Where should the 'assets' directory be when using Android Studio?

Android FAQ: Where should the ’assets’ directory be when using Android Studio?

Solution: If you want to include an assets folder in your project when using Android Studio, create the folder as src/main/assets, i.e., as an assets folder under src/main.

You can later open files in the assets folder using code like this:

InputStream is = getBaseContext().getAssets().open(relativeFilename);

where relativeFilename is the name of your file, like foo.jpg.
