+# Burrow Android
+
+The Android app starts as a Kotlin shell linked to `crates/burrow-mobile-ffi`,
+which exposes the cross-platform `burrow-core` crate through JNI.
+
+The current stub proves the package shape and Rust core boundary. Full VPN
+support must use Android `VpnService` and keep platform consent, Play Store
+policy, and disclosure requirements in the release lane.
+
+The Bazel entrypoint is:
+
+```sh
+bazel build //bazel/android:check_stub_stamp
+```
