Title: [HowTo] Android Development Environment on Linux (FPCUPdeluxe + LAMW)
Post by: WayneSherman on April 02, 2018, 10:36:57 pm
Updated 2021-Oct-21 ver 1.6
(for changes see here (https://forum.lazarus.freepascal.org/index.php/topic,40750.msg422453.html#msg422453))

See also:  http://wiki.freepascal.org/LAMW_on_Linux (http://wiki.freepascal.org/LAMW_on_Linux)

Motivation:
  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.
Please provide feedback if you find any issues, or if there are ways to simplify even more.

Everything is self-contained under the user's home "android" folder
$HOME/android/sdk  (android sdk and build tools)
$HOME/android/sdk/ndk-bundle  (android ndk)
$HOME/android/fpcupdeluxe_app  (FPCUPdeluxe installer)
$HOME/android/projects  (default LAMW projects folder)
$HOME/android/fpc-lazarus  (FPC, Lazarus built w/ LAMW)
$HOME/android/fpc-lazarus/ccr/lamw  (LAMW files and demos)
$HOME/android/fpc-lazarus/ccr/lamw-gradle  (gradle build tool)

Versions Tested
Xubuntu 20.04 64-bit w/ latest updates installed

Android Command-Line Tools for Linux build 7583922
OpenJDK 11
Android SDK/API Level 29 (Android 10)
Android NDK revision 22
Gradle 6.8.3 (installed automatically by FPCUPdeluxe)

FPCUPdeluxe ver 2.2.0c
FPC stable v3.2.2
Lazarus stable v2.0.12

32-bit CPU Target: ARMv7a + VFPv3 (hardware floating point)
64-bit CPU Target: Aarch64

I recommend running these commands one at a time so you can verify the results before moving on to the next step.

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 (https://developer.android.com/about/dashboards/index.html)).  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 (http://wiki.freepascal.org/Android#Known_issues)).

> 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 (https://developer.android.com/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 (https://developer.android.com/studio/run/emulator-acceleration.html).  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"
Quote
  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:
Quote
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!

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

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:

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 ?

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 !

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

  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

@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 !

(see first post (https://forum.lazarus.freepascal.org/index.php/topic,40750.msg281604.html#msg281604))
1) Add gdb and wget to package install
2) More simplification, only creating one symlink instead of four (also required adjustment to the LAMW NDK path)
3) Regarding which versions of FPC and Lazarus to install using FPCUPdeluxe, see "> 45" comments in post #2 (https://forum.lazarus.freepascal.org/index.php/topic,40750.msg281605.html#msg281605).

Well done! Pretty good job you have done! :D

Im almost through! The last point I have is, when creating the test project I get the failure message that I  have to install sdk 26.x.y. But if I try
Code: [Select]
$ ./sdkmanager "26.0.2"I get
Code: [Select]
Warning: Failed to find package 26.0.2I checked the directory
Code: [Select]
/home/user/Android/android-sdk/platforms/android-26/ and there is some stuff in there. I also checked the path settings inside Lazarus again and they the sdk- path points to /home/user/Android/android-sdk
What else can I do?
Many Thanks so far!

You need check the folder:

Created a new wiki page for LAMW Linux Installation (http://wiki.freepascal.org/LAMW_on_Linux)

Updated installation procedure to 2018-Sep-29 ver 1.1:
(see first post (https://forum.lazarus.freepascal.org/index.php/topic,40750.msg281604.html#msg281604))

1) Work arounds were needed to deal with recent NDK / Gradle changes.
2) Updated command line SDK tools to "sdk-tools-linux-4333796.zip".
3) Using newer platform and build tools (ver 26 instead of ver 25)
4) Added MIPS toolchain links to work around NDK and gradle plugin inconsistency.
5) Using new Gradle:  gradle-4.10.2-bin.zip (previous was 4.1)
6) Add new environment variable: export ANDROID_SDK_ROOT="$HOME/android/sdk"
7) Tested with newer FPCUPdeluxe version (ver 1.6.1m)

A shoutout to Handoko for his recent hard work to create a new detailed Linux installation procedure.  Thanks for sharing.
He makes some different choices than I do, but nothing wrong with that.  Its good to have choices. :-)

Wayne Sherman, and other contributors - !!THANK YOU!! for this guide. Without it I would never have been able to get Lazarus Android cross-compiles working.

