In Linux:

If you have already downloaded the android SDK but its not being found.

The problem might be that the file <code>local.properties</code> needs to be inside the same directory as <code>gradle</code> stuff for <code>gradle</code> to find it when building and running adb. 

For my react-native project using <code>gradle</code> I needed to put the <code>local.properties</code> file to <code>Myprojectname/android/</code> folder.

As I had unzipped the SDK to Downloads so I just use that path in the file with a row like this:

<pre><code>sdk.dir=/home/USER/Downloads/android-sdk-linux

I know this answer is late, but I hope it helps others.

The answer is simple. You have to just copy your <code>local.properties</code> file to the folder where project is stored and it will work like charm. But remember, it must be placed in the root folder where the project is stored.

Check, 
1. In Module settings, whether, SDK location is proper.
2. If Yes, check for local.properties file (Not the one placed inside app module, but the one placed outside the app module, at parent level). If not present add it with below lines inside it.

You just need to ask IDE to "reset" path to Android SDK.

Here is a work around for the problem when you click "Run App" (green arrow) and get the following in the Edit Configuration dialog: 

<blockquote>
 Error: Please select Android SDK
</blockquote>

In Android Studio, do:

<ol>
<li>From the menu, choose <code>File &gt; Settings</code>. </li>
<li>In the settings dialog, go to <code>Appearance &amp; Behavior &gt; System Settings &gt; Android SDK</code>.</li>
<li>Look at the top for Android SDK Location, and click the <code>Edit</code> button</li>
<li>Hit Next, Next, Finish to accept the defaults</li>
</ol>

This seems to save away the SDK location - even though nothing has changed - into some internal location. I inspected the <code>.idea</code> and <code>.gradle</code> folders but didn't see what Studio did to change a config file - but now I can run the app.

And to summarize the previous fixes - these are normally OK for a repo without build problems:

<blockquote>
 <ul>
 <li>local.properties file is copied into the root folder by Studio.</li>
 <li>The path in the local.properties file has the correct path to the android SDK - in my case it is <code>sdk.dir=C:\\android\\sdk</code>
 (note that this path has a different format - Studio should write this file for you based on the Text Entry field in the Android SDK Settings dialog)</li>
 <li>settings.gradle file is present in the repo - and references the application folder (typically :app)</li>
 </ul>

Please follow below steps it work's for me:

<ul>
<li>Go to your react-native Project then go to android directory
Create a file with following name:</li>
</ul>

<blockquote>
 local.properties
</blockquote>

<ul>
<li>Open the file and paste your Android SDK path like below:</li>
</ul>

For windows users:

<pre><code>sdk.dir=C:\\Users\\UserName\\AppData\\Local\\Android\\sdk
</code></pre>

Replace UserName with your pc user name . Also make sure the folder is sdk or Sdk. In my case my computer user name is Zahid so the path look like:

<pre><code>sdk.dir=C:\\Users\\Zahid\\AppData\\Local\\Android\\sdk
</code></pre>

For Mac users:

<pre><code>sdk.dir = /Users/USERNAME/Library/Android/sdk
</code></pre>

Where USERNAME is your OSX username.

For Linux (Ubuntu) users:

<pre><code>sdk.dir = /home/USERNAME/Android/Sdk
</code></pre>

Where USERNAME is your linux username(Linux paths are case-sensitive: make sure the case of <code>S</code> in <code>Sdk</code> matches)

In case if this doesn't work, add ANDROID_HOME variable in "Environment Variables" as <code>C:\Users\USER\AppData\Local\Android\Sdk</code>

I just faced the issue when I cloned my repo from Github and ran <code>./gradlew clean assembleDebug</code>. I confirm I have ANDROID_HOME in my .bashrc file.

So, I imported the project into Android Studio. Noticed that extension of my settings.gradle file is <code>.kts</code>, <code>settings.gradle.kts</code>. When I am done with import then I ran <code>./gradlew clean assembleDebug</code> and didn't get any issue.

If you have this problem when you pull a react-native project, you just need to open the android project with Android Studio. Everything you need will be automatically created.

