Have you check the wiki? It should have all the information you need:
https://wiki.lazarus.freepascal.org/Portal:Android

There are several ways for Pascal-Android programming: LAMW, JVM,
Custom Drawn, SDL:
https://forum.lazarus.freepascal.org/index.php/topic,38777.msg264428.h
tml#msg264428

But the most feature-rich is Lazarus Android Module Wizard:
https://wiki.lazarus.freepascal.org/LAMW

LAMW currently does not have detailed documentation but the wiki page
in the link above is up-to-date. The hardest thing about Android
programming is preparing the cross compiler and setting up toolchain,
you should have no problem if you follow the tutorial correctly. You
may need a fast internet connection, the size of toolchain you need to
download is several GBs.

Once LAMW downloaded, you should read these before start using LAMW:
https://github.com/jmpessoa/lazandroidmodulewizard/tree/master/docs

Some things you need to know are all the components you use in
Windows/Linux cannot be used in Android (unless you use CustomDrawn
components). LAMW provides its own components. There is no
documentation about them but you can find examples how to use them
from the source code downloaded in the folder .../demos. And Android
screen layout system differs from Windows/Linux. You should search the
web or forum to better understand how Android screen layout works.

If you ask questions about LAMW, you may not get answer quickly, we
all are new in Android programming. Be patient, the developer
regularly checks this forum.

I also recently started learning LAMW. On the Russian-language forum,
I posted a detailed instruction with an example (Lazarus and Android
_LAMW-master_.pdf and WebView.rar). Perhaps it will be useful to you.
It is written in Russian, but with the help of Google Translate you
can translate into your native language.

Which is of course half the problem: there's no way for the wiki to
automatically mark that a certain technique is now the best supported
one and that others aren't getting much TLC, and most people
contributing to it have a natural reluctance to boost their own pet
project by deleting out-of-date text.
