Echo Music Adds Support for Google Cast and DLNA

[iad1tya]

Echo Music now supports Google Cast and DLNA, allowing you to stream audio to compatible speakers, TVs, and other devices on your home network. To enable these features, the app must request Nearby Devices and Location permissions. These permissions are required by Android so the app can discover cast-capable devices on your Wi-Fi network.

Why These Permissions Are Needed

Nearby Devices Permission

This permission allows the app to scan for devices around you that communicate over Wi-Fi, Bluetooth, or your local network. Echo Music uses it to detect:

• Google Cast speakers
• Smart TVs with casting support
• DLNA-enabled devices

Location Permission (Required by Android)

Android treats Wi-Fi–based device discovery as a location-related operation. Even though Echo Music does not use or access your physical location, the operating system requires Location permission because:

• The presence and names of network devices can indirectly reveal your physical environment.
• Google Cast scanning relies on Wi-Fi signals, which Android's security model groups under location-sensitive data.

Because of these system-level rules, any app that scans for Cast or DLNA devices must request Location permission, regardless of whether it uses location data.

How Echo Music Uses These Permissions

Echo Music does not collect, store, or upload any data from these permissions. They are only used when:

• You open the Cast or DLNA device selector, or
• You attempt to connect to a device on your network.

If you never use Cast or DLNA, these permissions remain unused.

If You Deny Location Permission

Echo Music will continue to function normally for:

• Local playback
• Library browsing
• Playlists
• All offline features

The only limitation is that Google Cast and DLNA will not be available, since the app cannot discover devices on your network without the required permissions.
