I may not have a Nexus S, but this thread is quite hilarious haha.

Psh. If only the Droid OG or Droid X had lag fixes haha.
[Nexus S Android Development] Luxferro:
Droid OG lag fix = buy new phone

That's what I did. My Droid OG now sits in a drawer. Nexus S is 1000x better in just plain old usability (browsing, games, ect) w/ no lag :p

HI, supercurio,

May I know how to restore the original setting?

Since I read about the Voodoo Lag fix may cause BT problem,

I want the way for recovery setting just in case.

ext4 performance

why not disable barrier?

mount -o remount,barrier=0 xxx xxx

I use this option and it over 9000 !!! :)
[Nexus S Android Development] DebauchedSloth:
There are a number of options that might be of use here, and that's one of them.

Disabling barriers, disabling journals (or changing journal writeback modes), etc.

Many of them are unsafe if you don't know what you are doing, like disabling barriers. They can also be quite fast and reduce wear on flash...

I switched mine to noatime. IMO, that's worth doing for sure. I've been doing this for years on my laptops and haven't run into anything that cares about atime. Relatime is an improvement, but noatime is better still.
[Nexus S Android Development] morfic:
as root:

mount -o remount,noauto_da_alloc /data /data

before:

/dev/block/platform/s3c-sdhci.0/by-name/userdata /data ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered 0 0

after:

/dev/block/platform/s3c-sdhci.0/by-name/userdata /data ext4 rw,relatime,barrier=1,data=ordered,noauto_da_alloc 0 0

so:

mount -o remount,noauto_da_alloc,nosuid,nodev,noatime,nodiratime /data /data

gets you:

/dev/block/platform/s3c-sdhci.0/by-name/userdata /data ext4 rw,nosuid,nodev,noatime,nodiratime,barrier=1,data=ordered,noauto_da_alloc 0 0

not that i could benchmark this with quadrant not running on nexus s yet

might have to drop money on the advanced or so

(yes i snuck in nodiratime, out of habit)
[Nexus S Android Development] krohnjw:
In case anyone is interested in some quadrant results I ran a custom benchmark with no 2D/3D as this is where it constantly crashes (so just CPU, MEM and IO) to compare the remount options above:

https://spreadsheets.google.com/ccc...1BUMnNMOE5ELTcwM0NZamc&hl=en&authkey=CO_Js4YL

tldr; No visible gains in IO from mount -o remount,noauto_da_alloc,nosuid,nodev,noatime,nodiratime /data /data over mount -o remount,noauto_da_alloc /data /data

atime and diratime CAN have a drastic influence depending on the amount of files you have.

Try populating your /data with ~1 Gb of random, small file data and you'll see the difference.

I'm interested in increasing my performance on my Nexus S, but this stuff is a bit beyond my knowledge

It seems a bit over my head, but would anyone be willing to take the time to post a more "layman's" walkthrough of this ext4 business? I would really appreciate it.

[Nexus S Android Development] shrooms90:
Hy supercurio,

Just wanted to know, would it be a problem to mount system and data with realtime instead of noatime?
[Nexus S Android Development] morfic:
why do you want relatime? (note that it's not realtime)

from "man mount"

changing accesstime usually comes at great penalty on slow disk devices.
[Nexus S Android Development] supercurio:
In general, relatime is fine as it updates atimes only when needed.

atime is still a POSIX requirement.

But I doubt Android uses atime anyway. If somebody know, input welcome ;)

My droid 2 is rooted and bootstrapped. I sbf'd to stock then updated to 2.3 then rerooted. No wipe no clear cache. Contacts ok, phone works fine. Just ran bootstrap again as I am getting ready for custom rom install. When I hit REBOOT RECOVERY and navigated around I noticed my system is apparently not mounted. It says mount system. Should I mount system now or leave it alone? I do not understand what exactly I am doing by mounting system. Please advise.
[Droid 2 General] miketoasty:
Mounting basically gives bootstrap the ability to change, delete, or alter anything in the system folder. This must be done to install custom roms.
[Droid 2 General] lizard1:
I must mount system before I install zip from sd, or is this typically done after installation? I'm still reading and trying to take all this in and put it together into a cohesive process in my mind before I proceed. I've come this far w/o bricking(he knocks on wood).
[Droid 2 General] braway:
it depends,

if the update zip is written correctly you don't need to mount system.

for example all Fission update-zips since 2.3 mount system themselves so you don't have to worry.

if you are unsure, you should always mount system.

java compilation on android device

I'm looking to do likewise for various reasons.

One is I live in a tent and the droid device consumes less power than my laptop.

Two is that I'm developing a platform that moves some 'programmer space' activities to user space. Though with java the later can normally be accomplished wo authoring any source or compiling by using introspection and object serialisation (granted an android based dx is needed here) there are use levels of the platform that afford source authoring and compilation.

Having said that as far as I can tell a javac for android is in order.

