The logo was only applied when the Android project was first created, so an existing one kept Tauri's placeholder, and the round icon was a small tile inside a circle. scripts/release/android-icons.py draws the set from the icon source (adaptive logo in the safe zone over white; full-bleed white tile and disc for older launchers), and the post-init patch copies it on every build, local and CI.

"""Generate the Android launcher icons from the app's icon source.
|
|
|
|
Writes client/src-tauri/icons/android/ (committed). android-postinit-patch.sh copies
|
|
that set into the generated Android project on every build, so the launcher shows the
|
|
PS5Upload logo on every device:
|
|
|
|
- adaptive icon (Android 8+, what nearly every phone uses): the logo on a transparent
|
|
foreground layer, sized to sit inside the launcher's safe zone, over a white background;
|
|
- legacy square and round icons (older launchers): the logo on a full-bleed white tile/disc.
|
|
|
|
Run it again only when the logo changes: python3 scripts/release/android-icons.py