Here are some notes on installing and testing the Lazarus-Android build system which might help others in the process. This was done on 2020-01-21.

My system runs Debian. Lazarus is installed on it and configured to target Debian. Since the Lazarus-Android IDE had been tested on Xubuntu 18.04 64 bit I hosted it on a VirtualBox Ubuntu 18.04 virtual machine. (Should have used Xubuntu, not Ubuntu. Next time!) This was a good thing because I had to start over more than once! Details:

- Ubuntu 18.04 LTS.
- System disk: 23 GB (default 10 GB is not enough).
- System RAM: 3072 MB (2048 MB is not enough).
- Under "Updates and other software" select "Minimal installation", deselect "Download updates while installing Ubuntu".
- When Ubuntu install is complete, run Settings application, Power-Power Saving-Blank screen-Never.

Re the last item: blanking of the virtual machine screen and/or blanking of the host machine screen appeared to cause crashes. When leaving the machines running unattended, if virtual machine had the mouse and keyboard captured that appeared to prevent blanking of the host machine screen.

- When running ./fpcupdeluxe-x86_64-linux, Basic tab, used FPC "fixes3.2" and Lazurus  "2.0.2". (The recomended "fixes3.2" "fixes2.0" resulted in failure.)

- When running ./fpcupdeluxe-x86_64-linux, Build Modules-OPM-Install module fails. Just ignored that because it is optional.

When building the APKs the correct command line is
./gradle-local-build.sh NOT
./gradle_local_build.sh

I tried installing both the "debug" and "release-unsigned" APKs on my Asus TF700T running Cyanogenmod Android 4.4.4. The "debug" version installed and ran, the "release-unsigned" did not install.

- When the app was run, the widgets were not correctly placed on the screen.

Next challenge - get the widget placement working!

Post by: JackDca on January 24, 2020, 06:23:29 pm
When I follow the instructions to build a test APK (with jtextview, jeditext and jbutton controls) the project seems to build OK. But, when I install on the target Android device, all three controls are in the upper left-hand corner of the screen. Investigating this, in Lazarus on the build machine, when I mouse over the controls, the tooltip for each control shows "Position 0,0" which is consistent with what I see on the target device. Yet if I look at the .lfm file the positions look reasonable e.g. for the jTextView control
Left = 72
Top = 49
Width = 64
Height = 19

Any suggestions?

Left = 72
Top = 49
Width = 64
Height = 19

Don't set those values directly. Instead you should configure these:
- LayoutParamHeight
- LayoutParamWidth
- PosRelativeToAnchor
- PosRelativeToParent

Hello Handoko,

OK, I studied the link that you pointed me at. I think there's some information missing.

You say to  configure LayoutParamHeight.

How? 

Is there a dialog to do this?

Do I edit a text file?

Is there an example somewhere?

Would really appreciate your guidance. I have searched through the wikis and I am not finding anything helpful.

[FAQ 2]: [Thanks to Ahmad Bohloolbandi (a.k.a. @developing) ]

#Question: How do we can design a layout that shown same in real device?

[Answer]: You should use the component properties:

      "Anchor",
      "PosRelativeToParent",
      "PosRelativeToAnchor",
      "LayoutParamHeight",
      "LayoutParamWhidth"
         
Example:

1-Put a "jTextView" component on your AndroidModule form:

   Set "PosRelativeToParent"
      "rpCenterHorizontal" [True]
      "rpTop" [True]

2-Put a "jButton" component on AndroidModule form:

   Set "Anchor" to "jTextView" (Because you should set position relative with "jTextView")
   set "PosRelativeToAnchor"
      "raBelow" [True]

3-Put a "jEditText" component on form:

   Set "Anchor" to "jButton".
   Set "PosRelativeToAnchor"
      "raBelow" [True]

NOTE:    Anchor setting is most important section of this design,
   because your component position depends on this property.
   And for change width and/or height of each components you should
   change/configure "LayoutParamWhidth" and/or "LayoutParamHeight".
Title: Re: [HowTo] Android Development Environment on Linux (FPCUPdeluxe + LAMW)
Post by: Handoko on January 27, 2020, 06:56:00 pm
@JackDca

My computer has some some minor issues, I can't run my LAMW. I'm going to explain using what I can remember.

