ADFA-4128 (10/11): gradle-plugin — generating the proxy app

[fryanpan]

ADFA-4128

Part 10/11 of the stacked split of #1669 (requested by Akash). Base: feature/ADFA-4128-qb-09-daemon. Stack overview + review mechanics: PR 1 (#1713). Terms are defined in quickbuild/README.md (lands in PR 1).

Produces the stand-in app that Quick Build reloads into, so it behaves like the user's real app. Ordinary Gradle builds are untouched by it.

What to review

• AndroidIDEGradlePlugin.kt — the property gate; review first, it contains everything else.
• ProxySourceGenerator.kt — which components can be proxied, and each rejection's reason. Line-by-line.
• QuickBuildManifestTransformer.kt — activity-alias synthesis keeps explicit-class navigation resolving.
• QuickBuildJson.kt — SCHEMA_VERSION must move in step with the reader's COMPONENT_SCHEMA_VERSION.
• No :quickbuild:* dependency; this PR's stack position is reading order only.
• QuickBuildPlugin.kt — applied only during provisioning; a revert changes nothing otherwise.

How this PR Was Tested

• 16 test files (15 suites; utils.kt is a helper), including functional Gradle builds asserting real build output.
• TestKit's default arm runs AGP 9.3.1 on Gradle 9.6.1 (AGP_VERSION_LATEST / AGP_VERSION_GRADLE_LATEST, the latter set by PR 2), and the init-script test is parameterised over Gradle 9.5.1 and 9.6.1 (AndroidIDEInitScriptPluginTest.kt:45,59).
• PR head 58d3c8d3d9. :gradle-plugin:test ran on the host at the stack tip 7715c40548 on 2026-09-25: 155 tests, 0 failures, 4 skipped. The four skips are new in this PR, all @Disabled with a ticket in the reason: two because LogSenderPlugin reads variantBuilder.debuggable inside beforeVariants, which the repo's current AGP rejects with PropertyAccessNotAllowedException (fix: ADFA-5433; re-enable: ADFA-5459), and two because the AGP 7.3.0 / Gradle 7.5.1 fixture no longer configures (ADFA-5459). No Quick Build test is skipped; the functional QuickBuildProxyAppBuildTest and the Gradle-version-parameterized init-script test ran in full. CI does not run :gradle-plugin:test; this line is the evidence. Module coverage in the same pass: 46.6% line and 49.1% branch over 1,358 lines and 534 branches. This PR's own 14 of 14 source files, on REVIEW.md section 5's changed-lines non-UI basis, read 57.0% line (602/1056) and 58.9% branch (245/416). Both figures stay depressed by a measurement artifact: TestKit runs the plugin in a separate Gradle process the JaCoCo agent cannot instrument.

Restacked onto stage c263653bcf on 2026-09-24; head now 58d3c8d3d9. The stack carries 1b6ef65622: the init-script plugin test's Gradle matrix moves from 8.14.3 to 9.5.1 and 9.6.1 (AndroidIDEInitScriptPluginTest.kt), for the AGP 9.3.1 minimum. Re-verified at the stack tip 7715c40548 on 2026-09-25, which contains this PR's commits and the roughly 6,970 lines of stage work the restack pulled in: spotlessCheck green (34 of 34 tasks executed, --rerun-tasks) and :app:assembleV8Debug green (254.1 MB APK). The A56 walk ran on 2026-09-24/25 at f6ef914653, that tip plus ADFA-4931's 12 commits: 25 of 25 cases, 24 pass, 0 fail, 1 blocked (T19, Compose — no project on the device configures offline, so Quick Build is never reached). The base is origin/stage's current head, so there is no stage drift. All six unit suites were run once at the stack tip 7715c40548 on 2026-09-25: :quickbuild:core 1,234, :quickbuild:daemon 234, :quickbuild:protocol 22, :quickbuild:runtime 307, :gradle-plugin 155 and :app 1,312 — 3,264 tests, 1 failure and 5 skips. The failure and one skip are :app's (PR 11 has the detail); the other four skips are :gradle-plugin's documented @Disabled cases.

