Is there a way to play an audio while the Kivy application is loading while running on Android devices? That is play an audio while the presplash image, defined in the buildozer.spec file, is displayed on the screen.
There is no prebuilt way to do it. It would be possible to achieve by editing the Java code managing app loading, in the same place that the presplash image is set up.
