Samsung Moment :: Custom Kernel - Partial Audio Buffer And Optimizations
Dec 29, 2009
Don't know if anyone over here cares, but zefie over on SamsungMomentForum.com released a custom kernel with a bunch of fixes. Including a partial audio buffer fix, and a bunch of tweaks and optimizations. Also, persistent root so you can run a bunch of those programs on the market that require it. No WiFi tethering yet, but it is being worked on. Not sure if this includes the battery notification fix because I had already installed CL14 the other day and it's been working for me ever since. This was not difficult to install, once you have the software and drivers required, the update takes less than 30 seconds.
Here's a link:

when i try and download odin downloader it is saved and when i go to open it it says that "windows can not open this file" then it gives 2 options of use web service to find correct program and select a program from a list of installed programs. The file is downloaded as a .rar file if it matters. This also happens when i try to download the newest kernel.

We can now do partial flashes with the CL14 SBL.... If you have not had the CL14 official update yet, you can follow these steps to get it:
Remember... THIS WILL PUT THE CL14 BOOTLOADER ON YOUR PHONE!
What you need:
Sprints Update Utility
1. Create a datatool back-up.
2. Download and install Sprints Update Utility found above.
3. Run the program (now called SWUpdater) and follow all the directions until it says "Flash Downloading Complete".
Once you have the official CL14 update on your phone, or if you already had it, and you would like to flash SDX/Joey's Kernel (and Max's Recovery), follow the steps below.
What you need:
CL14 official update
An SDX/Joey's Kernel
Max's Recovery
1. Create a datatool back-up... (Although you most likely wont need it if you are just flashing a kernel.... But JUST in case, you should create a datatool back-up if you aren't confident that you wont wipe your data!)
2. After downloading and installing Sprints Update Utility, go into the binary folder (C:Program FilesSamsung ElectronicsSWUpgradeModelsBinary) and move the CL14 file to a safe place, MAKE SURE IT IS NO LONGER IN THE BINARY FOLDER.
3. Find the Kernel you want to flash and put it in the binary folder.
Note: Now you should only have one file in the binary folder (the custom kernel). Also make sure that if the file you are putting into the binary folder says 7zip or winrar, extract it!! If you dont you will get the message "Cannot access bin folder!", and you will not be able to start the download.
4. On your desktop there should be a program named SWUpgrade. Run the program and follow all of the steps through the end. After every thing finishes successfully, you will end up with STOCK CL14, this includes the CL14 SBL, along with the custom kernel you put in the binary folder (you are root).
5. Double check that everything worked by going into Settings-About Phone, under BaseBand version you should see S:M900.8.0S.CL14, under Kernel version= 2.6.27 moment(at)momentdev, under Build number= Joey's name (or any other developer who's kernel you put in the binary folder).
6. Repeat steps 1-4, putting Max's recovery in the binary folder instead of the kernel.
7. You're all set.
(If you happen to want to flash one of Zefie's kernels, repeat steps 1-4 also.)
It wasn't a great thing to get the CL14 update before, because it was hard to obtain root. But now with Sprints Update Utility, and all the new kernels, we are able to get root with the CL14 SBL easily.

The following works fine on a G1 but gives an error on the Samsung Galaxy. I was hoping cross-platform support would be better than this. See error below.
private final static int RATE = 44100; private final static int CHANNEL_MODE = AudioFormat.CHANNEL_CONFIGURATION_MONO; private final static int ENCODING = AudioFormat.ENCODING_PCM_16BIT; private AudioRecord recorder_; public boolean open() { int bufferSize = 4 * AudioRecord.getMinBufferSize(RATE, CHANNEL_MODE, ENCODING); recorder_ = new AudioRecord(AudioSource.MIC, RATE, CHANNEL_MODE, ENCODING, bufferSize);
last line gives the following on the Samsung Galaxy phone: 11-14 19:04:07.507: ERROR/AndroidRuntime(7617): java.lang.IllegalArgumentException: Invalid audio buffer size.

where I have got right now on my phone, which is:
1. I updated to stock 2.1 using the sprint update tool.
2. I followed the video tutorial to root the phone
3. then i used joey's page (http://www.joeyconway.com/sdx/custom/index.php) to install the his kernel (joeykrim-SDX-kernel v2.0.4 (includes root)).
I have done nothing else to the phone but this and removing a couple of bloatware apps (i checked the list of permitted deletions before i removed anything.) I have not installed a new recovery..at least i dont think that I did as part of one of the other operations I performed (as an aside, i am not really sure what the custom recovery is or what it is used for, so i didnt install it...i guess i need to read up more...)
So that is where I am..but i have a couple of questions.
1) i am now having issues with my wifi connection - the signal reception is very spotty in areas where i should have atleast 2 bars of reception, and the wifi often cuts out completely....Is there any know corellation between joey's kernel and this wifi issue? I have searched the forums and have found nothing that answers this.
2) Is there an easy way to get back to the stock kernel? I have read that i can get back to stock everything by using the sprint download center where I did my original 2.1 update. But is there a way to get back to just the stock kernel without wiping the phone?