• End-to-end evidence: PR 11.

Coverage (JaCoCo at the stack tip 7715c40548, single run, 2026-09-25). The TOTAL row is re-measured in that pass; the two package rows were last measured 2026-09-22 and are not re-measured here [unmeasured at this head]:

Package	Line	Branch	Note
com.itsaky.androidide.gradle	10.3%	15.9%	plugin entry points; run inside a real Gradle build
com.itsaky.androidide.gradle.quickbuild	69.0%	65.4%	task classes, same
NON-UI TOTAL	46.6%	49.1%	1,358 lines, 534 branches

Both rows are depressed by the TestKit artifact, not by absent tests: this code executes inside a separate real Gradle process that the JaCoCo agent cannot instrument, so the classes exercised only that way read at or near 0%. The per-class breakdown was last measured on 2026-09-14 and not re-measured since [unmeasured at this head]: the classes carrying the artifact were QuickBuildTasks (16.6% over 313 lines; the two task classes with direct unit tests, QuickBuildPayloadTransformTask and the QuickBuildProxyAppReportTask companion, read 100%), QuickBuildPlugin (7.3% over 192), COTGSettingsPlugin (0% over 42), AndroidIDEGradlePlugin (0% over 19), and the pre-existing JdwpPlugin, LogSenderPlugin, ProfilerPlugin and common.kt (0%), with AndroidIDEInitScriptPlugin at 15.7%. The other eight quickbuild files read 100% line, with branch coverage from 70.0% to 100.0%.

📝 Summary

• Adds conditional Quick Build provisioning to the Gradle plugin.
• Generates proxy sources, rewrites manifests, creates activity aliases, and writes Quick Build setup metadata.
• Preserves real manifest names for services and receivers to support explicit intents.
• Adds payload transformation, D8 dexing, baseline-generation stamps, dependency analysis, Compose detection, and resource handling.
• Adds runtime AAR extraction, final-modifier removal, component proxiability checks, and supertype resolution.
• Adds minimum-AGP compatibility checks through minAgpCheck.
• Adds 15 test suites with 149 tests, including functional builds with AGP 8.11.0 and Gradle 8.14.3.
• Risk: Quick Build depends on reflective plugin loading and AGP variant APIs. Unsupported configurations fail the build explicitly.
• Risk: Some compatibility and LogSender tests remain disabled because of AGP and Gradle fixture incompatibilities.
• Best-practice note: End-to-end validation remains deferred to a follow-up change.

Walkthrough

The Gradle plugin now activates Quick Build conditionally, supports multiple AGP versions, transforms manifests, generates proxy sources and payload dex files, writes variant setup metadata, and validates these paths with unit and functional tests.

JSON serialization, proxy generation, resolver behavior, and documentation cover the updated component model.
Payload transformation and generated assets gradle-plugin/src/main/java/com/itsaky/androidide/gradle/quickbuild/..., gradle-plugin/src/test/java/com/itsaky/androidide/gradle/quickbuild/...	Tasks now transform project classes, remove final modifiers, compile and dex proxy sources, extract runtime classes, resolve project supertypes, and write baseline-generation stamps. Unit tests cover archives, malformed inputs, class flags, dex preparation, and supertype traversal.

Merge Risk: 🟡 Moderate · up to b983c

Quick Build proxy apps may fail during startup because the manifest-referenced runtime factory is not packaged. The documentation also gives an incorrect restart rule for rejected library services, so the runtime packaging issue should be fixed before merging.

Align the service and receiver fixtures with the current contract.

The fixture gives the SERVICE and RECEIVER entries a non-null proxyClass. The transformer now records both with proxyClass = null, and ManifestInfo's KDoc states the same. The serializer tests still pass, but the fixture no longer represents a shape the build can emit.

