FileUtils文件

public class FileUtils
 {

    public static String
 getPath(Context context, Uri uri) {

        if ("content".equalsIgnoreCase(uri.getScheme()))
 {

            String[]
 projection = { "_data" };

            Cursor
 cursor = null;

            try {

                cursor
 = context.getContentResolver().query(uri, projection,null,
null,
null);

                int column_index
 = cursor.getColumnIndexOrThrow("_data");

                if (cursor.moveToFirst())
 {

                    return cursor.getString(column_index);

                }

            }
catch (Exception
 e) {

                //
 Eat it

            }

        }

        else if ("file".equalsIgnoreCase(uri.getScheme()))
