Hello,
You may want to change category to Processing for Android.
Most of the basic sketches I write work on my Android.
Which one are you using?
The tutorials on the Processing website may be a good start:
https://processing.org/tutorials/
This one discusses shapes and lines:
https://processing.org/tutorials/drawing/
There are other tutorials you may want to visit first.
Looking through all the resources can be very helpful!
I encourage you to look up the reference for each method\function in your code:
- Variable Scope / Examples / Processing.org
- setup()
- draw()
- background() This needs to be understood.
- random()
- line()
- And the related references at the bottom of each page.
The Coding Train has tutorials:
Happy Coding:

We were all beginners and I feel like one with each new coding challenge.
