The problem is almost certainly due to sharing the same data.

Each window has its own event-processing-thread which is responsible for running its own draw method. These threads run asynchronously (i.e. independently). so the draw method can be interrupted at any time to process the other thread including its draw method.

So if you are updating shared data during the main-window draw method this could be interrupted mid-update to draw in the second window. Of course the second window is now working with partially updated data so flickers.

This would explain why having a second copy of the array does not flicker.

There are a number of techniques you could use including semaphores and locks but since you are not getting concurrent access exceptions you might be able to get away with a simple boolean semaphore.

Create a boolean variable e.g. data_locked which is set to true when you start updating the array and set to false when the update is complete.

Since you are updating the data in the first window's draw method then you only have to test the flag in the second e.g.

public void draw(){
  if(data_locked){
    return; // skip this render
  }
  // your code here
}

If this doesn't work you will need to try a different technique.

Hi, everyone. I am now trying Processing android mode. But cant build a simple sketch.

I am on windows 7 64x and a Huawei phone with android version 4.4.4

I used p5 version: 3.3.7 And the android mode version: 4.0.1

The android sdk environment is: Google Repository 58.0.0
google usb_driver 11.0.0
Android SDK Build-Tools 26.0.2
Android SDK Platform 26 2
Android SDK Build-Tools 26.0.3
Android Support Repository 47.0.0
Android SDK Tools 26.1.1
Android SDK Platform-Tools 27.0.1

I just test the simple example:Basic-Color-Brightness I didnt modify any code but it cant run on the device

the console shows:

    Build folder: C:\Users\User\AppData\Local\Temp\android5727509137112162348sketch
    :app:preBuild UP-TO-DATE

There are more info but too long for the text area of this forum...so I post a screenshot below: https://photos.app.goo.gl/8HvxdZZgXYHF69xE6

My understanding of 2d metaballs is you loop through every pixel in an array and measure the distance of each pixel to every particle and depending on the distance you give that pixel a value. However, this means you are running dist() function for every particle, for every pixel. Meaning a 600x600 square with 1000 particles is 360 million dist() checks plus the other formulas you need to get the value, which could easily be a billion lines of code to render 1 frame. Is there some method to do those checks in clusters and maybe there is a totally different way to do metaballs which can use the graphics card or concurrent processing? What is the most efficient way to render a point cloud?

Well, I don't know.

It is an "array" error (ArrayIndexOutOfBoundsException), and you only have so many arrays addressed by this function. Further, it is an "index" error (ArrayIndexOutOfBoundsException), and you only pass array index arguments at certain times -- that should narrow it down to only a few lines.

Maybe try debugging those lines? Add try / catch? You know the exact error name, so you could catch it....

• https://processing.org/reference/catch.html

For one example, you are not passing in locationsglobal as an argument and then returning an updated version, which might be cleaner. Could there be some kind of racing or concurrent modifying happening there?

Of course, it could be something else -- but that is a way to start narrowing it down....

Solved it by installing updates suggested by android studio Hi, I just tried to build the basic example in http://android.processing.org/tutorials/getting_started/index.html processing version : 3.3.6 installed Android studio 3.0.1 and its Sdk . I tried building a project with Apache Cordova and ionic and it works. but processing does not ! it failed with the following error :

If you are using NDK, verify the ndk.dir is set to a valid NDK directory. It is currently set to /home/bahha/Android/Sdk/ndk-bundle. If you are not using NDK, unset the NDK variable from ANDROID_NDK_HOME or local.properties to remove this warning.

hey, im trying to add Objects into an arrayList that is a part of a class, from a second Papplet,(when the user click the mouse, add a new Obj). But it doesnt work properly, an concurrent modification exception is crashing the sketch:

here the code:

the main scene 3D

System s;
PWindow w;
void settings() {
  s = new System();
  size(500, 500, P3D);

