Hello everyone, I did not understand very well and would be grateful if someone could explain. If I create an app for a 5-inch screen and use that program on a 4-inch screen, does the program reset the new resolution automatically or for each screen do I have to make a different app? Thanks in advance.

Can anyone please help me out with solving this errors!! I have codded this app in processing. Then i applied layouts to app in Android Studio.

This the Error message:

Error:java.util.concurrent.ExecutionException: com.android.ide.common.process.ProcessException:

Error:Execution failed for task ':app:mergeDebugResources'.

Error: java.util.concurrent.ExecutionException: com.android.ide.common.process.ProcessException:

Hi.

My goal is to build an Android App that login itself at my university members area and grabs personal infos.

Now, i know that probably the website uses Shibboleth auth system. Unfortunately, i don't know how to start....

How can i do it using Java ?

Is it possible to let processing to communicate with Android WallpaperService.Engine?

(or "interact / integrate" sorry, I just don't know the right word. English ist not my mother tongue)

Thanks

Hey, After fiddling around for a while I've created a live wallpaper in the new beta mode, and I'm quite pleased with the result. However, if I enable rotation in my launcher (Google Now) and switch between horizontal en vertical orientation a few times, the animated elements are not alligned correctly anymore, the background however is still visible. If it helps, I am testing on a S7 Edge.

Thanks in advance!

Hi, here is a code to generate sinewave in android mode

import android.media.*;
import android.content.res.*;

PlaySound sineWave = new PlaySound();
boolean on=false;

void setup()
{
  size(displayWidth, displayHeight);
  sineWave.genTone(340);   //frenquency
}

void draw() {
  if (mousePressed) {
    delay(100);
    if (on) {
      on=false;
      sineWave.playSound(false);
      print("off");
    }
    else {
      on=true;
      sineWave.playSound(true);
      print("on");
    }
  }
}

And the Class Object :

public class PlaySound {
  private final int sampleRate = 8000;
  private final int numSamples = sampleRate;
  private final double samples[] = new double[numSamples];
  private final byte generatedSnd[] = new byte[2*(numSamples)];

  final AudioTrack audioTrack = new AudioTrack(AudioManager.STREAM_MUSIC,
  sampleRate, AudioFormat.CHANNEL_CONFIGURATION_MONO,
  AudioFormat.ENCODING_PCM_16BIT, numSamples,
  AudioTrack.MODE_STATIC);

  void genTone(double freqOfTone) {
    // fill out the array

    for (int i = 0; i < numSamples; ++i) {
      samples[i] = Math.sin(2 * Math.PI * i / (sampleRate/freqOfTone));
    }
    // convert to 16 bit pcm sound array
    // assumes the sample buffer is normalised.
    int idx = 0;
    for (double dVal : samples) {
      // scale to maximum amplitude
      short val = (short) ((dVal * 32767));
      // in 16 bit wav PCM, first byte is the low order byte
      generatedSnd[idx++] = (byte) (val & 0x00ff);
      generatedSnd[idx++] = (byte) ((val & 0xff00) >>> 8);
    }
    audioTrack.write(generatedSnd, 0, numSamples*2);
    audioTrack.setLoopPoints(0, numSamples/2, -1);
  }

  void playSound(boolean on) {
    if (on) {

      audioTrack.play();
    }
    else {
      audioTrack.pause();
    }
  }
}

Hi all,

When trying out android mode in processing I get the following error:

C:\Users\Matt\AppData\Local\Temp\android3005389885981532069sketch\build.xml:81: Cannot find D:\Tools\Android\sdk\tools\ant\build.xml imported from C:\Users\Matt\AppData\Local\Temp\android3005389885981532069sketch\build.xml

I have the SDK installed to d:\Tools\Android\SDK however within the tools folder there is no ant folder. I have no idea what ant is or why ti would be missing? I have Android Studio installed on the same machine and this is able to build apps without any issue, can anyone help?

Thanks,

Matt

Hi everyone, I found an old project of mine, that I'd like to get some criticism on. I can clearly see that the code is bad, but would like to know/see what you would have done instead of what I did. So please #RoastMyCode:

Hello, I am having an issue regarding app permissions. My app requires one permission which is "write_external_storage." When I build it and run it locally on my phone it works as expected and I can see in the android application manager that it is requesting one permission. However, (and excuse me if this is the wrong place to ask this question) I have uploaded it to the Google Play store and when I download it from there are run it on my phone the app does not ask for any permissions. As a result I am not able to use the write_external_storage function that I need.

I have decompiled the .apk and I can see that in the manifest file it says:

also, it looks like it is targeting level 21 if that is relevant to the discussion:

android:targetSdkVersion="21" />

Thanks in advance!

Hello Processing community,

when I'm trying to run this code in Android mode, i get a error message:

PVector Vec;
void setup(){
  Vec = new PVector(0, 0);
}

void draw(){
  Vec.add(1, 1);
}

In the Java mode it works just fine. Is is a bug or do i have to redownload Processing? I have already redownloaded the Android mode. I know that i could just use Vec.x += 1; Vec.y += 1;, but I thought I would tell you guys, because the problem isn't listed here: android.processing.org/reference/gone.html

Sorry for my bad English and thanks for the answers

Hi, I'd like to write an app that involves continuously scanning the screen of an Android device into a PImage variable. How do I do this in real time?

