LAMW 0.8 on Ubuntu 18.04 Installation Guide

[Handoko]

The installation guide I wrote previously does not work anymore due to some issues with the latest versions of Android NDK and SDK.

Lazarus 1.8.0RC5 + LAMW
http://forum.lazarus.freepascal.org/index.php/topic,38777.0.html

So I write this new installation guide, which has been tested to work on:
- Ubuntu Mate 18.04 64-bit
- Lazarus 1.8.4 64-bit GTK2 FPC 3.0.4
- Lazarus Android Module Wizard 0.8 revision 754
- Android 7 mobile phone

This installation uses the combination of these software:
- Android NDK Revision 11c
- Android SDK Tools 25.2.5 (SDK API25)
- OpenJDK 8
- Subversion, Android adb, Ant

If you want to see the screenshots during this installation process, you can visit here:

=== Before Start Installing ===

You need to have Lazarus and FPC installed that have the ability to do cross compiling. The Lazarus/FPC installed from Ubuntu default repository may fail to cross compile because of missing make files issue.

If you have LAMW installed previously, you have to uninstall all the related packages and remove the ~/Android folder in your computer.

In this installation guide, the texts in green color mean you need to type them in your Linux Terminal.

=== Download and Install Android NDK, SDK and Required Packages ===

Warning:
The total size of the items you're going to download in this "Download and Install Android NDK, SDK and Required Packages" section is about 2.2 GB, so you better use a fast internet connection.

#IFDEF ANDROID
#IFDEF CPUARM
-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget
-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget/*
-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget/rtl
#ENDIF
#ENDIF

=== Lazarus Android Module Wizard Installation ===

For the steps #33, #35, #37 below, the *.lpk files are inside ~/Android/lazandroidmodulewizard.git/trunk

You need to change the text [handoko] with the current username on your computer.

29. cd ~/Android

30. svn co https://github.com/jmpessoa/lazandroidmodulewizard.git

31. ln -sf ~/Android/lazandroidmodulewizard.git ~/Android/lazandroidmodulewizard

Thank you very much for the instructions. 
I have never programmed for mobile phones, but I wonder if with LAMW you can do a normal program, with all the Object Pascal language, I also wonder if you can even call functions that are in a dll/so made in C.

[jmpessoa]

I also wonder if you can even call functions that are in a dll/so made in C.

Yes!  You have two possiblity:

1) Including a ".so" compiled for arm-android and the ".pas" header...
2)  You can try import the ".c" and. ".h" directly....  LAMW will
try build the ".so" and convert your ".h" to ".pas"


PS. Thanks to Handoko by the new Linux Tutorial!
