title: Gradle build: resource android:style/TextAppearance.Material not found
body: <p>I just installed AndroidStudio and imported an old Eclipse ADT project (API level 18). However, when trying to build this project in AndroidStudio, I get the following errors:</p>

  <p>How can I fix this error? Which further information shall I provide?</p>
  
  <p>This is the import protocol, in case it helps:</p>
  
  <pre><code>ECLIPSE ANDROID PROJECT IMPORT SUMMARY
  ======================================
  
  Manifest Merging:
  -----------------
  Your project uses libraries that provide manifests, and your Eclipse
  project did not explicitly turn on manifest merging. In Android Gradle
  projects, manifests are always merged (meaning that contents from your
  libraries' manifests will be merged into the app manifest. If you had
  manually copied contents from library manifests into your app manifest
  you may need to remove these for the app to build correctly.
  
  Ignored Files:
  --------------
  The following files were *not* copied into the new Gradle project; you
  should evaluate whether these are still needed in your project and if
  so manually move them:
  
  * .gitignore
  * ic_launcher-web.png
  * proguard-project.txt
  
  Replaced Jars with Dependencies:
  --------------------------------
  The importer recognized the following .jar files as third party
  libraries and replaced them with Gradle dependencies instead. This has
  the advantage that more explicit version information is known, and the
  libraries can be updated automatically. However, it is possible that
  the .jar file in your project was of an older version than the
  dependency we picked, which could render the project not compileable.
  You can disable the jar replacement in the import wizard and try again:
  
  android-support-v4.jar =&gt; com.android.support:support-v4:18.0.0
  
  Replaced Libraries with Dependencies:
  -------------------------------------
  The importer recognized the following library projects as third party
  libraries and replaced them with Gradle dependencies instead. This has
  the advantage that more explicit version information is known, and the
  libraries can be updated automatically. However, it is possible that
  the source files in your project were of an older version than the
  dependency we picked, which could render the project not compileable.
  You can disable the library replacement in the import wizard and try
  again:
  
  google-play-services_lib =&gt; [com.google.android.gms:play-services:+]
  
  Moved Files:
  ------------
  Android Gradle projects use a different directory structure than ADT
  Eclipse projects. Here's how the projects were restructured:
  
  * AndroidManifest.xml =&gt; app\src\main\AndroidManifest.xml
  * assets\ =&gt; app\src\main\assets
  * libs\commons-net-3.3.jar =&gt; app\libs\commons-net-3.3.jar
  * res\ =&gt; app\src\main\res\
  * src\ =&gt; app\src\main\java\
  
  Next Steps:
  -----------
  You can now build the project. The Gradle project needs network
  connectivity to download dependencies.
  
  Bugs:
  -----
  If for some reason your project does not build, and you determine that
  it is due to a bug or limitation of the Eclipse to Gradle importer,
  please file a bug at http://b.android.com with category
  Component-Tools.
