I found no clear documentation for building a version of Processing (versions 4.xx) which works with Android correctly. It seems that different Processing versions need different Android mode versions and different SDK files.  
Any method I tried to use did not work and I could not run existing proven sketches with any one of them.  
Can anybody recommend a process to build a Processing for Android package which runs with no problem?

Thanks  
Mike

Hi! I’m sorry that things are broken. Can you help me understand how you’re doing it and share some of the error output? Then I can see about how to get it fixed.

Thank you Moon.  
I am giving a description of one of my attempts:  
I deleted the previous version of processing and Android mode  
I installed Processing version 4.5.3, and checked it by running a few sketches. They run correctly.  
Then I installed Android mode through the IDE. The IDE provides only AndroidMode version 4.6.1.  
I selected to use the automatic option for the SDK.  
Any sketch that I try to run fails. I get tens of error lines such as the error log below. Other attempts with other Processing versions are not providing better results.  
Thank you in advance for any idea.

Same for me.

I installed Processing version 4.5.2, Android Mode version 4.6.1 automatically, but unfortunatly it doesn’t work.

When I launch the “Run on device” command I get errors such as:

A newer Android Gradle plugin is recommended. The installed Android Gradle Plugin (7.1.0) was tested up to compileSdk = 32

Sdk version android-33 is expected where android-33-ext5 is installed.

Can anybody explain the way to proceed?

Thanks a lot.

Patrick

I am surprised that nobody from the Processing forum supervising team has expressed any interest in this issue which has been reported by quite a number of users.

> Hello @MPROCD, I had issues with a fresh install of Android mode and the latest SDK. I installed Processing 4.5.3 and used an older SDK and it worked! Older SDK had this: Latest SDK download had this: I had to modify the preferences.txt manually to add the SDK location: There were issues trying to add it with the new preferences UI (User Interface) so I abandoned that approach. slight_smile