♻️ Proposed refactor

 			ProxiedComponent(
 				type = ComponentType.SERVICE,
 				userClass = "com.example.app.SyncService",
-				proxyClass = "com.example.app.quickbuild.proxies.Proxy0Service",

 			),
 			ProxiedComponent(
 				type = ComponentType.RECEIVER,
 				userClass = "com.example.app.BootReceiver",
-				proxyClass = "com.example.app.quickbuild.proxies.Proxy0Receiver",
+				proxyClass = null,
 			),

Line 171 asserts only the activity's proxyClass, so no assertion needs to change.

The empty-AAR fixture cannot prove the runtime AAR reaches the runtime classpath.

Each test passes an empty temp file as PROPERTY_QUICK_BUILD_RUNTIME_AAR. The plugin only checks isFile, so this fixture satisfies the guard whether or not the dependency actually resolves. Combined with --dry-run, no test here asserts that the injected dependency contributes any file to the variant runtime classpath. Add one assertion that resolves the runtime classpath and finds the injected artifact. That closes the gap described in the QuickBuildPlugin.kt comment about project.fileTree(runtimeAar).

Use @TempDir for the jar fixture.

This test creates its own temp directory and deletes it at the end. If an assertion fails, the cleanup line never runs and the directory stays on disk. The other tests in this cohort take a @TempDir parameter, which JUnit removes after the test in either case.

Reviewed at 9efe5ff against the stacked base feature/ADFA-4128-qb-09-daemon. Governing documents: REVIEW.md (the evidence ledger and the >=50% non-UI coverage bar) and CLAUDE.md (verify-before-you-claim, sweep-the-siblings, docs-in-step-with-code). CLAUDE.md ties the Jira QA transition to "no outstanding critical, high, or medium findings", which is stricter than a default approve rule; one IMPORTANT finding stands, so this round does not clear that bar.

This is careful, unusually well-documented work. The fail-loud/fail-quiet decisions are reasoned per call site rather than uniform, the service/receiver no-rename analysis is correct and the docs were updated in step with it, and the functional tests earn their cost - the config-cache sourceRootDirs test and the "final component from a real dependency" test both pin things only a real Gradle build can prove. SCHEMA_VERSION = 2 was checked against the reader: ProxyAppInfo.COMPONENT_SCHEMA_VERSION = 2 at this head. The findings below are one behavioural gap and a set of claims that do not survive checking.

Findings

#	Severity	Where	Claim
1	IMPORTANT	QuickBuildManifestTransformer.kt:269	synthesized <activity-alias> drops the target's android:permission / android:enabled
2	MINOR	QuickBuildManifestTransformer.kt:147	existing android:appComponentFactory discarded with no record
3	MINOR	AndroidIDEInitScriptPluginTest.kt:91	six tests newly skipped; PR body calls them pre-existing
4	MINOR	build.gradle.kts:166	comment declares a >=90% coverage gate nothing enforces
5	MINOR	QuickBuildTasks.kt:276	KDoc contradicts MIN_PAYLOAD_API on the device API floor
6	MINOR	QuickBuildPlugin.kt:248	null sources.assets fail-quiets the payload dex
7	NITPICK	ClassOpener.kt:32	KDoc claims constant-pool copying that ClassWriter(0) does not do

All seven are CONFIRMED - each was reproduced from the code at head, and findings 2, 3 and 5 from evidence outside the diff (the cached androidx.core AARs, git grep against stage and the base, ResourceSwapStrategyTest). Nothing was dropped for want of an anchor, and nothing is capped as PLAUSIBLE.

