Processing sketch won't open on android device. #729

powerm9 · 2023-02-28T10:33:34Z

I can't run any sketch on my device, even the tutorial code. The code builds and I can see the sketch on my homepage but it crashes on startup. This is my first time using Processing for Android. My phone is a Xiaomi Redmi Mi 9t.

Tutorial code:

void setup() {
  fullScreen();
  noStroke();
  fill(0);
}

void draw() {
  background(204);
  if (mousePressed) {
    if (mouseX < width/2) {
      rect(0, 0, width/2, height); // Left
    } else {
      rect(width/2, 0, width/2, height); // Right
    }
  }
}

Here is the error code:

Edit: Just tried in my friend's phone and it worked. I don't know why my phone's not working though.

That's odd. What version of Processing and the Android mode are you using?

powerm9 · 2023-04-02T10:47:56Z

Android Studio 2022.1.1
Processing 4

I actually got a new phone recently, and it all works on that.

I have two Android tablets connected to my system: old Galaxy S2, new Galaxy A8. The following code runs ok on the S2, but fails on the A8 with the same error message as that shown above. Processing version is 4.2.

void setup() {
  fullScreen();
  background(209);
}

void draw() {  
}

Error message for A8:

ajavamind · 2023-04-17T17:55:05Z

I ran into a similar problem using Android Mode 4.5 (version 410) recently.
I built a sketch for a tablet with Android API 15 (4.0.4) and the verify error appeared.
The minimum target SDK is API 17 in Android Mode 410.
I found it could not verify any class using the AppComponent.WATCHFACE.
I built my own Android Mode library commenting out all AppComponent.WATCHFACE and references to watchface from PSurfaceNone.java, PSurfaceAndroid2D.java, PSurfaceGLES.java

I would like to continue to use Processing Android with old Android devices (10+ years).
Tried to attached the modified AndrodeMode.zip file I built, but it is too big.

I made a repository with zip file at https://github.com/ajavamind/processing-android-410-api-15

@ajavamind Thank you very much for your contribution; it appears that you solved the problem. I downloaded your zip file and placed it in the 'modes' folder of my Documents/Processing folder (macOS). I was then able to run a simple sketch on the new Galaxy A8 tablet without error using your version of AndroidMode.

vsquared · 2023-04-20T19:06:20Z

Do you have any suggestions about how to solve this problem: #736 ?

I have the same problem. Here is my configuration:

Device: Samsung Galaxy Note 4 (Android 11 -- LineageOS)
Processing: 4.2.1 (installed from AUR in ArchLinux)
SDK Platform tools version: 34.0.3
Android Mode for Processing: 4.5.1

I will try with other devices and versions of Android.

Edit: it works correctly in a Huawei P20 Lite (ANE-LX1) with Android 9.1 (stock)

bagnacauda · 2023-07-11T13:14:25Z

Same here, with a Poco X3 Pro and LineageOS (could that be the reason?)
