LAMW comes with TCP, SMTP and HTTP client components.
But I want to discover two Android devices in LAN, from the same LAMW
application. What are my options to implement UDP broadcast ? I tried
Indy (not compiling due to dependencies), lnet (compiled but app
crashes).

The mORMot has UDP support ! And runs very well on Android. See:

That would be awesome jmpessoa  Discovering devices is an important
feature in mobile development

@DonAlfredo
SynCrtSock does not compile, even when i switch directives from Linux
to Android, it is still missing units like LibC or types like TSocket.

jmpessoa, Thank you for the update with UDP component. It works
perfectly fine. I have also tested sending broadcast from Android and
received it on Windows program with IdUDPServer (Indy), and the other
way (Windows -> Android) with IdUDPClient - results without a single
problem. Thank you again for your great work.