Try to click the component you want to set its layout, for example click your "JButton1". Then in the Object Inspector, you should able to find these properties:
- Anchor
- LayoutParamHeight
- LayoutParamWidth
- PosRelativeToAnchor
- PosRelativeToParent

LayoutParamHeight and LayoutParamWidth are used to configure the size of the component. PosRelativeToAnchor and PosRelativeToParent are needed to set the position of the component. For example you want the component to be set to the center its parent, you set PosRelativeToParent := rpCenterHorizontal; And to set the y position of the component, you need the set the Anchor.

Also, you may need to set the margins.

Because Android apps need to 'look' good on any screen resolution and allow users to freely change its orientation (landscape/portrait), you do not set the component's position values directly. Instead you have to set how the component is related to the others.

Post by: JackDca on January 27, 2020, 07:36:57 pm
@Handoko and @jmpessoa,

The fact that Object Inspector is used to set the parameters was the missing piece of information. Probably obvious to you, but not to this newbie!

Thanks again.

OK, sorry to be a pest, but ...

I am now getting the following error termination when I do a Lazarus Run-Build of the "simple test project" as per Reply #2:

Messages
Verbose: Selected chip architecture: armeabi-v7a

Fatal: Cannot find system used by controls. Make sure all ppu files of a package are in its output directory. ppu in wrong directory=/home/jack/fpcupdeluxe/fpc/units/arm-android/rtl/system.ppu..

This is very strange in that I have done successful builds before. Thinking that I had perhaps corrupted something in the Lazarus setup, I restored a copy of the virtual machine that I had saved immediately after installing Lazarus (including "Path Settings"), and before doing my first successful Lazarus build. The problem is still there. I think I am doing everything exactly the same way that I did it previously, but clearly I am not.

The only idea I have had is that the Build process is pulling something from the Internet that has changed in the last few days.

Any suggestions?

OK - problem solved - after some searching on the Internet and especially this post (thanks again to @jmpessoa and other posters):

https://forum.lazarus.freepascal.org/index.php?topic=41918.0

The "Fatal: Cannot find system used by controls." message appears to be caused by a mismatch between the chipset specified when setting up Lazarus with fpcupdeluxer and the chipset specified when doing Run-Build with Lazarus.

In my first setup these appear to have been configured to match, but later the chipset for the build had changed, perhaps unwittingly by me, or perhaps because it reverted to a default.

in any case, it was fixed in Lazarus by
Project-Project Optinos-LAMW Android Project Options-Build-Chipset
and selecting ArmV7APv3 (which apparently had been changed to ArmV7A+Soft).

While there you might want to turn off most of the permissions to be requested by the application. The default is to request all permissions, which seems a bit dangerous. This is at
Project-Project Optinos-LAMW Android Project Options-Android Manifest-Permissions.

Those are great instructions, this is quite complex indeed.

I installed everything, made the test program, but when I run the emulator, the screen remains black, and at some point my computer freezes. Even the mouse cursor cannot move anymore. Then I have only the option of pressing the power buttons for 4 seconds to turn off the computer.

Ok. Hmm well then I would need to buy an Android phone.

I recommend you a Samsung phone, even the cheap ones are good. I have one with only 16gb of disk space (Samsung j5 prime, 2016 model) and I can install everything, except big games, but everything else works. With one of 32gb of space will be enough for everything else.

This is a new model, cheap but good (i'm not sponsoring, just sharing my opinion)

This is a bit old, but you can use memu or any other emulator, just need to connect it via adb:

I recommend you a Samsung phone, even the cheap ones are good. I have one with only 16gb of disk space (Samsung j5 prime, 2016 model) and I can install everything, except big games, but everything else works. With one of 32gb of space will be enough for everything else.

A friend sent me a Chinese large-screen 'phone a few months ago, and I ended up doing repeated Android reinstalls. I'm not saying that the 'phone is particularly good or bad, but the experience highlighted the necessity of (a) selecting a 'phone for which firmware images are available and (b) making sure that the processor can always be put into a "coldstart" mode where it will accept a new firmware image (none of this "locked for your own protection" lark) and that a suitable upload program for your chosen PC OS is available.

