 ## Android Studio Tips
 
  * Configuration instructions can be found [here](http://tools.android.com/tech-docs/configuration). One suggestions:
     * Launch it with more RAM: `STUDIO_VM_OPTIONS=-Xmx2048m /opt/android-studio-stable/bin/studio-launcher.sh`
  * If you ever need to reset it: `rm -r ~/.AndroidStudio*/`
+ * Import Android style settings:
+    * Help -> Find Action -> Code Style -> Java -> Manage -> Import
+       * Select `third_party/android_platform/development/ide/intellij/codestyles/AndroidStyle.xml`
