I'm trying to make sure Blepdroid (https://github.com/joshuajnoble/blepdroid) works well before I tell more people about it and I'm able to use it from Eclipse Luna (aka 4.4.2) without issues, e.g. I write a Processing app there and link it to the Processing Android library. It does not seem to work from the Processing IDE though, which is puzzling. Both places I'm using Android SDK 6.0 (v23) and the phone I'm using is a Nexus 6P running Android 6.0.1. My machine is a OSX 10.11, running Processing 3.2.1, Java 1.8._101 and with the newest released version of the Android Mode installed.

One more curiosity that may (or may not) be a clue: I can't println() from any of my Android sketches suddenly. I see them in Eclipse, but not the Processing IDE.

Any tips of what might be going on would be seriously appreciated, I'm not super savvy with what might be going on in the Android/Java internals

I was wondering after I code my program what the steps are to get an app published on the google play store. Keyword: steps

Hi! I need some help, please! I'm making an Android app where I want the user to select an image from the gallery to load into the app, I've seen the method selectInput() but it's only working in Java mode for me, not in Android. When trying it in Android mode it gives me this error: The method selectInput(String, String) is undefined for the type "nameOfTheSketch" And says that the Compile Failed.

Good day to everyone, I'm stuck in a problem since two days, googling everywhere and making only little steps forword. Now i decided to register me in this forum to ask for help :) . After some efforts i'm now able to run all kind of sketchs on my device "galaxy s2 (API 11)", via android mode, even displaying images by -> add file... (that creates a data folder) and all images are well understood by the device app. (processing 3.0.2, windows 10, 64 bit) When i was trying to put some audio, the first times i get crash from the app launched on the device, after i understood that the problem was that the file was not found by the apk app. So i found https://forum.processing.org/two/discussion/12819/how-do-i-get-sound-to-play-on-the-phone#latest

where @Akenaton (thanks you!) finally wrote a code that works. The problem now is that if i "run on device" the simple code, it works, but if i start inserting images in the data folder, at some number beethween 20 and 24 , during debug "j'arrive pas à préparer" it's shown (so, you are French :) i'm italian) .

What the hell?? Why if I increase the number of files ( size 3 or 4 MB, so no problem with total size) the try{}catch{} statement can't find the myfile.mp3???

I've done those tests without adding any additional line of code to the code that works (powered by Akenaton).

thanks for answering and for the attention ps: i also tried with my full code , and all images are well displayed and the sketch runs, without sounds,so the problem is just for .mp3 audio files

Processing 3.2.1 installed. Android SDK installed, working. AVD API 23 Created, running on emulator. Windows 7. 64bits. When I run a sketch in emulator Processing brings me this message:

My device Galaxy Tab 2 - 10.1 just can't be detected.

Some idea to solve it? Thanks.

Hi!

I am able to run a sketch on my tablet while plugged into my computer, but how do I run a sketch on an Android device without USB connection. Am I missing something?

Thanks!

Hello, when i save the screen image, the result is a file with the correct name and the correct directory on my device, but the file is empy. This is my code:

void setup() { size(1200, 700); strokeWeight(4); background(255); textSize(30); rect(0,0,1200,700); rect(10,650,180,40); rect(1000,650,180,40); fill(0); text("CLEAR",40,680); text("FATTO",1040,680); }

void draw() { if (mouseY<640){ line(mouseX, mouseY, pmouseX, pmouseY);} if ((mouseX>10)&(mouseX<200)&(mouseY>650)&(mouseY<700)){ fill(255); noStroke(); rect(2,2,1195,645);stroke(0);} if ((mouseX>1000)&(mouseX<1200)&(mouseY>650)&(mouseY<700)){ fill(255); noStroke(); rect(2,645,1195,695); delay(100); saveFrame("/sdcard/infoconterm/firma.png"); delay(200); exit(); }}

I activated WR_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE.

Hey! I was able to get this code to work on two computers, but it's not working at all when I try to run the sketch independent of the browser on my tablet. I'm wondering if this has something to do with the port number or android mode?

Here is the code on my tablet:

    import oscP5.*;
    import netP5.*;


    Buttons button1;
    Buttons button2;

    OscP5 oscP5;
    NetAddress myRemoteLocation;

    void setup() {
      size(600,800);
      frameRate(25);
      /* start oscP5, listening for incoming messages at port 12000 */
      oscP5 = new OscP5(this,12000);



      myRemoteLocation = new NetAddress("192.168.1.179",12000);


      button1 = new Buttons();
      button1.x = 100;
      button1.y = 100;
      button1.w = 100;
      button1.h = 100;

      button2 = new Buttons();
      button2.x = 250;
      button2.y = 100;
      button2.w = 100;
      button2.h = 100;

    }


    void draw() {
      background(0);
      rectMode(CENTER);

      fill(squareColor, 0, 0);

     button1.display("hello");

     button2.display("fractured");

    }

    void mousePressed() {
       button1.clicked("hello");
       button2.clicked("testing");

