App development for CPU configuration seems to be dead especially after the once popular SetCPU app which hasn't been updated in over a year, anyone out there know why?
I guess since there's all sorts of custom kernels on XDA now do developers prefer keeping their CPU/kernel configuration apps off the market rather to use the forums to collaborate on troubleshooting and provide more information?

Hey gang, first post as you can see.
I did a search to now avail, so I ask you: I am running cyanogenmod 7 stable release and when I try to download an app from the market that is intended for OS, say 2.1+ for example, my device from the dropdown is greyed out. So I cant install it. Is there some reason as to why if we are running 2.3, we can utilize apps from the market for that level of OS?
Thanks guys!

There sure is. As I understand it, there are several ways to develop apps for Android, and some apps can be written to require a higher level of the ARM processor than the Eris uses. In general, this would be for apps like Adobe Flash 10.x, which are processor-intensive and would likely make the Eris run too slowly to handle the performance required for that particular app. There are other apps like the SPB Shell 3D launcher, which benefit either from a faster CPU or a discrete graphics processor.
Ah I see, so is there a workaround to fool the market to allow such downloads, or is that all she wrote?
Either way, love the community here and love how much life has been breathed back into my Eris.
What are some good apps to have for dev purposes or networking purposes? Is there something out there like aircrack-ng? (I know its probably not practical but just wondering.) Some java but I'm certainly still a newb.
Android apps are written in java code throw in with a few other things right ? So if your smart enough to understand aircrack-ng than it should be easy to learn android application programming...my best suggestion,get on google and look it up or market,there are tools on market for wifi type hacks but I'm not sure if there actual hacks probably just informational statistics you might need if your trying to break a key

shouldnt this be in the themes and app section?
Sorry! Still getting used to the forum and where thing's go :/
Hi there. I just got my first smartphone a couple weeks ago and I'm loving it. Samsung Galaxy SII i777 with gingerbread. I was talking with my friend today and he told me about this site and how amazing it is so I decided to check it out! However I'm incredibly lost. I see all the posts about how to root your phone and everything that says HOW TO, but I couldn't find any "WHAT IS" threads (surprisingly not in the stickies).
So could someone do a noob a favor and explain what all these different things are? Like rooting, kernel, etc. I dont plan on using anything other than the default gingerbread/ICS any time soon, but my friend told me there are tons of good benefits behind the scenes from kernels, namely getting double the battery life I'm getting now, so I definitely want to start looking into all that -- I just need to get a foundation on what's what.
Thanks in advance for the help
Read the design section from this wikipedia article about the Android operating system for an explanation of of what the kernel is
http://en.m.wikipedia.org/wiki/Android_(operating_system)#section_2
Here is an explanation of rooting and Android phone
http://en.m.wikipedia.org/wiki/Rooting_(Android_OS)
For basic definitions of terms like this google and wikipedia are great resources, as well as the stickies posted in these forums.
Now once your learn some about this things after looking and reading you will then be able to ask more specific questions which people here are very helpful with.
However general basic questions about terms and definitions like this post will sometimes generate some not so friendly responses here.

I looked through the sticky before posting, and the wikipedia links don't answer my question. I just want to know what exactly a kernel is, the different benefits of rooting your phone, etc. Any BASIC (not overly detailed) stuff people should known when first starting to do this stuff
The FAQ had "what is rooting?" and that was it..

Will add more as I find them.

