I have a confusion regarding android. this is very general query.
In Computer, first we have to have exe file to install anything and then we click on it to install the app on windows computer generally. when the app is installed on computer, we have installed app files in program files and then a dump (that is exe file) which we keep to install this app on any other computer.
Now, please let me know if this is applicable in android phones also?
I know that in android, there is .apk file instead of .exe file in computer. I observed that after installation apk file disappears. Is this true?
Not sure if in understood well, did you mean if instal anything from SD card? If you are asking that the answer is yes, i install everything from SD card and the apk file stay there after installation.
What if u install any app from Market?

Even in Android you can see the .apk files under /system/app. Also applications installed by you can be backed up & later restored using software available on market.
"Normally" these apks dissapear when you download from.market, but all of.your apks are stored in your phone, the thing is that you have to hav permission to do that, when you download an apk (the single file) and store it in sd card to install it, the apk is copied to the phone.

But if u back up ur apps as .apk and install them later using softwares (with exception of Titanium backup) u will loose connection between the app and android market (that means no updates)
the best option is to backup ur apps with titanium backup along with user data and restore it using the same
how do i access /system/app? Do I need to root the phone in order to see this directory?

Download Terminal emulator from market & you are ready to go to /system/app !!!!
You can also download Root Explorer and so the same
Thank all. Can you please confirm what I am writing below:
Suppose I buy a android phone (with android 2.1 so you cannot install apps from SD card) in which I installed an application named XYZ from Market. Now, there is a apk file for XYZ which gets downloaded somewhere in the phone memory and then it gets installed automatically.
Now, I just want to know, where does this apk file go after XYZ is installed? Does it stay in phone memory with the installed files of XYZ.
If it goes to phone memory and not deleted from there, then phone memory
if u install .apk from market it will be stored and installed in /data/app in phone memory. i do not think it is stored twice in the phone.
Do u mean to say that only the installed file gets stored and. apk. File got deleted automatically after getting installed?

Remember that an .apk file its a variant of the .jar files when you install an .apk this file gets stored inside the phone along with its necesary dependencies when the app starts, the os reads this file line by line while the app is executed.
In short terms the .apk file its the application itself that need a proper interpreter to run, in that way when you install and app to the phone, it copies this file and links the dependencies, so the .apks downloaded from makret are stored directly inside the app folder, in that way you can extract them from this folder and use it in another android phone.
You are relying too much on the windows ways of things. You see an exe file installion in windows essentially unpacking everything (other things aside) where it is needed and you then often see a bunch of files and folders. This is not what happens in android, the apk file is conserved when installed and can be found in the root part of your phone. Its data/app/ if installed on your phone, mnt/asec. (or something like asec) if installed on your sd card. You can copy that file to your sd card or send it to another device and install it again. I did just that today (I sent an apk to a friend)
anyway i dont think its same if i delete .apk + odex files from /data/app as i uninstall it with titanium backup. i think TB will be delete also data stored by the app inside the database (its the place where the apps are saving data, settings, etc...)
In case you are installing from Android Market:
1. When you are at market, it doesn't ask you to download. You will only get option either to install or update the existing app.
2. If you are a normal user, after installing, you won't be able to see the apk file anywhere on your memory card. But if you are a root user or with the help of special file managers and specific apps like root explorer and terminal emulators, you can locate those spk files in the phone's hidden memory.
3. If you are a root user, or with the help above mentioned type of apps, you can locate the apk files in phone memory and copy it on your memory card and distribute it to your wish.
4. If you are worried for paid apps and losing your phone or apps because of resetting or any other reason then stop worrying. A record of your paid apps is stored in google servers. So, even if you reset your phone or lose your phone, once you log in to a your new android device with the same google account, it will automatically show your paid apps. You don't have to pay for it again. Just need to install it again. This is applicable only if you are paying for the app through android market and you are logging into your android device with the same google account you had before losing your apps.
In case of installing via your SD card:
1. apk files are just like java files (.jad or .jar). You can download it on your PC from various sources and transfer it to your SD card or any of your friends' via USB, bluetooth or any other way.
2. After transfering the apk file to your SD card, it doesn't get automatically installed. You have to click it or open it to install, just like how we double click the exe file in windows.
3. Whether installed or not installed, the apk file you transfer to your SD card will always remain there unless and untill you or someone else delete it or you format your memory card.
4. Once installed, a copy of the same apk file would also be there in your phone's hidden memory, which you can access using special apps.
If you worried about losing your apps, try searching for other apps which backups apk... you can do so at android market. Moreover, also search on the net about having root access on your android device.. it'll let you access files in your phone's memory.
I hope, this would solve down all your queries !!!
Thanks next2 devil. Very gud explanation. It cleared almost all confusions. I have some more confusions that i want to clear out.
1) just a general query that just like exe file got unpacked after double clicking on it and install its files in c: genrally, does the same happen with apk, jad and jar files?
2) just want to clear out that phone memory which is hidden for normal users contains the copy of only those apk files that are currently installed on the phone and not the ones that are uninstalled or not installed at all?

