@Rogo ===
It depends of your needs (there are a lot of ways for doing that); yet, as for beginning see here: [https://discourse.processing.org/t/need-help-with-play-video/20260/3](https://discourse.processing.org/t/need-help-with-play-video/20260/3)

I have only been using processing for a few days now, can you show me how to do this with the video so I can learn best if someone fools me and if I don’t understand it I can always ask

Did you change the (video\_title = “vid.mp4”; ) with your video name located in the data folder?

If this is homework you are not supposed to replicate someones other code. It’s posted there only as a guide line. May I ask if the teacher mentioned Processing for Android to do this task?
The error means that the file was not found.

You didn’t answer my question!
Further more if you use this code on APDE, you have to run it in “app” mode.

It’s because he tested it in “Preview mode” instead of “App mode” (A very fast compiling mode, codeanticode is planning to implement it on P4A PC as well)
I can see it on the image he posted.
