You can use getFileStreamPath() instead of getDataDir(), if you just
want a place to put directories. In a future SDK there will be a new
set of APIs explicitly for creating directories.

Could you help me to check what's wrong with me?
Thank you.

It turns out that getFileStreamPath() will not accept path separators
in its argument.
But:
1- the above approach works to create a single-depth subdirectory
(i.e., no slashes).
2- if you want to create deeper subdirectory trees, you can do this:
File subdirectory = null;
try {
File basedirectory = getFileStreamPath( "basedir" );
subdirectory = new File( basedirectory, "subdir_0/
subdir_1" );
if ( ! subdirectory.exists() ) {
Log.i( LOGTAG, "attempt to create subdirectory: " +
subdirectory );
subdirectory.mkdirs(); // makes all subdir levels you need
}
}
catch ( FileNotFoundException e1 ) {
Log.e( LOGTAG, "oops 0", e1 );
}
This will create a subdirectory named (in the current SDK)
/data/data/<package>/files/basedir/subdir_0/subdir_1
If you provide an empty string to the first getFileStreamPath() call,
you will get
/data/data/<package>/files/subdir_0/subdir_1
but I'm not sure I'd want to rely on that behavior.

Thank you, I already updated my source code. In my example, I unpack a
zip file from the apk resource folder to the local application folder
so I can display the html pages with WebKit/WebView.
I too used an empty string to get the files folder.
