I don't develop games either, but for FPC developers their tools for 
"building and packaging your programs for various platforms" seems to be 
something to pay attention to!

Small correction, the link should be:

  https://github.com/castle-engine/castle-engine/wiki/Build-Tool

(final "l" was missing from the URL). Our instructions how to setup
environment (FPC + Android SDK, NDK) may also be useful,

parts in Java, but you can write that too in FPC, right? I mean, using 
the FPC JVM compiler. But you need to interface JVM and native code like 
you do with Java code.



even is possible visual remote-debugging
from Lazarus (but that requires many IDE modifications).

wow, any link describing how to achieve that?

Work in progress.


I am looking forward to more information here! :)

[fpc-pascal] Smartphone apps in FPC

[donald . pedder]

Hi all,

   I was on this list years ago, and then fell off at some point for
some reason, but back again now. :-)

   Having written for DOS all those years ago, I am now just getting
into making smartphone apps, and it would be good to be able to use my
old friend FPC for it. :-) I have some familiarity with Java, so
learning Android not too difficult (just gotta get around the
smartphone-specific knowledge), but I don't know Apple's language at
all, and I do want to make my apps available in both Google and Apple
stores. I understand Apple have relaxed their attitude towards
third-party developer tools in recent years, though I have also heard
they frown on some (plus doing it with FPC may be taking me into an
area where not so much tutorials available as there are for
Java/Swift). Want to be sure my apps don't get rejected from Apple
store for such a reason.

   So, just looking for some feedback from anyone on this list who
may have used FPC for Android/Apple apps. i.e. have you written in FPC
and succeeded in getting into Apple store, etc.? I'm looking to make
my decision soon as to which language to use soon, and if FPC is
suitable then that saves me having to learn a new language for the
project. :-)

thanks,
  Donald.

That would be great. I would love to read them (I am at the soaking-up
information stage :-) ).

But you don't own a smart phone and have never heard of 'long click'
like in android.view.View.OnLongClickListener ^^

Probably is possible to use FPC JVM, but I don't have time for this (yet).
Currently in my "production" project is used Java frontend and FPC backend
(communication by JNI) as client and FPC(Linux)/Delphi(Win) as Server.

Ad: in both cases (client and server) is used ofc mORMot framework

I am looking forward to more information here! :)

There are 2 possible approaches:

- Use the NDK, and then basically you're writing a native Linux application.
  You can try to use the Android SDK through some JNI tricks; but I am
  unsure how well this works.

- Use the Android SDK, using the JVM compiler.

I have written several articles on how to use the latter approach; 
I wrote a real-world app with it. 
I can send a URL for the articles if you want.

You are right, they are not.
They are only useful to access strange chars like "0"-"9" or "!@#$%&*?/ etc." 
which are not often used in passwords or user names. But of course it depends 
on the used virtual keyboard and the chars can be accessed in other ways.
I am sure you really never encountered 'long clicks' (no irony or sarcasm here) 
and you never really looked too deep into the API Guides about Android UI 
that's what amazes me.

Jackson (external) and HttpURLConnection (part of the API) do the trick very 
easily but I know nothing about how FPC accesses API classes and even less how 
it can use external Java libs (fcl-json could not be used?).

I apologize if I did offend you.

R.

Tip of the day: There is no double click listener in Android.

No.


Perhaps the concept is not as clearly identifiable as I thought or Google has 
hidden the OnLongClickListener interface too well.


I honestly never encountered it. I didn't look for it either, of course.


It's also amazing that 'not owning' a smart phone was just an excuse as you 
clearly have interacted with smart phones (yes, even emulated ones count).


I really don't see that.

I have never used a smartphone, and on the emulator all I had to do was
swipe and click to test my program. Basically it was a bunch of listviews 
to select a particular list, and a listview with some checkboxes embedded. 
In the username/password dialog, I could suffice with regular keys.


Hardly a shocking interface, and as such 'long clicks' didn't enter the picture 
at any point...

The biggest stumbleblock (and even so) was parsing JSON and sending JSON to a 
server.
