I know I'm reaching here... but does anyone know of a DBF viewer for
Android phones?

I have a system that I would like to check every so often. I can FTP
in and pull files but I can't find an app to view them on my phone.
These are simple databases; no relations and I don't need any index
support.

Dear Byteguy:

However, I'd recommend you write a server-side application, and let
the tablet / smart-phone poll it for the necessary information.
Otherwise, you are asking for data corruption, and heavy usage of what
is normally a very expensive (and flaky) data channel.

Note that The Oasis has source code for the production of HTML files
from databases, and that all these handheld devices know how to handle
HTML.

Thanks for the suggestions but neither of these are going to work for
my situation (which, I know, is more than a little unique).

The files are moving around using an FTP "drop box" idea. None of the
computers involved stay connected to the internet very long. Cellica
requires a computer-side server running to serv up the files. No
connection, no files.

Also, the point is to check the file that is actually being posted and
moved and not some representation of it so I don't want to convert the
data and read a converted version.

So you will need the equivalent of a program to watch for a connected
computer, and then get whatever it has that is new.

More choices here, including MySQL:

Bitorrent was what I was thinking, and could not remember.

Might be better still to have it emailed to the handheld... better
security, and better handshaking possible.

None of this is going to work.

MySQL can't read DBF without a $99 convert tool (which, doesn't look
like it can run on Android anyway so it can't work in the phone). All
the other options on the search are either proprietary format or bad
results (I don't care about "Geun-seok Jang's latest photos, old
photos, from childhood pictures!") ;)

Emailing to the handset isn't needed, I can go to the FTP drop-box
using AndFTP (wonderful program) and pull a file. I just can't READ
the file once I get my own copy.

Did you *ask* them? MySQL accepts DBFs in the real world, without any
adders.

I used it too.

So I guess you will have to write the wrapper yourself in Java, and
express it as an Android app. So here are some Java choices:
http://sourceforge.net/projects/xbasej/?_test=beta
http://sourceforge.net/projects/dans-dbf-lib/?_test=beta

https://market.android.com/details?id=com.kartdata.pcmdb&feature=search_result
... this says it does viewing, and the file format includes DBF.

Worth a look anyway. Not sure what it will do without the associated
SHP file.

Good luck to you.

They say "If you considering to migrate data across MySQL, Oracle, MS
SQL, MS Access, MS Excel or DBase you will need this program:http://
goo.gl/LYOTt"

Yep, way more than I want to get into for a "quick way to check some
files."

That's a plotting system and not a general data viewer. Also, you
have to love that their developer website sets off "redirecting to
pornography" warnings in my firewalls.

Oh well, I appreciate the attempt to help. I was hoping that someone
somewhere was USING an app; I've already done all the same searches
you've given me. It just looks like (as I expected) DBF browsers
didn't live long enough to see Android.

Sure, just not in a Clipper forum. Check on FiveWin. They have a
product where you can compile (x)Harbour apps (with caveats I am sure)
for use on Android devices. This could include something like DBU.

It is really clear your choice of solution, isn't. Android wants you
to move to SQL. Most of the database world wants to go to SQL, or
something better still. And that isn't DBF.

I encourage you to revisit your preferred solution, since the
"enablers" you require do not appear to exist.

Again, good luck.
