How can i add admob to my app ?

Im working with a contributed library and i followed all the steps mentioned in the link

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

I'm getting a build error (attached image):

I have no clue what error it could be. Is it the version of android or something else?

Any help would be appriciated! -Thanks Goutham

This could go in the code in code sharing but is Android only so might be better here?

Basically I have been trying to find ways of making use of my physical SD card, as the default seems to always be the internal emulated SD (apparently for android historical reasons). This seems to be a common problem for us amateur developers if the number of questions about it at Stack Overflow is anything to go by! Anyhow... this is my approach which seems to work, so thought I'd share. Dependent on API level it gets the file path(s) for your sd cards and converts them to strings. The result is actually to a file area specific to your app (for private data) and here I simply text() these to the display in draw(), but it is now easy to extract the first part of the string(s) which is the top level path to the sd cards themselves. On my LG phone these are /storage/emulated/0 and storage/external_SD/ ... on other phones these will be different and on oldish phone will probably be /mnt/...

Anyway, hope it may be of some use to some of you.

Hi, as i said in the title of the thread, i need help to build a simple game in Processing. I made a menu, and, i would like to start the game in a new Activity. How can i do this with Processing (last version) ?

Sorry for my bad english. Thanks

Hello, My name is Varun Kumar. I am looking to propose an android app utilizing the current video app for a bigger project. I have been working with openGL, image and vision procsessing for a while now. It would be great if I could discuss about my proposal. You can either mail me to heysadboy@gmail.com or we can discuss here.

I can't figure how to make possible communication between a PC and Cell phone using network !? which library I have to use? not to program the cell phone but to exchange data between both. Thanks

Hi, a new beta release of the android mode is available for download. Two major changes:

• The Android Project Export option now uses Gradle
• Touch API is implemented, and is compatible with p5.js' touch API.

Give it a try, and report issues on GitHub. Thanks!

How can i use google-play score service?

PROCESSING GUIDES Hello.

-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.

I have made this request many times. But there was no answer.

What I want to do is :.

-. Step 1: Execute the application created by processing.

-. Step 2: Press the power button. The screen goes out.

-. Step 3: The screen turns on with an event occurrence.

In other words, how can you make the screen with the cellphone screen turned off?

Requirement 1: I want to turn on when the screen of the cell phone is off.

-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.

And I ask another one.

-. Step 1: Execute the application created by processing.

-. Step 2: Go to the desktop through the home button.

-. Step 3: A message appears after an event.

Requirement 2: Can I get a message from the home screen instead of the app's screen?

-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.

I want the sample code to be available. Thank you very much. Help.

I have tried to run my Processing code on my Android device. My device is successfully detected by Processing. But When I tried to run my code on my device, existed this error:

Error from inside the Android tools, check the console.

Additional Infos, see comments.

According to http://android.processing.org/install.html

In order to do this, first download the AndroidMode-xyz.zip file for the desired release or pre-release from the releases section in the GitHub repo of the Android Mode. Uncompress the zip file and then move the AndroidMode folder into the modes folder inside inside the sketchbook folder.

This is very confusing for me. I have downloaded the Android Mode 0258 (https://github.com/processing/processing-android/releases) and tried to copy the main folder (renamed to "AndroidMode") to "modes" folder in Processing folder and it doesn't work.

Or maybe I understood this instruction wrongly? What does it mean " inside the sketchbook folder"?

Will processing be able to adapt codes for Bluetooth and Wi-Fi Connectivity in creation of GUIs? Which can be used in communication or controlling of arduino projects?

Hello I am new to processing. I am having trouble with processing in the android mode, using "PImage" and "loadImage" when I choose "orientation(LANDSCAPE);". My simplyfied Code:

     import java.util.*;  //To use ArrayList
    ArrayList<PImage> bilder_a;

    void setup() {
      fullScreen();
      orientation(LANDSCAPE);
      background(0);

      //Load Pictures:
      bilder_a=new ArrayList<PImage>();
      int pic_anzahl=9;
      String pic_name;
      for (int i=0; i<=pic_anzahl; i++)
      {
        pic_name="pic_a"+i+".JPG";
        bilder_a.add(loadImage(pic_name));
      }
    }

I use the newest stable Version of processing, 3.3 and the newest and stable Version of SDK for Windwos 10, 64Bit. I already reinstalled the two, to see whether there is a software failure. But it does not solve anything. In my Sketch folder, I have the "data" folder with all the pictures... I am using an Oukitel K10000. My code works fine, when I run it in Java-Mode, but fails in Android-Mode:

-post-build:

debug: FATAL EXCEPTION: Animation Thread Process: processing.test.trouble, PID: 11536 java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.res.AssetManager android.app.Activity.getAssets()' on a null object reference at processing.core.PApplet.createInputRaw(Unknown Source) at processing.core.PApplet.createInput(Unknown Source) at processing.core.PApplet.loadImage(Unknown Source) at processing.test.trouble.trouble.setup(trouble.java:36) at processing.core.PApplet.handleDraw(Unknown Source) at processing.core.PGraphicsAndroid2D.requestDraw(Unknown Source) at processing.core.PApplet.run(Unknown Source) at java.lang.Thread.run(Thread.java:818) [The application does not crash, when I start it with my smartphone turned to the right landscape mode, but that is obviously not a solution...]

The strange thing is..., the Code works fully-fine even in Android-Mode, when I delete the line "orientation(LANDSCAPE);" or when i delete the line "bilder_a.add(loadImage(pic_name));". I know, the LANDSCAPE and PImage-stuff had been discussed like a thousand times.. but I never found a discussion, that focuses, the combination of LANDSCAPE and PImage, which obviously makes me trouble.

I hope you can help me, thanks a lot by now!

Hi, I am working on uploading my app the the Play store. I want to restrict screen sizes that my app will display to by adding code to the manifest file. I have tried editing the AndroidManifest.xml file in the sketch folder. However, it appears that the file is automatically generated, because after I create the signed .apk file my changes to the manifest file are no longer visible. How can I edit the manifest file so that my .apk will take the changes? Any suggestions would be appreciated.

APDE application after export apk for Android is not installed. In APDE working. Prompt please the reason.

Hi everyone,

Thanks for taking the time to read this. I'm using Android Studio to package my processing sketches as outlined here.

I have a basic test sketch working fine which simply draws ellipses on screen. However, I'm having issues loading images and other media files, usually they would go into the data folder (I'm more used to p5.js in which case I put them into an assets folder and load them using relative URLs).

Where do I need to put images/mp3s within my android project so that I can load them using PImage and loadImage with processing?

If anyone can help I would greatly appreciate it.

Thanks,

Matt

I 've coded some live wallappers with processing. However the parameters are fixed (for example the size of a ball); How can a normal app set them through user input?
