How to add SDK files manually that needs a package.xml in android studio?

I have just installed Android studio and it needs to download some SDK files. But my internet connection is slow and the download keeps failing.
so I took the links and downloaded all SDK files manually with my download manager and then I unzipped them and put them in SDK path which in my case is:
C:\Users\USERNAME\AppData\Local\Android\Sdk
the problem is when I open Android studio it still downloads these SDK files. I don't know how to tell android studio that these files are already downloaded. Can anyone solve this?
Android Studio that I am using is version 4.0.0.
Check the images for more information:
And when I click the edit:
And after clicking next:

I finally figured it out. the SDK manager add a package.xml with some details after it download the sdk components and unzipped them. so manually unzipping sdk components to sdk folder won't work because sdk manager won't know if the component is already installed and it tries to download it again. (note: not all sdk components need a package.xml and work properly if you manually unzip them into sdk folder.)
Solution:
1- you should download the components manually with a download manager if you don't have the sdk components zip files. you can get the files link from the sdk download log:
2- wait until the downloading of that specific component fails. like in the picture
3- then the sdk manager start the download of another component, in the meantime you should go to sdk folder and inside .temp folder you would see folders with names like packageOperation followed by a number. in each one of this folders is a sdk component download file (in our case failed download) that probably has an extension of .asdownload.
4- Delete the file with .asdownload and paste your fully downloaded zip file.
5- you can follow the steps for every sdk component. at the end the sdk manager will give you a retry option if there was any failed downloads. click retry, this time the sdk manager won't download the sdk files that failed (because of the sdk zip files that we manually pasted inside packageOperation folders) and it automatically installs them.
and that's it. you should see sdk components finishes successfully.

In Android Studio Settings -> Appearance & Behaviour -> System Settings -> Android SDK.
In this, there will an option for Android SDK location. Choose the directory of your Android SDK & it will use the SDK from that location.
Note:
I am using 4.1 canary 10.
In case, you don't find the setting in the above-mentioned path, open Android Studio, and search for SDK.

Android SDK >> Android SDK location >> Edit >>(C:\Users\USERNAME\AppData\Local\Android\Sdk)
then click Apply >> Ok

Can't find SDK folder inside Android studio path, and SDK manager not opening

I have installed Android Studio for the millionth time but when i go to C:\Program Files\Android\Android Studio , i can't find any folder named "SDK" , can't find it any where on the computer either.
Also, the SDK manager doesn't open, which i guess is a problem linked to the first one.

If you have downloaded the AS + SDK bundle:
Assuming the defaults were left unchanged, you will find the SDK in
C:\Users\%USERNAME%\AppData\Local\Android
If it is missing at this location, one of the following reasons apply: you have chosen a custom location, you missed to install the SDK at all, or (unlikely) they have changed the default install location.
Note #1: the AppData directory is hidden by default. If you have a standard Windows configuration, the C:\ path above should work "as is" (hit Win + R -> paste the path -> Enter).
Note #2: you will never find the SDK in the Android Studio directory unless you have explicitly put it in there. The reason is that those directories might be deleted after installing a newer version of Android Studio and you would have to re-install the SDK as well.
If you have retrieved the standalone SDK by some other means:
The SDK location may vary (from my experience), however (assuming the default configuration) you will most likely find it in C:\Program Files\Android or C:\Users\%USERNAME%

Tools > Android > SDK Manager > there you'll see the path to SDK

If you don't have it at C:\Users\%USERNAME%\AppData\Local\Android (this is where most people have it) than it is possible you don't have it installed. Go to Tools > Android > SDK Manager and then click on "Android SDK." On the top of the SDK Manager it will list the SDK Location. Click edit. If you don't have Android SDK installed, it will give you the option to install it in certain location. Install it, and Android Studio should work!

SDK folder by defalut is in C:\Users\<user-name>\AppData\Local\Android. And the AppData folder is hidden in windows. Enable show hidden files in folder option, and give a look inside that.