Thus: openjdk.java.net/groups/compiler/README.html

One needs to verify the source's class dependencies and see if the android vm (the dalvik vm really) implements those classes. If and where not either the compiler code needs to be modified to use dalvik implemented java classes or the dalvik vm extended to accommodate the additional classes, again if any, that the javac source uses.

The determination as to which direction to take need consider the effort involved

either way and the legalities of either way while noting that the dalvik vm is allready the subject of a lawsuit (see Controversy at en.m.wikipedia.org/wiki/Dalvik_(software) ).

Personnaly I'm leaning to modify the javac source if necessary as this

openjdk.java.net/legal/

doesn't look prohibitive in so long, I think, as the language specs are met or more simply.in so long as the modified to run on android javac produces the same results as the original.

If you're ready to get yor hands dirty (not all coding is drag and drop) here ya go

download.java.net/openjdk/jdk6/

Maybe we'll meet somewhere along the way.

[XPERIA X10 Q&A, Help & Troubleshooting] spaesani:
I got ClassCycle and ran it on the classes that resulted from me compiling the javac sources

in the openjdk's langtools directory . These sources are a programatic interface to javac and

are said to be used at one's own risk.I had trouble compiling the 'actual' sources

but will try again.

Once I can make heads or tails of the ClassCycle report I can provide a list

of javac's class deps.

Why one might ask would is any of this class deps stuff needed?

Dx the Java bytecod+e and run it. Droid has a vm, should be ok.

The problem is that Dalvik, at least does not implment awt and swing. What this means is that there is no native implementation for those classes' bytecode to be runtime instantiated towards.

Likewise if there are javac class deps that the dalvik vm does not implement there will be no native implementation in those areas and the bytecode won't run.

Till I get the list,

Script Layer for Android

For rooted systems there is a way to run Ubuntu in the phone/tablet. I don't remember the details, just google for it. I only remember that you should use a VNC viewer to connect to the xserver running in your own system.

I don't know if you can access from that Ubuntu to the resources of your Android (sensors, GPS, camera, and so on).

If you want to be able to create small programs in an easy way for your Android and being able to access all sensors and peripherals of your phone you should consider using SL4A (Script Layer for Android).

It's a base scripting system. On top of it you can install Python, PHP, Bash. So you can write your own scripts using any text editor in the phone, and run it without using any computer in the process

Hi guys,

Just wanted to share an app which is awesome with you if you haven't yet tried it. It's called Windows phone android and can be found in the market, basically it's a wp7 themed launcher. Here are some screens:

As you can see you can change the background with a white/black choice, and also the tiles which is a red/green/blue/orange choice.

Big credit to the dev, give it a try, makes my hero look so much better.

Extra point - The apps recommended resolution is 800 by 480 but it works perfectly on my phone running Floyo 1.2.0.

Run smooth?

I mean really? Not smooth enough. . . .

1.No robot voice(I never had this issue myself)

2.Not kill your battery in half the time of WinMo

3.Not lock up the phone after you get off a call for a few seconds or if you are trying to pick up the call

4.Actually alert you when there is a 2nd call coming in when you are on the 1st

If you have a Build that can do all the above and stay that way for a extended period of time I would love to hear it.

I have tried I think every combo out there. Some do better then others, but can't do all of what I mentioned above.

I am not a developer so I can not correct these issues. I am barely starting to understand programing.

Until then I am forced back to WinMo. I love the Robot, it is totally better then WinMo 6.5 or even 7. . .

But, I need stability in my phone's OS, I use my phone all day.

WinMob ROM: Energy's full-fat (Cookie etc.) with 3-second boot auto-enabled

(Will look up Radio etc. if needed)

Network: O2, I'm based in London

1.No robot voice(I never had this issue myself)

--- No (well, once in a month of operation)

2.Not kill your battery in half the time of WinMo

--- I was getting 15 hours, 5ma on stand-by. With an extended battery I am around 36 hours. Using Live Wallpapers, constant data usage.

3.Not lock up the phone after you get off a call for a few seconds or if you are trying to pick up the call

--- Never experienced

4.Actually alert you when there is a 2nd call coming in when you are on the 1st

--- can't answer this*. Not had this happen yet.

5. No other issues, fine camera, no lock-ups, smooth, no data-drops, no wi-fi issues, no Exchange issues, all Apps fine etc. GPS takes longer to lock on than WinMob (maybe a minute), but I think that's quite common. Almost all feedback in the thread is positive.

you're going to get a lot of answers for this, the main successful thing I have found is to run a task29 and THEN flashing a winmo ROM. This seems to clean things up and Android runs very well after that.

After a call my phone never hangs (I didn't even know people were having this issue) and my phone always tells me there's another call when I'm already in one (again, I didn't even know this was an issue to some).

The main success I've had is running task29 then flashing NRG ROM, if you don't run task29 you can have weird things like high battery drain going on.