1. I am not sure about JAD and JAR files, but yes, APK files unpack itself to get installed. You can come to know the exact size/space that would be taken by the app directly from the android market. Details would be given there.
2. Yes, the phone memory would be having copy of files only which is installed. There would be no copy of any apk file which in not installed.
Thanks next2devil. Your response give rise to one more query.
if i compare unpacking logic from windows, there is no need for original exe file to remain in existence after it has been installed and user can delete exe file after installing it. Deleting exe file has no negative impact on the working of installed app. Please let me know if this is also the case with apk files? If yes, then what is the need of apk file to remain in phone memory after it has been installed?

Short and simple. Deleting the apk file from /data/app removes the app.

I am a bit stuck... I rooted my Nook Touch using the TouchNooter method. It worked well and I can install apps from the market easily.
But I think I missed a step. I want to be able to access nook system files on my computer and can't seem to figure out how. When connected via USB, I can see the normal Nook folders for adding books and such but none of the system files.
I want to be able to add/remove apk's using my computer. Is this even possible?
The easiest way to do this is copy apk files to your SD card and then use ES File or Root explorer to fin and install them.

Even Astro get to install apk, and it's free on market.
While the OP can get Astro she will not be able to see the system files with that. ES File allows access to root files and is free as well.
I have not wifi and any file mangers
I rooted my nook touch.
I have not wifi (unavailable to me)and any file mangers (root explorer &...) how can i install file manager in my nook ?
I want to be able to install apk's using my computer. Is this even possible?
you can install using adb throught wifi. google adb.
I've successfully rooted my touch, and am trying to install Messagease & Instafetch.
Using ES File Explorer, I can't gain access to /system/apps, which is where i'm told they need to go- ES File won't go navigate above the SD card, although I've enabled root access & /system mounting.
i've tried copying the apks to an sd card, but install fails due to non-market issues, although i've enabled installing from non-market sources as well (as far as i can tell, anyway- maybe i have to do that in another place too?).
any ideas what I've done wrong? let me know if i need to post any other info. I'm using LinuxMint.
thanks!