<ul>
<li>Open Android Studio</li>
<li>File -> Open</li>
<li>Choose the <code>android</code> folder under your react-native project folder</li>
<li>Wait for AndroidStudio to complete setup</li>
<li>You can now close Android Studio</li>
</ul>

OR

If you have installed the <a href="https://stackoverflow.com/a/48266060/6155481">AndroidStudio command line launcher</a>:

<ul>
<li>Run this in your react-native root folder</li>
</ul>

<pre><code>studio android/

go to this pc -> properties -> advanced system settings -> environment variables -> 
then in system variable create new variable with name ANDROID_SDK_ROOT and value C:\Users{USERNAME(Replace it with your username}\AppData\Local\Android\Sdk

then close cmd and restart it should work.

I came across the same issue but a little bit different error message is 

<blockquote>
 SDK location not found. Define location with an ANDROID_SDK_ROOT
 environment variable or by setting the sdk.dir path in your project's
 local properties file at "xxx"
</blockquote>

MAC &amp; ReactNative

Add <code>local.properties</code>

<ol>
<li>Find your Android SDK location

<pre><code>/Users/yourMacUserName/Library/Android/sdk
</code></pre></li>
<li>Create <code>local.properties</code> under <code>rootProject/android/local.properties</code>.</li>
<li>Add sdk path into it

<pre><code>sdk.dir = /Users/yourMacUserName/Library/Android/sdk
</code></pre></li>
</ol>

This normally works, but if you are working in a team with other team members, then <code>yourMacUserName</code> is different.

OR

Set <code>ANDROID_SDK_ROOT</code> variable

<ol>
<li>Edit your <code>~/.zshrc</code> or <code>~/.bashrc</code> or ...</li>
<li>Add SDK path:

<pre><code>export ANDROID_SDK_ROOT=$HOME/Library/Android/sdk
</code></pre></li>
<li>Open a new terminal tab or <code>source ~/.zshrc</code></li>
<li><code>echo $ANDROID_SDK_ROOT</code> to test the print correct SDK path.</li>
</ol>

Alternatively, you also can add your path
<code>export PATH=${PATH}:$ANDROID_SDK_ROOT/tools:$ANDROID_SDK_ROOT/platform-tools</code> 
to use some useful commands.

For me the problem was that I haven't created any virtual devices after fresh installation of android studio. So, expo kept complaining vaguely about the sdk location while the main issue was the missing virtual devices. Hope this helps somebody in the future, had me searching for a couple of hours.

In my case i had the error sdk location not found

What i did:
I went to the cloned project from git 
opened the project directory
opened the app directory inside the project
copied the local.properties file
and then pasted it in the project directory
Then it worked

blocks|key|143271|text|对我来说，这个问题是由于打开克隆项目时使用“打开现有项目”而不是“导入”造成的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|143272|下载的工程中已经存在setting.gradle文件。然而，Android+Studio不会使用“打开现有项目”选项来获取它，只有"import“会强制Android+Studio解释整个项目设置。|143273|在M.Palsich的回答中也隐含地提到了同样的想法。|143274|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

For me, this problem is caused by opening the cloned project with &quot;open an existing project&quot; instead of &quot;import&quot;.
The file &quot;setting.gradle&quot; already exists in the downloaded project. However, it doesn't get picked up by Android Studio using &quot;open an existing project&quot; option, only &quot;import&quot; will impose Android Studio to interpret the whole project settings.
The same idea has been mentioned implicitly in M.Palsich's answer.

