How to change "PythonActivity.java" to load mp4 file on presplash

[Felipe738743872]

Versions

• Python: 3.8.7
• OS: mac
• Kivy: 2.0.0
• Cython: 0.29.21
• OpenJDK: 8

Description

Estou tentando adaptar o "PythonActivity.java" para carregar videos mp4 ao invés de imagens estáticas no presplash, alguém sabe como fazer isso? Ingenuamente troquei todos "ImageView" para "VideoView" e obviamente não funcionou rsrs, não sei se isso é muito trabalhoso de fazer ou é fácil, então desculpem por qualquer coisa :(

• while you can't use videos, you can currently use lottie animations, which are much lighter than a video, for presplash, if you use the develop version of p4a.
