Android part for LCL is far from complete, but already usable for some
small apps. I don't think it's production ready anyway. There are
native android controls package (not in lazarus package format) made
by a chinese Lazarus programmer (search the android subforum), but I
haven't really used it, just testing the example. It has no form
designer, so you have to code everything by hand. It's somewhat more
complete than LCL Custom Drawn for Android, though. The tightest
Android implementation is the FPC JVM, which has full access to all
Android libraries and the bindings can be updated with javapp app.
It's also pure code at the moment and has slightly different supported
syntax than regular Object Pascal, specially designed to interface
with Java.

I tried XE5 for a few days to see how the android stuff works there.
Basically it works, but I found it is not for me. It is not done
through VCL, but by Firemonkey. The finall app is too big for me
(about 10 MB with database).
In a past I created some apps in Eclipse, now in InteliJIdea. For me
it is the best tool for android. The main problem is, it is not
pascal   I see a big potential in FPC for JVM. Because native for
android is JAVA. But as Leledumbo said, You have to code just like  in
JAVA. Especially User interface. Maybe some special components wich
will wrap all necesary "java" code could be done. And then it could be
very usefull.
I have not tried LCL, But as other users said, it is not ready for too
compelx apps yet.

Well, You can try "Lazarus Android Module Wizard"

https://github.com/jmpessoa/lazandroidmodulewizard....

follows some images and code for simple curiosity ... and the
component palette page "Android Bridges"

*.lfm

Code: [Select]object AndroidModule1: TAndroidModule1
  OnCreate = DataModuleCreate
  OldCreateOrder = False
  BackButton = False
  Title = 'jForm'
  BackgroundColor = colbrBlack
  OnJNIPrompt = DataModuleJNIPrompt
  Height = 150
  HorizontalOffset = 330
  VerticalOffset = 145
  Width = 150
  object jButton1: jButton
    Id = 0
    PosRelativeToAnchor = []
    PosRelativeToParent = []
    LayoutParamWidth = lpMatchParent
    LayoutParamHeight = lpWrapContent
    MarginLeft = 5
    MarginTop = 5
    MarginRight = 5
    MarginBottom = 5
    Visible = True
    BackgroundColor = colbrDefault
    Text = 'jButton'
    FontColor = colbrDefault
    FontSize = 0
    OnClick = jButton1Click
    left = 55
    top = 52
  end
end

*.pas
Code: [Select]{Hint: save all files to location:
C:\adt32\eclipse\workspace\AppDemo4\jni }
unit unit1;
 
{$mode delphi}
 
interface
 
uses
  Classes, SysUtils, And_jni, And_jni_Bridge, Laz_And_Controls;
 
type

  { TAndroidModule1 }

  TAndroidModule1 = class(jForm)
      jButton1: jButton;
      procedure DataModuleCreate(Sender: TObject);
      procedure DataModuleJNIPrompt(Sender: TObject);
      procedure jButton1Click(Sender: TObject);
    private
      {private declarations}
    public
      {public declarations}
  end;
 
var
  AndroidModule1: TAndroidModule1;

implementation
 
{$R *.lfm}

{ TAndroidModule1 }

procedure TAndroidModule1.jButton1Click(Sender: TObject);
begin
  ShowMessage('Hello World!');
end;

procedure TAndroidModule1.DataModuleCreate(Sender: TObject);
begin           //fix to *.lfm fail on cross compile Laz4Android..
    Self.OnJNIPrompt:= DataModuleJNIPrompt;
end;

procedure TAndroidModule1.DataModuleJNIPrompt(Sender: TObject);
begin
   Self.show
end;

end.
