I solved the problem by changing the <code>compileSdkVersion</code> in the Gradle.build file from 18 to 17.

<pre><code>buildscript {
 repositories {
 mavenCentral()
 }
 dependencies {
 classpath 'com.android.tools.build:gradle:0.5.+'
 }
}
apply plugin: 'android'

repositories {
 mavenCentral()
}

android {
 compileSdkVersion 17
 buildToolsVersion "17.0.0"

 defaultConfig {
 minSdkVersion 10
 targetSdkVersion 18
 }
}

dependencies {
 compile 'com.android.support:support-v4:13.0.+'
}
</code></pre>

I think you might not have the Android-18 sdk installed. Go to Tools > Android > SDK Manager and check to see if Android 4.3 (API 18) is installed.

I had the same problem when trying out Android Studio. I already had projects running on the ADT under SDK 18. No need to hack the manifest files.
Fixed by:
<blockquote>
export ANDROID_HOME= pathtobundle/adt-bundle-linux-x86_64-20130729/sdk
</blockquote>
If you don't have the ADT installed, and just want the SDK, it seems like a good solution is to install everything and then point Android Studio to the just the packaged SDK.
<blockquote>
cd pathtobundle
wget <a href="http://dl.google.com/android/adt/adt-bundle-linux-x86_64-20130729.zip" rel="nofollow noreferrer">http://dl.google.com/android/adt/adt-bundle-linux-x86_64-20130729.zip</a>
unzip *.zip
</blockquote>
As someone else said, you may need to run the SDK Manager to install the desired packages before running Studio.

blocks|key|178656|text|检查Studio项目中的local.properties文件。如果您在pre-studio时代设置/配置了以前的android+sdk，则可能是属性sdk.dir指向了错误的文件夹。这就是我的解决方案。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|178657|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|$]]

Check the local.properties file in your Studio Project. Chances are that the property sdk.dir points to the wrong folder if you had set/configured a previous android sdk from pre-studio era. 
This was the solution in my case.

What worked for me in Android Studio (0.8.1): 

<ol>
<li>Right click on project name and open Module Settings</li>
<li>Verify SDK Locations <img src="https://i.stack.imgur.com/UIqN7.png" alt="SDK"></li>
<li>Verify Gradle and Plugin Versions (Review the error message hints
for the proper version to use) <img src="https://i.stack.imgur.com/OrVEI.png" alt="Gradke"></li>
<li>On the app Module set the Compile SDK Version to android-L (latest)</li>
<li>Set the Build Tools version to largest available value (in my case
20.0.0) <img src="https://i.stack.imgur.com/9t2vG.png" alt="Build"></li>
</ol>

These changes via the UI make the equivalent changes represented in other answers but is a better way to proceed because on close, all appropriate files (current and future) will be updated automatically (which is helpful when confronted by the many places where issues can occur).

NB: It is very important to review the Event Log and note that Android Studio provides helpful messages on alternative ways to resolve such issues.

I've had a similar problem occurr when I had both Eclipse, Android Studio and the standalone Android SDK installed (the problem lied where the AVD Manager couldn't find target images). I had been using Eclipse for Android development but have moved over to Android Studio, and quickly found that Android Studio couldn't find my previously created AVDs.

The problem could potentially lie in that Android Studio is looking at it's own Android SDK (found in C:\Users\username\AppData\Local\Android\android-studio\sdk) and not a previously installed standalone SDK, which I had installed at C:\adt\sdk.

Renaming Android Studio's SDK folder, in C:\Users... (only rename it, just in case things break) then creating a symbolic link between the Android Studio SDK location and a standalone Android SDK fixes this issue.

I also used the Link Shell Extension (<a href="http://schinagl.priv.at/nt/hardlinkshellext/linkshellextension.html" rel="nofollow">http://schinagl.priv.at/nt/hardlinkshellext/linkshellextension.html</a>) just to take the tedium out of creating symbolic links.

If you had the problem, opened SDK manager, installed the requested updates, returned to Android Studio and had the problem again, IT IS RECOMMENDED TO RESTART ANDROID STUDIO befor trying anything else.

Gradle will run automatically and chances are that your problem will be over. You will very possibly be told install the appropriate SDK TOOLS package, which is found in your SDK MANAGER under the second tab (sdk's are not the same as sdk tools, they are complementary packages).

You don't even need to hunt the tools package, if you click on the link under the error message, Android Studio should call SDK Manager to install the package automatically.

Restart Android Studio again and you should be up and running much faster than if you attempted workarounds.

RULE OF THUMB> restart your application before messing with options and configurations.

I have a problem with Android Studio 0.2.3.

When I run my project the build stops and appears message that says:

<blockquote>
 Gradle: Execution failed for task ':AppName:compileDebugAidl'.

although I have installed the SDK platform of Android 4.3 (API 18) and I tried to reinstall all the SDK. I've also added the <code>ANDROID_HOME</code> variable in the system variables.

What seems to be the source of this error?
