In the previous section, we learned how to use file for Android data storage. However, such data is stored in applications. Therefore, the size of such stored files must be limited, sometimes we need to store larger files, such as movies, which uses our sdsard memory card. Android also provides sdcard related operations. Environment class can implement this funct
