Android Studio Not Including SDK

I'm trying to setup Android Studio on a new install of Mac OS X Yosemite. I downloaded the Android Studio Beta v0.8.14 from here: https://developer.android.com/sdk/installing/studio.html and upon launching it complained about not having an SDK (although the download page indicates it should include the SDK). I tried searching after installing for the SDK and can't find it (a few other posts indicate /Applications/Android Studio.app/sdk but that location doesn't exist). Where is the SDK installed and what is required to set it up?

Go to the SDK Manager and click Edit... next to the field for the location of the SDK. Then an "SDK Setup" window should display. There you can download the SDK.

Edit: This answer is deprecated as Android Studio seems to bundle everything since a while already.
Old answer
It seems the android-studio-bundle version is no longer available in the download page (instead there are only android-studio-ide). When you start Android Studio, it won't let you create a new projet until you configure the SDK location.
That means you have to download the SDK separately here, extract it somewhere, and configure it on Configure->Project Defaults->Project Structure. After that, the SDK Manager icon will be enabled and you can download the tools you want.

I had the same problem on Windows. After I re-installed it a few times, I found that the SDK was installed but hidden in C:\Users\<user name>\AppData\Local\Android\sdk.

Information for Windows
For some reason, which I have no time to investigate, Android seems to provide, currently, the IDE and the SDK separately, while in the Dev Webpage says the opposite.
This is the "complete" (false!) tool I have just downloaded: android-studio-ide-171.4443003-windows.exe (SDK is missing here, note the "ide" in the file name).
And this is the real complete tool I had downloaded few months ago, from the same place...: android-studio-bundle-162.3871768-windows.exe
Note that this last one has the "bundle" in the file name.
Please, download the bundle (IDE+SDK) from here:
https://dl.google.com/dl/android/studio/install/2.3.1.0/android-studio-bundle-162.3871768-windows.exe?hl=ko
I want to suppose (¿?) that similar link you can find for Linux or macOS just Googling for it.
Hope this helps!

It worked like this for me
Downloaded the Android Studio
Install Android Studio
Open Android Studio after installation.
You will get a dialog box to import settings if you already have Intellij installed on your machine. Say "Do not Import". Otherwise continue to next step.
It will ask you in the dialog box to pre-configure such as theme, path etc.
Just click next next...and then Finish. You will see the SDK tool will start downloading.
After installation is finished. You can find it in this path: C:\Users\<user name>\AppData\Local\Android\sdk

If you have ever installed Android Studio before and then removed it, it won't reinstall the SDK automatically (speculation: some Windows setting somewhere).
The solution is starting Android Studio and then
File -> Manage IDE Settings -> Restore Default Settings
This will wipe any custom settings you don't have at this point and trigger the SDK install

What Pablo wrote is misleading.
This is the "complete" (false!) tool I have just downloaded:
android-studio-ide-171.4443003-windows.exe (SDK is missing here, note
the "ide" in the file name).
Yes, it is IDE only, but after you install this IDE and first time run it, SDK will be downloaded automatically. So there is no need to download some outdated bundles. Just use default "green button" on https://developer.android.com/studio/index.html

I'm using Ubuntu, and had previously installed Android Studio. It was using too much space, so I deleted it. Now when I downloaded it and started ./studio.sh, it found my previous installation configuration directory and asked to import from there. I did, and then this problem occurred.
I put the directory .Android Studio 3.3 in the trash and restarted ./studio.sh, and it imported the SDK automatically for me. That was good, because I couldn't find it where it was supposed to be according to the dialog box. The 3.3 above is from the version of Android Studio I was installing.

in my case, my country is forbidden from google, and my PC's time zone was set by my counrty.
after I change my timezone to another country my problem solved and android studio download SDK and nkd easily

Re-install studio. If ANDROID_HOME is set to custom location then it will install sdk there else it will install SDK in C:\Users<user name>\AppData\Local\Android\sdk

Note:this is a temporary fix
If you have Eclipse then you can use that SDK for emulation.
Just run the sdk manager and emulate a version of android. Then while you are asking for emulating something ie while running code it will show your emulator as online and you can even use it.
Hope this helps you.
All the Best...

How to install older Android SDK in Eclipse

I'm working at the moment at a simple app in eclipse for android. Just receiving and sending data, and using the camera API.
I've set the minSDKversion to 8, because I think that has the widest user base. But at the beginning of the project eclipse was asking me which target SDK version I would use, and because I had just one installed (the latest 4.0.3) I've took this.
Now I'm asking me if it wouldn't be wiser to install a lower SDK, like Android 2.2, because it would be not that big (compared to the 4.0.3) and my app would not have included all the fancy new features, which are not used in any way?! Or is this complete nonsense I'm talking here, and just should take my 4.0.3 SDK? When not, how can I install a lower version? Help -> SDK Manager is not showing old SDKs...

Here is a very helpful link that will probably answer your question: http://developer.android.com/sdk/installing/adding-packages.html
Basically, open up the Android SDK manager and it should give you a list of packages that you can install! From there you can choose old SDKs!

hey i faced the same issue as yours
usually while updating due to this error , it is unable to fetch the older SDKs
Failed to fetch URL https://dl-ssl.google.com/android/repository/addons_list.xml, reason: File not found
This is how you can fix it :
1) Go to Window > AndroidSDK Manager
2) select tools> options
3) set the proxy (if u r sitting behind proxy)
4) in checkboxes check Obsolete option (in Android SDK Manager)
5) go to Packages > reload (in Android SDK Manager)
This worked for me
In case you are using windows7 .
Go to Android SDK Manager location > right click > Run as Administrator

I was having a problem with this also. I tried all of the things listed in the other answers here and nothing worked. I went into Tools/Options (in the Android SDK Manager) and checked "Force https:// sources to be fetched using http://" and reloaded and the older APIs magically appeared.

if u want minSDKversion from its maxSDKversion
1.select maxSDKversion and delete all old pakages .
2. after doing it sdk manager will show all its older versions .
3. select required version and install all packages again.
:) :)
it worked for me .. just try .