In this particular case the Phone was a King PPTV PP6000, the chip was Mediatek which has a low-level USB upload protocol baked in, and an uploader was available which ran on Linux provided that ModemManager was disabled.

Updated installation procedure to 2021-Jun-04 ver 1.4
(see first post (https://forum.lazarus.freepascal.org/index.php?topic=40750))

Changes:
Code: Text  [Select][+][-]
  1. Simplified folder structure so everything is self-contained in one folder. ($HOME/android)
  2. Using one-button LAMW install from FPCUPdeluxe. (works great, thanks DonAlfredo!)
  3. Removed old work-arounds which are no longer required.
  4. Add a new work-around for LAMW with NDK r22 and higher.
  5. Tested on newer OS (Xubuntu 20.04 64-bit)
  6. Using OpenJDK 11 (previously was using ver 8)
  7. All dev tools and utilities have been updated to more recent versions.
  8. No longer need FPC/Lazarus trunk, so using stable builds of both.
  9. Logout is no longer needed to set environment variables.
  10. Added optional script to setup environment for command line work.

  1. Removed work-around for LAMW when using NDK revision >= 22.
  2. This has been fixed in the latest LAMW git code.
  3. (Work around was incorrect anyway since the API level was needed by LAMW, not the NDK revision)

Thanks for this guidance. Without it I would have spent weeks or months getting this far.

I used fpcupdeluxe to install fpc + Lazarus + LAMW into an Android folder in my user folder. I could not compile without an error so followed these instructions.
When I got to the point below, fpcupdeluxe had already created a tools folder.
My question is: should there be a tools/cmdline-tools folder or a cmdline-tools/tools folder or both?

Code: Pascal  [Select][+][-]
  1. # download and extract Android SDK Command Line Tools for Linux
  2. # from https://developer.android.com/studio/#downloads
  3. mkdir -p "$HOME/android/sdk/cmdline-tools"
  4. cd "$HOME/android/sdk/cmdline-tools"
  5. wget "https://dl.google.com/android/repository/commandlinetools-linux-7302050_latest.zip"
  6. unzip "commandlinetools-linux-7302050_latest.zip"
  7. rm "commandlinetools-linux-7302050_latest.zip"
  8. mv cmdline-tools tools

My question is: should there be a tools/cmdline-tools folder or a cmdline-tools/tools folder or both?

It should be:  .../cmdline-tools/tools/

This can be seen from the next step (line 21):
cd "$HOME/android/sdk/cmdline-tools/tools/bin"

The tutorial assumes you are starting with an empty $HOME/android/ directory.  fpcupdeluxe is not used until after the command line tools have been installed.

Maybe is better to use  xdg-user-dir than hardcoding "$HOME/Desktop/" directory. It handles localization of the filenames.

Something like this:

Code: Bash  [Select][+][-]
  1. # note: the following lines must be copy/pasted as one line, starting at "cat" and ending at "EOF"
  2. cat <<EOF > "`xdg-user-dir DESKTOP`/Android-Command-Line.desktop"
  3. [Desktop Entry]
  4. Type=Application
  5. Icon=utilities-terminal
  6. Exec=$HOME/android/set_dev_environment
  7. Name=Android-Command-Line
  8. Terminal=true
  9. StartupNotify=false
  10. EOF
  11. chmod +x "`xdg-user-dir DESKTOP`/Android-Command-Line.desktop"

Please see the first post (https://forum.lazarus.freepascal.org/index.php?topic=40750) in this message thread.  It has been updated with the latest procedure.

but avd manager not start, run with command line

I just tested the following and it worked:

Installing and Using the Android Emulator:
(the method described here uses the command line, another method is to install Android Studio (https://developer.android.com/studio/))

Code: Bash  [Select][+][-]
  1. #Install the emulator and a system image
  2. cd "$HOME/android/sdk/cmdline-tools/tools/bin"
  3. ./sdkmanager "emulator" "system-images;android-24;default;armeabi-v7a"
  4. #(to get a list of system images use ./sdkmanager --list)
  5.  
  6. #Create an android virtual devices (AVD)
  7. #(this particular device will work with 32-bit only)
  8. ./avdmanager create avd -n "my_test_device" -k "system-images;android-24;default;armeabi-v7a"
  9.  
  10. #(to get a list of devices use ./avdmanager list devices)
  11. #(after creation, AVD files are stored in:  ~/.android/avd/)
  12.  
  13. #Run the emulator
  14. cd "$HOME/android/sdk/emulator"
  15. ./emulator -avd "my_test_device"
  16.  
  17. # (to get a list of available AVDs, use ./emulator -list-avds)
  18.  

