Hi kf. I am having the same problem really. I haven’t been able to run it even a single time yet.

In my case, I can see folders …AppData\Local\Temp\android1078933721650358847sketch\app\build\generated\source\r\debug

So basically, ‘debug’ folder is empty.

I am using Windows 7 with latest version of processing 3.5.2

I read somewhere (I am not able to recollect now where) that environment variables could play a role here. Do you think so too? If yes, what settings shall I do in environment variable? I am not a full time coder and that’s why avoiding use of Android Studio.

My code is very simple since I want to test a successful build first. and it works in Java mode:

Following is the code:

int i=0;

void setup()  
{

size(400,400);  
background(255);  
}

void draw()  
{  
background(255);  
float i = random(400);  
ellipse(width/2,height/2,i,i);  
delay(5);

}

Your help will be appreciated. 🙂
