[rooted NT using Albert's 4.5] old school IT guy, just don't know android
This site doesn't seem to be very welcoming of basic questions so I would like to find a place I can get up to speed. I'm reading and searching but most of the answers include elements that are over my head so I don't end up making much progress. I've also tried the basic Google searches for "android for dummies", "android basics", etc. Part of it is that I haven't used a smart-phone, iPad, or other similar device so a lot of the really basic stuff isn't 2nd nature to me.
Where can I go to get a basic understanding of setting up, configuring, and using android efficiently.
Things I would like to understand:
When ICS (CM9?) becomes available on NT, if I am running CM7 and do an upgrade will all the look/feel & organizing configuring be gone and need to be redone with the new OS (does this happen each time you do an OS upgrade)?
Configuring the launcher(s) to get better look, more efficient use. I have read the honeycomb & homescreen configuration threads but am unclear as to whether those options are available with a rooted NT or only if you have installed CM7.
Just basic efficient navigation. If I am bouncing back & forth between apps (like Dolphin & installing/configuring an app) I currently end up using the "N" key to go back to the launcher and "reopening" each of the apps. Don't know if there is a more efficient way to bounce between open app instances.
A sincere thank you for ANY help. And sure if you would rather ridicule me for my lack of knowledge or point out that there is a search button I can certainly handle that too.
Honestly, just play with it and explore. You're not going to break anything. In the unlikely event that you do simply reformat your device.

