I may have figured something out.  
After exporting the project to android studio and doing the usual fixes required following that, I got this error:  
`Cannot fit requested classes in a single dex file (# methods: 68587 > 65536)`  
and somewhere else in the errors this:  
`The number of method references in a .dex file cannot exceed 64K.`

the solution to this normally according to [this stackoverflow](https://stackoverflow.com/questions/36785014/the-number-of-method-references-in-a-dex-file-cannot-exceed-64k-api-17) is to add ` multiDexEnabled true` in `build.gradle`

This worked but I want to continue working in processing for now.  
I will mark this as a solution and start a new topic for that.