For my test, I ran the emulator first.  Once the emulator is running, then from the Lazarus IDE menu select Run | [LAMW] Build Android Apk and Run

Added notes on emulator testing:

Testing in VirtualBox (enabled nested virtualization and 3D video)
General Warning: Do not run the Android emulator as a "nested" virtual machine within another VM environment.  It can be done, but it has issues.

If running inside a virtual machine, software rendering may be required.  Run the emulator with -gpu swiftshader_indirect. More info here (https://developer.android.com/studio/run/emulator-acceleration.html).

(Despite the warning above, this was tested in my VirtualBox AMD64 Linux VM)
This worked for testing 32-bit ARM APKs:
   system-images;android-24;default;armeabi-v7a
   ./emulator -avd "my_test_device"
  (in my current setup, this test did not require -gpu swiftshader_indirect)

Emulator images that are native arm64-v8a are so slow I haven't gotten them to boot.

For API 30 and later the x86 emulators emulate ARM (https://android-developers.googleblog.com/2020/03/run-arm-apps-on-android-emulator.html) when running on x86_64 host platform (reportedly 10 times faster than the native ARM emulators)
 
32-bit ARM APK works with system-images;android-30;google_apis;x86
32-bit and 64-bit APK works with system-images;android-30;google_apis;x86_64
./emulator -avd "api30-x86-device" -no-snapshot-load -gpu swiftshader_indirect
./emulator -avd "api30-x86_64-device" -no-snapshot-load -gpu swiftshader_indirect
For my testing with these two system images, the Android back and home buttons don't work and some system apps crash. (e.g. Settings)

Don't tire yourself so much, windows doesn't need any of this, it should be the same in linux  ;D
1- Install Android Studio
2- Make sure you can run the emulator from within Android Studio or using the launcher!!! Run it and keep it running.
3- Run your Android project using Lazarus and LAMW
4- Goto 2

No, you should not copy.
SDKs used by LAMW and Android Studio should be separate.
So, Everyone should use their own SDK.

On Android, the design is different. I recommend that you read it.

Are you compiling a 32-bit or 64-bit APK?  In my example, I used a 32-bit ARM emulator system image so I tested with a 32-bit APK.
For the emulator listening port, the terminal output says "Started GRPC server at 127.0.0.1:8554, security: Local"

On my test VM, I get the same "Android emulators" popup window only if I am not running the emulator already.  The "Refresh" and "AVD Manager" buttons don't do anything.

A close example of what you want to do; https://cadplugin.com/other/AppLAMWProject1.rar (https://cadplugin.com/other/AppLAMWProject1.rar)
For more control you should use the layout, it may take some trial and error.

From here:

Quote
[FAQ 2]: [Thanks to Ahmad Bohloolbandi (a.k.a. @developing) ]

#Question: How do we can design a layout that shown same in real device?

[Answer]: You should use the component properties:

      "Anchor",
      "PosRelativeToParent",
      "PosRelativeToAnchor",
      "LayoutParamHeight",
      "LayoutParamWhidth"
         
Example:

1-Put a "jTextView" component on your AndroidModule form:

   Set "PosRelativeToParent"
      "rpCenterHorizontal" [True]
      "rpTop" [True]

2-Put a "jButton" component on AndroidModule form:

   Set "Anchor" to "jTextView" (Because you should set position relative with "jTextView")
   set "PosRelativeToAnchor"
      "raBelow" [True]

3-Put a "jEditText" component on form:

   Set "Anchor" to "jButton".
   Set "PosRelativeToAnchor"
      "raBelow" [True]

NOTE:    Anchor setting is most important section of this design,
   because your component position depends on this property.
   And for change width and/or height of each components you should