I am working on a packet switched network. I want to capture the audio data from mic into a buffer at a desired sample rate.How can I capture the audio data from mic into a buffer instead of a file? Also how can I control the audio capture rate as per the desired sample rate?

This may be impossible but is there any way that I can get a smaller buffer size for AudioTrack than what is provided by getMinBufferSize method?
This is how I am instantiating AudioTrack right now: SR = 44100; bufSize = AudioTrack.getMinBufferSize(SR, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT); audioTrack = new AudioTrack(AudioManager.STREAM_MUSIC, SR, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, bufSize, AudioTrack.MODE_STREAM);
With sample rate of 44100, getMinBufferSize always returns 4800. If I try to make the buffer size smaller than 4800 then I get the following error message: E/AudioTrack( 318): Invalid buffer size: minFrameCount 1200, frameCount 600 E/AudioTrack-JNI( 318): Error initializing AudioTrack E/AudioTrack-Java( 318): [ android.media.AudioTrack ] Error code -20 when initializing AudioTrack. D/AndroidRuntime( 318): Shutting down VM W/dalvikvm( 318): threadid=3: thread exiting with uncaught exception (group=0x4000fe70) E/AndroidRuntime( 318): Uncaught handler: thread main exiting due to uncaught exception I/CheckinService( 59): From server: Intent { action=android.server.checkin.FOTA_CANCEL } E/AndroidRuntime( 318): java.lang.RuntimeException: Unable to start activity Does anyone has any ideas how to over come this problem?

I am currently trying to create an Android application that loops Audio from the mic to the earpiece, I can do that perfectly but when I do it over and over again in my application I eventually get an Out Of Memory Error.
Here is the code I use to create the Audio Loop:
CODE:.................
And here is the error I get:
CODE:........................
So the Error specifically focuses on this line in the code
CODE:.................
And it happens after I try to do the Loop several times, so say I start the application and after 10 times starting the loop I get the error.
So I think the buffer is simply becomiing full or something?? Is that correct? If so how would I keep clearing out the buffer?

After looking high and low, I cannot for the life of me figure out why I cannot flash Joey's Vernal through the SW Updater. I have followed the instructions like it said at the SDX site, but when I remove the official 2.1 update from the binary folder and add his kernel, I cannot start download in the updater.
When I click start download at the end, It would give me the "Cannot open bin file" error. I've tried numerous times on 2 different computers (Windows XP & Windows 7). I'm lost at this point. Oh and I'm rooted "I think" because I'm able to see SDX at the top of the recovery screen. Just trying to apple this kernel and its driving me insane

I'm writing an App that needs to continuously record audio in memory and email the last 30 seconds of audio when required. Much of the mediarecorder API is designed to store linear audio in files. Could anybody point me towards a way to continuously record audio in memory, using a circular buffer using the SDK?

Any thoughts to when we might see overclocking? How much over clocking can this phone safely have? I know it has to do with a custom kernel but what is the holds back of making it custom?

Does the Source SDX kernel (joey's) require the phone to be rooted prior to installing?
Or, can the SW Updater be used with this kernel on an official (unrooted) 2.1 Moment?
If so, which version of the SW Updater can be used (and where do you get it)?

My application cannot handle the JNIE overhead, as I need to make 2 JNIE calls to the native C/C++ code for every 20msec. So I am trying to use the native media libraries and the realted C/C++ files provided by Android in the folder "//external/srec/audio/test" of the donut build. Ex. AudioHardwareRecord, AudioInRecord etc.. I am implementing all the calls in the native layer.
I am using the sampling rate as 8000 and want to read 160 samples (320 bytes) at a time.
I used the following values to create the AudioRecord..
CODE:..........
It says "success" after creating this interface but I am getting the error "Bad Value" if I am doing the InitCheck.
And it is crashing once I start reading the samples or if I try to retrieve the configured sampling rate.
Has anybody tried to access this native code?

