+
+Moved Files:
+------------
+Android Gradle projects use a different directory structure than ADT
+Eclipse projects. Here's how the projects were restructured:
+
+* AndroidManifest.xml => libstreaming/src/main/AndroidManifest.xml
+* res/ => libstreaming/src/main/res/
+* src/ => libstreaming/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.
