Hi everybody,

I just came across LAMW and the possibility to develop for Android
with Lazarus, which is simply amazing! So first of all, allow me to
send a biiiiig thank you to the developers, keep up this great work!

I just started to learn and to know the environment, so I might ask
something trivial: is there a way to draw, in jdrawingview for
instance, some filled shapes like rectangles, circles etc.?

Thank you very much.

TShape perhaps?
You can simply drop it on afrom and set it's properties.

What about "Demos"?

AppDrawingViewDemo1
AppDrawingViewDemo2
AppDrawingInBitmap
AppDrawingInBitmapAndDensity
ColorPicker
AppSurfaceViewDemo1
AppGridColorPickerDemo1

I don't remember about "filled shapes" ...

I'm having problems compiling demos, I always get a "system unit not
found" error.
Am I missing something? (obviously yes...   )
Thank you.

beginner I am doing same  to learn demos .

Hi. tango13!

How you get your "Lazarus for Android"?

With LAMW Manager (on Windows 10) which, by the way, is just great!
Thank you.

@tango13

Can you create a new LAMW project and put the "*.lpi" file here?

Thanks for your suggestion, it worked and now at least I can compile
the code.
However, I still get an error while building the apk, the error is
"Error: \path\to\file\Controls.java:2675: error: package R does not
exist".
Can I try anything else?
Thanks a lot!

@Tango13

Can you do some test?

Please, change the "Controls.java" line 2675:
[LAMW folder "......\android_wizard\smartdesigner\java"]

old:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i   Class<?>
res = R.drawable.class; 
to

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i  Class<?>
res = android.R.drawable.class;

Ok, it seems that we are moving forward 
On the lines  Class<?> res = R.drawable.class; your suggestion made
the error disappear.
However, there are more lines with the same error, lines like Code:
Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i  dw =
drawableToBitmap (this.controls.activity.getResources().getDrawable(R.
drawable.ic_launcher));If I make the same modification I get a "cannot
find symbol" error.

Oh, and I forgot to mention that I get errors also in jCommons.java,
in lines like
return  R.color.accent;
The error is the same "package R does not exist".
Thank you.

Well, if you got error here:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i dw =
drawableToBitmap (this.controls.activity.getResources().getDrawable(R.
drawable.ic_launcher)); 
then your project is  messy!

So, please,  create a NEW project!!!!
