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.

Are you using the google market? Allot of apps don't show in the Amazon market. If it isn't in the google market you could always sideload it.

<Root Explorer apparently cannot be side-loaded due to protected app. It appears that you need to install directly from the marketplace or another android application store.> - edit... others said this was incorrect and they were able to sideload Root Explorer. Not sure why we had issues. I was assisting a friend get his Market working and found that Root Explorer was no longer listed on Amazon App Store. We did find it on AppBrain, but the AppBrain app wouldn't install on the KF.
In the end we found that ES File Explorer had a 'unprotect system folder' option that allowed the Market APK to be moved into System/App. His market is now working great. Hope this helps. You should be able to fnd ES File Explorer on XDADev or on the Amazon App Store (free app).
I finally got it uploaded and now i save the apl files to sd card and when i go in to move them to system > app it sas that "you can not paste becasue the file system is read only and when i try to change the permissions it give a weird error
please help
i have ed but i cant find unprotected folder ou spoke of. please tell me if i did this wrong but i took the apk's and just put them right into the sd card....is that where the are supposed to go before the sys>app folder?
how about installing it via adb? adb install <path to apk>
help please!!
when i try to install the andriod market it says' "the application market (process com.andriod.vending) has stopped unexpectedly. please try again.........please advise, also i have the vending.apk in the sys/app and when i try to change the permissions it says that vending.apk permissions can not be changed because the file system is read only
thank you
every time i try to do this when i try to mount it with...C:\Users\Guest1\Desktop\Android\android-sdk\platform-tools.... it says "remount failedperation not premitted

You must not have root access. You should be able to change the file system to r/w if you have given superuser permission. Are you sure you have root access? What program are you using? (Super manager, root explorer, es explorer, etc.) Did you try using adb to change the permissions?

You could use ES File Explorer from the amazon appstore. Just enable root mode.

Just for reference, root explorer side loaded for me perfectly fine.
And you cant write to those protected folders without having root enabled.

My buddy kept getting an error that the app was unauthorized when trying to side-load. Tried to move it from sdcard/downloads to data/app and reboot and received the same error. Good to know Root Explorer can be side-loaded without having to install from the market directly if necessary. He was able to sideload all the other vvpGoogle apps and etc fine.
For anyone who can't download Root Explorer from the Amazon app store (I couldn't as I'm in Hong Kong) google root explorer apk and there are a couple of links with the apk for direct install - I think I registered for Mobiles24.com to get that and it worked fine for me.
However, I could only rarely change permissions with Root Explorer so I also searched for "Super manager android apk" which was better and easier to change permissions with. I also just started looking for Filestube/Megaupload links and then transferring by USB before installing with RE or SM
Still haven't got Android Market working - it loads and just says, "waiting for download to start"
I wonder if it's because it's my first Android and I don't have any devices listed?

I had the same problem. From what I can tell its the vending.apk
It would install and load fine, but no downloads would ever actually kick off.
Use the market apk thats in that gapps zip with the rest of the apps.
From what I can tell that's the newer market anyways and flashier than the vending.apk one.
That gapps one worked first try for me.
root explorer error
Hi all
New to this, total rookie, so please be patient
I live in Canada, got fire so trying to get droid market place. As far as I can tell I rooted it correctly using superoneclick. I cant access amazon market.place from Canada so I got root explorer from mobiles24.com and installed it on my kindle (I assume this what is meant by side install)
So now when I go to run it, iget the following error.
The application root explorer (Process com.speedsoftware.rootexplorer) has stopped unexpectedly. Please try again
Thoughts on what is causing this?
There root guide for Linux/Mac includes the APK and automatically installs it. You could follow the steps the script uses to install, or just sideload it.
I side load'ed mine. No problem

This, although it's not as obvious to switch to Read/Write as root explorer. Menu->Setings->Scroll to the Bottom->Check Root Explorer->Yes on Superuser Prompt->Check Mount File System
What I did though was, I pulled the APK for Root Explorer from my data/app folder on my G2, then put that onto the Fire.
Then using ES File Explorer I installed Root Explorer.
Hi,
In my SGS4 i got a folder called "Baidu", I do checked and deleted and it comes back after few seconds after deleted.
I had removed some app's to test and nothing works, the folder come back.
I don't use ES File Manag.
It just creates 2 db files.
Android 5.0.1.
Thanks.
Are you using Baidu browser? Cuz that's probably why it is there. Or any other app that has been created by them.
No, not using that.
No Baidu apps at all? Then it must be some adware.
I had it too. Just did a factory reset to wipe the internal storage and it's gone. Lol. Maybe u can backup ur stuff and try that for the last resort.
Confirm, no baidu apps.
I had done that reset and the folder is still there. It must be some app process, but which app?
No solution to catch app?
Install an antivirus software and do a scan. That might be adware.
Scan by Avast! doesn't report anything, finished with 0 errors.
Hi,
Problem found. That was Samsung Vitamins program creating that folder, after disable it and test no more Baidu folder.
So I rooted by Galaxy S5 SM-G900V running 4.4.4. (please be specific, Im new to this). My device is ALREADY rooted and 100% confirmed, as I used root checker.
And now everytime I open gallery or do certain things, It tells me "Unfortunately, Context Service has stopped working."
I read on a thread you can Rename or replace the ContextService.apk file located under /system/priv-app to fix it, So where do I get a non corrupt copy? And how do I access the /system/priv-app area? Connect to a pc?
Also, wouldnt replacing with a non corrupt version be more important that renaming it and no longer working? Do we not need it?
update
So I downloaded Root Explorer app to find that "/system/priv-app area" and nothing. I can not find any "system" file or Priv-app area.
Thanks
You need to root your device. For file explorer try ES File Explorer for root browsing.
already rooted

My Device IS rooted already.
Hello guys. I will get straight into it.
I have used CF auto root to root my Samsung S5 Neo G930F. It has rooted successfully and I was able to use multiple root required apps. As I am a big fan of Pokemon Go, but a fan whom has very little time I hoped that I can use my rooted device for my advantage.
So my problem is that whenever I try to move ANY downloaded app to system/app using Lucky Patcher, after the phone reboots the app is gone, the icon is no-where found in the list, using ES File Explorer, using the root explorer the com. file is no-where found either, not in the data/app folder neither in the system/app folder.
I have tried various different ways to transfer the application to system/app. I have tried Lucky patcher, by installing the application from google play and using lucky patcher to move it into system/app. I have tried using some other google play store app, system/app mover root, I have tried installing the app throught lucky patcher straight onto system/app, I have tried cutting the com. folder from data/app and pasting it into system/app but by doing that the application did not even start up. After reboot the app was gone. I have also ensured that the system partition is set to ReadWrite before executing any of the above actions.
Just in case anyone asks, I have followed numerous tutorials, none of which have helped. I was able to also root my sony Xperia Z2, and install the GPS Spoofer and set it as a system/app without any problems.
Any help would be appreciated.
Thank You!
