADIO-2.22.28.25
Oct 21 2009,22:33:27
(Settings below based on a 2GB SDmicro... a size I would not recommend):
EXT, 60MB SWAP and ZEAM
CPU = ONDEMAND with 245 - 528MHz
CompCache = Disabled
JIT = ON
Surface Dithering = ON
Allow Purging of assets = ON
Lock Home and Messaging = Off
VM Heap Size = 48M
I ran the "free" command and I also see the 0 swap size. Hmmmmm... very interesting. I will do some research and look at the bug tracking to see if it is a GingerYoshi thing or if it is something in the way I am installing it on my device as well. As an added piece of advice, the farmatito zip is more beneficial for 32A devices like the 1.2 3.5mm jack device, so if I said to install to your device, you can generally disregard it and see if it gets you better results on the swap.
As an FYI, in terms of screen transitioning, have you checked out the "Spare Parts" included with GingerYoshi? Some of the settings may be for aesthetics or performance in tandem with your space, but perhaps it can free up more memory for the ring-to-display lag you are having. As for apps (Angry Bords, for example), the only one that works with some acceptable lag is the RIO version... blasted ARM processors.
Sorry for the confusion on my part and hope this helps.

I would love to have voice to text anyone know how I can add this to my phone or can yoshi add this to the rom?
Thanks,
Bukethead

Where's my CompCache???
Something changed and now when I run the Free command I get the following:
total used free shared buffers
Mem: 112608 106440 6168 0 2784
-/+ buffers: 103656 8952
Swap: 0 0 0
It has a different layout than before, but mainly under Swap I didn't have only 0:
total used free shared buffers
Mem: 112608 100276 12332 0 332
Swap: 29272 14044 15228
Total: 141880 114320 27560
Can anyone point me in the direction of how to troubleshoot what happened without having to wipe and flash the ROM again?
Thanks.
Edit: I had a backup of my ROM and did have the Swap numbers, So I did a backup of everything via Titanium and restored the Nadroid backup, then I restored apps, then the app data then the system data rebooting step by step and the swap still appeared, so I still have no Idea what broke the compcache but it's back now... If anyone has any idea on what could have changed, please let me know...
total used free shared buffers
Mem: 112608 105768 6840 0 32
Swap: 38280 19288 18992
Total: 150888 125056 25832

I am impressed with this rom I've been running yoshi for a few months now and I have no complaints. good job team yoshi!

[ROOT][MOD] Easily Disable Presidential Alerts

I've seen instructions on how to shut off Presidential Alerts (for U.S. folks) that involve removing your sd card and having to use a computer to change a file. Here's the faster and easier way. Why you'd want to do this? I don't care. But after I did it, my available RAM was up to 1.5/1.6 GB whereas it's typically at 1.2 GB after clearing everything. (No idea if/how this change could affect RAM like that, but that's what I'm seeing in the 20 minutes since doing this mod.)
///ANY PROBLEMS THAT RESULT FROM DOING THIS ARE YOUR OWN FAULT. I'M NOT RESPONSIBLE IF YOU BREAK YOUR PHONE OR MISS OUT ON WARNINGS OF THE APOCALYPSE.///
1. Put phone into Airplane Mode until you've completed ALL steps (if you don't, your changes to the file will be reversed upon reboot).
2. In Root Explorer, go to /data/data/com.android.mms/shared_prefs.
3. Open file com.android.mms_preferences.xml in text editor.
4. Find <boolean name="pref_key_cmas_presidential_alert" value="true" /> (it's near the bottom) and change "true" to "false".
5. Save changes and go back to com.android.mms/shared_prefs folder.
6. Delete the backup file com.android.mms_preferences.xml.bak (this was automatically created when you saved the change to the original file).
7. Reboot phone, open Emergency Alerts in messenger app (Messenger/Settings/Emergency Alerts), and verify that Presidential Alerts is no longer checked.
You can now turn Airplane Mode off and go about your day.

Thanks. Glad to get a bit more ram. Been wondering how to disable that service. Thanks. I got 1.7gb ram from 1.2 or 1.3.
As for why that happen is because thats a service that boots up with the phone. So as it was running it takes the sone resorces cause it did say on it that it is always active. Thanks for shareing this
