Hi,

Platform: Windows 7/64

Have tried with

Lazarus: 0.9.30.4, FPC: 2.6.0
Lazarus-1.1-39266-fpc-2.6.0-20121109-win32, FPC: 2.6.0
Lazarus-1.1-39274-fpc-2.6.1-20121113-win32, FPC: 2.6.0
Lazarus-1.1-39275-fpc-2.6.1-20121113-win64, FPC: 2.6.0

and succeed to generate, install and run androidlcl-example on
android-phone
but when I add a new button and try to add OnClick-event I always get
error:

Unable to create new method.
In message window the error is: unit not found: types
and Controls unit opens and cursor set to types in uses clause.

Have done Rescan Ftp Source Directory but no luck.
Unit Controls always show up and I wonder if the problem can be due to
the fact
that there is unit controls in lcl\units\arm-linux and also in 
lcl\units\i386-win32
lcl\units\x86_64-win64.

In which order is the code loaded?

Regards
stab

the same is happening with me, but when I put a new button I work as
nonandroid application

Hi zeljkoc,

Thanks for replying.

Do you mean that you have succeeded by adding OnClick-event in
nonandroid app, saving and then compiling android app as both uses
same code.

Hi all,

The trick seem to be to add new functionality(only tested so far vid
buttonOnClick) in NonAndroidApp, save, open AndroidApp using same
code, build, generate key, build_apk, install

Hello,

I had the same problem when I used the pre-compiled compiler for
Windows as described in:
http://wiki.lazarus.freepascal.org/Custom_Drawn_Interface/Android#Usin
g_the_pre-compiled_compiler_in_Windows


The error message stated that the unit Classes (its source) cannot be
found.

This is how I solved it:

1. I downloaded the source from the svn:
https://p-tools.svn.sourceforge.net/svnroot/p-tools/fpc4android
I used TortoiseSVN: at first its "Checkout" function and then using
its "Export" function (to get only the sources without the .svn stuff
around) I copied the sources to a folder in my computer.

2. Under the fpc\2.5.1 folder (which has been created in the process
described on the wiki page linked above) I created a folder called
"source" (C:\lazarus11\fpc\2.5.1\source in my case) and copied there
the folders "rtl" and "packages" from the downloaded sources.

3. Then I used "Tools/Rescan Ftp Source Directory" from the main menu
of Lazarus

And now it works correctly
