MediaPlayer doc for setDataSource by file pathname

     *

     * @param path the path of the file, or the http/rtsp URL of the stream you want to play

     * @throws IllegalStateException if it is called in an invalid state

     *

     * <p>When <code>path</code> refers to a local file, the file may actually be opened by a

     * process other than the calling application.  This implies that the pathname

     * should be an absolute path (as any other process runs with unspecified current working

     * directory), and that the pathname should reference a world-readable file.

     * As an alternative, the application could first open the file for reading,

     * and then use the file descriptor form {@link #setDataSource(FileDescriptor)}.
