AFAIK fpGUI only has GDI and X11 backend, it won't run on Android
unless you have X11 installed.

Is it possible to implement some kind of android backend borrowing
lazarus/CustomDrawn code?

Possibility is always there, but I don't think borrowing from LCL can
be done that simple because fpGUI and LCL has different structure.
Basically, you need to add another corelib backend and implement what
existing backends do.

Ok!
 I will take a look on the code ...
My idea is that fpgui is maybe a better choice for mobile dev. this
will break aprat from the hole bloat inherited from the delphi
paradigm

I choose LazAndroidModuleWizard instead. It has native look and feel
and the resulting binary is not too bloated.

Hum, i was thinking that Android uses X11 (if not what does it use ?)

Thanks

And what about OpenGL backend ... this will be even better and less
work to port to iOS

Found a quite good one (too much if I write one myself):
http://blog.imgtec.com/news/learning-about-the-android-graphics-
subsystem
If you're too lazy to read, the conclusion: it has its own graphics
stack, independent of existing solutions including X11

Same, whatever backend you choose, if it doesn't exist yet, somebody
has to create it.

Ok Good i will write it
fpgui has his own event loop and does the drawing it self, customdrawn
uses lazarus event loop and is using some sort of canvas to draw on it
and does not depend on the system windowing system
so i supose that i have to "extract" the adnroid interface code from
CD and integrate it in fpgui


let's start

And you have your first fan => me. 

I am extremely interested...

Perfect
I will create a git repo tomorrow ...
what is your knowledge of fpc (1 to 10) ?

Blestan,

I had the same idea.
So, how did it go?

Sounds interesting...

And just in case it won't work you can try KOTLIN, they say it's
better than JAVA... the new JAVA 2.0 
[Android Studio + KOTLIN]
