Hi,
As the doc says - 'This method is not generally useful'
public boolean createNewFile ()
Since: API Level 1
Creates a new, empty file on the file system according to the path
information stored in this file. This method returns true if it
creates a file, false if the file already existed. Note that it
returns false even if the file is not a file (because it's a
directory, say).
This method is not generally useful. For creating temporary files, use
createTempFile(String, String) instead. For reading/writing files, use
FileInputStream, FileOutputStream, or RandomAccessFile, all of which
can create files.
Note that this method does not throw IOException if the file already
exists, even if it's not a regular file. Callers should always check
the return value, and may additionally want to call isFile().
Returns
true if the file has been created, false if it already exists.
Throws
IOException if it's not possible to create the file.
Regards
