The useful starting point
A downloadable source bundle and a signed Android package are different outputs.
Start with the right information
Make the published website work well on a phone first. Check navigation, touch controls and the behavior when the network is unavailable.
Put it into practice
Choose the available Android export path in the project. A connected build needs the configured worker and signing setup; review its status before downloading.
Check before you share
Test the produced package on an appropriate device before distribution. Store signing credentials with the operator, outside website source and public files.
