How do I install the standalone Android SDK and then add it to IntelliJ IDEA on Windows?

This is the webpage showing from where I downloaded the SDK:
On extracting the .zip folder, and opening the 'tools' folder, all I can see in an emulator.exe, mksdcard.exe and a host of .bat files (as shown below).
How do I proceed?

In IntelliJ IDEA 2017.1 and 2017.2 setting up Android SDK from scratch is complicated. I would recommended to install Android Studio and manage SDK platform there. This problem will be addressed in one of the nearest updates.
If you are brave enough, it's still possible to set it up without Android Studio using the tools\bin\sdkmanager.bat command line tool. GUI version of the SDK Manager is deprecated (no longer available in the SDK download). Standalone SDK can be downloaded here. Look below the Get just the command line tools section.
So, you will need to install at least one platform version.
First run the update to ensure you have the latest tools:
sdkmanager --update
Now you can list the packages available for installation:
sdkmanager --list
To install Android Platform: (Edit April 2022: need quotes now)
sdkmanager "platforms;android-26"
To install the current build tools version (optional):
sdkmanager "build-tools;26.0.0"
At this point you should be able to add Android SDK configuration for the installed platform version in IntelliJ IDEA like this:
You will also have access to Android SDK configuration UI where you download additional components and perform updates (just like in Android Studio):

As Karan Sharma mentioned in this post.
To add an existing SDK, you should close your project if you have any open one.
Then from the Welcome page select Configure -> Project Defaults -> Project Structure
And then from the Default Project Structure window and from the left side, select SDKs and then the plus button from the toolbar, and from the menu select Android SDK
And then give the address to the location where your Android SDK files are in, and hit OK.
Thats it!
Now it should be working for you!

You can also install the SDK in the IDEA GUI. It says in the tutorial,
If you don't have the Android SDK configured, IntelliJ IDEA will
detect this and prompt you to download it:

launch android executable and install the platforms and build-tools.

Reinstalling Android SDK (Xamarin / Visual Studio 2015)

The android-sdk install folder was corrupted during a failed update from the SDK Manager and needs to be reinstalled.
It is being used with the Xamarin Visual Studio 2015 plug in, and I'm not sure if it can be reinstalled "outside" of VS, or if there is an integrated tool that should be used.
As far as I can tell, the only hooks VS has into the SDK are the path references under Tools->Options->Xamarin->Android Settings.

You can define any Android SDK you'd like. So if you want to reinstall the Android SDK, it's as simple as deleting your current Android SDK and downloading it again and specifying the path in the Tools > Options > Xamarin > Android section.
Note: Just be cautious for other programs that might be using it such as other IDEs (Android Studio) and third party programs!

The Android SDK can be added/removed just like any other install-able component from the Modify dialog within the VS installer (JDK as well).
Manual modification is therefore somewhat of a hack now (that could lead to unforeseen consequences, which is what I'm trying to avoid).

You can only reinstall SDK, moving files for Android path.
Verify that the AVD can be run, before open Visual Studio.
Can you update version, is necessary to modify path references under Tools-> Options-> Xamarin-> Android Settings

Cannot find a compatible Android SDK for compilation when running `tns platform add android`

I am following an official NativeScript tutorial and having a problem configuring my OS X environment for android development.
When running tns platform add android I receive the following error:
Cannot find a compatible Android SDK for compilation. To be able to build for Android, install Android SDK 21 or later.
The tns doctor command also returns warnings on android-sdk issues:
Cannot find a compatible Android SDK for compilation. To be able to
build for Android, install Android SDK 21 or later. Run $ android to
manage your Android SDK versions. You need to have the Android SDK
Build-tools installed on your system. You have to install version 22.
Run "android" from your command-line to install required Android Build
Tools. You need to have the latest Android Support Repository
installed on your system. Run $ android to manage the Android
Support Repository.
My android-sdk installation looks like this:
My .bash_profile also includes the followings:
export ANDROID_HOME="/usr/local/Cellar/android-sdk/24.3.4/"
export PATH="$PATH:~/npm-global/bin:/usr/local/Cellar/android-sdk/24.3.4/tools:/usr/local/Cellar/android-sdk/24.3.4/platform-tools"
Should I go further and try setting system-wide environment variables - not just for the .bash_profile? Also, it is possible that I missed something from the setup process...
Any tip on how I could debug this situation (commands, config files etc.) would be great, thank you!

Alright, so you need to make sure of following:
Make sure you have API 22 installed.
Make sure you you have Android SDK Build Tools 22.x.x installed. (Yes,
specifically 22.x.x)
Make sure you have Android support repository installed. (You can
find it under Extras section in Android SDK Manager)
Once you have performed steps mentioned above, run tns doctor again and you should see No issues were detected message.

This is because of sudo. The root user has no ANDROID_HOME set.

For Windows User:
Run 'android update sdk' from command line
Select Android 5.1.1(API22)
Select Tools folder
Select Extras and click on Install.
ps:- adding this answer, so that if any one land on this page can see it.

