2D applications

The Meta Horizon Store has enabled the integration of 2D Android applications, allowing developers to transition their existing apps from the Google Play Store to Quest headsets without specialized modifications. Users can run 2D applications alongside other programs within Horizon OS, even while using different apps and games. However, many 2D Android applications rely on Google Play Services, which is not available on Horizon OS. Meta plans to introduce a 2D Android version of its Platform SDK to replicate some Google Play Services functionalities, but integrating this SDK may require significant effort from developers. Additionally, developers can use the Meta Spatial SDK to enhance their applications with 3D and mixed reality features, although this is not necessary for porting 2D apps.
