Lazarus 1.8.0RC5 + LAMW
« on: October 31, 2017, 06:29:05 pm »
-edit-:
This installation tutorial no longer works with the latest version of NDK/SDK.
Please use this new installation guide: http://forum.lazarus.freepascal.org/index.php?topic=42527




Hello, I'm back for Android programming.
Today I tried to install LAMW on Lazarus 1.8.0RC5 and it succeed! :D

So I write this tutorial, maybe someone will find it useful.

Before You Start

Remember, you should do proper backup before you start.

Linux users can use this script:
https://github.com/jmpessoa/lazandroidmodulewizard/tree/master/docs/linux
I tested the script but I prefer my way to install because I don't want multiple versions of Lazarus/FPC put on my computer.

More documentations can be found here:
https://github.com/jmpessoa/lazandroidmodulewizard/tree/master/docs

=== Environment ===

This tutorial should work on other environments with no or some changes but I only tested on:
- Ubuntu Mate 17.10 64-bit
- Intel x64
- Lazarus 1.8.0RC5 FPC 3.0.4 x86_64-linux-gtk2


This tutorial assume you're using NDK revision 11c. If you're not using this version, you have to change all the texts "4.9" below accordingly.

=== Install Necessary Libraries & Tools ===

On my system I only need to use Terminal to install these:
01. sudo apt-get install subversion
02. sudo apt-get install android-tools-adb ant openjdk-8-jdk


I saw on other tutorials, they said you may also need to install:
03. sudo apt-get install freeglut3 freeglut3-dev libwxgtk3.0-0v5
04. sudo apt-get install libgtk2-gladexml-perl libgtk2.0-bin libgtk2.0-cil
05. sudo apt-get install make build-essential libncurses5-dev libtinfo-dev
06. sudo apt-get install libcairo2-dev libpango1.0-dev libatk1.0-dev libghc-x11-dev
07. sudo apt-get install libgtk2.0-dev libgdk-pixbuf2.0-dev libgpm-dev fakeroot


=== Prepare Android NDK & SDK ===

08. mkdir ~/Android
09. Extract Android NDK https://developer.android.com/ndk/downloads to ~/Android
10. ln -sf ~/Android/android-ndk-r11c ~/Android/ndk
11. cd /usr/bin
12. sudo ln -sf ~/Android/ndk/toolchains/arm-linux-androideabi-
4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-as arm-linux-androideabi-as
13. sudo ln -sf ~/Android/ndk/toolchains/arm-linux-androideabi-
4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-ld arm-linux-androideabi-ld
14. sudo ln -sf /usr/bin/arm-linux-androideabi-as arm-linux-as
15. sudo ln -sf /usr/bin/arm-linux-androideabi-ld arm-linux-ld
16. Extract Android SDK https://developer.android.com/sdk to ~/Android
17. ln -sf ~/Android/android-sdk-linux ~/Android/sdk
18. Install SDK Packages by running ~/Android/sdk/tools/android

Note:
The "android" tool has been deprecated by newer version of Android SDK, read more:
http://forum.lazarus.freepascal.org/index.php/topic,38777.msg281267.html#msg281267

19. Use a text editor to open ~/.bashrc and add this text below:
export PATH=$PATH:~/Android/ndk/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin

Note for #18:
I only enable Android 4.4.2 (API 19), you can try other version if you want.

=== Cross Compile Android ARM ===

20. cd /usr/share/fpcsrc/3.0.4
21. sudo make clean crossall OS_TARGET=android CPU_TARGET=arm
22. sudo make crossinstall OS_TARGET=android CPU_TARGET=arm INSTALL_PREFIX=/usr
23. sudo ln -sf /usr/lib/fpc/3.0.4/ppcrossarm /usr/bin/ppcrossarm
24. sudo ln -sf /usr/bin/ppcrossarm /usr/bin/ppcarm
25. Add these blue lines below to /etc/fpc.cfg:

#IFDEF ANDROID
#IFDEF CPUARM
-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget
-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget/*
-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget/rtl
#ENDIF
#ENDIF


=== Cross Compile Android i386 ===

You can skip this section if you do not need to target Android Intel CPU.