Make sure all the folders are visible.
click start>control panel>Appearance and Personalization>Show hidden files and folders then click "Show hidden files, folders and drives"
The file should be in C:\Users\Username\AppData\Local\Android as mentioned above. otherwise you can check by opening Android SDK Manager - top left under SDK path.

If SDK folder is present in system, one can find in C:\Users\%USERNAME%\AppData\Local\Android
If Android/SDK folder is not found
Once done with downloading and installing Android Studio, you need to launch studio.
On launching Android studio for the first time, we get option to download further more components, in that we have SDK.
On downloading components one can find SDK under Appdata (C:\Users\%USERNAME%\AppData\Local\Android)

I had to open Android studio and go through the wizard. Android studio will install the SDK for you.

If your are using android studio go to file >> project structure on the left pane press on SDK location . you will find the path where your sdk is located

When you install the android studio just by downloading from https://developer.android.com/studio/install.html sometimes sdk folder will not get appear in C:\Users\home\AppData\Local\Android Location..
But to set the android studio we need to set the path for android on this location.
So simply
1) start the android setup.
2) follow the instruction and android studio will automatically download the sdk folder by itself. (it will show the window like "Downloading Components").
After completing that installation check the above path again.
sdk folder will get appear now.

I faced the same issue. And I am able to resolve it by uninstalling the previous version I had, and removing the Android studio projects and reinstalling it.
And then go to Settings-> Android Studio -> Click on edit, to specify studio location, it will recognize the requask you if you would like to download sdk,

So I was trying to root one of my old phones and process required Android SDK. When I searched Android SDK, all i could do was download and install Android Studio. Everything went fine and smooth, till I tried to look for SDK in installation. I could not find it under Android Studio installation. But after a little search on Google and Android Studio configuration on my computer, I was able to find it at
C:\Users\username\Android\sdk
I hope that helps.

C:\Users\*********\AppData\Local\Android\Sdk
Check whether the USERNAME is correct, for me a new USERNAME got created with my proxy extension.

I found it in /Users//Library/Android/sdk

For me it was :
C:\Users\{your-user-name}\AppData\Local\Android\Sdk\tools\bin
Hope it helps!

After installation if you get a message about Proxy, it means that you're probably behind a firewall. You can create a new Outgoing firewall rule to include it. Add this to Allow:
C:\Program Files\Android\Android Studio\bin\studio64.exe
It will then download required SDK components
Once that's done, SDK will be in:
C:\Users\your_user_name\AppData\Local\Android\Sdk

For anyone who really can't find the SDK, you can manually download it from android studio.
File => Settings => Appearance & Behavior => System Settings => Android SDK
If you do not have a SDK (or did not select the right folder), you will be asked to select the SDK version and the folder where the SDK will be installed.
This is how I fixed by SDK not found problem.

System: Ubuntu 16.04 LTS, yet you can try these steps in accordance to your respective systems.
If there is an SDK file present, it should be most likely found at /home/USERNAME/Android/sdk
USERNAME is to be replaced by your username
If there is none, check the specified sdk path for the project in android studio.
File > Project Structure > sdk path
The sdk directory should be present in the specified path. In case, it is not there, open the file:
PROJECT_DIRECTORY/android/local.properties
PROJECT_DIRECTORY needs to be replaced by your project name.
If the file is not there, create it.
Then add the following line depending on where you find the sdk directory.
If sdk is there at /home/USERNAME/Android/:
add the line: sdk.dir = /home/tanya/Android/sdk
If sdk is not there at /home/USERNAME/Android/:
add the line: sdk.dir = /home/tanya/Android/
If the path specified for sdk directory in 'Project Structure' is entirely different and the sdk directory is present at the specified location,
add the line: sdk.dir = SPECIFIED_SDK_PATH
Add the specified sdk path in place of SPECIFIED_SDK_PATH

Failed to execute tools\android.bat: solution

When I try to open up the SDK Manager in eclipse it says opening shortly, but never opens. I've tried to open the exe file but it displays an error message saying:
Failed to execute tools\android:bat the system cannot find the file specified
My path environment variable leads it to the tools folder.
This is the path:
C:\Users\Shan\Documents\Computer Science - YEAR 2\Android App Development\adt-bundle-windows-x86-20130917\sdk\tools

