Directly transmitting content from an Android device to a Roku device typically requires both devices to be connected to the same Wi-Fi network. This shared network facilitates the discovery and communication protocols necessary for establishing a casting session. For example, a user attempting to display photos from their Android phone on their Roku-connected television will generally find that the Roku device is only visible within the Android casting options if both devices are on the same Wi-Fi network.
Circumventing the same-network requirement offers increased flexibility in environments where a shared network is unavailable, unreliable, or restricted. Benefits include enabling presentations in locations without guest Wi-Fi, facilitating content sharing in situations where network access is limited, and providing a solution for users who prefer to maintain separate networks for security or performance reasons. Historically, this functionality has been less straightforward, often requiring workarounds or specialized equipment.
