📝 Walkthrough

The Gradle build now uses version-catalog values for Android SDK settings and plugin aliases. Version-code parsing uses a zero fallback, and both app flavors reuse the computed value. App sources import the ViewBinding delegate from dev.androidbroadcast.vbpd.

Changes: Android build and ViewBinding updates

Layer / File(s)	Summary
Catalog values and plugin setup gradle/lib.toml, build.gradle.kts, benchmark/build.gradle.kts, gradle.properties	The catalog adds Android SDK values, updates the ViewBinding delegate version, and defines plugin aliases. The root build removes plugin classpath dependencies. The benchmark module uses catalog plugin and SDK values. Gradle properties update the configuration-cache setting and remove the AndroidX setting and related comments.
App build configuration and version handling app/build.gradle.kts	The app build uses catalog plugin aliases and SDK values, and derives the Kotlin language version from the configured Kotlin version. Version-code parsing uses the provider API and returns 0 when parsing fails. Both flavors reuse the computed code. The download configuration uses direct creation. Both flavors use dev.androidbroadcast.vbpd.
ViewBinding import migration app/src/**	Affected activities, fragments, dialogs, and bottom sheets import the ViewBinding delegate from dev.androidbroadcast.vbpd. Their binding declarations and described behavior remain unchanged.

Merge Risk: 🔵 Low · up to 42546

A malformed version-code setting can hide the in-app new-version notice, but the app’s update checks remain unaffected. The remaining risk is bounded.

Security architecture risk: 🔵 Low · up to 42546

The checked-in release version is valid, and the dependency migration appears contained. However, an invalid release-version setting can now produce an app that skips version migrations and conditional privacy setup instead of stopping the build. Whether such an input can reach a distributed release is unknown.

Retained concerns

• Medium · security · inferred: A malformed Gradle VERSION_CODE property now yields BASE_VERSION_CODE=0 rather than failing configuration. If that artifact is distributed, the runtime version gate skips migrations and conditional privacy initialization until a corrected version is installed. Actual exposure through a release input was not established.

Security review details

Security Blast Radius

• inferred — The conditional version-code issue spans full and tv release types and their channel combinations, but requires a malformed build property and distribution of the resulting artifact. No remotely supplied app input or affected release was established.

Security Findings and Attack Paths

• inferred — A malformed release property can pass the build boundary as a zero base version and suppress conditional privacy setup and stored-setting migrations. This is a configuration-to-artifact failure path, not a verified external attacker path; normal eligible update checks remain reachable.

Trust Boundaries and Controls

• observed — The build supplies BASE_VERSION_CODE to runtime code, which treats zero as “not a new version.” The checked-in Gradle property supplies 69; the reviewed evidence does not establish an invalid production input.

Resilience and Maintainability Implications

• inferred — Repeated launches do not repair a zero-version artifact’s skipped migration state. A corrected artifact may resume migration, while the separately gated Play or website update check can still discover an update.

Hardening Proposals

• proposed — Reject absent, malformed, or zero release-version inputs before producing distributable variants, and verify the generated base version in release validation.

Reject invalid VERSION_CODE values.

A malformed Gradle property currently becomes 0. The full and tv flavors pass that value to versionCode and BuildConfig.BASE_VERSION_CODE. Android requires a positive versionCode. If such a value is packaged, RestoreAgent.isNewVersion() also treats it as “not new.”

Before this change, malformed properties failed during configuration. Reject them instead of silently producing 0.

Suggested fix

-        code = project.providers.gradleProperty("VERSION_CODE").get().toIntOrNull() ?: 0
+        code = project.providers.gradleProperty("VERSION_CODE").get().toIntOrNull()
+            ?.takeIf { it > 0 }
+            ?: error("VERSION_CODE must be a positive integer")
