Endo, thanks for testing it.

It still won't install on my Galaxy Nexus with 4.2.2.

AdrianS: do you have a previous version already installed? What is 
the installation error message?

It's a very nondescript message - "App not installed"

The only reasons I can think of for that issue are:
1) Not enough internal memory available for new apps.
2) You have a debug version of the same app already installed.

Also, you might want to check if you have allowed installation of 
apps from "unstrusted sources". You need to have that option checked 
to be able to install apps coming from outside of the PlayStore.

untrusted sources

works again on my htc sensation 4.0.3

Nenad, I've installed all kinds of apps by sideloading. Even one 
from you a while back, where the app ran, but all it showed was "Hello" 
as the title of a screen with no other content. Not sure what the 
difference is with the latest one you linked.

The difference is that the new one is supposed to work. :-) Have 
you uninstalled the previous one? (It was most probably a "debug" 
version you had while the new one is a "release" version, this is 
one of the cases where the installer would block the new app installation)

on my HTC, I even don't know how to uninstall. I just download, choose 
to launch, it says previous version is going to be removed, then 
I install, run, and it is ok ...

I've uninstalled any earlier apps from you. Do you still have that 
earlier one around just so that I can see if that one, at least, 
will install?

Just re-downloaded it - it now doesn't work either.

AdrianS: does R3/Droid work for you? Not sure it would help Doc, 
but maybe he could check on some things with Cyphre?

Yeah, R3Droid works

But it was installed earlier - maybe if I tried to install it now 
it would fail. I just installed some self-built apps the other day 
though, so I'm not sure what could be the problem.

Tried to build an app just now with Processing and launched it on 
the phone with no problem.

AdrianS: you would need to have a look at the logcat output to diagnose 
the issue. You can do that with ADB if you know how to use it, else 
the simplest way is to use one of the logcat viewing apps, like this 
one:

https://play.google.com/store/apps/details?id=org.jtb.alogcat&hl=en

I don't have the old one. I will release the demo app source very 
soon, so you'll be able to recompile it fully and test locally.

Pekr: I doubt that Red port on Android and R3/Droid have much in 
common. Though, as there's no R3/Droid source released, I can't be 
entirely sure.

R3/Droid is most probably using a NativeActivity container, while 
Red relies on a Activity one.

Also, R3 relies on the gcc toolchain, while Red has its own unique 
one. So, there's not much to share there.

Dockimbel - I thought so, my idea was, that Cyphre used some ELF 
support from Adrian too ... or who did it ...

Works fine on my Android 4.1.2.

However, and I think you already know this, working with decimal 
numbers makes it close and go away.

2.0 - 1.0 ;crash

Pekr: I strongly doubt that Cyphre is using Red's ELF emitter while 
compiling with gcc. ;-)

Bo: yes I'm aware of that, currently Red supports only armel ABI 
while it seems that armhf is required for Android.

The difference between those two ABIs is the way float arguments 
are passed on sub-routine calls, IIRC, armel requires the argument 
to be on stack while armhf passes them by registers.

It's not a big task to add armhf support to the ARM backend, probably 
2-3 days of work.

Okay, AdrianS install problem is solved (debug vs release version 
signature conflict). So, so far, no reported issues with the new 
Red APK! :-)

Red has no floating point yet, only Red/System

Unless there's float support in the pending code

No, there's not.

Yessssssss !!!!! on Galaxy Note II 4.1.2

Great! Thanks for testing! :)

either I have mess again on my system, or there's a compilation error 
for me, when trying to do:


do/args %red.r "-dlib -v 0 %red/bridges/java/hello.red -o %../red/bridges/java/hello" 


Script: "Red/System IA-32 code emitter" (none)
*** Compilation Error: missing argument

Yes, the bridge updates have not been commited yet, I'm still working 
on cleaning it up. It should be ready in about an hour I hope.

ok, good to know, moving home from work, will try in the evening 
....

Just found out how to set a black (ICS) skin for Red apps on Android. 
Looks great! :)

Is it still true that Red/System doesn't support loading/reading 
files?

No, it does with my bindings

That's right, you have a C Language binding to do that, don't you?

Yes, and a cURL binding for network files

I'm trying to load binary data to perform some bit-level operations 
on it.

There's a binary example in my 6502 emulator, where it loads a ROM 
file

http://red.esperconsultancy.nl/Red-6502/dir?ci=tip

It sure would be nice if we had a centralized repository for Red 
and Red/System examples, like we have for Rebol at Rebol.org.

That wouldn't scale, unless it were a repository of links

The file operation is in machine.reds under the ROM heading

Is possible an bridge from red to App Inventor components ? https://sites.google.com/site/mobileprogrammingusf/java-bridge