To fix the issue locally on MacOS I just went to <code>File &gt; Project Structure...</code> in Android Studio and it fixed it automatically.
To fix the issue in the git I executed the following commands in the project root directory:
<pre><code>echo -e &quot;\nlocal.properties&quot; &gt;&gt; .gitignore
git add .gitignore
git rm local.properties --cached
git commit -m &quot;Removed local.properties from the git&quot;
</code></pre>

blocks|key|145732|text|正如我所检查的，当他们在Android目录中创建local.properties文件并写入路径时，仍然会出现错误。你得到错误的原因是因为在写入路径中有拼写错误。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|145733|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

As I checked that some are still getting error when they create local.properties file in Android directory and writes the path.
The reason you're getting error is because there's spelling mistake in writing path.

blocks|key|2719064|text|可能有两种不同的可能性：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2719065|1)。local.properites文件中的SDK位置不正确。|2719066|2)。或者文件丢失，如果你克隆了一个项目，可能会发生这种情况，所以只需在Gradle+Scripts文件夹下创建一个local.properites文件，然后设置sdk路径。|2719067|如下所示设置正确的sdk路径：|2719068|sdk.dir=YOUR_PATH_TO_THE_SDK|code-block|syntax|javascript|2719069|对于mac用户，路径应为：|2719070|/Users/USER_NAME/Library/Android/sdk|2719071|对于windows用户，路径应为：|2719072|c:\Users\USER_NAME\AppData\Local\Android\Sdk+|2719073|entityMap^0|0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|X|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|Y|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|Z|8|@]|9|@]|A|$]]|$1|H|3|I|5|J|7|10|8|@]|9|@]|A|$K|L]]|$1|M|3|N|5|6|7|11|8|@]|9|@]|A|$]]|$1|O|3|P|5|J|7|12|8|@]|9|@]|A|$K|L]]|$1|Q|3|R|5|6|7|13|8|@]|9|@]|A|$]]|$1|S|3|T|5|J|7|14|8|@]|9|@]|A|$K|L]]|$1|U|3|-4|5|6|7|15|8|@]|9|@]|A|$]]]|V|$]]

There can be two different possibilities :
1). Either you SDK location is incorrect in local.properites file.
2). Or the file is missing, this can happen if you have cloned a project, so just create a local.properites file under Gradle Scripts foler, and then set up the sdk path.
Set up the correct sdk path like this :
<pre><code>sdk.dir=YOUR_PATH_TO_THE_SDK
</code></pre>
For mac users the path should be:
<pre><code>/Users/USER_NAME/Library/Android/sdk
</code></pre>
For windows users the path should be:
<pre><code>c:\Users\USER_NAME\AppData\Local\Android\Sdk 
</code></pre>

blocks|key|144446|text|我遇到过这样一种情况:我已经设置了local.properties文件，但仍然收到这个错误。结果是，如果您的项目有子模块，则还必须将local.properties复制到子模块文件夹中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|144447|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I had a situation where I already had the local.properties file set up but I was still getting this error. Turns out, if your project has a submodule, you have to copy the local.properties into the submodule folder as well.

blocks|key|2931831|text|打开Android+Studio，进入文件菜单，选择文件结构，然后指定一个带有你在“compileSdkVersion+/build.gradle”文件中定义的compileSdkVersion或targetSdkVersion的SDK。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2931832|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Open Android Studio, go to the File menu and select File Structure and specify an SDK with compileSdkVersion or targetSdkVersion that you defined in the &quot;app/build.gradle&quot; file.

<ul>
<li>first scenario :-</li>
</ul>
<hr />
look for local.properties file in your project and
set sdk path.
<ul>
<li>second scenario :-</li>
</ul>
<hr />
if you you don't have one then copy from other project and set it according your sdk path .

blocks|key|144493|text|我用文件/无效缓存/重启解决了这个问题，然后点击Set+SDK...当出现错误提示时。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|144494|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I solved that issue with File/Invalide cache/Restart, then click on Set SDK.... when prompted by the error.

I recently tried to import sample Android games I downloaded from Google's developer website. After importing them into Android Studio, I'm getting the following error:

<blockquote>
 Error: SDK location not found. Define location with <code>sdk.dir</code> in the local.properties file or with an <code>ANDROID_HOME</code> environment variable.
</blockquote>

What is this? I want to run the sample programs from Android Studio.

SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable

最近，我试着导入我从谷歌开发者网站下载的Android游戏样本。在将它们导入Android Studio后，我得到了以下错误：错误:找不到SDK位置。使用local.properties文件中的sdk.dir或ANDROID_HOME环境变量定义位置。这是什么？我想运行Android Studio中的示例程序。