26. cd /usr/bin
27. sudo ln -sf ~/Android/ndk/toolchains/x86-
4.9/prebuilt/linux-x86_64/bin/i686-linux-android-as i686-linux-android-as
28. sudo ln -sf ~/Android/ndk/toolchains/x86-
4.9/prebuilt/linux-x86_64/bin/i686-linux-android-ld i686-linux-android-ld
29. sudo ln -sf /usr/bin/i686-linux-android-as i686-linux-as
30. sudo ln -sf /usr/bin/i686-linux-android-ld i686-linux-ld
31. cd /usr/share/fpcsrc/3.0.4
32. sudo make clean crossall OS_TARGET=android CPU_TARGET=i386
33. sudo make crossinstall OS_TARGET=android CPU_TARGET=i386 INSTALL_PREFIX=/usr
34. sudo ln -sf /usr/lib/fpc/3.0.4/ppcross386 /usr/bin/ppcross386


=== Lazarus Android Module Wizard Installation ===

35. cd ~/Android
36. svn co https://github.com/jmpessoa/lazandroidmodulewizard.git
37. ln -sf ~/Android/lazandroidmodulewizard.git ~/Android/lazandroidmodulewizard
38. Start Lazarus IDE
39. menu > Package > Open Package (.lpk) > "tfpandroidbride_pack.lpk"
40. Compile, then and Use > Install
41. menu > Package > Open Package (.lpk) > "lazandroidwizardpack.lpk"
42. Compile, then and Use > Install
43. menu > Package > Open Package (.lpk) > "amw_ide_tools.lpk"
44. Compile, then and Use > Install
45. menu > Tools > [Lamw] Android Module Wizard > Paths Settings: [Jdk, Sdk, Ndk, ...]:

Path to Java JDK: /usr/lib/jvm/java-8-openjdk-amd64
Path to Ant bin: /usr/bin
Path to Android SDK: /home/[handoko]/Android/sdk
Path to Android NDK: /home/[handoko]/Android/ndk
NDK Version: 11c


Note for #39, #41, #43:
Those lpk files can be found inside "lazandroidmodulewizard.git" folder.

Note for #45:
You should change the name "[handoko]" to the user name on your computer.

=== How To Start A LAMW Project ===

Lazarus main menu > New > Project > choose one of these:
- Android [NoGUI] JNI Module [Lamw]
- Android [GUI] JNI Module [Lamw]
- Android Console App [Lamw]

The components you can use in LAMW Projects are limited on the those inside "Android Bridges" and "Android Bridges Extras" tabs only.

The pascal source code will be saved in: [projectname]\jni.
The compiled binary (*.so) will be saved in: [projectname]\libs (inside armeabi or x86)
The Android binary (*.apk) will be saved in: [projectname]\bin

To produce the apk file (from *.so), you need to run "build-debug.sh" or "build-release.sh", which can be found on the project folder. Alternatively, you can you use LATE (Lazarus Apk Expert Tools):
Lazarus main menu > Tools > [Lamw] Android Module Wizard > LATE: Apk Expert Tools [Build, Install, ...]


Below I provided an apk sample compiled to target ARMV7A, it should run correctly on Intel CPU too. It shows some moving rectangles drawn using OpenGL ES 2 (jCanvasES2). The source code can be downloaded here:
http://forum.lazarus.freepascal.org/index.php/topic,38777.msg264878.html#msg264878

Note:
LATE does not work correctly on Linux.

=== Setting For Android i386 Target ===

You need to make some changes if you want to target on Android i386.