    }

    void clicked(String wordMessage){
      float d = dist(x, y, mouseX, mouseY);
      if (d < 50) {
       boxBackground = 255;
       OscMessage myMessage = new OscMessage(wordMessage);
       oscP5.send(myMessage, myRemoteLocation);
       println(myMessage);
      }

Here is the code on my computer:

    import oscP5.*;
    import netP5.*;

    int circleColor = 200;

    OscP5 oscP5;
    NetAddress myRemoteLocation;

    void setup() {
      size(400,400);
      frameRate(25);
      oscP5 = new OscP5(this,12000);

      myRemoteLocation = new NetAddress("192.168.1.128",12000);
    }


    void draw() {
      background(0);
      rectMode(CENTER);

      fill(circleColor, 0, 0);
      ellipse(width/2, height/2, 100, 100);



    }


    void oscEvent(OscMessage theOscMessage) {

      print("### received an osc message.");
      //print(" addrpattern: "+theOscMessage.addrPattern());
      println(" typetag: "+theOscMessage.typetag());

      if(theOscMessage.checkAddrPattern("poopin")==true) {
        println("it worked!");

      } else if (theOscMessage.checkAddrPattern("hello")==true) {
       println("yay, it worked!");
      }

    }

I made an app and exported it using APDE however when I go to upload it to the play store I get this error:

"Upload failed Your APK cannot be analysed using aapt. Error output: Failed to run aapt dump badging: ERROR getting 'android:name' attribute: "

Does anyone know how to fix this?

Thanks

I have a fresh install of processing and an updated java. I let processing load the android mode and then it asked to downlload the android emulator. this is a mid 2012 macbook pro running osx yosemite and latest download of processing 3.

when I go to the AVM manger and tell it to start manually I get the following output text:

I have created Android app as tcp client and my pc is acting as tcp server(processing in java mode).I am using oscP5 library.

When i try to run android app on mobile (with Wifi or mobile data 'on'), black screen will appear. After few minutes, app got loaded with error (TcpClient IOException while trying to create a new socket processing).

But when i load the android app without internet connection, it works normally. But, of course, it's of no use.

Also, when i run both client and server in Java mode, everything works fine.

I have tried these things:

• PC firewall off.
• App has internet permission. I also checked Android manifest.
• Changes the ip and port.
• Checked the 'security type' of internet connection. Its same on mobile and PC.

Kindly help.

I want to scan QRcodes using the Ketai Android support library, As we all know it has KetaiCamera which utilizes your mobile phones camera and actually reads the images out of it. I want to integrate Zebra Crossing to scan qrcodes for image processing projects.

I recently found this code in GitHub and tried it on my system: https://gist.github.com/darkwave/43352f775e6f767a11cb

After running this sketch I had problems with: ->PlanarYUVLuminanceSource ->BinaryBitmap bitmap

After doing some research I found that there is a java file that you can add to your sketch inside the Zxing Library C:\Users######\Documents\Processing\libraries\zxing\core\src\main\java\com\google\zxing "PlanarYUVLuminanceSource.java"

I tried adding that to my sketch in hopes of utilizing this java code to this old sketch i found on github but it has given me another error and now i'm stuck.

java.io.IOException: The filename, directory name, or volume label syntax is incorrect at java.io.WinNTFileSystem.createFileExclusively(Native Method) at java.io.File.createTempFile(File.java:2024) at processing.app.Util.saveFile(Util.java:172) at processing.mode.java.JavaBuild.preprocess(JavaBuild.java:532) at processing.mode.android.AndroidBuild.createProject(AndroidBuild.java:160) at processing.mode.android.AndroidBuild.build(AndroidBuild.java:94) at processing.mode.android.AndroidMode.handleRunDevice(AndroidMode.java:295) at processing.mode.android.AndroidEditor$16.run(AndroidEditor.java:553) processing.app.SketchException: Problem moving PlanarYUVLuminanceSource.java to the build folder at processing.mode.java.JavaBuild.preprocess(JavaBuild.java:538) at processing.mode.android.AndroidBuild.createProject(AndroidBuild.java:160) at processing.mode.android.AndroidBuild.build(AndroidBuild.java:94) at processing.mode.android.AndroidMode.handleRunDevice(AndroidMode.java:295) at processing.mode.android.AndroidEditor$16.run(AndroidEditor.java:553)

Anyway, Any ideas?

info shows in the image solved,It's version problem,If you using ""Add Mode" in P3.1or3.2 IDE,It didn't provide right version,You shoulde manualy find relate version from github,I answered myself below.But there no button to choose my own answer (- _ -!)

Could you please show me the right way to close TCP client?

I'm trying to create APKs for use on older phones and older versions of android. I have tried installing the older Target SDKs to Processing 3, but I get the following build Errors.

BUILD FAILED C:\Users\user\AppData\Local\Temp\android1768334546505923503sketch\build.xml:15: The following error occurred while executing this line: C:\Users\user\AppData\Local\Temp\android1768334546505923503sketch\build.xml:28: Compile failed; see the compiler error output for details.

Is there a good way to make APKs compatible with old phones? Thanks.