In my case the Tools directory just disappear.
..\sdk\tools
To solve it:
1) Just go to SDK zip -> adt-bundle-windows-x86_64-20131030.zip
2) Unzip the Tools Directory only.
3) copy it under ../sdk/

I had a similar problem today. Press the Windows button and Search for android.bat(in the search programs and files text field)
Then copy the file to your android SDK folder (C:\Users\Shan\Documents\Computer Science - YEAR 2\Android App Development\adt-bundle-windows-x86-20130917\sdk\tools\).
After that don't run SDK manager but run the android.bat file.
Hope this helps

I had to move the AVD manager from /sdk/tools/lib to the root folder /sdk

Copy the AVD Manager.exe and SDK Manager.exe from
SDK_ROOT_FOLDER/tools/lib/
into
SDK_ROOT_FOLDER

I've been working with this problem for three days and finally was able to run SDK Manager by
==> Running the android.bat file as administrator
Note: I did not have to make any changes to the .bat file (such as setting the java_exe path) in order for the manager to run.
I saw this as a comment on the top answer but can't upvote yet, so confirming it here!

I cancelled an update to Android Tools and it seems there's a bug with unzipping the old (or new?) version back into {android_sdk}/tools. The zip is located in {android_sdk}/temp. Just unzip it into the right location and it should work again.

If the accepted answer doesn't help anyone, it also might be a permission issue (if the SDK is installed in Program Files (x86), for example, so try running android.bat as Administrator,

I had the same issue when updating the Android SDK Tools and SDK Platform-tools from the SDK Manager. I had to replace the tools folder with one located in a zip folder inside the temp folder.

In My case, While I installed visual studio 2015, The SDK files were missed and I am getting an error window shown below.
So I manually downloaded the tools from the following URL.
tools_r24.0.2-windows
Then extract the zip file and copy the tools folder in the following location.
C:\Program Files (x86)\Android\android-sdk
It worked for me.

I think current Android SDK only works with JDK x86 version. I search so much but when installed JDK x86 version Android SDK manager worked without problem.

Copy your android.bat file to C:\adt-bundle-windows-x86_64-20140702\sdk\tools folder or copy all files to C:\.

If you are seeing this error, it may be an issue with your COMSPEC environment variable.
Please see https://stackoverflow.com/a/27284746/3866013 for more details.

I had the same problem. Caused it myself because while runing Android SDK Manager i hit UNINSTALL SDK Tools.
I fixed the issue by running the installation of the Android SDK again. The installation folder had to be the same as previously. After the installation, everything was back again as it was.

This is how I solved the problem on Windows 7:
I was going to update the SDK using Android SDK Manager but android.bat was not found because previously it uninstall the older one and then installs new. In my case my SDK Update was interrupted i.e. in other words, could not install after the SDK Manager uninstalled the tools, so my machine was not able to find android.bat. What I did was just downloaded the standalone SDK tools to the same folder where my SDK were from :
http://developer.android.com/sdk/index.html#Other

https://developer.android.com/sdk/index.html#Other
Here are two options for downloading the Android SDK for Windows users. One in recommended option and the other is .zip file. Zip file worked well.
Another option may also work. Try searching android.bat with windows search engine. If you find the one, copy it and paste in SDK tools folder.

open Sdk Manager.exe, then i deleted first Android Sdk tools, so, I also appeared such a mistake, then I downloaded installer_r24.3.2-windows.exe, installing, copy C:\Users\Super Man\AppData\Local\Android\android-sdk\tools folder to my Sdk path,run My Sdk Path\android.bat ,ok!!

I did the following :
I created a folder SDK right below my C-drive
I unzipped tools_r25.2.3-windows.zip to C:\SDK
I moved SDK Manager.exe from C:\SDK\tools\lib to C:\SDK
I first ran SDK Manager.exe in 'normal mode',but this gave me the error, but when I ran SDK Manager.exe as ADMINISTRATOR it didn't return the error.

