Manjaro / Arch Linux: As of 2023-May-22 installing on Manjaro works,
and can be used for building a project but there is an issue
with a workaround:
 * Lazarus Menu "Run" | "[LAMW] Build Android Apk and Run" fails
   - Instead use "Run" | "Build" and if the build is successful open a terminal
     in the project folder and run ./gradle-local-build.sh to build the APKs

Needed simple instructions to get an up-to-date Android build environment setup on Linux.
Thanks to other developers for sharing their hard work, utilities, and helpful information.

for 32-bit:  ARMv7a + VFPv3 for Architecture/Instructions
for 64-bit:  Aarch64 for Architecture/Instructions
Min. Device API: 19  (Google recommended minimum SDK version)

Bug work-around: After creating a new project, save all, close lazarus, and re-open lazarus (it reloads the last open project)
(this allows placement of controls on form without throwing an error - SEE HERE)

(Project | Open Project) Open the controls.lpi file in the demo project jni folder
Bug work-around 1: File | Save All. Close lazarus, and re-run lazarus (by default it opens the last project).
for 32-bit:  Change LAMW project options | Min SDK: 19 and Build tab | Chipset: ARMv7a+VFPv3
for 64-bit:  Change LAMW project options | Min SDK: 19 and Build tab | Chipset: Aarch64
Bug work-around 2: Delete the custom options at Project | Project Options | Custom Options.
File | Save All
Perform a Run | Clean up and Build
Open a terminal in the project folder and run: ./gradle-local-build.sh
(or Perform a Run | Build Clean up and Build)
If successful, the apk files will be in

2023-Nov-21 ver 2.1
 Add p7zip to package installation (fpcupdeluxe wants to use it)
 Update FPCUPdeluxe version to 2.4.0a
 Also tested Android SDK api level 33
 Only tested on xubuntu-23.04-minimal-amd64 with aarch64 build

2023-May-22 ver 2.0
  Added LAMW bug work-arounds for two cases:
    1) Directly after creating a new project, save the project, close Lazarus, and re-open.
    2) Directly after opening a demo project, save the project, close Lazarus, and re-open.
    
  Tested on more distro versions
    xubuntu-20.04.6-desktop-amd64
    xubuntu-22.04.2-desktop-amd64 (minimal install)
    xubuntu-23.04-minimal-amd64 (NOTE: I will not usually test on non-LTS versions)
    manjaro-xfce-22.1.2-minimal-230518-linux61 (based on arch linux)
    
  Manjaro does not have special issues with changing the LAMW project chipset - remove previous comment
  Don't explicitly install freeglut3 (it gets pulled in if needed by freeglut3-dev)
  Remove subversion from install packages (fpc and lazarus both use git now)
  Remove apache-ant from pacman (arch linux) install (fpcupdeluxe installs a private copy)
  Testing with updated software components:
    fpcupdeluxe 2.2.0r
    OpenJDK ver 11.0.19
    Lazarus stable v2.2.6

2023-Feb-06 ver 1.9

 Android Command-Line Tools for Linux build 9477386
 OpenJDK 11.0.17
 Gradle 6.8.3 (installed automatically by FPCUPdeluxe)