46. Lazarus main menu > Project > Project Options > Paths > Libraries (-Fl):
/home/[handoko]/Android/ndk/platforms/android-21/arch-x86/usr/lib/
47. Lazarus main menu > Project > Project Options > Paths > Target file name (-o):
../libs/x86/libcontrols
48. Lazarus main menu > Project > Project Options > Config and Target > Target file name (-P):
i386
49. Lazarus main menu > Project > Project Options > Custom Options:
-Xd -XPi686-linux-android- -FD/home/[handoko]/Android/ndk/toolchains/x86-4.9/prebuilt/linux-x86_64/bin

Note:
To make fat binary (https://en.wikipedia.org/wiki/Fat_binary), compile as much target as you want before running that build debug/release script. To cancel fat binary producing, delete all things inside [projectname]\libs folder before compiling.


---Edited---
04-Nov-17:  Cross Compile Android i386 section, sample-apk.zip and screenshot.
31-Mar-18:  Step #18 - info about depreciation of "android" tool.

LAMW (Lazarus Android Module Wizard) is one of the way to create Android app using Lazarus. So far, there are several ways to do Android programming in Lazarus, LAMW is the easiest I think.

There other options are:

- FPC JVM
http://wiki.lazarus.freepascal.org/FPC_JVM_Android_Development

- Laz4Android
This package uses Custom Drawn Interface.
https://sourceforge.net/projects/laz4android/

- LazToApk
This tool will help you automatically download Laz4Android, Android SDK & NDK, configure and perform cross compiling.
https://sourceforge.net/projects/laztoapk/

- LazSDL2Design Package
Similar to LAMW, it has its own Form Designer and components.

So I write this tutorial, maybe someone will find it useful.

Hello Handoko!
Great! I wil add your tutorial to LAMW repo...

Laz4Android + LAMW  is good, too!

Thank you!

For your info, I have included two screenshots of a simple Android app that I am currently working at.

It scans barcodes and stored them in a mORMot database (local and remote).

LAMW "maps" allmost all native Android GUI controls APIs.
So, the "look" will depend on the design skills...

I modified the code a bit, adding more rectangles and change the background color when jButton2 clicked.

I wrote the code originally to test jCanvasES2 can or not to handle deep test (glEnable(GL_DEPTH_TEST)) because I found some things not working correctly.

The big rectangle will slowly move to the back, it starts at its z position above the small rectangles and when it reached the middle of the screen, the big rectangles will be behind the small rectangles.

I don't need this code anymore. It is free, I put it in CC0. You can do anything you like with the code.

Although I set the compiling parameters to target ARM devices, it still working correctly on my Intel-based mobile phone. Some maybe interested to know, I done a massive benchmark on my Intel-based phone using this rectangle code (with some modifications) and this is the result:

Target CPU (-P)    Method 1     Method 2
i386               980 frames   984 frames
arm                740 frames   739 frames


It is 20-30% slower running ARM codes on Intel machine.

Below are the settings I used to compile the code:

NDK API level: 21 (Android 5.0, 5.1)

Thanks for the installation help.

Regarding step #18:
18. Install SDK Packages by running ~/Android/sdk/tools/android
Note for #18:  I only enable Android 4.4.2 (API 19), you can try other version if you want.

The "android" tool has been deprecated and instead this tool should be used:
~/android/sdk/android/bin/sdkmanager

BTW, I used this to get a list with full package names yet compact (from here):
./sdkmanager --list --verbose | grep -vP "^Info:|^\s|^$|^done$"

I have attached the list of packages.  Which packages do I need to install at a minimum? (platforms;android-19 ?)

Thank you.

I admit I'm lazy when things already work so I haven't updated my Android SDK/NDK for a long time.

Thank you for the information about the depreciation of "android" tool. I have added some note on the step #18.

What about "Android-25" + "Buil-Tools" 25.0.3 + Gradle 4.1....  so, you can stay prepared to incoming LAMW 0.8 !!

Based on the list provided by "sdkmanager", installation would be like this:
./sdkmanager "platforms;android-25" "build-tools;25.0.3"

Some questions please:
1) sdkmanager doesn't list anything with "Gradle" in the name.  Is that installed with the build-tools package?
2) If I install android-25, will my compiled app still work on earlier versions of Android?
3) Does LAMW 0.7 work with android-25?

Thanks for your assistance