The reg command exists but for unknown reason my path variable was corrupted during some installation.
So some basic element were missing:
C:\WINDOWS\system32;
C:\WINDOWS;
C:\WINDOWS\System32\Wbem

Android compatibility library (Android support) install problems

I am trying to install the Android Support package (previously known as the Android Compatibility Library, I think) using the SDK Manager, but it keeps (silently) failing to install.
According the the documentation, it should install to my /extras/ directory, but after what looks to be a successful download and installation from the SDK, the directory is empty. There are no errors in the SDK Manager log, and the module says that it is installed in the list of "extra" packages......but it is not!
Has anyone else had any experience of this?
I'm using Wnidows Vista + Eclipse.
Cheers,
Chris

So - couldn't figure out why the SDK Manager won't install it, but I did find this link on StackOverflow that explains how to manually download packages from the Google repository (this is explained in an external blog here)
This means that I can at least download the .zip file and install it manually!

Try to run the SDK as admin from the location you had installed.

Alternatively, you could just not use eclipse at all and add the .jar to your build path manually.
Create a directory called "libs" in your project explorer.
Drag and drop the support package file (.jar) into your new "libs" directory.
Right click the .jar file and click "add to build path".
And there you have it :)

platform-tools\aapt.exe directory missing in android SDK

I'm trying to get 'hello world' working on the Android SDK with Eclipse. I'm following this tutorial step by step:
http://developer.android.com/resources/tutorials/hello-world.html
but i'm returned the error "Error executing aapt. Please check aapt is present at C:\android-sdk-windows\platform-tools\aapt.exe"
For some reason, the "platform-tools" folder does not exist under my installation. In its place I find "platforms" and "tools". Presumably, my SDK version is different to that used in the tutorial.
I can't work out what i need to change or update. Can someone please point me in the correct direction?
Thank you

Totally agree with izzy, but other times (usually on 64 bit OS machines or with multiple android platforms) when you install the latest SDK version the folder platform-tools had missing the "appt.exe".
To solve this you need to search on *android-sdk\build-tools* folder and subfolders like \build-tools\17.0.0 in my case, and you will find aapt.exe, other necesary files and lib folder, just copy it everything to android-sdk\platform-tools and it will be done.

sometimes you may get the error that it can not install because it can not create the temp folder to install the tools. You simply just need to run the SDK manager as administrator and this will allow it to all work out.

if we will face appt.exe issue (could not found) just Follow the below steps:
1. Just Read It(https://developer.android.com/studio/command-line/aapt2)
Navigate to (ctrl+find and search) com.android.tools.build > then go to aapt2 from this url (https://dl.google.com/dl/android/maven2/index.html)
Insert the version name you copied into the following URL and specify your
target operating system: https://dl.google.com/dl/android/maven2/com/android/tools/build/aapt2/aapt2-version/aapt2-aapt2-version-[windows | linux | osx].jar
For example, to download version 3.2.0-alpha18-4804415 for Windows,
you would use: https://dl.google.com/dl/android/maven2/com/android/tools/build/aapt2/3.2.0-alpha18-4804415/aapt2-3.2.0-alpha18-4804415-windows.jar
Extract the jar file, Change the name aapt2.exe to apt.exe
Copy and paste into your android-sdk -> platform-tools
Run the program, Issue will be get resolved
Note: Means you have to download and set the aapt.exe path in System Environment Variable

*What version of the SDK are you running? (1.5_r2 or something?)*
I would suggest updating your SDK and be done with it ;)
You can do so trough the "Android SDK and AVD Manager".
Eclipse:
menu->window->"Android SDK and AVD Manager"
You might also want to change this setting:
menu->window->preferences->install/update->(expand)->automatic updates

Run the Android SDK Manager and be sure that you have checked and installed Tools>Android SDK Platform-tools.
I believe this package is responsible for the folder in question here.

I just found aapt.exe file in my latest Android-SDK folder (Android_SDK\build-tools\28.0.3)
You can check your latest sdk build-tools folder
or
You can search on total Android SDK folder by file name

I was able to delete my version (28.0.3) and Android Studio reinstalled it. The directory location was
C:\Users\YourUserName\AppData\Local\Android\Sdk\build-tools
