android.content.res.AssetManager Class Overview Provides access to an application's raw asset files; see Resources for the way most applications will want to retrieve their resource data. This class presents a lower-level API that allows you to open and read raw files that have been bundled with the application as a simple stream of bytes. asset폴더에 위치한 파일을 찾거나 관리한다. public class File extends Object implements Serializable Comparable<T> java.lang.Object    ↳ java.io.File Class Overview An "abstract" representation of a file system entity identified by a pathname. The pathname may be absolute (relative to the root directory of the file system) or relative to the current directory in which the program is running. The actual file referenced by a File may or may not exist. It may also, despite the name File, be a directory or other non-regular file. This class provides limited functionality for getting/setting file permissions, file type, and last modified time. On Android strings are converted to UTF-8 byte sequences when sending filenames to the operating system, and byte sequences returned by the operating system (from the various list methods) are converted to strings by decoding them as UTF-8 byte sequences.
