Blueprint for the J2ME client

Documentation on the implementation is here: http://wiki.sahana.lk/doku.php/dev:j2meclient

J2ME is the most widespread environment for mobile devices:

There should be a simple set of forms for data entry.

GPS coordinates should be taken automatically if available (inc via Bluetooth) or can be entered manually, where not available automatically.

The back-end transport is best done via SMS as this is cheap & widely-available.

  • compressed multi-part SMS to get maximal throughput.

The forms should be updatable via SMS.

This would work like the one which comes with FrontlineSMS, but be Open, as well as Free:

Sahana has a J2ME client for the PHP back-end, but this uses XML-RPC (=> requires Internet) & isn't maintained:

KUIX can be used to develop lightweight applications which work across may handhelds & forms can be customised easily via XML/CSS:

An alternative is J2MEPolish:

JavaRosa is a fast-developing framework which uses XForms

This supports using Mesh4j to do synchronisation via SMS:
