blank white screen on android 6.0

[jango-fx]

i'm trying to get a simple test sketch to run on Marshmallow. But all i get is a blank white screen. The same goes for any other example sketch.

i'm on

• OS X 10.11.4
• javac 1.8.0_92
• Android 6.0
• Motorola XT1068
• Processing 3.0.2
• Android SDK: API 6.0 (23)

i don't get any errors. except for those warnings. and i don't seem to get any feedback from println(); either.

The import processing.data is never used
The import processing.event is never used
The import processing.opengl is never used
The import java.util.HashMap is never used
The import java.util.ArrayList is never used
The import java.io.File is never used
The import java.io.BufferedReader is never used
The import java.io.PrintWriter is never used
The import java.io.InputStream is never used
The import java.io.OutputStream is never used
The import java.io.IOException is never used

my code is really just a super basic test sketch:

void setup()
{
  background(0, 0, 255);
  rectMode(CENTER);
}

void draw()
{
  background(0, 255, 0);
  fill(255, 0, 0);
  rect(width/2, height/2, 50, 50, 50);
  println("i'm alive");
}

i'm out of ideas...

Having the same issue since the latest update. Looks like draw() is not being called.

Thanks for the info, will look into it.

Do you have the same problem if you use API 21 or 22?

[sesmusician]

Yes, same problem using API 21, 22 ,and i also used API 15 just in case.

I just had this problem, and it's "fixed" by calling size() in your setup function. Discovered this by accident while trying example code.

"fixed"" because this results in a non-fullscreen sketch window centered on the device; obviously not optimal but at least you can do stuff with it

[jango-fx]

well, good enough for me at the moment. if it's called in settings(), it works fullscreen, too.

void settings()
{
    size(displayWidth, displayHeight);
}

Thanks for bringing this up. There was an actual bug: on the desktop, Processing sets a default width/height of 100x100, however this was not being done in the android mode. Now it is.
