I've been I'm this forum long enough to know a lot about flashing and stuff but ppl have been saying stuff like 1.4 kernal or 1.2 and I have no idea what kernal is and what it does.. and I couldn't find any topic on it... so can anyone tell me what it is and what it does

This is my understanding but I may be wrong or over simplifying. The rom is your house, modem is your phone line/tv/internet, your kernel is the circuit breaker.
It controls the filing system and power allowances, I believe. Once again someone may read this and mock me

That sounds about right
From Wikipedia, the free encyclopedia
Jump to: navigation, search
A kernel connects the application software to the hardware of a computer.
In computing, the kernel is the central component of most computer operating systems; it is a bridge between applications and the actual data processing done at the hardware level. The kernel's responsibilities include managing the system's resources (the communication between hardware and software components).[1] Usually as a basic component of an operating system, a kernel can provide the lowest-level abstraction layer for the resources (especially processors and I/O devices) that application software must control to perform its function. It typically makes these facilities available to application processes through inter-process communication mechanisms and system calls.
Operating system tasks are done differently by different kernels, depending on their design and implementation. While monolithic kernels execute all the operating system code in the same address space to increase the performance of the system, microkernels run most of the operating system services in user space as servers, aiming to improve maintainability and modularity of the operating system.[2] A range of possibilities exists between these two extremes.
Thanks for the defenition.. but I still don't get what changes if you use a different kernal..

There are different kernels....more advanced ones are used to overclock your cpu....or reduce voltage....more basic ones allow you to run the voodoo lag fix which does not work with the stock kernel.
Currently in setting-about phone-kernal
I have the 2.6.32.9 setironkernal_1200_ver#147
Is that a good one?

I'm willing to test any and all roms, themes etc. for any devs. Just let me know. I'll be getting a different phone so I'll just use the Zio as a testing ground!
okay guinea pig... since the rom seems to be deodexed. see if any of the blackbar mods for froyo work
I'm already a step ahead of you. Ill post what works tomorrow.

Well Im going to teach myself Java because supposedly it is prerequisite for learning to develope for android. I came across good 101 Java tutorials online. I just really want to mod roms for my zio and maybe even start creating an app.
Any ideas?
I'm currently taking Linux+ so I should be of some help.

Yeah I'm not going to start taking OS classes for my major until I start taking core classes. In either case Im going to start early with Java. My school library has older editions of Java textbooks I think but I'm to check them out AZ well.

You can develop full apps with java and xml for the layout. Being familiar with linux is also a must, since android is just a linux flavor.
http://www.thenewboston.com/ is a great place for a beginner or guru. Tons of video java lessons as well as android development.
Linux has helped me with the file system. Although I still have alot to learn before I am any kind of guru.

everything of importance on android phones is written in java.
But the kernel and file system is Linux based. You have more on your phone that you wouldn't think you would have on a phone.

Yes, the OS is linux based, however all the apps are java based.

The Android platform is basically a linux flavor. It contains more then a linux the file system and kernel. Yes exactly what I posted, Java may be used in android development. That is not the only language, There are a few others including C.
Thanks for claryfing the different programming languages and their relevance to the cell phone structure and android OS.
Java and linux are both important for exploiting and developing in other words.

What is AngryGPS and why should I leave it on my phone... as I already have 4 other GPS apps I use? There is precious little information on Google about it.
Never had that app, maybe you should ask the creator of your custom rom?
I am wondering this too, Ultibread installed it on my phone and I have no clue what it is

That doesn't tell us anything about AngryGPS.
I believe it's part of Google Maps for their navigation. Weird name for a navigation system though. What if it gets angry and gets you lost?
Idk but i think is not much usefull? I deleted that from my rom and my gps is happy. It cant go angry now. Btw the performance of gps dont decrease.

Sent from my GT-I9000 using XDA Premium App
is it only on samsung stock roms? I could not see it on ICS port for captivate
It was meant to fix GPS problems for the first batch of Galaxy S devices in which the GPS was "utterly broken" and "non-functioning".
Perhaps it is used for finding the device when lost?
Just an educated guess really, but i'm guessing it's one of the apps used when you ping your phone remotely. Perhaps it's always running in the background and can't be turned off for security purposes? Hence the term "Angry" GPS. Couldn't say for sure though. Again, just an educated guess.
Don't know if anyone remembers, but this was supposed to speed up android up to 3X (3D and I/O like)
Was this replaced by JIT?!
http://www.engadget.com/2010/02/17/myriad-dalvik-turbo-hands-on-android-apps-just-got-fast/
I would think so, because that was android 2.1
JIT was in.. 2.2, right?
Yea though it shows 3D cube demo to be at a higher fps
I thought jit was going to be including this feature

No jit didnt replace it...that was a third party application (or rather framework) and it was supposed to be shopped around to OEMs. The fact that we haven't seen it yet must mean they didn't find any buyers.

I was wondering if there was any way to enable multitouch for the Zio M6000. I looked through the forum and did some searches but wasn't able to find much on that for the Zio.
Thanks
That is something that lies within the kernel. If the hardware can support multiple touch points then we would just need to compile a new kernel and build a boot image and flash to the phone.
It's not that simple. I will try messing with the kernel but honestly have never tried it before. We're lucky to even have an overclocked kernel thanks to Adrynaline.
Sent from my Zio using XDA Premium App
Yeah I believe I am using his kernal its the openzio kernel one correct? Thanks Hopefully the hardware will support multitouch. I know the Zio isn't as popular as a lot of the other android phones so there is less made for it. Luckily we have some talented people like yourself and Adrynalyne that can help out.
I may be wrong but I am about 95% sure that the Zio's screen is not able to utilize multi-touch.

I'm not sure if anyone's seen the news lately, but apparently Canonical is putting out a mobile version of its Ubuntu OS. I've seen the whitepapers so far and it looks promising (assuming it ever gets traction).
Assuming that the phone OS is open-source like its desktop counterpart, does anyone think we could possibly build ubuntu phone to work with kexec and safestrap 3?

what you're referring to, is running ubuntu on top of the existing android system
what Canonical wants, is a phone that runs only ubuntu, no android base layer (*insert Canonical's claims about how java is too memory bloated, and mobile OSs should run C/C++)
Possibly, yes. Depends on how it is ubuntu is implemented fully though, however.
If it can easily can replace the android framework and go on top of our existing kernel, then yes.
If it requires specific kernel edits, possibly, depending on how much work is involved.
But with current kexec kernel issues, it probably would not be worth it until they get sorted out

From what I've read it's compatible with most Android kernels.
From what I understand, android was written over the Linux 2 kernel. You would think that there wouldn't be much of a difference, just adapt the drivers, but then again operating system implementation isn't my area of expertise.

Yes kexec is 3.0.31 i think
I don't see why it wouldn't work, having kexec we can bypass the locked bootloader situation, unless maybe it needs a gig of RAM, otherwise if a developer takes it up I don't see any reason why it wouldn't be able to come to our good ole 3.
And yes the current kexec kernel is 3.0.31 but yet again it can be updated or changed.
I wonder if Ubuntu won't loose most of it's usability on our tiny touchscreens... I used to use an HTC Universal with a few directly ported DOS-games. The tiny screen and the touchscreen instead of a mouse made them quite hard to control. And not even having a stylo will make it even harder to controll, I guess.
