Lazarus LAMW on Ubuntu 20.04
lazarus / 43-Android

I've installed Lazarus + FPC + LAMW using fpcupdeluxe using stable for
both FPC and Lazarus versions.  Additionally, I've installed android-
ndk-r23b in my home directory.  I created a new GUI Android module
project and went to Android Bridges and selected a button to place on
the form.  It returns an error dialog:

Error moving component jButton1:jButton
And has a cancel button

In Messages it reads:
unit1.pas(12,35) Error: unit not found: AndroidWidget

What am I doing wrong?

These are the paths in the config:
/usr/lib/jvm/java-8-openjdk-amd64
/home/sketch/fpcupdeluxe-lamw/ccr/lamw-ant/apache-ant-1.10.12/bin
/home/sketch/fpcupdeluxe-lamw/ccr/lamw-gradle/gradle-7.3.1
/home/sketch/android-ndk-r23b
/home/sketch/Android/Sdk

Hi, sketch!

unfortunately something went wrong in your installation....


Maybe you can get LAMW from here:

https://github.com/jmpessoa/lazandroidmodulewizard/archive/refs/heads/
master.zip


And replace on your LAMW system stuff....


Alternatively, you can try "LAMW Manage"

Thank you!  I installed using the LAMW Manager and it is working.  Now
under the Android Virtual Device Manager when I select the Target as:
Android 11 - API Level 30

Under CPU/ABI it shows
No system images installed for this target.

Where do I install system images so I can do Build APK and Run and it
will give me a simulation?  Or do I need to connect an Android device
for that to work?

Thank you!

You can compile and build the APK without a system image.  But if you
want to test it on an emulator, you need to install a system image. 
If you have sdkmanger command line program installed (for example,
mine is in "~/android/sdk/cmdline-tools/tools/bin") you can list
available emulator images: Code: Bash  [Select][+][-]window.onload =
function(){var x1 = document.getElementById("main_content_section");
if (x1) { var x = document.getElementsByClassName("geshi");for (var i
= 0; i ./sdkmanager --listYou can install one like this:
Code: Bash  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
./sdkmanager "emulator" "system-images;android-24;default;armeabi-v7a"

(you can also use Android Studio to install emulators and system
images)