Check the ANDROID_HOME is ok
Install the API 22 + ion the Extras > Android Support Repository
Run the following
tns platform remove android
tns platform add android#next
Run
tns run android
then it should be OK

I solve this problem installing Android Support Repository from Extras.

updating SDK in AndroidStudio >> Preferenceswould help

on my windows 10 machine I had to open file explorer right click on this pc and go to properties on the left hand side I had to go to advanced settings. At the bottom I click environment variables then on the android_home variable I clicked edit then pointed it to this path on my machine where the sdk was installed
C:\Program Files (x86)\Android\android-sdk

This answer is on a Linux, not OSX, platform. However, since this is the SO that appears most often for the listed error, I'll share a recent fix that worked for me.
If you have done all of the above and are still getting the error, try this solution.
I am using NativeScript 8.0.2.
You will know that ANDROID_HOME and Java are configured correctly if you can run the command $ANDROID_HOME/tools/bin/sdkmanager --list. If that fails, then first check that your Java is compatible (I had to add OpenJDK 8 and change my PATH with export JAVA_HOME="/usr/lib64/jvm/java-1.8.0/")
In Android Studio, add a previous build tool version. Go to your SDK Manager > SDK Tools, tick the bottom box "Show package details", and add a previous version. In my case, 31.0.0 was the latest, and I added 30.0.3. Now run ns doctor android again and everything should pass.
Seems 31.0.0 is not yet properly recognised by Native Script.

I always got the error "✖ Cannot find a compatible Android SDK for compilation. To be able to build for Android, install Android SDK 28 or later. "
I actually had to go to the android studio settings and install the exact SDK 28 before this error went away.
Android Settings Pic

This is an updated answer, I also had the same issue:
Like all the previous pictures above, I had to install the SDK platforms, using the SDK Manager. From the main screen of Android Studio, click More Actions and choose SDK Manager. Before that I had to add the platform-tools to my PATH in Windows
%LOCALAPPDATA%\Android\Sdk\platform-tools
That fixed my issue and the docs for setup are here.

Titunium Studio Cannot find Android SDK

I have a problem with Titanium Studio. It doesn't recognize my Android SDK installation.In the Platform->Android prefs panel, it says "No Android SDK found in the selected location"
When I first ran Titanium, it installed/updated a bunch of it's own and some Node plugins, so it's fulfilled all dependencies.
details:
OS: Windows 7 (x64)
Titanium Studio version is 3.3.1 (in %Appdata%\Roaming\Titanium Studio)
JDK build 1.8.0_31 (%Program Files (x86)%\Java\JDK)
Android SDK installation (in C:\Android-sdk)
Android SDK tools 24.0.2
Android SDK Platform Tools 21
Android SDK Build Tools
Android 4.2.2, API 17 (all children)
Android 2.3.3, API 10 (all children)
Android 2.2, API 8 (all children)
also everything inside the Extras branch
According to Titanium Compatibility Matrix, I have at least one Android SDK (4.2.2) that falls within the accepted SDK bounds for my Titanium version.

have you checked those links?
1.link 1
2.link 2
and it's better to have same architecture of java and OS.
you can also type this in command line and check if there is any specific android issue
titanium info

I don't know exactly what contributed to the solution (note that titanium CLI alwayes detected everything correctly), but here's what I've done meanwhile.
I had existing %ANDROID_SDK%, %JAVA_HOME% and the SDK's tools and platform-tools locations added to PATH from the beginning.
I Uninstalled Titanium (Studio & SDK), JDK+JRE, Node and Git.Then reinstalled JDK and Titanium.
Titanium installed node 10.13 and Git 14.sth to %programfiles(x86)%
the problem still existed. Cue another series of uninstalls.
Installed Jdk, Git, node and Titanium one-by-one.
Interstingly, this time Titanium couldn't locate Git which was installed in C:\git (it was added to PATH). So I symlikned C:\Git into %programfiles(x86)% (also linked C:\nodejs for good measure :) )
Now, I found the JDK installer only added C:\ProgramData\Oracle\Java\javapath to PATH which includes just java.exe, javaw.exe and javaws.exe. So I added %programfiles(x86)%\Java\jdk\bin to PATH.
This time, Titanium Studio worked correctly!
So, perhaps, the problem lies in Titanium Studio needing dependencies in certain locations.
(btw, before this, even though path to git.exe was in PATH, the Studio's console "couldn't find a 'bash' shell." now it does.)
hope this helps others who face the same issue.

Installing ANDROID sdk on a MAC OS X

I've been facing issues with my installation of Android sdk on my MAC.
As instructed on the google website I've followed their instructions to install
ADT Plugin
Android SDK
Eclipse platform
The installation is not on this order but as directed by the website. After installation I followed the instructions to create a .bash_profile(it was not present on my computer) and I updated it with the directory settings. Now I've installed it and set the path folder on Eclipse using the preferences->android. When I click apply and I exit I get an error stating that Android component is missing. Also to note that the android sdk->platform is supposed to contain an adb is empty.
I used this question's solution and yet I get the same error
Thank you for your input
UPDATE: It asks me to use the SDK manager to install I am unable to locate this component

It sounds like you haven't installed any actual Android SDK platforms.
Go to the tools directory of the Android SDK and run android. The Android SDK manager GUI will appear allowing you to install an android platform. Click on available packages, expand Android repository, and install the platform versions you want.