}

void setup() {
  background(0);
  s = new System();
  w = new PWindow();
}

void draw() {
  background(0);
  pushMatrix();
  translate(width/2, height/2);
  s.run();
  popMatrix();
}

class System {
  ArrayList<Obj>o;
  System() {
    o = new ArrayList<Obj>();
  }

  void addObj(float x, float z) {
    o.add(new Obj(new PVector(x, 0, z)));
  }


  void run() {
    for (Obj obj : o) {
      obj.display();
    }
  }

}

class Obj {

  PVector pos;

  Obj(PVector o) {
    pos = o.get();
  }

  void display() {
    pushMatrix();
    translate(pos.x, pos.y, pos.z);
    sphere(100);
    popMatrix();
  }
}

the second Papplet , when the user click the screen, add a new Obj

    class PWindow extends PApplet {

      PWindow() {
        super();
        PApplet.runSketch(new String[] {this.getClass().getSimpleName()}, this);
      }


      void settings() {
        size(500, 500, P2D);
      }

      void setup() {
      }

      void draw() {
        for(Obj o : s.o){
        ellipse(o.pos.x, o.pos.z, 20, 20);
        }
      }

      void mousePressed(){
      s.addObj(mouseX,mouseY);
      }


    }

Hello everybody,

i'm a system administrator in a school and i work with a teacher who wants to use processing with android mode. So, i'm trying to make it works but i have a problem when i try to run on device any example found in processing. This problem appears with all example i tried. I installed gradle on my windows10 and configured the path as i saw on the gradle website. Anybody can help me please ? Thanks (i paste the error in processing) :

Howdy,

I'm new to Processing and trying to build a very simple app to run on my android.

Getting the following error. Any suggestions would be greatly appreciated!!!!

Build folder: C:\Users\davef\AppData\Local\Temp\android1587529277536989285sketch
:app:preBuild UP-TO-DATE
:app:preDebugBuild
:app:compileDebugAidl
:app:compileDebugRenderscript FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:compileDebugRenderscript'.
> llvm-rs-cc is missing

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

If you can help me I think that I'm near to the solution

This is my MMORPG "WORLD OF ISTHANIA", an online rpg where we can level up our character and fight in some of the most crazy and fun adventures that you can not even imagine. https://dropbox.com/s/urwcj2e0uraois3/test2.avi?dl=0

After many years of studying java, processing, multithreading, network libs and other crazy things in the end it seems that I have not lost my mind and I still have some more brain to undertake this exciting experience.

While it is true that seen from the outside it seems easy, creating an MMO for me is still a feat of higher level since one thing is what it seems to be and another thing is what it really is and could only discover it by undertaking the programming a mmo of your own.

I have to say that it is being a very rewarding experience, because I am having to study new subjects and learn new techniques of access to concurrent data from several threads of execution, and this for me is really fascinating.

Good that I roll up ..

What I already have yujuu !!!!!! "Let me know that I'm super happy haha" ..

System of communication at low level based on the library for midi transmission "Open Sound Control" by network which I have to say that it works like a fast shot .. impressive. : D: D: D

I have the specific and customized network lib for my online game, the collision engine for mapGetPixel () that for this type of games seems very good and the truth is that in java it works like a quick shot too :)

I also have my Div fork called "gameLibZERO" in 3 versions, PC / LINUX / MAC accelerated by hardware, PC / LINUX / MAC by software, and ANDROID accelerated by hardware hehe. "In a very short time I plan to start the port to JavaScript" and so finally have the "engine" available for all platforms.

About the game itself, I already have the login system, the user account registration system 'inGame', the creation of characters ..

And what is already operative is the game and the dedicated server, customers can now create their account and login and can move around the world watching the content.

I have designed a system of dynamic lists of objects that I think that as a concept is also quite interesting, it is that the server sends a list of objects in real time to the client, discarding those that are not necessary for "distance to the player", from this way the server only sends the content that is close to the player and thus the bandwidth is not abused ..

