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 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   export ANDROID HOME  pathtobundle adt-bundle-linux-x86 64-20130729 sdk  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   cd pathtobundle wget http   dl google com android adt adt-bundle-linux-x86 64-20130729 zip unzip   zip  As someone else said  you may need to run the SDK Manager to install the desired packages before running Studio

You can solve the problem changing the compileSdkVersion in the Grandle build file from 18 to wtever SDK is installed       BUTTTTT   If you are trying to goin back in SDK versions like 18 to 17  You can not use the feature available in 18 or 18  If you are migrating your project  Eclipse to Android Studio   Then off course you Don t have build gradle file in your Existed Eclipse project    So  the only solution is to ensure the SDK version installed or not  you are targeting to   If not then install   Error Cause  failed to find target with hash string  android-19  in  C  Users setia AppData Local Android sdk

What worked for me in Android Studio  0 8 1      Right click on project name and open Module Settings Verify SDK Locations  Verify Gradle and Plugin Versions  Review the error message hints for the proper version to use   On the app Module set the Compile SDK Version to android-L  latest  Set the Build Tools version to largest available value  in my case 20 0 0     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

Target with hash string  android-18  is corresponding to the SDK level 18  You need to install SDK 18 from SDK manager

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  http   schinagl priv at nt hardlinkshellext linkshellextension html  just to take the tedium out of creating symbolic links

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

This will also happen if you have written compileSdkVersion   22 e g   as used in the  new new  Android build system  instead of compileSdkVersion 22

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 solved the problem by changing the compileSdkVersion in the Gradle build file from 18 to 17   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
