Manjaro Linux (based on Arch Linux).
(Note: not tested since 2018-Apr-19)
Manjaro requires these changes:

1) Instead of apt-get, use pacman with these packages:
# Install libraries and tools
sudo pacman -S --needed libx11 gtk2 gdk-pixbuf2 cairo pango libxtst atk freeglut
sudo pacman -S --needed git subversion make gdb zip unzip unrar wget
sudo pacman -S --needed android-tools apache-ant jdk8-openjdk

2) #Install SDK packages and NDK using sdkmanager
In my test the NDK was not installing and sdkmanager gave an error "No space left on device".  By default /tmp is a tmpfs limited to half the size of your RAM, if your RAM size is small, you may have to temporarily unmount /tmp from tmpfs before installing sdk/ndk packages:
sudo umount -l /tmp
(remember to manually delete files in /tmp before rebooting)

3) The PATH environment is setup in a different file:
# Use a text editor to open $HOME/.bash_profile and add this text below:
# example: kate $HOME/.bash_profile
export PATH="${PATH}:${HOME}/android/ndk-toolchain"
export PATH="${PATH}:${HOME}/android/gradle-4.10.3/bin"
export ANDROID_SDK_ROOT="$HOME/android/sdk"

4) When setting LAMW paths, the JDK has a different path on Manjaro
# Select Tools menu > [Lamw] Android Module Wizard > Paths Settings: [Jdk, Sdk, Ndk, ...]:
...
# Path to Java JDK: /usr/lib/jvm/java-8-openjdk

Comments for 2019-May-20 ver 1.3

> 24. #Install SDK packages and NDK
When installing the NDK using sdkmanager, you cannot select an older version, it installs the latest version.

> 26.  ./sdkmanager "platforms;android-26" "build-tools;26.0.3" "tools" "ndk-bundle" "extras;android;m2repository"
I chose to install Android platform 26.  A given Android platform also supports previous API Levels.  (usage stats for Andriod API Levels).  As of gradle plugin 3.0.0, the appropriate build-tools package is automatically downloaded if needed during the gradle build, but I included it here to work around a LAMW issue.  To view a list of available packages use ./sdkmanager --list

> 35. # download and extract Gradle 4.10.3
note to self:  LAMW uses the Gradle directory name internally to determine the Gradle version

> 42. # Use a text editor to open $HOME/.profile and add this text below:
.profile seems to be the proper file for this on Ubuntu(s).  .bashrc gets re-run for every subshell which creates multiple path entries.
(NOTE:  .profile is not called if ~/.bash_profile or ~./bash_login exist)

> 51. # Download FPCUPdeluxe
If the latest version of FPCUPdeluxe doesn't build FPC/Lazarus successfully (particularly if you're using stable/stable), try the same version that I tested.

> 59. # 1) On "Basic" tab, select FPC version "fixes3.2" & Lazarus version "fixes2.0"
Originally I used trunk for both FPC and Lazarus in order to work with the most current code.  Depending the state of Lazarus/FPC in regards to bugs and ARM/Android issues, you may have to use different versions.  As of 2019-May-20, FPC trunk is causing a "buffer error" when starting Lazarus.  I switched to the latest "fixes" versions of both FPC and Lazarus which are newer than "stable", but more stable than "trunk".  There are some android related bugs fixed in FPC development version 3.1.1 and later (see here).

> 62. # 4) On Modules tab, select LAMW, Install module
Installing LAMW from FPCUPdeluxe pulls from GIT.  Do this anytime you want to update LAMW to the latest code.

2019-May-20
Building a simple test project:

Project | New Project...
LAMW [GUI] Android Module
Set project folder, (ex. /home/user/test)
Automated Build = Gradle
For 32-bit:  Architecture/Instructions = ARMv7a + VFPv3
For 64-bit:  Architecture/Instructions = Aarch64
Use defaults for other settings
Click OK
Click Save if prompted to save files
Drop a label, edit box, button on the form from Android Bridge Component Tab (jTextView, jEditText, jButton)
Run | Build
From a command line run "gradle_local_build.sh" from the project folder
if successful, your compiled APK files are in ./build/outputs/apk

Installing and Using the Android Emulator:
(the method described here uses the command line, another method is to install Android Studio)

#Install the emulator and a system image
cd ~/android/sdk/tools/bin
./sdkmanager "emulator" "system-images;android-24;default;armeabi-v7a"
(to get a list of system images use ./sdkmanager --list)

#Create some android virtual devices (AVD)
#generic test device
./avdmanager create avd -n "my_test_device" -k "system-images;android-24;default;armeabi-v7a"
#Galaxy Nexus device
./avdmanager create avd -n "Galaxy_Nexus" -d "Galaxy Nexus" -k "system-images;android-24;default;armeabi-v7a"
(to get a list of devices use ./avdmanager list devices)
(after creation, AVD files are stored in:  ~/.android/avd/)

#Run the emulator
cd ~/android/sdk/emulator
./emulator -no-snapshot-load -avd "my_test_device" -use-system-libs -gpu swiftshader_indirect
(to get a list of available AVDs, use ./emulator -list-avds)
(note: I had to use -gpu swiftshader_indirect to enable software rendering since I am running inside a virtual machine, more info here.  Inside my VM the emulator was running slow, so if you get any android "Process isn't responding" messages, click "Wait".  The emulator was unstable when loading from a snapshot, the workaround is to use -no-snapshot-load)

#Run your project in the emulator:
From a command line run "gradle_local_run.sh",
or from the Lazarus IDE menu select Run | [LAMW] Build Android Apk and Run

How to build demos
(still working on it. but have had some success by doing steps below as a 32-bit example):

Open a demo project and change
In Project | Project Options | Compiler Options | Paths

Libraries:
/home/[user]/android/sdk/ndk-bundle/platforms/android-27/arch-arm/usr/lib/;/home/[user]/android/sdk/ndk-bundle/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/lib/gcc/arm-linux-androideabi/4.9.x/
(remove [user] and replace with your user name)

Target File name:
../libs/armeabi-v7a/libcontrols

In Project | Project Options | Compiler Options | Custom Options
-Xd -CfVFPv3 -CpARMV7A -XParm-linux-androideabi- -FD/home/[user]/android/sdk/ndk-bundle/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin
(remove [user] and replace with your user name)
 
Run gradle_local_build.sh from a command line.