The ingame character control system is based on encapsulating bits in an INT32 and sending it in streaming to the server.

I have also created a system that sends a message to the server every time warning that the player is alive and playing .. live and without playing or that the player has closed the APP. Also if this message does not arrive before a while the server disconnects "kick" to the player eliminating its instance of the server and updating its user account with its current inventory and position.

I leave you some very ugly screenshots of the game XD .. they are all place holder .. I hope not to cause some detachment of the retina.!

After doing this processing finally recognizes the imports:

These were the steps: 1. Download and unzip this: https://dl-ssl.google.com/android/repository/google_play_services_8298000_r28.zip

1. Open Google Play Services and copy 'libproject' folder

2. Go to your sdk folder and follow this path: android\sdk\extras\google\google_play_services

3. Paste libproject there

4. Go to libproject\google-play-services_lib\libs

5. Copy google-play-services.jar --- this is the jar that the sketch will use

6. Paste jar in CODE folder in sketch. That's it!

However I now when I try to run the code I get this error:

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':app:transformClassesWithDexForDebug'.

  com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexIndexOverflowException: method ID not in [0, 0xffff]: 65536

• Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

I also tried getting using r28 (not just copying libproject but replacing the whole google_play_services folder) and I still get this error.

So I had some Android sketches laying around which worked perfectly the last time I played them on my devices. Today I tried to play them again, and I keep getting this error! Just one time, the app actually played, but it wasn't different than all of my other attempts, it just worked 1 time! This is the error:

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':app:mergeDebugResources'.

  Error: java.io.FileNotFoundException: C:\Users\User\AppData\Local\Temp\android2968292313261529121sketch\app\build\intermediates\res\merged\debug\drawable-xhdpi-v4\abc_ic_star_black_48dp.png (The process cannot access the file because it is being used by another process)

So I just made this little sketch to try finish():

void setup()
{
  finish();
}

void draw(){}

And this is the error printed on the console:

    finish();
    ^^^^^^

I have updated to the lastest androidMode version, which is supposed to be compatible with Processing 3.1+.

The problem occurs every time I want to run a sketch that uses exit(). This is the error I am being shown:

Is there another function I must use in order to stop an app?

Interface Callable is a FunctionalInterface.
And therefore got 1 method only. In this case it's called call():
http://Docs.Oracle.com/javase/8/docs/api/java/util/concurrent/Callable.html

If there's any method called get() from it, most probably it is the object returned after invoking call().

And there's no way to confuse PApplet::get() method w/ the 1 from another type.
B/c the former doesn't need the access operator dot .: \m/

1. https://Processing.org/reference/dot.html
2. https://Processing.org/reference/get_.html

While for the latter, the dot . is obligatory. :>

This helped... Thanks...

Better to use a collection that's defined for passing information from one thread to the other rather than using synchronization here.

Import and swap out your ArrayList for eg. ConcurrentLinkedQueue Iterating should work correctly, although better to use poll() as it will remove the items as you go.

Hello!

I am hooking up my electric piano to processing using The MidiBus library. I'm basically playing around with visualising the notes played in different ways. This often includes adding some sort of object to an array or arraylist and then iterating through the list to call .update() which updates position, size etc for the object and draws it on the canvas.

However I often get the problem of "concurrent modification exception". I do not get this error when I run the code without the pian but just randomly call the note-pressed function. After some googling this leads me to believe that the error stems from me sometimes calling the notePressed() function, which creates a new object and add to the list, right in the middle of the update loop. Hence I am modifying the list whilst I am iterating over it.

So with that long introduction, here is my question:

Is there a way for me to tell processing "Call this function as soon as possible, but wait until next iteration of draw()"?

or alternativley : "Excecute this block of code without any interruption" ?

From my few qourses in Java i vaguely recall this issue beeing about synchronization, am I right?

Appreciate any help! :)

@GoToLoop, any advice on handling concurrent modification in this scenario?