Can't update installed packages in AVD Manager

I've recently tried to add packages to the SDK through the AVD Manager but I get file not found as an error when the manager goes out to find available packages. I looked at the SDK website but didn't find any resolution.
It looks like for some reason the repository path may have changed but I don't see a way to change it in the Manager.
So basically I don't see any available packages.
I wanted to install the 3.x packages to support tablets. If anyone has any idea I would appreciate any input.
thanks

I had a similar problem.
Solution:
Download the latest ADT plugin
and then the lastest SDK for your OS.
After setting up, downloading required packages should be easy.
Ensure your connection doesn't have a proxy, if it has you will required the necessary credentials.

Uninstall, download a fresh version and reinstall the entire program, it was recently updated to a new version, maybe yours missed out?

Cannot Find Google APIs for Android SDK

I've been trying to create an application that uses Google Maps and upon getting an error for "MapActivity" I searched the web and found the solution was to make my build target "Google APIs".
However, I looked in the "Android SDK and AVD Manager" in Eclipse, I could find it anywhere :(
I looked under "Third part Add-ons">"Google Inc" but it simply says "No packages found".
Any help, please?

I encountered the same problem
Go here to manually download the Google APIs.
For example, I use GoogleAPI level 8, so I download the package here
After downloading just extract the zip file to "C:\Program Files (x86)\Android\android-sdk\add-ons" and rename the directory to "google_apis-8" instead of "google_apis-8_r02".

This happened to me.
The simple fix was to update currently installed packages, which in turn updated the SDK Manager app, then after restarting, every appeared including the USB drivers.
Apparently, if the SD Manager is outdated, then you won't be able to install important thing like the USB driver.

If you're using the latest version of the SDK (ADK 14), the Google API packages should be located in the folder containing the appropriate SDK level in the SDK manager.
For example, for Android 2.2, there should be a folder called "Android 2.2 (API 8)" which should contain the SDK "SDK Platform" and additional pieces such as the Google APIs "Google APIs by Google, Inc.".

I met the same problem and it said "access is denied".
I am using 64bit win7 and the sdk tools is installed under C:\Program Files (x86)\Android\android-sdk.
I figure out that it is because the SDK manager does not have permission to the folder so the quick fix is to right click SDK manager and run it as administrator.

I found that working with the Motorola Development studio made things very easy to pick up various API levels from Google. You can find all of the download and documentation at
developer.motorola.com

Sometimes Google Server is down or return 502 error, so you cannot find any manifest file. This happened to me. The solution is to wait for a couple of minutes.

Run as Administrator did the trick from me in Windows7. SDK mgr is showing all extra google apis too after this.

I faced the same problem.
Restarting the Eclipse & SDK manager solved the problem. After Restart, all the GOOGLE API and other stuff are visible under the respective Build.
If this dont show any change, Invoke the SDK Manager.exe as ADMINISTRATOR and this will solve the problem

Try clearing your cache (Tools > Options > Clear Cache), then
reloading (Packages > Reload), and see if that helps.

If it is an old package it is possible that it is obsolete and the SDK manager wont show it by default. Go to "Packages" Tab and select "Show Obsolete Packages".

Reinstalling SDK manager and ADT solved the problem.

Android SDK and AVD Manager installation

I am new to android development.
Have tried a couple times downloading the Android SDK and ADT plugin for Eclipse
In the Android SDK and AVD manager load fine but will not load any available packages.
Show:
- Android Repository
--"Some packages were found but are not compatible updates"
In the installed it shows 1.5 to 2.3 SDK platforms.
How to I get them available.
Appreciate help.
Thanks,
Alex

You can use following step:
1. window ->
2. customize perspective ->
3. command group availability tab ->
4. on the check box android SDK and AVD manager check it ->
5. click on ok

I had the same issue. Googled arround found nothing, and gues what:
It was the a checkbox in the main Android SDK and AVD Manager.
Click: available packages
Then select: Android Repository
Then you see the "some packages were found but are not compatible updates" message, which is why you created this question.
On the bottom of the form, you can see: 4 buttons and 1 checkbox.
Make sure you Uncheck: "Display updates only" when it is unchecked, you see the whole SDK list with Android 3.2 etc.

Steps for installing Development Environment.
Download Android SDK and Install it.
Install Android API’s for different android versions. The latest version is Android 2.3.
Download and Install Eclipse Install ADT plugin.
Create AVD (Android Virtual Device) for testing the applications.
I think you did not linked your Android SDK folder with Eclipse ADT plugin. Goto Window->Preference->Android browse your Android SDK if you have installed ADT plugin.
There are many resources available online. Here is a blog post where you find some good links to resources which help you in installing Android Development Environment.
Getting Started with Android
If you still didn't able to do it. Let me know your specific problem, where you got struck.

I think there is already an answer that probably works for most people (unchecking the box), but since that did not work for this install I have on Linux Mint, this did work:
(not my website)

Basically, download the zip for the package you want and extract it to /platforms/.
