First, understand the limitation
Most HomePod listening flows expect an iPhone, iPad, Mac or Apple TV. Android cannot simply pair to a HomePod like a normal Bluetooth speaker because HomePod does not expose a standard Bluetooth audio input for everyday playback.
That means the useful path is AirPlay over Wi-Fi, not Bluetooth pairing.
Put both devices on the same Wi-Fi
AirPlay discovery happens on the local network. Your Android phone and HomePod need to be connected to the same Wi-Fi network, and the router must allow devices to discover each other.
If your network has guest isolation enabled, your phone may not see the speaker even though both are online.
Use an Android AirPlay sender
Bridge Audio is built for this exact job. It discovers compatible AirPlay speakers on your network, captures Android playback audio with the system capture permission, then streams that audio to the selected speaker.
Because it captures phone audio, it is not limited to one music app. Spotify, Apple Music for Android, YouTube, podcasts and browser audio can all use the same route.
Expect local-network behavior
This is not a cloud speaker handoff. Keep the phone and HomePod on the same Wi-Fi, leave Bridge Audio running while you listen, and use the foreground notification or widget for quick controls.
If audio stops when your phone locks, check battery restrictions and make sure Android is allowed to keep the foreground streaming service active.
When an Apple TV is involved
Some homes have a HomePod paired with Apple TV. In that setup you may see both the Apple TV and the HomePod-style speaker target. Pick the speaker target you actually want, and check the app label so you know whether you are streaming to HomePod directly or routing through Apple TV.
Bridge Audio shows detected speaker capability details so Android users are not left guessing which endpoint they tapped.
