# LAMW Android Tutorial

I am using Windows 11, 64-bit system.

## 1. Installation Section

1. I installed **laz4android3.4-FPC3.2.2.exe** on 2024-07-17. 
   Download link: [Laz4Android](https://sourceforge.net/projects/laz4a
ndroid/files/?source=navba) 
   Reason: It has installed all the cross Android compilers: arm-
android / aarch64-android / i386-android / x86_64-android / jvm-
android. 
   If you want to install the cross compilers yourself, I haven’t
learned about that. If anyone knows, feel free to share, or you can
try using **Fpcupdeluxe** to install.

2. I installed **LAMW 0.8.6.4**. 
   Download the latest version of LAMW: 
   Link: [LAMW GitHub](https://github.com/jmpessoa/lazandroidmodulewiz
ard/archive/master.zip) 
   After extracting, copy the files to
**C:\laz4android3.4\components\**. Be careful not to misplace the
directory; I think it won't matter too much since it's just a
directory for storing components. 
   Then install the **LPK** files in this order:
   - tfpandroidbridge_pack.lpk
   - lazandroidwizardpack.lpk
   - amw_ide_tools.lpk 
   If you can’t find the files, try searching in that directory.

3. I installed **JAVA JDK 21.0.2 (64-bit)**. 
   Download link: [Oracle
JDK](https://www.oracle.com/cn/java/technologies/downloads/#java21) 
   I chose this: [JDK Download](https://download.oracle.com/java/21/la
test/jdk-21_windows-x64_bin.exe) 
   Of course, you can install this JDK as well, but I haven't tried
it: 
   [Adoptium](https://adoptium.net/]"]>Blockedrin/releases/)

4. I installed **Gradle 8.6**. 
   Download link: [Gradle Releases](https://github.com/gradle/gradle-
distributions/releases/download/v8.11.1/gradle-8.11.1-all.zip) 
   I think you can download a higher version.

5. I installed **Apache Ant 1.10.14**. 
   Download link: [Apache
Ant](https://ant.apache.org/bindownload.cgi) 
   I directly extracted it and placed it in the C drive (I believe you
can place it in any directory). I think you can also download a higher
version.

6. I installed **NDK r21e (Windows 64-bit version)**. 
   Download link: [NDK Unsupported
Downloads](https://github.com/android/ndk/wiki/Unsupported-Downloads) 
   I do not recommend downloading a higher version as I am concerned
about compatibility with the LAMW version.

7. I installed **SDK Commandline Tools** as **CommandlineTools-
win-11076708_latest**. 
   Download link: [Android Command Line
Tools](https://dl.google.com/android/repository/commandlinetools-
win-11076708_latest.zip) 
   I created a target tree at **C:\android\sdkJ21\cmdline-
tools\latest**. 
   I copied the extracted files to **C:\android\sdkJ21\cmdline-
tools\latest\bin**. 
   Open a DOS command prompt and navigate to the bin directory, then
execute: 
   ```bash
   sdkmanager "build-tools;34.0.0" "platforms;android-34" "platform-
tools"
   ```
   It’s particularly important to note that this directly impacts your
directory settings in LAMW. If this step fails, it may lead to issues
with the normal operation of LAMW (this is very important).

8. Install **Android Studio**. 
   The reason I installed it is to use its emulator. You can create a
new emulator in it and name it **PFAPI35** (we'll use this name
later). 
   Create a bat file and save the following code to execute (xxx is
your computer username) to start the emulator, so you can test without
connecting a phone: 
   ```bash
   @echo off
   echo 'Start AVD'
   c:
   cd C:\Users\xxx\AppData\Local\Android\Sdk\emulator
   emulator -avd PFAPI35
   ```

## 2. Running Section

1. Project - New Project - LAMW [GUI] Android App.

2. NDK API: 22, Min. Device API: 23, Target API: 34.

3. Select Aarch64, as the emulator I installed seems to be Android
64-bit. I assume there might be errors if it’s different, which is
very important.

4. Compile.

5. [LAMW] Build Android Apk and Run.

## 3. Congratulations!

You can now explore the mysterious world of Android!

Hi
Cool mate, well done.

QuoteSelect Aarch64, as the emulator I installed seems to be Android
64-bit.Если у вас компьютер на архитектуре x86_64, то и эмулятор надо
выбирать этой же архитектуры. При этом надо помнить, что собирать
проект надо именно по эту архитектуру или сразу под несколько, но чтоб
данная архитектура поддерживалась в сборке.

Для поддержки большинства устройств желательно делать сборку для 4-х
архитектур: x86, x86_64, arm32 и arm64 (aarch64).

--------------------------------------------
Google translate:
If you have a computer with the x86_64 architecture, then you should
choose the emulator of the same architecture. At the same time, you
should remember that the project should be built for this architecture
or for several at once, but so that this architecture is supported in
the build.

To support most devices, it is advisable to build for 4 architectures:
x86, x86_64, arm32 and arm64 (aarch64).

Please tell me how to do this, I need details of the process, thanks!

gary, я не могу в данном случае помочь, я занимаюсь немного другим
направлением Android. И у меня настроено всё для сборки сразу 4-х 
архитектур. Спросите у разработчика LAWM как это можно сделать.

Google translate:
gary, I can't help in this case, I'm working on a slightly different
area of ​​Android. And I have everything set up to build 4
architectures at once. Ask the LAWM developer how to do this.

IMHO, you have to sort this out first.

You can use Google's adb.exe tool to check if the phone is connected.

Find it's location, open command prompt and use it like this (change
path to wherever is your adb located):
Code: Text  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
C:\LazarusLAMW_2024-02-06\sdk\platform-tools\adb devices
You are probably getting this:
Code: Text  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
C:\>C:\LazarusLAMW_2024-02-06\sdk\platform-tools\adb devicesList of
devices attached  C:\>
Check your USB cable and if you turned on USB debugging on the phone.
After connecting, you may also need to allow access from computer to
the phone (you do this on the phone).

Sometimes I got 'error: device unauthorized' - then I either put phone
mode to 'charging only' and phone then asks me if I allow access or I
turn USB debugging off and then again on.

Anyway, you need to have this before you will succeed on installing
apk on the phone:
Code: Text  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
C:\>C:\LazarusLAMW_2024-02-06\sdk\platform-tools\adb devicesList of
devices attachedRFCW381CNWW     device  C:\>

PACKAGE (incompatible), XIAOMI REDMI 11

Try this: go to menu Project, Project Options and '[LAMW] Android
Project Options', click tab 'Build' and there select 'Aarch64'
chipset.
Try to build and install again.

THANKS dseligo  ,

My first Goal was to use the EMULATOR come with the ANDROID SDK
package, after your post i have found that this emulator is an 
X86_64, i have put this configuration in the project option, and all
is allright now !!!

My Second goal was to use on my tablet TECLAST P20HD(AARCH64),  i
activate the DEV mode and authorizing the usb debug, all is allright
!!!

My third goal is to instal on my phone, my phone is a xiaomi REDMI 9T
(AARCH64), after put my phone un DEV mode and authorizing the usb
debug, my phone wouldn't install the package, i have search and found
an option on it, you must have a XIAOMI ACCOUNT and authorizing
"INSTALL FROM USB" from the "DEV" menu, now all is allright !!.

I will try soon on ZEBRA MC9300.