Don't extract the file(s) from the tar that you download, the file that you download is what you need. Load Into the PDA setting in ODIN Flasher!

I've been eyeing the Moment and have toyed around with it and the Hero at the Sprint store. Why is it that people seem to prefer the Hero to the Moment almost 2 to 1? It seems to me that the specs are better, screen is nicer, and the UI can be customized to be as "pretty" as the Hero. Is there something I'm missing?
On a similar note, how is the custom rom community for the Moment? I know there are a number of roms available for the Hero, but I can't even find anything in development for the Moment. I'm not even clear that it can be rooted yet (definitely want to do that so I can install to the SD card).

I have a Plantronics Voyager 510 (LOVE IT!!) and I can only seem to get the phone to send calls through to it. It works perfect, but how can I send audio from the Music Player or from when I am playing a movie? Do I need an App to do it or is there a setting that I am missing somewhere? I am using the Samsung Moment with 2.1

we all know there are problems with stuttering and skipping in Pandora. Here's some proof of what's going on when it happens. I hooked up my phone and grabbed the system log as I started Pandora and easily got it to stutter and skip. I added notes as to what what happening at each step.Perhaps this log will raise some awareness of the problem and if we're lucky all this will make it back to Sprint and Samsung and get fixed soon.

It's time we find out if the audio problems are with all Moment's or just some.If you have used any streaming audio apps such as Pandora, Last.fm or the new Slacker Radio, have you experienced regular stuttering?

I rooted and installed a custom kernal several days ago and am very happy with the battery life. However I have a weird problem ever since. My audio stops working all the sudden out of the blue. Ring, text alert, etc. just stops. the only way I can get it to start again is rebooting. Anyone else having this issue? Can i fix it?

I upgraded from CL14 --> 2.1 DD03 last night. I've noticed the following issue with my Bluetooth / audio routing in my car.
Scenario
* Moment successfully paired to car's Bluetooth after DD03
* I can make/receive calls via Bluetooth -- voice commands with my car's Bluetooth system and call is successfully placed by Moment
* My car has an RCA/AUX jack - I've connected that to my Moment's headphone jack to listen to podcasts while commuting to work.
Here's where the problem starts. If the Moment's headphone jack is connected to my car's AUX input with an RCA cable, I can place calls via Bluetooth (or I can hear the ringing of an incoming call) but when the call is connected (incoming/outgoing) the audio isn't being sent from the Moment to the car's speaker. I know the call is connected because I see the call duration timer on the Moment's dialer screen -- and more importantly, if I remove the cable from the headphone jack the audio is then routed to the car's speaker via Bluetooth. If I plug the cable back into the jack, the audio stops again.
I'm pretty sure that this wasn't a problem in CL14.

1. When my car is off, I need the telephone audio to go out the headphone jack.
2. When my car is on, I need the Moment to make a Bluetooth connection with the car and send the telephone audio to the car.
3. I need to keep the audio cable plugged into the headphone jack 24/7.
It is an extremely long story, so just assume 1, 2, and 3 are true and accept that premise.
If the car is on Bluetooth is active but there is an audio cable plugged into the headphone jack, audio is sent out the cable and NOT via Bluetooth. So when the car is on, I need to trick the Moment into not realizing that there is a audio cable plugged into the headphone jack, so that it will send the audio via Bluetooth to the car.Here's my plan:
Disconnect the audio jack from the Moment.
Wire speaker audio to the audio jack.
Assume I have a PACE SMT kit and am comfortable with dealing with surface mount components.From the physical layout, is this do-able?

Does the moment have the capability to send audio/video to an external display? I have a ton of shows/movies on it and I would like to hook it up to a tv to watch them. I found this ---> T3 TV-Out Video AV Cable For Samsung Moment SPH m900 US - eBay (item 110497826612 end time Mar-23-10 05:09:55 PDT) but it is the only place I've seen it and I'm not sure if it will actually work with the phone. Any one got a clue?

This is driving me nuts. When I get in my car and bluetooth connects to the phone, the phone automatically starts playing music through BT audio. I cant find any way to disable it short of turning off BT and I dont want to do that as I play Slacker through BT. Is there an option Ive missed to disable autoplaying of music?

I just went through the process of compiling a custom ROM and they used a stock kernel. I would like to incorporate a different kernel when I compile and instead of the stock. I know I could compile them separately and have them flash together but I want one zip to flash. Just would like to go through the process to learn.
what I have to do when compiling?'
