Hi All,

recently I started experimenting with Android and have created a small
demo application. It allows to write your own simple application - just
edit the prg source file and rebuild the apk, Some details and an
application package - at http://www.kresin.ru/en/h4a.html

Now I think over possibility to create Android GUI components from
Harbour code - something like Android GUI farmework for Harbour.

Regards, Alexander.

Version 2 is uploaded:

Added additional support for <i>hrb</i> updates. An update module is
included in <i>testhrb.prg</i>, it allows to get new <i>hrb</i> files
from my site.
Besides, a problem solved, related to some Android feature - it
doesn't close an application after closing a main window (Activity).

Regards, Alexander.

Francesco,

I guess you are referring to using QT on Android.

I don't want to start a debate about QT pros and cons. The fact is that I simply decided that QT will not be my way on Android.

So, my wish (as I've stated in other thread) is to be able to use plain Harbour for Androind (fast and lightweight) using HTML/CSS/JavaScript GUIs as (ie) RFO BASIC does, meaning, something like this:

html.open
html.load.url "file:///sdcard/rfo-basic/data/myform.html"
do
html.get.datalink data$
until data$ <> ""
data$ = mid$(data$,5)
print "Form data: "+data$


In addition, you could use strings instead of HTML files, so, we could create our HTML forms dinamycally from Harbour.

input "Name:", name$

frm$ = "<form action=\"form\">Name: <br>" + ~
"<input type=\"text\" name=\"name\" value=\"" + ~
name$ + "\"><br><br>" + ~
"<input type=\"submit\" name=\"submit\" value=\"submit\">" + ~
"</form>"
html.open
html.load.string frm$
do
html.get.datalink data$
until data$ <> ""
data$ = mid$(data$,5)
print "Form data: "+data$


The possibilities are huge.

Note that only three things are required to make this work: html.open, html.load and html.get.datalink.

Dreaming a little more... if these features could be added to all platforms supported by Harbour, we will have a universal, multi-platform, lightweight and simple alternative GUI for our programs: HTML.

More info on RFO BASIC HTML interface: http://rfobasic.com/#section-10.3

Roberto.

Thanks, Roberto.

> If we could catch webview events from Harbour (ie: form's submit button) we could build our GUIs with plain HTML.

I look at this direction, too.
But now I gradually, little by little, try to implement another approach - creating natural Android GUI compenents with Harbour code - some HDroidGUI.

Regards, Alexander.

Version 4 has been uploaded:

Mastering the technique of calling Java methods from Harbour and debugging techniques - added Harbour function h4a_isInternetOn() to determine whether there is an Internet connection and h4a_Wrlog( sText ) - write debug messages to a log for saving to a file using
adb shell logcat.

Scripts are slightly modified.

Regards, Alexander.

Ok good to have on github so we have a place to send issues and testing results


The github repository is created: http://github.com/alkresin/h4aFirstApp

But mostly I'm working on another project - real framework for creating Harbour applications for Android - something, which may be called HDroidGUI. For now it is based on a similar approach - using hrb files in assets and it is able already to create a simple interface with textviews, editviews, checkboxes and buttons, set/get values to/from these items and handle button clicks.

BTW FYI in my test of app (ver 4) , after choosing items the displayed result is too quick to read it show result and return to main menu...


Strange. It works normally here on two emulators and on my tablet.
