-ECLIPSE ANDROID PROJECT IMPORT SUMMARY
-======================================
-
-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
-* NOTICE
-* README.md
-
-Moved Files:
-------------
-Android Gradle projects use a different directory structure than ADT
-Eclipse projects. Here's how the projects were restructured:
-
-* AndroidManifest.xml => app\src\main\AndroidManifest.xml
-* res\ => app\src\main\res\
-* src\ => 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.
-
-(This import summary is for your information only, and can be deleted
-after import once you are satisfied with the results.)
