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.

moving app from data/app to system/app free app space but some app after move don't work (google goggles, setcpu, gosms, an more), so i take the apk and put into rom (oxygen 2.1.3) inside system/app folder, flashed and restarted, but they still not work
what i'm doing wrong?
sorry for bad english
I'm not an expert but I believe they also have to have the right permissions. Check what permissions the other apps in the system partition have and change the permissions on the apps you're trying to move accordingly.
Sent from my VM670 using XDA App
permissions are the same rw-r--r-- in data/app and remain rw-r--r-- in system/app
but for example when i move with rootexplorer "setcpu" at restart i have a force close and i can't use it
with "go sms" no force closes i can read messages but when i write a new one tapping on "+" to show phone book to select peope the app go in loop searching for contacts
with a widget for check credit on my phone i can't add widget if moved to system/app
i tryed other app like google goggles, google earth all give a force close at startup and not work until remove to data/app
moving ephinefrine, flash 10.3 , adobe reader, winamp and many other give no error and app still work correctly
Try extracting the apk and putting the lib.(whatever it says).so file into system / lib folder . Then put the original apk in the system / apps folder. And that should do it!

Whenever I Place new item on my SystemUI then Push Method on system > app. reboot, afterwards doesn't appear the statusbar but no error in recompiling and no force close appear.
assiming you decompiled and recompiled the apk using apktool and the mod has been done correclty
have you set the correct permissions rw-r-r
if yes then the most likely reason the status bar dissappears is due to a signature mismatch
resign the apk with zipsigner (playstore) with most likely a platform key
and its always better to flash these kind of files in cwm with system mounted

You don"t really have to reboot. You can flash a no. of systemUI.apk with this little tool. Just follow these steps :-
1. Just install it as a normal apk.
2. Open your sdcard with root explorer and create a new folder named ".tjatoer" (without quotes)
3. Now copy your systemUI.apk that you want to flash in the above folder.
4. open the hackUI apk , follow instructions and that's it !

Yup. Set it on rw-r-r. Im using Apk Multi-tool, Problem occur awhile ago. I copied the SystemUI[zip of the ROM] without any modifications/custom thing inside, decompile it. put an item on it, recompile signed(obviously). reboot, nothing problem. the only thing i'm confuse is my current systemui has a problem but dont have any idea why my current SystemUI disappear but not the SystemUI on the zip of ROM.

like I said signature mismatch - if you do a logcat of the phone booting up it will probably say something like
package com.android.systemui has no certificate at entry Androidmanifest.xml ignoring!
if the rom systemui works and yours doesnt but doesnt force close just doesnt load its most likely signature related but without a logcat who knows
I would resign the apk using a platform key with zipsigner
Best thing is to have a logcat using an app like catlog.
If it says something about signatures or certificates just follow my tutorial here on how to disable signature verification
http://forum.xda-developers.com/showthread.php?t=2725233
Than you can sign the apk and copy and change permission

Try Putting In Flashable Zip and Flash With Cwm.... It wil work
This is for those who wanted to have this function in their beast and yet no Note 5 rom is availble for their device , well smile..here you go
:good:Try at your own risk. I wont go in detail like step by step or what root explorer to use. You will have to figure it out. Im not trying to be mean but you will have to learn it =P
Your device must be rooted.
Download any rom that is made for Note 5 , custom or stock (make sure you ask for permission from the creator) , extract the folder "system/app/applicationspermissions"
and copy the folder (doesnt matter if is odex or deodexed) then paste it to your system/app/ and set the permission to the copied folder and the apk itself.
Then add the code below into your others.xml in you csc folder.
Code:
<!-- Smart Manager -->
<CscFeature_SmartManager_ConfigDashboard>dual_dashboard</CscFeature_SmartManager_ConfigDashboard>
<CscFeature_SmartManager_DisableAntiMalware>true </CscFeature_SmartManager_DisableAntiMalware>
<CscFeature_SmartManager_ConfigSubFeatures>roguepopup|autoclean|autorestart</CscFeature_SmartManager_ConfigSubFeatures>
Save , reboot and voila.
Bug
Nofitications - Block app notifications will FC.
Application Permissions - Sort by permission , will take some times to load the apps.
And it works , it does block what it offered.
Feel free to use
Thank you but nowhere i could got this foleder

can you please upload it.
Thanks in advance