Hi! Since i assume you are well aware of conputer operating systems
Android is a derivative of the Linux kernel which powers Ubuntu, Red Hat, Gentoo etc. Linux is based off of Unix as are other OS like Mac OS X. These Kernels use unix commands to carry out tasks underneath the X server interface (desktop). Android has a similar setup and you can issue commands from a terminal either on the tablet itself or in windows to install, remove and execute scripts and programs. ADB is the android equivelent of a com2 port if you will and that is how the NT and
Kindke Fire where originally rooted. You can use Indirects Adb script to root your tablet and even install Google apps. I know you already have one of Alberts cards but if you want to learn up on Android you should study up on ADB.
The version of Android that comes with the NT is fine if you just want
to consume books and media. This is Gingerbread 2.3 that
was developed specifically for the NT. Since Google requires manufacturers
to meet certain requirements to license the proprietary parts of
their software and apps and Barnes and Noble decided to forgo licensing
they could not include Google Apps on their tablet. This is why although GApps can be forced to run, there are still problems.
Cm7 is a heavily modified version of Android Gingerbread. It has the code in its
kernel 2.3 to run the Gapps without problems and allow full
Access to the market. Some of the "new" ICS roms that are
being built and distributed are actually based on Cm7 and the new
Code is being backported to work on the old kernel. This means whenever
A new feature is introduced to ICS, it has to be rewritten
to work on an old kernel. There is work being done to build
a working 3.x kernel which is what ICS will be based on.
I personally will wait and hope that development is completed
before i use ICS.
The launcher is what draws all the icons and gets you around. I personally like go launcher, others like ADW (cm7 default). Zeem launcher is lightweight and basic.
Just try a couple and use home switcher from marketplace to switch between then
Until you find the one tgat strikes balance between feautures and speed. Hope this helps you get started.
Thanks much for the help so far. I do appreciate it.
I have spent some time with the FAQ/Newb thread but will spend more time on it.
Check out the XDA wiki, or the CyanogenMOD wiki for the best vanilla-android questions. Things like how to set up the android SDK, downloading drivers, etc.. Anything from beginner to advanced should be found in one of those 2 places.
The search function here is sufficient. You just need to know what you are searching for. Basically typing in "android for newbs" is gonna return probably every post with the word android in it. Good luck finding anything in that mess. You need to be fairly specific.
A lot of people here are more than willing to help, so long as you post in the correct areas and at least try to search for an answer to your question.
Just spend a lot of time searching through XDA and using google searches. There is a TON of information out there, I know it seems a bit overwhelming at first, at least it did for me when I got my first Android phone. As long as you are willing to put into the time to research and use trial and error, you will be fine I would start with reading how to root the device that you currently have, from there learn how to install CMW and then worry about CM7 and other ROMs. As you are learning these things I believe a lot will fall into place.
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
Hello, I'm new to this forum, but, I have been in other forums relating to hacking 'mobile' devices. Previously, I was part of a number of different iOS forums, so, I know about jailbreaking, and troubleshooting problems on the iOS platform. I'll also share my few thoughts on Android, and my experience on Jelly Bean so far within this, embarrassingly long, post.
However, with Google's announcement of the Nexus 7, I was impressed by Android, and I was thoroughly impressed that it had finally sorted out the lagging problems. (I had used Android tablets, but they never appealed to me due to the lag which each one experienced. Jelly Bean, and, in particular, 'Project Butter', has remedied this issue - I have experienced no lag on my Nexus 7 since I received it a week ago.) And so, I pre-ordered the Nexus 7 - deciding against purchasing, a much more expensive, but, I believed, an excellent tablet, the iPad.
iOS, also, was beginning to become less interesting to use - sure, the iPad may have a larger scale of the iOS mobile operating system, but it remained largely the same. Same interface (although on a, admittedly, much better screen) same apps, same freedom - without the jailbreak. The new iPad (as advertised and sold by Apple), I thought, also did not do an excellent job on improving it's predecessor. Sure, an improved screen, and processor to power the screen - but is that worth it? (Considering another one will, inevitably, be released within a year.)
Tegra 3 was making strides. Although, one thing that saddens me about Android, and is something which definitely hinders it's ability to overthrow iOS - is the fragmentation present on the operating system. I'm not sure which apps are compatible with my Nexus 7, and which ones are not. (On a side not, piracy is also another factor which slows the progress of Android, and is perhaps a reason why some apps are exclusive to iOS in the first place - I'm looking at you Epic Games! Android certainly has the power and graphical capabilities to run the game, but Epic, like all companies must, are interested primarily on their profits. Again, fragmentation plays its part!)
Although, shifting to different mobile operating systems is rather difficult - especially since I am intrigued by modifications, and altering devices to make them fulfil my needs. On iOS, it was quite simple: There was only one thing to do - jailbreak. A process, which in itself, was extremely simple (for the most part.) It appears there are also much more iOS specialists on YouTube, who post easy to follow tutorials. Also, since iOS is a 'closed' platform, I was not concerned by viruses, and I knew what I could, and could not do.
Android, however, is open - and this, paradoxically, limits myself. There are so many modifications, I do not know which ones are good, which ones are bad, and which ones could result in bricking my, now beloved, Nexus 7. I don't want to completely mess up my device, or install random rubbish which only makes it slower. I have, almost literally, no clue on where to start. Sure, I've downloaded a few basic apps from Google Play - TegraZone - but who cannot do that without assistance?
I want to install more widgets, that amaze me, and also applications which will prove useful. (For example, a file managing app, a torrent app (no piracy! ), and other cool things.) I also, though, require a reliable anti-virus. Having previously used iOS for a number of years, I was not subject to any viruses, and, indeed, I did not have to worry about viruses - there are very few, if any, viruses on iOS. Android, though, is much more open to viruses. I need to ensure that I do not succumb to one.
However, what I am most interested in is the 'rooting' process, and the benefits which can derive from it. What extra things can I achieve by rooting my Nexus 7? What applications should I install to supplement the rooted device? (I have read of ClockWork(?)Mod, but I have not really ventured that far into applications which take advantage of rooting, since a lot of the information mentioned appears to me as gibberish, due to my noobishness .) And, perhaps most importantly, if something were to go tragically wrong - how would I recover the device. (Again, I'll make a reference to iOS, since, it is an operating system I am familiar with - you could simply restore the device through iTunes - what is Android's alternative?)
So, can you assist me in getting accustomed to the Android operating system by providing your recommended apps, and also useful tutorials which I can use to develop my understanding? I literally have no clue what half of the things in the Android section of this forum talk about - they included an abundance of vocabulary which, evidently, you need relative experience to understand. I also need require some Android experts - involved in perhaps development - to follow on Twitter!
Thanks for reading through my essay! Please, help a noob get started! I would appreciate all forms of feedback!
Note: I have downloaded the Android SDK (Although, not installed it, as of the time of writing.), and I have also got the factory image for the Nexus 7. I achieved this by briefly viewing a YouTube video. There do not appear to be that many, though. The XDA YouTube channel generally covers the news aspect of all things related to Android.
The greatest bit of advice I can give is to start here - Nexus 7 - and read read read!
There's no backup and restoring the entire system without root. When you do you can install a custom recovery. Note there is always a stock recovery that is far limited compared to recoveries such as CWM.
Android really doesn't have problems with viruses. Seriously. The only reason why it appears so is because idiots sideload apps from shady sites that contain viruses, but on iOS there is no sideloading without jailbreak.
For a file managing app, you can use Explorer (my preferance), ES File Explorer, or Astro.
Widgets are really personal preferance, I keep a music widget to quickly play music, a calendar widget, weather widget. You might want a news widget like Flipboard.
Rooting gives you full access to your device. It allows performance gains like overclocking, battery saving with underclocking. Like I said before, it opens to ability to backup/restore entire systems and individual apps with Titanium Backup. You can install customs ROMs, delete system apps (usually bloatware), remap the physical keys, use Tasker for automated tasking (pretty awesome btw). You can also edit system files, such as notification tones, ringtones, bootanimation, etc.