The BASIC stuff you should know when starting "to do this stuff" is don't skip the details they are important and they will help keep you from making big mistakes.
The main reason/benefit that drives most average people to root their phones is to get direct access control over the /system partition and the applications installed there - to have more control over the "system apps". This allows them to debloat their device and to directly back up system apps (i.e. Titanium Backup).
Though there is allot more available to them and many different things that different people do with root. Once you have root access as the term root suggests, root gives you access to the very root partition "/" and everything below it (this means that root privileges gives you access to everything on your phone). It allows you access to troubleshooting, tweaking and theming that you would not otherwise be able to do.
Just remember the saying "with great knowledge comes great responsibly". Because once you have root access, you can then give applications that same root access - and that will allow that app free run through everything on your phone, as well as any and all accounts you have sync'd to your phone. So be careful to be stingy with what apps you allow root privileges, because if you allow a rogue or pirate app such control it could do quite allot of damage and steal quite allot from you before you ever know what happened.
As to exactly what the kernel is (summarizing part of the Wikipedia article says because it does tell you exactly what the kernel is) - the android kernel is the core of the android operating system (just like the Linux kernel is the core of the Linux OS as the android kernel is built directly from the Linux kernel). The kernel is the part of the OS that allows the user input and application inputs to interface with the hardware - it is the drivers and communication translation between the user controls/applications and the hardware it operates on.
So I'm fairly new to android having been on the iOS scene for quite a while now, and I've always jailbroke my phones to get the most out of them.
Now I've started using android, I'm interested in rooting but don't really fully understand it yet. Custom ROMs, Kernels etc etc, its a lot more in depth than jailbreaking and I was wondering if there were any threads, or sites (or anyone willing to post about it) explaining what its all about, the benefits, drawbacks, why people do it etc so I can get a good understanding about it before I start messing around.
Any help/info would be greatly appreciated.
Rooting is a way of allowing apps to get superuser privileges. Also for modifying parts of the OS that you couldn't normally access. The advantages are that you can flash custom firmware. Remove stock bloatware. Block ads. Do cwm backups. The kernel is the area between the phone os and the hardware. Different kernels tweak different settings. Which one you chose will depends on what you want to achieve. Performance battery etc. I wouldn't worry about kernels for.the moment. Rooting the SG3 currently does not change the stock kernel anyway. Look for xda member chainfire he is the man to follow. All I can suggest is read up on the forums as much as you can. Don't touch a thing until you understand the core of any instructions your attempting to.follow. Good luck

The main reason for jailbreaking is the ability to sideload apps (install apps that are not from the official market such as alternative keyboards, Emulators, ...) e.g. from Cydia.
Android phones already support this feature out-of-the-box, you just have to tick the corresponding box to confirm you understand the risk of possible malware when installing apps you found somewhere on the internet.
Based on this feature there exist several alternative markets, SlideMe and Amazon being the most popular.
Additionally Android allows you to modify most of the system starting from the launcher to dialer and up to low-level features such as equalizer and notification LED control by installing a corresponding app.
Root gives you access to far more low-level features such as backing up apps including their 'secret' data (Titanium Backup), getting the S3 to use mass-storage mode, remove Advertisement (AdFree), get detailled informatiaons about your phone's battery drain (BetterBatteryStats)...
Samsung ROM's have gotten better but people always want other, new or changed features or upgrades to OS-versions Samsung is not officially supporting. For instance the old Galaxy S1 never got an official upgrade to Android 4.0 but the Cyanogenmod project made it available.
Samsung-Kernels obviously do not support such features such as overclocking the CPU (which I wouldn't recommend anyway on the S3) and have good but not excellent optimizations. E.g. the sound processor can gain huge improvements by simple software optimizations (Voodoo Sound) and the phone feel much snappier with tweaked CPU scaling algorithms. Additionally custom kernels can e.g. include NTFS support which Samsung does not provide due to license and potential stability issues.
In conclusion I'd say, stay with the original ROM if there is nothing that really bothers you but I'd recommend flashing a custom rooted kernel such as Siyah as it brings direct improvements.
Thanks for the replies.... I'm trying to find as much as I can to read up on, but I'm yet to find a decent website with some info explaining everything from the start. I prefer to know exactly what everything is, what it does etc etc before I start messing around.
Anyone know anywhere I can find this info, threads containing beginners guides to rooting or something similar?

Here is a good guide on rooting http://androidforums.com/evo-3d-all-things-root/389787-beginners-guide-rooting-android-devices.html
Google is your best friend. I am going to add a section on my website www.modmymobile.co.uk with a simple breakdown.
Have a look on YouTube there is a few step by step guides.. only downside to rooting is you will lose your warrenty
As we see that there is big list of android apps for the particular thing and activity. How can one identify the mistakes made by the android app developer that even a Lehman can understand who generally use the Android phone and don't well acquainted with core technical stuff
