android studio 添加assets文件夹

方法1

方法2

Looking inside the .iml file of your project you will see the following line:

 

 

 <option name="ASSETS_FOLDER_RELATIVE_PATH" value="/src/main/assets"></option>

 

 

 

 

Therefore the "assets" folder is already declared for Gradle but you need to create it under src/main/ (I'm using AS 0.4.2)
