Hello, I installed lazarus for android using Fpcupdeluxe. After
following the wiki, I got this error when I try to build and run apk
(ctrl+F1). See Image attached.
Also I attach the a image with android module wizard.

Thanks for your help in advance

Wiki page about installation of FPC and Lazarus provides incomplete
instructions about installation of LAMW (Lazarus Android Module
Wizard):
Quotehttps://wiki.freepascal.org/fpcupdeluxe
Installation of FPC and Lazarus
You need to do the following steps.
Step #1.
At first you need to install “Android Studio”.

Step #2.
Open “Android Studio” and manually install needed versions of Android
SDK and Android NDK.
Today you need SDK API level 35 and NDK 21.4.7075529.

Step #3.
Download and install manually “jdk-21”.

Step #3.
Run setup of fpcupdeluxe_v2.4.0f and press button “LAMW” which
installs stable versions of FPC and Lazarus and LAMW.

Step #4.
By default fpcupdeluxe almost always installs wrong version of gradle,
which does not work and fails to compile Android project.
Go the page
https://services.gradle.org/distributions/
and download “gradle-8.14.3”.
Go to the directory
C:\fpcupdeluxe\ccr\lamw-gradle
und unzip “gradle-8.14.3” into this directory.

Step #5.
Open Lazarus and go to menu
Tools -> [LAMW] Android Module Wizard -> Path settings [Jdk, Sdk, Ndk,
…]

Set the following paths:
QuoteC:\Program Files\Java\jdk-21
C:\fpcupdeluxe\ccr\lamw-ant\apache-ant-1.10.12\bin
C:\fpcupdeluxe\ccr\lamw-gradle\gradle-8.14.3
C:\Users\username\AppData\Local\Android\Sdk\ndk\21.4.7075529
C:\Users\username\AppData\Local\Android\Sdk
Step #6.
Go to the directory
C:\fpcupdeluxe\fpc\bin\x86_64-win64
Open file „fp.cfg“.
Change its contents to the following

following:
#         <n> : compiler stops after <n> errors (default is 1)
#         w   : compiler stops also after warnings
#         n   : compiler stops also after notes
#         h   : compiler stops also after hints

# Optimizer switches
# -Os        generate smaller code
# -Oa=N      set alignment to N
# -O1        level 1 optimizations (quick optimizations, debuggable)
# -O2        level 2 optimizations (-O1 + optimizations which make
debugging more difficult)
# -O3        level 3 optimizations (-O2 + optimizations which also may
make the program slower rather than faster)

values

Thanks you for the long answer. I'll try it
