Dear ALL,
Although I have already marked this question as SOLVED, here am I again to present the results of my efforts of the last few days in developing a multi-field Android app using LAWM.
It is not a study in beauty, but it has the intended functionality and demonstrates a few interesting features. I am not entirely satisfied with the disposition of the components on the form, especially the lack of spaces between the rows of components. Anyway, this is just an experiment for the development of a similar, but more 'serious' and sophisticated scientific app with more or less the same look-and-feel.
The full source code is attached. I will appreciate any cosmetic and/or functional improvements.
With warmest regards,
