Using Gradle If you are using Gradle  you can add it as a compile dependency  Instructions  Make sure you have the Android Support Repository SDK package installed  Android Studio automatically recognizes this repository during the build process  not sure about plain IntelliJ     Add the dependency to  project  build gradle dependencies       compile  com android support appcompat-v7        Click the Sync Project with Gradle Files button    EDIT  Looks like these same instructions are on the documentation under  Adding libraries with resources - gt  Using Android Studio

Using Maven  First of all you should install android libraries to your local maven repository using Maven Android SDK Deployer  Then you can add dependency to your pom like this        lt dependency gt           lt groupId gt android support lt  groupId gt           lt artifactId gt compatibility-v7-appcompat lt  artifactId gt           lt version gt   compatibility version  lt  version gt           lt type gt apklib lt  type gt       lt  dependency gt        lt dependency gt           lt groupId gt android support lt  groupId gt           lt artifactId gt compatibility-v7-appcompat lt  artifactId gt           lt version gt   compatibility version  lt  version gt           lt type gt jar lt  type gt       lt  dependency gt

Another solution for maven  and a better solution  for me at least  is to use the maven repository included in the local android SDK  To do this  just add a new repository into your pom pointing at the local android SDK    lt repository gt       lt id gt android-support lt  id gt       lt url gt file     env ANDROID HOME  extras android m2repository lt  url gt   lt  repository gt    After adding this repository you can add the standard Google dependency like this    lt dependency gt       lt groupId gt com android support lt  groupId gt       lt artifactId gt support-v13 lt  artifactId gt       lt version gt   support-v13 version  lt  version gt   lt  dependency gt    lt dependency gt       lt groupId gt com android support lt  groupId gt       lt artifactId gt appcompat-v7 lt  artifactId gt       lt version gt   appcompat-v7 version  lt  version gt       lt type gt aar lt  type gt   lt  dependency gt

As a Library Project  You should add the resources in a library project as per http   developer android com tools support-library setup html     Section   Adding libraries with resources   You then add the android-support-v7-appcompat library in your workspace and then add it as a reference to your app project    Defining all the resources in your app project will also work  but there are a lot of definitions to add and you have missed some of them   and it is not the recommended approach

This is my solution    Copy amp paste  ANDROID SDK extras android support v7 appcompat to your project ROOT Open  Project Structure  on Intellij  click  Modules  on  Project Settings   then click  appcompat -  android   make sure  Library Module  checkbox is checked  click  YOUR-PROJECT NAME  under  appcompat   remove  android-support-v4  and  android-support-v7-compat   ensure the checkbox before  appcompat  is checked  And  click  ok  to close  Project Structure  dialogue  back to the mainwindow  click  appcompat -  libs  on the top-left project area  Right-click on  android-support-v4   select menuitem  Add as library   change  Add to Module  to  Your-project   Same with  android-support-v7-compat     After doing above  intellij should be able to correctly find the android-support-XXXX modules   Good Luck

This is my solution  it is very similar to the previous one    lt dependency gt           lt groupId gt com google android lt  groupId gt           lt artifactId gt support-v7 lt  artifactId gt           lt scope gt system lt  scope gt           lt systemPath gt   android home  support v7 appcompat libs android-support-v7-appcompat jar lt  systemPath gt           lt version gt 19 0 1 lt  version gt   lt  dependency gt    Where  android home  is the root directory of the Android SDK and it uses systemPath instead of repository

Without Gradle  Click here for the Gradle solution    Create a support library project   Import your library project to Intellij from Eclipse project  this step only applies if you created your library in Eclipse   Right click on module and choose Open Module Settings  Setup libraries of v7 jar file  Setup library module of v7   Setup app module dependency of v7 library module
