feat(install): support Porter through its Shizuku-API bridge

[d4rken]

What changed

The Shizuku engine can now run on Porter, a maintained Shizuku fork, when Porter is installed and running. Without Porter, Shizuku works as before. When Porter is the only one installed, settings and the home banner name and open Porter.

Supersedes #145 by @RedJJ94, whose commits are kept here and who is credited as co-author. It was built on Porter SDK 0.1.0, which current Porter no longer detects.

Technical Context

• shizuku-bridge (porter-api 0.8.0, JitPack) is started in App.onCreate and serves rikka.shizuku.Shizuku from a running Porter, so Ackpine's Shizuku installs need no separate path. ShizukuProvider stays.
• A connected Porter takes precedence over a Shizuku binder. If Porter stops while the app runs, the app falls back until its next start, even with Shizuku running: a running Shizuku server only delivers its binder to a new app process.
• Added Porter support #145's capability substitution, provider swap and backend selector are dropped; its "Shizuku, Porter, or Root" wording is kept.

Summary by CodeRabbit

• New Features
  • Added support for Porter as an alternative Shizuku-compatible service for privileged installation tasks.
  • Porter-specific guidance now appears when permission is needed or the service isn’t running, with an option to open Porter.
  • Settings and prompts now list Porter alongside Shizuku and Root where applicable.

📝 Walkthrough

Walkthrough

The app adds Porter as a Shizuku API backend. It starts the Porter bridge, detects Porter installation and backend status, and updates service-start behavior and related user-facing text.

Changes

Porter backend integration

Layer / File(s)	Summary
Bridge setup and service detection gradle/libs.versions.toml, settings.gradle.kts, app/build.gradle.kts, app/src/main/java/app/pwhs/universalinstaller/Application.kt, app/src/main/java/app/pwhs/universalinstaller/util/ShizukuServices.kt	Adds the Porter bridge dependency and repository filter, starts the bridge during app initialization, and adds shared checks for Porter and Shizuku installation and active backend status.
Privilege and service-start handling app/src/main/java/app/pwhs/universalinstaller/presentation/setting/util/SettingPrivilegeDelegate.kt, app/src/main/java/app/pwhs/universalinstaller/presentation/setting/util/SettingDefaultRoleDelegate.kt, app/src/main/java/app/pwhs/universalinstaller/presentation/composable/InstallPriorityActionHandler.kt, app/src/main/res/values/strings_settings.xml	Privilege and install actions select service-start hints based on the installed backend. The Porter-only path emits a Porter hint and launches Porter when a launch intent exists.
Porter status and user-facing text app/src/main/java/app/pwhs/universalinstaller/presentation/install/components/ShizukuPromoBanner.kt, app/src/main/java/app/pwhs/universalinstaller/presentation/setting/components/InstallModeSelector.kt, app/src/main/java/app/pwhs/universalinstaller/presentation/setting/components/InstallPriorityList.kt, app/src/main/res/values/strings_install.xml, app/src/main/res/values/strings_manage.xml, app/src/main/res/values/strings_settings.xml, README.md	The banner and settings views show Porter-specific status text where applicable. Installation guidance, privileged-access prompts, and README descriptions include Porter.

Merge Risk: 🔵 Low · up to 0c302

If Porter connects slowly during startup, users may need to select Shizuku again. This is a bounded, recoverable risk, but coordinating startup with self-heal is advisable before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 0c302

A delayed Porter connection can cause the app to turn off a saved Shizuku installer choice before Porter becomes ready. Existing install-time permission checks remain in place, but the new bridge’s identity and recovery behavior could not be fully verified.

Retained concerns

• Medium · reliability · inferred: If Porter supplies its binder after self-heal’s readiness window, self-heal can clear a saved Shizuku backend choice. A subsequent binder connection updates readiness but does not restore that choice, leaving installer selection different from the user’s saved intent until it is selected again.

Security review details

Security Blast Radius

• inferred — The new bridge can affect installs that select the shared Shizuku controller throughout this app process, rather than only Porter-specific settings screens. The available evidence does not establish exposure beyond that process or a cross-device boundary.

Trust Boundaries and Controls

• observed — Before normal Ackpine Shizuku controller selection, the app requires a responsive binder, a supported Shizuku API and granted self-permission. Whether the external bridge independently binds those results to an authenticated Porter connection is not shown.

Resilience and Maintainability Implications

• inferred — The bounded readiness check can turn a temporary provider-start delay into persistent backend-selection drift. Live readiness checks contain installation attempts while the binder is unavailable, but do not by themselves restore the saved preference after recovery.

Hardening Proposals

• proposed — Coordinate preference self-heal with completion or definitive failure of Porter connection, and verify the bridge’s provider identity, permission binding and binder-death recovery contract before treating its connection as installer authority.