Hello, WayneSherman!

First: Thank you!  [I added your tutorial to git LAMW!]

About  "How to build demos"

We need some test,  Can you help?  [Please,  update your LAMW...  there is some bug fixed!]

1)  Open a demo and save it ...  what config changes you got [Libraries and Custom...]?

2)  Open a demo and and try "Run--> build" what config changes you got [Libraries and Custom...]?

The code is here: LAMW  "android_wizard\smartsesigner.pas"

  if IsDemoProject() then
  begin
    TryChangeDemoProjecPaths();
  end

Something I am doing wrong!

Since I am on Arch Linux I had to find out where to get the right packages...
But now - after running FPCUPdeluxe - i got several times the message:

Fpcupdeluxe has [created] a shortcut link in your home-directory to start Lazarus.
Shortcut-link: Lazarus_fpcupdeluxe
Lazarus MUST be started with this link !!
Fpcupdeluxe has also (tried to) create a desktop shortcut with the same name.

I do not have the "Android Module Wizard" in the tools menu. What can I check to get it done?

Thanks in advanced!

[FPCUPdeluxe] In module list:  Select LAMW, Install module

[WayneSherman]

> 50. # 3)
>[FPCUPdeluxe] In module list:  Select LAMW, Install module

Two other things to check:
1) Check if FPCUpdeluxe downloaded the LAMW files.  On my computer the LAMW files are found in ~/fpcupdeluxe/ccr/lamw
2) Read the FPCUpdeluxe log messages to see if there are any errors recompiling Lazarus

[HobbyDev]

Yes the LAMW ist installed. Checking the directory /home/user/fpcupdeluxe/ccr/lamw I found 11948 objects  with a total size of 61,5 MB.
But where to find the FPCUpDeluxe Log- files? If I am running the script I get the following messages in the terminal:

@HobbyDev
Could you give more details about the errors you encounter ? Your last post does not give much info.
* Does Lazarus start ?
* Do you have LAMW in the tools of Lazarus ?

(I am the maintainer of fpcupdeluxe)

[HobbyDev]

I just edited (extented) my last post. Please check this 
Yes - Lazarus is starting, and no I don't see anything regarding LAMW in Lazarus

[DonAlfredo]

Yes, this helps !

It seems that fpcupdeluxe was not able to find the LAMW files (reason yet unknown to me), so the most easy thing is to install LAMW manually.

Start Lazarus.
Click "Package" and Click "Open Package File (.lpk)"
Navigate towards (in ccr): android_bridges/tfpandroidbridge_pack.lpk
Click "Use"and click "Ïnstall"
Do the above also for:
android_wizard/lazandroidwizardpack.lpk
ide_tools/amw_ide_tools.lpk

This should give you LAMW tools in Lazarus.

Good luck !

[WayneSherman]

I just edited (extented) my last post. Please check this 
Yes - Lazarus is starting, and no I don't see anything regarding LAMW in Lazarus

In FPCUPdeluxe, I re-tested the FPC/Lazarus install, and at the moment Lazarus trunk does not compile (also stable/stable causes a compiler runtime error when compiling Lazarus).  I did get FPC trunk and Lazarus stable to work.  (tested with FPCUPdeluxe v1.6.0p)

Another possible clue regarding your installation of the LAMW module, my package paths are different from yours:
(excerpt from FPCUPdeluxe log)
  Name=lamw
  Description="A wizard to create JNI Android loadable module (.so) in Lazarus/Free Pascal using [datamodule like] Form Designer and Components!"
  Installdir=$(basedir)/ccr/$(name)
  Enabled=0
  GitURL=https://github.com/jmpessoa/lazandroidmodulewizard
  ArchiveURL=https://github.com/jmpessoa/lazandroidmodulewizard/archive/master.zip
  AddPackage1=$(Installdir)/android_bridges/tfpandroidbridge_pack.lpk
  AddPackage2=$(Installdir)/android_wizard/lazandroidwizardpack.lpk
  AddPackage3=$(Installdir)/ide_tools/amw_ide_tools.lpk
  UnInstall=rm -Rf $(Installdir)

Your paths have an additional directory:
AddPackage1=$(Installdir)/lamw-master/android_bridges/tfpandroidbridge_pack.lpk
AddPackage2=$(Installdir)/lamw-master/android_wizard/lazandroidwizardpack.lpk
AddPackage3=$(Installdir)/lamw-master/ide_tools/amw_ide_tools.lpk

[DonAlfredo]

@WayneSherman

I presume that HobbyDev does not have GIT installed. If not GIT available, fpcupdeluxe will download the LAMW-sources as a zip. This will add the extra path, but this should also be handled automagically by fpcupdeluxe, but not in the case of HobbyDev. And that is a strange error !