Re-check of the CodeRabbit round (5 findings, 2 taken)

• ComponentProxiabilityResolver.kt:68, ASM parse failure -> claimed fixed in 5e98fe39. Fixed. Verified at head: resolve catches RuntimeException and returns Skip("class file for ... could not be read"), and ComponentProxiabilityResolverTest has a dedicated a class file ASM cannot parse skips that component instead of failing the build case. Skip rather than Proxiable is the right call for the reason the reply gives.
• utils.kt:52, repos.txt separator -> claimed fixed in 5e98fe39. Fixed. Reader is File.pathSeparatorChar (utils.kt:52), writer is File.pathSeparator (build.gradle.kts:58) - same character, and the reader can no longer disagree with its writer.
• AndroidIDEInitScriptPlugin.kt:81, logging the classpath -> declined. Agreed, not re-raised. These are app-private paths under logger.info, and the GradleException above already prints an absolute path.
• QuickBuildPlugin.kt:184, fileTree over a single file -> declined. Agreed, not re-raised. Gradle's DirectoryFileTree.visitFrom branches on FileType.RegularFile, and the plugin asserts runtimeAar.isFile at line 133 before this.
• settings.gradle.kts:20, fixture repositories reaching the network -> declined. Agreed, not re-raised. REVIEW.md §11 governs what runs on a user's device; this is src/test/resources resolved by :gradle-plugin:test on a dev machine or CI runner and never ships in the APK.

No prior thread was left open on a live issue, so nothing was unresolved.

Evidence ledger

Area	Evidence
Ticket completeness	ADFA-4128 is the parent spike; this PR is 10/11 of a stacked split scoped to "produce the stand-in app", with end-to-end evidence deferred to PR 11. Scope matches the body. Whole-stack completeness is not assessable here.
§1 Exceptions	New failure paths reviewed at each site. GradleException used for build-stopping errors with actionable messages; IOException swallowed deliberately in SupertypeResolver/findClassBytesInJar with a stated reason. One inconsistency: QuickBuildPlugin.kt:131 throws a bare FileNotFoundException where its two neighbours throw GradleException - cosmetic, not filed.
§2 Leaks	N/A - Gradle plugin, no Android lifecycle.
§3 Threading	N/A - build-time only, no main thread.
§4 Security	newDocumentBuilderFactory disables DOCTYPE, external general/parameter entities and external DTD, with FEATURE_SECURE_PROCESSING on. No secrets. One security-relevant finding: #1, the dropped android:permission.
§5 Tests & coverage	13 test files / 136 tests. Reported 43.1% line / 48.9% branch is below REVIEW.md's >=50%; the TestKit-vs-JaCoCo-agent explanation is sound and the "excluding the four uninstrumentable classes, the other nine read 100% line" breakdown is the right way to show it. See finding #4 on the comment that overstates the gate, and #3 on the six newly skipped tests.
§7 Code quality	No duplication found; ComponentProxiabilityResolver, ClassOpener, SupertypeResolver and RuntimeClassesExtractor are each single-owner. KDoc is present on every public declaration. Findings #2, #4, #5 and #7 are all doc/claim accuracy.
§8-§9 A11y & help	N/A - no UI.
§10 Architecture	N/A for the app's UDF/Koin/Room rules; this is Gradle build logic. The AGP-version split (main compile on the repo's AGP, minAgpCheck source set recompiling the non-Quick-Build sources against AGP_VERSION_MINIMUM, QuickBuildPlugin applied by name so the guard stays honest) is a sound way to hold the compatibility line. QuickBuildPluginTest pins the reflective name to the class.
§13 Plugins	No :plugin-api surface touched.
Sibling sweep	For #1 I checked the other attribute-copy sites: services, receivers and providers are not renamed or aliased, so they keep permission/exported verbatim (asserted by three tests) - the gap is unique to the synthesized activity alias. For #6 I checked both addGeneratedSourceDirectory call sites (lines 248 and 266); variant.sources.java/kotlin at 298-303 are genuinely optional and left alone.

Not filed

• COTGSettingsPlugin no longer adds MAVEN_LOCAL_REPOSITORY in a test env, so -PisTestEnv=true with no mavenLocalRepositories now adds no repository at all where it previously added one. Test-only, and it surfaces as an ordinary resolution failure.
• RuntimeClassesExtractor.extract names outputs <aar-name>-classes.jar, so two AARs sharing a base name would silently collide. The two current inputs (the runtime AAR and the LogSender AAR) cannot collide.
• ProxySourceGeneratorTest's service proxy is an empty subclass covers a shape the transformer no longer produces, since services are never assigned a proxyClass. Harmless coverage of a public API.

