----------------------------------------------------------------------
jjur · 2015-01-04 15:52

Hi,
last days I'm trying to build and configure android export in
lazarus. 
I tried this tutorials in wiki:
1. http://wiki.freepascal.org/Custom_Drawn_Interface/Android   // i
created apk, but it crashed after run in my mobile, also tried to
change api from 8 to 18 
2. http://wiki.freepascal.org/Android_Programming
3. http://wiki.lazarus.freepascal.org/Android    // Completed, what
next?

I need to install it on linux (Ubuntu 14.10)
Testing on mobile Doogee DG550 (Android 4.4.2)

I need new and working tutorial.
Please, where i can find good, working tutorial? Or can you tell me,
what i have to do?
Thanks

It can't find the proper binutils.

 Either because
They are not  installedthey are installed but the path is not added to
the search path (simon says step2-3) they are installed but
differently named (not starting with arm-linux-androideabi- but a
slightly different naming

Thanks, it was number 3. In path i used was only shortcut as to
orginal file with expected name.

FPC default installation layout on *nix is different than windows. In
*nix, it's:
<install prefix dir>
- bin
- lib/fpc/<fpcversion>

Thanks, i think fpc is ready. But when i try build example project, at
start it show message http://oi57.tinypic.com/9sxh1k.jpg ( Package
fpcunitide is installed but not found .lpk file. Fictional package was
created.)
and when i try to build it, it end with error
http://oi58.tinypic.com/iyzcs1.jpg (main.pas(0,0) Fatal: Can not find
unit system used by main.) Where is problem now?

Just uninstall if you don't need the package, or reinstall if you do
(the package is shipped with lazarus, probably the IDE just misses the
path link).

Biggest guess: fpc.cfg doesn't contain -Fu pointing to correct units
directory (perhaps it's hardcoded to your stable fpc version)

Right click and select copy all and hidden messages (or something like
that) to reveal the actual error message.

Thanks, now it works, apk works.

And what i have to do if i want create a new project for android?
Can i use with small modifications this http://wiki.freepascal.org/Cus
tom_Drawn_Interface/Android#How_to_create_an_LCL_Android_Application ?

There are at least three ways if you use the arm-android compiler (and
another one using jvm-android compiler):
LCL Custom DrawnLazAndroidModuleWizardNative ActivityPick anyone you
like. Personally I prefer 2 due to its native look and feel with half-
RAD style, despite incompatible code with LCL.

----------------------------------------------------------------------
jjur · 2015-01-06 12:05

Which one is most similar to classic lazarus programming for pc?

I would like to try LCL Custom Drawn

I would like to try LCL Custom Drawn
Custom Drawn, but it doesn't have many controls implemented yet.
Usable enough for many common applications. Size overhead is the same
as desktop LCL app.

When i try build Androidlcl project from lazarus examples directory,
it retry show error with system.ppu. But file is really in
/usr/lib64/fpc/2.6.4/units/arm-android/rtl/system.ppu and example
project  from http://blog.naver.com/simonsayz/120198362100 don't shows
this error.
Code: [Select]androidlcltest.lpr(0,0) Fatal: Can not find system used
by androidlcltest, ppu=/usr/lib64/fpc/2.6.4/units/arm-

 Where can be problem now?

And how create project with LazAndroidModuleWizard?

the unit is part of lcl (see attached screenshot), open your lcl.lpk
and check whether lcl's lib directory produce .ppu and .o for the
unit.