Hey,

does someone have experiences with connecting an Arduino Pro Micro or Leonardo to an Android phone over USB ?

Found this https://github.com/mik3y/usb-serial-for-android https://groups.google.com/forum/#!topic/usb-serial-for-android/8-fLuUn2Yns

and this https://github.com/inventit/processing-android-serial.

But I have no idea how I would use the AndroidLib in Processing(AndroidMode) and the second method simply doesnt work for me.

thanks, cheers !

Hey, I'm having a problem where my standard canvas size (without size() method) is only 100x100, and I also can't change it with size(). On a new sketch with size() and background() set it works, but not with my app. I also tried to comment out basically everything. Didn't have this problem before. I think it started when I updated processing and android-mode. Can someone help? cheers

Hi! I want to know that can I override Android methods like onPause(), onResume() in Processing? I also want to override "back" key. Because by default if I press back key it closes the sketch. I dont want that to happend. Thanks in advance :)

Hi all!

I'm happily using Processing from the Android IDE, allowing me to add certain critical functionality through Android Java directly. For the project I'm now working on, I want to overlay all kinds of nice Processing sketches, in a "virtual reality" way, over a camera view. Because displaying the camera view and doing the required detection is a bit heavy, I'll be doing this with OpenCV instead of Processing. My idea was to then simply overlay the Processing sketch fragment over the OpenCV fragment, thus allowing the cool 3D stuff to be easily programmed in Processing, while the more intensive camera stuff is done with OpenCV.

However, although I've managed to make simple Android fragments semi-transparent, I can't seem to be able to make the Processing sketch fragment semi-transparent. Maybe this is because it's neccessary to go all the way down to the SurfaceView involved and make it semi-transparent or something?

I'd be very much obliged if someone could help me out :)

The code is generally as follows:

The main layout file:

<RelativeLayout android:layout_width="fill_parent" android:layout_height="fill_parent" ... > <FrameLayout android:id="@+id/bg_frame" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#cc0000" ... > <FrameLayout android:id="@+id/fg_frame" android:layout_width="fill_parent" android:layout_height="fill_parent" ... > </RelativeLayout>

The Processing sketch:

public class MySketch extends PApplet { ... public void draw() { background(color(255, 50)); // semi-transparent ... } ... }

The activity:

public class MainActivity extends Activity { ... protected void onCreate(Bundle savedInstanceState) { ... getFragmentManager().beginTransaction() .add(R.id.fg_frame, new MySketch()) .commit(); ... } ... }

I have tried (as you can see above) using Processing's background color background(color(255, 50)).

Also, I've tried setting android:background="@android:color/transparent" as well as android:alpha="0.5f" in the fb_frame frame layout.

Hi,

I have written a simple Android app as part of an effort to expand the services of e-NABLE to include help for the blind and visually impaired. The app emits a tone that varies in frequency according to the brightness of the pixel touched. The technique is nothing new and has limited utility but it's a good start in the right direction. You can find it on GitHub by following this link:

https://github.com/LesHall/blind-sight

At this time it works on the front cam image only. If we could take a screenshot of the entire Android display and determine the coordinates of the operator's finger on that display, then we could "e-NABLE" the operation of cell phones for blind and visually impaired people. I'm not sure if this is out there, but if it isn't then this could be of great benefit for those who need it.

Further developments may include time-spectral mapping of FFT's of the fingerprint or image or some other encoding that could be learned by the operator to sense the phone's screen or part of it. Also if such a thing can be done on a cell phone, then it is a simple matter to put the back cam on and point it around like a window on the world. You can imagine how powerful that could be for many people.

Thanks in advance for whatever help you can offer.

Hello Processing community, everytime I launch a sketch on my smartphone the sketch immediately stops and the message "[sketch name] stopped" pops up (on my smartphone, Samsung Galaxy S6, Android 6.0.1). A few days ago I didn't have this problem. I already tried: - restarting both my smartphone and desktop pc - reinstalling both Processing and the Android Mode (and the Android SDK) - using another account on my desktop pc It doesn't matter what's inside the sketch, even an empty program or an Example by Processing don't work. Everything works fine on the Java Mode. Please help me

How can i use scoreboard of Google play ? Can anyone give example about it ?

Hi, I'm very new to processing and I'm trying to get a sketch to run on the emulator or device for the first time. I've spent four days scrolling through forums but nothing seems to have fixed the issue. The emulator will load up completely but when I run my sketch on it, it says "could not create a virtual device for the emulator". If I try to run it on my device it say's that it lost connection to the device. The android API is set to 6.0(23) on the target SKD. The SKD manager is downloaded and have the relevant APIs and tools downloaded. My AVD is set as Processing-0217 and will load up fine but won't load a sketch. In order to check that this wasn't my novice coding affecting things, I'm trying to run a simple black background with a white box so I don't think this is an error with the coding. No error message comes up but I do get 14 warnings that i've pasted below. Any ideas on how to fix this?

Are OSCP5 messatges only compatible with OSCP5 messatges ? Is there any libary which allow me to make a tcp client as processing.net.* but in andorid mode? I just want a recieve data send by a arduino launchpad. Thank you