If you enable it using Nook Color Tools, you should untick and tick again the checkbox to make it work
Also, it may be possible to access the system partition booting with noogie.img ...
merci mille fois!
sorry for the question, but is rooting a 2nd time with noogie.img a bad idea, or will it just overwrite the image i created with touchnooter?
thanks in advance,
-steve
i may have figured something out: i remade a new image with noogie.img, the rebooted the nook with the sd card in. once the "rooted forever" appeared, I plugged in the USB and 7 partitions showed up on my computer screen. i was able to access the files there and put the messagease.apk and instapaper apps in there that way.
thanks again!
My wife has a NC and likes it the way it is, i.e. BN store, but I would like to add an app that does not require root. I was thinking that I could use a clockwork recovery SD card with a zip of the app, just like we do with google apps.
Will this work?
How do I make a apk into a flashable zip?
The app is You Version Bible
Thanks
-EDIT-
So I have figured this out, it is possible to install apps (that do not require root) with out rooting anything. I would call it side loading via CWM sd card.
The key was to use the mount paths from ManualNooter (\META-INF\com\google\android\updater-script)
0.1.) Get apks for you apps (either with titanium or copy from 'data/app')
0.2.) Get a apk for 'Nook Color App Manager' (search the android market, can't post links yet)
1.) Start with the ManualNooter file and remove all folders but 'data' and 'META-INF'
2.) Delete all files in the 'data/app' folder
3.) Place the apks you want to install in the 'data/app' folder
4.) Edit '\META-INF\com\google\android\updater-script' using a programing text editor (otherwise you will not see the line spaces) remove all sections except the following: 'Mounting partitions...' 'Installing apks to /data/app...' 'Unmounting Partitions...'
5.) Save the script file and put all this back together in the zip.
6.) Use the CWM sd card to install the file. (if you don't know how, use google)
7.) Remove card and reboot after done. A new app App Manager will show up in your nook app list, go to the home page to run it and add links for your new installed apps.
Note: I did not post an files as I used other peoples work i.e. GMPOWER and apps from the market
So I have done lots of research and even tried this. I think I got the app installed but in this case there is no way to show the app in the stock launcher as it only lists apps it installs.
For reference I will include the procedure to install apps via CMW(Clockwork Mod Recovery)
Thread
You download the file attached to post 17 in the above thread, it is a empty zip that can be filled with your apks that you want. Simply place the new file on a CWM sd card and install the file via regular instructions in the above post.
If I ever find a script to add a link to the stock launcher I will post that and then this might be a usable idea for side loading apps.
I have a newly rooted Nook Simple Touch (NST) that was updated to firmware 1.2.1 before NookManager worked its magic.
The problem is that now I cannot take advantage of the Kindle App, ES File Explorer, or NGAppsAttack because I have no way to install anything.
Here is what I am running into.
1. I cannot install from the browser that came installed when NookManager did it's thing because it appears to have a problem with the certificate for any site except the default Barnes & Noble page, rendering my browser useless.
2. I cannot use a file explorer, such as ES File Explorer, to install a new version of the certificates or a new browser because one didn't come with NookManager's install and I have only ADB Konnect, Contacts, Device Registrator, Gallery, Library, Music, Nook Friends, Nook Touch Mod Manager, Nook HW Test, Settings, Shop, Social (doesn't work), SuperUser, and TestCenterService. I uninstalled Amazon AppStore because it didn't work and I read elsewhere that it was no longer working.
3. I cannot use the market app because there are no versions already installed, begging the question - now how do I install stuff without a browser, market, or file explorer?
I tried using NookManager to install things by following the directions elsewhere and extracting apps from their zip folders directly to the root directory of the NookManager MicroSD card. That failed on every app I tried because when I booted the NST off the NookManager card, there was no option for Custom under More! I even tried modifying the menu text file using Notepad++ to add the Custom -> menu item under button 4, but when the Custom menu came up there was no button response. Evidently, it couldn't find the APK files extracted to the root (in this case E:\) when I tried the extraction method.
Does anyone have a better idea? I mean, I'm not a programmer - so although there is probably a way to do it through ADB Konnect, I would need someone to explain it in baby steps.
Maybe I could image the SD card with an image that just installs apps?
Thanks!

You should be able to copy an apk file to the SD card and use the folder browser of Relaunch (which was installed during root) to install the package. Just open the folder where you copied the apk from your PC to the SD card and touch on the apk file.
If you need some apk files like ES, a browser, etc., check out my post here which includes a link to a zip file of potentially useful apps.
The certificates issue has recently been addressed. Look here and read a little further in the thread for some simplifications. But the resident browser is worthless and can be uninstalled.

I assume you are referring to an old NST or NSTG, not the new Glowlight Plus.
You've come late to the party for the PlayStore. Google has rolled up the welcome mat for devices running Eclair (Android 2.1) as of June 30, 2017.
You can side-load apps using Relaunch by transferring the apk files from your PC via USB to you Nook (place in a convenient folder, preferably on the SD card). Using the file manager capabilities of Relaunch, navigate to the folder where you copied the apk files. Touching on the apk file icon should bring up the option to install.
You can find various apks by searching with Google or trolling the forum here (a bunch that work in the link in my signature).

If your USB drivers are installed correctly you should see two "drives" when the NST is attached. One is the user accessible internal partition. You can copy over apk files into the "My Files" directory there if need be, as long as you can navigate to that folder using Relaunch, and install from there as described above--at least I think you can. The second "drive" should be the SD card which will show a similar directory structure unless you have added folders yourself.
There is no way to access all files on the internal memory via USB. Only the user data partition can be seen. To get to anything else you need a root browser (I think Relaunch has settings which enable root browsing).
If you're not seeing the SD card you either have an issue with the USB connection or there is an issue with the card itself. Can you see the card with Relaunch?

Yes I can see the card using Relaunch. And I was able to copy the apk into the My files directory, however, I was trying to figure out what the exact path is to specify in the Relaunch file browser/explorer so that i can see and install the apk? Do you know what it may be?

Parsing errors generally mean the Android version is incorrect. That would not be the case for apps from my zip package.
How did you root your Nook?
Edit: try moving the apk files to the SD card and retry the install