Follow-up: findings from the second pass, and one retraction

The background /code-review pass finished after my first review and surfaced five findings I had missed, plus one that corrects me. Everything below was verified against the code at 9efe5ff before posting; I did not take the second pass's conclusions on trust, and two of its nine did not survive that check (see the bottom).

Retracted

QuickBuildManifestTransformer.kt:147, the appComponentFactory overwrite - withdrawn, replied on the thread. replaces a library-injected appComponentFactory with the quick build factory (QuickBuildManifestTransformerTest.kt:882) pins the behaviour deliberately and its comment already names androidx.core.app.CoreComponentFactory and explains why it must not survive. My suggestion to keep the old value for chaining was wrong - chaining would defeat the payload-loader routing. My apologies for the noise.

Added this round

#	Severity	Where	Claim
8	IMPORTANT	QuickBuildManifestTransformer.kt:83	a skipped launcher activity leaves entryActivity: null; the isLauncher fact is discarded
9	IMPORTANT	QuickBuildTasks.kt:646	firstOrNull() picks an arbitrary split APK; wrong-ABI install
10	MINOR	QuickBuildTasks.kt:184	copyRecursively / JarFile throw on an absent entry, where the sibling path tolerates it
11	NITPICK	ComponentProxiabilityResolver.kt:107	three reasons justify themselves against a rename that can no longer happen
12	NITPICK	QuickBuildManifestTransformer.kt:224	skipped activity keeps shorthand android:name; the other two sites normalise
13	NITPICK	utils.kt:33	tab conversion collapsed all nesting depth

Also added as a reply on the AndroidIDEInitScriptPluginTest.kt:91 thread rather than a new one, since it concerns the same disabled test: common.kt:67's onDebuggableVariants reads variantBuilder.debuggable inside beforeVariants, and LogSenderPlugin.kt:73 and JdwpPlugin.kt:30 both use it. QuickBuildPlugin.kt:153-156 documents in this PR's own words that AGP 8.11 answers that read with PropertyAccessNotAllowedException under CoGo's init script, which is why the new code avoids the helper. If that diagnosis holds, every CoGo build with LogSender or JDWP enabled fails at configuration time on the current AGP, JdwpPlugin included though no disabled test names it. The defect is outside this diff and fair to keep out of scope - but the @Disabled reasons should then cite a ticket, so six skipped tests have an owner rather than a comment.

From the second pass, not filed

• COTGSettingsPlugin.kt:36, isTestEnv=true with no mavenLocalRepositories now adds no repository where it previously added one. Real, but test-env-only and it surfaces as an ordinary resolution failure; already listed under "Not filed" in my first review.
• ClassOpener.kt:81, openJar not tolerating duplicate entry names or a non-zip input. The tolerance argument is fair, but the inputs are this build's own payload-classes/jars/N.jar, written by divert() from AGP artifacts one line earlier - not third-party jars - so I could not name a reachable input. Left alone deliberately.

Verified and cleared by the second pass

Recording these so the next reviewer does not redo them: MIN_PAYLOAD_API = 30's claim that the emitted dex loads on API 28+ (checked empirically - d8 --min-api {28,30,34} all emit dex 039); project.fileTree(runtimeAar) over a regular file; COGO_GRADLE_PLUGIN_PATH/_JAR_NAME resolving to the same on-device path as the removed literal and matching archiveBaseName = "cogo-plugin"; the report task's implicit task dependencies (the @Input path properties are set from flatMapped task outputs, which carry producer information); and composeEnabled / annotationProcessors under the configuration cache.

Running total

1 retracted, 12 standing: 3 IMPORTANT, 4 MINOR, 5 NITPICK. The verdict is unchanged in direction but firmer - REQUEST_CHANGES, on findings 1, 8 and 9. Findings 8 and 9 are the two I would fix first: both are silent, both end in "the app does not start" on a user's device, and both are cheap.
