Xdelta is a robust, proven way to deliver small binary updates. On Android, the common solution is to create patches on desktop/CI and apply them on-device with cross-compiled xdelta binaries, wrapped by your app. Key concerns are verifying checksums, handling storage/permissions, and balancing patch compression vs. CPU/time. xdelta patcher android