Welcome to Android!
I think you'll enjoy it
Ok on to your questions:
These are gonna be out of order
Reliable anti-virus: Trend Micro Mobile Security (worth the $10 )
Benefits of CWM: Backups, restores, custom ROM flashing
Benefits of rooting: custom ROMs, access to system files
Some apps to get started: Angry birds , Rom Manager, BatteryCalibration, ES File Manager, imo
Android's alternative to iTunes' restore is CWM. It's not official but its tons better then iTunes. You do it from the device and its a full, complete restore.
Ask again if I didn't answer something
Very long post BUT a few things to think about.
I have never used a antivirus software and really they are pointless just look at the apps before you download them read the comments and look at the permissions the app uses and think "does that fart noise app need to be able to send texts" of cause the answer is no so don't install it.
Other fractures can be useful like phone tracking but there are better apps that are free for this like prey.
If you root you will have full control of your filesystem much like su on Linux if you have ever used this. You could for example with root use my project to run Linux distros like Ubuntu. The nexus 7 due to being under googles power is very easy to unlock and root and if you mess something up easy to restore a backup. There are other great apps to like being able to back up apps and there data.
Just a few points and if you have more questions feel free to pm me

AVG or Avast antivirus are the best.
Solid Explorer is the best file explorer.
UCCW is the most customizable widget.
Taptu or Pulse are the best news readers.
Pocket.
Tapatalk forum.
MX player is the best video player.
Dropbox is by far the best cloud storage.
Photoshop.
PowerAMP is the best Music Player.
I would say that you don't need to root a Nexus Device. You got the latest OS and will always have.
The only reason you would wanna root is for some root apps.
Like Titanium Backup, AdBlocker and ROM Toolbox.
CWM is only necessary if you want to flash a custom ROM and you don't need to because you already have AOSP Jelly BEAN.
Thanks for all of the responses! And apologies for the long post! xD
I'll look through the Nexus 7 forums as XperienceD mentioned.
And by ClockWordMod - is that actually ROM Manager? I'm confused, and this is probably the most noobish question you'll get. xD
Since I don't really want to root my Nexus 7 (currently, that is) - then I would not really need to back up the data, since, there will be no risk. I'm not really concerned about overclocking my device - it's quite fast as it is. However, battery saving is quite tempting. Although, I don't see it as a reason alone to root my Nexus. And, as it is stock Google - there is no unnecessary bloat ware attached to the device.
And I can't get viruses while browsing through the internet?
I always thought that was the case, which is why I was looking for an anti-virus application.
Also, for UCCW - do I need to install a custom launcher of some sort? Is it really possible to add a widget, that appears complicated, simply through the Google Play market?
And finally, while installing ES File Explorer - I noticed that it had permission to remove shortcuts without user intervention. Is this the sort of permission I should be checking for on other applications? Since people on this forum recommended the app, I didn't really have any doubts of whether it was legit.3.
Also, how you I get toggles back on the notification bar? On iOS (sorry for the repeated mentioning of the scum ) - I had SBSettings, which was similar to the notifications available on Android. How would I add the toggles back?

It is a custom recovery which lets you backup your ROM, flash new ROMs and make other changes to your device (so in a way use it is a ROM manager)

This is true if you have a nexus device the need for root is far less, and the fact that alot of apps that used to need root have become features in new versions of android, back in the days of 1.5/6 you needed root to pretty much do anything good

Sure you might get windows viruses but in no way will they beable to run on your device let aloan harm it. The only way anything evil can be done is if you install the app (and in alot of cases give it root) so check those permissions!
anti-virus apps are the biggest scam (well paid one anyway) all they can really do is check a database of known bad apps and check it its there, other than that they do nothing. They are a trick from all the Windows users coming to android after having it hammered into them that you need anti-virus

Nope just add the widget to your home creen, in the app launcher press the widget button and then long press on the widget you want and drag it to the home screen you want, many apps include widgets so will be installed with the app as part of it (e.g twitter) while other 'apps' are just widgets

There is likely a good reason for this (And with alot of apps if there is a odd permissions it will say in the apps description why its needed) but yes its the kind of thing you have to stop and think about

to add toggles you would either need to use a custom ROM, or download a app that will do it like this one https://play.google.com/store/apps/details?id=de.j4velin.notificationToggle&hl=en
Thanks very much for your detailed and extremely helpful reply!
I'll just do what you recommended! The Notification Toggle is an extremely impressive app, I must admit.
Since there is no point downloading a paid antivirus, should I download Avast Anti-virus (since it's free), just for precautionary measures?

