Hey guys, I am back! And with a question: Can I run a processing program in my PC that detects the proximity of my android smartphone? And use this proximity data to run a sketch in my android? I mean probably both should be running, like: (PC) proximity>5, runs video/ (Android) Proximity<5, runs video. Well, like a program that runs in PC and android using the same data (Bluetooth). I read about Ketai, and I think it's a good start....

Getting ready stable release of Android mode
Hello everyone,
I'm aiming to release the stable 3.0 version of the Android mode sometime soon. Right now there is a "Release Candidate" version available, so if you want to try it out to see if there are any major issues, please get it either through the Contribution Manager, or download it manually from the GitHub releases page:

Thank you!

HTTP-Requests library on Android, FATAL EXCEPTION issue
i'm testing with really simple android app which save the captured image then upload to the server on each time during the http post session the app got crashed,reported as following:

Picture Server/Sender
For my design project I need to make an application that can make pictures and from there send them to a server (a map or something on a computer). From there it needs to be** sended to a tablet** that displays all the pictures that are stored in the server in a** slideshow**. I'm not even sure if this is possible in processing. I can really use some of your guys help.
Thanks!

Low frame rate on Android
Hello
I run a sketch that makes 180 ellipses rotating around a point. each of those ellipses are instances of a Satellite Class that render the ellipse using pushMatrix(), translate(...), rotate(...) and ellipse(...)
Running this sketch on my pc , the FPS is stuck at 60, but running it on my Nvidia Shield K1, I get around 30 FPS
-1- is it that demanding to run 180 objects using primitive shapes ?
I tried with a little more complicated shapes, using 4 primitives, it gets to 22 FPS
I tried using PShape to build Shapes of 4 primitives and it gets to 18 FPS
-2- Am I facing a weakness in Processing for android ?
-3- Is there a way to solve that ?
(I tried using P2D and it crashes with "A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x9e5ad000 in tid 17144 (GLThread 46915)" message)
cheers
update: using a 50x50 PGraphics instead of PShape gets me 11 FPS
update 2: I finally got it to run on P2D (I don't know why, I just copied my whole code, classes and all, to a blank app that was running P2D just fine) and here is the result:
with my 180 satellites being mere ellipses my FPS is 25 :(
is anybody here ?

Can't use the method lights() or directionalLight() in my drawing.
All the time I try to use some light releted method like lights() or directionalLight() the console is returning to me the error FATAL EXCEPTION: GLThread 10295 java.lang.NullPointerException. Can someone tell me what could it be?
the drawing method:

lights(); //because of the method the error happens...
float tempOrientation = (float) ((int) (accelerometerY * 1000)) / 1000;

How to send HTTP POST containing JSON body
I'm trying to use the 'HTTP Requests for Processing' library, but it seems to be specifically tailored to sending form-encoded requests. Is anyone able to use this to make calls against a REST API with JSON content?

FX2D & Android
Testing my sketch on PC, I see that the FX2D render just blows everything in terms of performance
So I spontaneously think that this is the renderer I need to use for the Android version of my sketch... but FX2D is not available on Android.
Yet I see links ( 1 and 2 ) explaining that javaFX can work good in Android.
Wouldn't it make sens to try that ?
Anyone with experience in that ?

Error 2 -> Ubuntu 14.04 + Processing 3.0b5
Hi there,
I have a problem running processing in linux. Ubuntu is my only OS, so no other systems installed (Winodws or similar). I belive I have Java correctly installed. If I enter echo $JAVA_HOME, I get the right answer -> /usr/lib/jvm/.
If I check in console the java version I get this java version "1.7.0_95" OpenJDK Runtime Environment (IcedTea 2.6.4) (7u95-2.6.4-0ubuntu0.14.04.2) OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode)
If I check javac version -> javac 1.7.0_95
If I try to compile a simple sketch in processing, I get Error 2 -> JAVA_HOME is set to: /home/gorazd/Dokumenti/processing-3.0b5/java
I'm trying to figure it out why is Processing trying to get java from other location ?
Update it if necessary, or manually execute the following command: /home/gorazd/Dokumenti/processing-3.0b5/java/bin/keytool -genkey -alias AndroidDebugKey -keyalg RSA -dname "CN=Android Debug,O=Android,C=US" -validity 10950 -keypass android -keystore
This statement fails miserably, there is no keytool in this directory.
I have to state, that I'm not a Linux power user - I'm still a rookie and my linux knowledge is very limited. So If there is anyone kind enough to give me some step by step answer / help I would very appreciate.
Regards.

I needed to bet text input for a sketch on a mobile device that I'm making and ended up making my own keyboard that adjusts to whatever resolution it's displayed on (including when the user changes orientation of course).