Well its not going to hurt and would at least prevent an app thats bad be installed if you missed it. And like I said some do have some nice other features just the "anit-virus" side of it is rather pointless
There is a huge thread with skins for UCCW.
And Power Widgets or Notification Toggles are the best Notification Drawer toggle apps.
NT has customizable icons.
If you want weather too there's some new app called Deluxe Notification Bar which shows weather and toggles.
Look in the Nexus 7 forums for no-root battery saving advice.
And if you do not want battery drain don't use Anti-virus.
I've never had any virus problems.
If you're unrooted they can't really mess with your phone.
Just stay away from creepy apps, Chinese apps (no racist), piracied apps and apps from other than Play Store and XDA.
And never play ad-supported games.
Buy ad-free versions or play offline if you don't want battery drain.
Also SwiftKey is a MUST, if you're not happy with Jelly Bean keyboard.
I'm not a developer but I have knowledge about Linux and how PCs in general work. Is there any book/course that explains how android works on a deeper level? I'm not interested in apps or user UIs, I want to know the deeper levels like how partitioning works, how the OS is loaded, why some bootloaders are locked by default, what a custom recovery is or what is the first thing to load when you power on your phone/tablet (do phones have a BIOS like PCs or anything equivalent?). Thanks in advance.
I'm also interested in this, but I think the answer is it's a bunch of undocumented proprietary baseband processor junk nobody will share for the boot, then the rest is basically a Linux distro made by 1000 monkeys on 1000 typewriters copy/pasting stuff provided by their hardware vendors together, and the components of that also probably have no documentation or incorrect documentation.
Just browsing through directory structures on a rooted phone there's so much unused and inaccessible junk like config files for really old versions of android, random vendor apks that aren't configured, and firmware for other processors strewn all over, sometimes multiple copies of the same structure, that it makes no sense. It looks like a bunch of vendors gave their support libraries to manufacturers with the intent they'd delete the unused parts and copy the used parts in, but the manufacturers don't understand how to do that so they just paste the same full directory structure several different places until it starts working.
If it made any sense, some people would just learn it and rooting new phones wouldn't be hard.

The rabbit hole goes as deep as you want it to. I have plenty of information to get you started. Happy digging!
*A general overview of the android boot process, thanks to the Lineage OS developers.
*An old, but good read on reverse engineering aboot.
*And a much more recent article on reverse engineering android. It gets very detailed in this one. It also goes into the low level processes of android. Like; What loads the bootloader? That kind of stuff. I think this is what you're after. Hope it helps.
About the bios question. The short answer is, "kind of". They have a very simple and proprietary one that's not easy to access. It also does not function in the same ways that a PC bios does. It's more like a motherboard programmer. It's hard to explain. The last article goes into some of that.

About the bios question. The short answer is, "kind of". They have a very simple and proprietary one that's not easy to access. It also does not function in the same ways that a PC bios does. It's more like a motherboard programmer. It's hard to explain. The last article goes into some of that.

Do you know if there is any tool that lists all the various initscripts and settings in use on a running system? I'd like to remove Google entirely from my phone, but there are so many firmwares and initscripts all over the place that I can't even figure out which ones are actually used to run the system. Half of the settings files, properties, and commands return 0 results or 3-4 useless results when searching for them on the internet.

The best way to remove google entirely is to flash a custom ROM or GSI if your device supports it. You really only need to look in system/app and system/priv-app for google stuff. Some phones use stock Google apps for things like the Calendar or MMS. So, to run google-less you may need to replace some system apps as well. Just a warning, even if you already know this. Removing certain apps, even google apps, may cause problems for normal operation. Definitely make a backup before deleting anything in the system.

I'm no expert but have been running lineageos 14.1 for some time now. It is a version of android 7.1 in which everything google has been removed. I use it with microG which replaces google play services.
You may wish to look into it instead of re-inventing the wheel.
I use it with a firewall (AFWall +), and Xprivacylua for additional privacy.
