Fixes ADFA-2354 and ADFA-2356.

Problem

The shipped SDK's platform-tools/adb is a 0-byte stub and adb cannot run on the device, so AGP's install<Variant> / uninstall<Variant> tasks fail with Cannot run program ".../adb": Exec failed, error: 13 (Permission denied).

Change

  • gradle-plugin: replaces the actions of every AGP InstallVariantTask / UninstallTask with a lifecycle message. Main-variant install and uninstall succeed with the message; *AndroidTest variants fail with a clear message (nothing installs test APKs on device). Dependencies are kept, so installDebug still builds the APK. Matched by task class, not name, so user tasks named install* are untouched; matching by task group does not work because the init script's afterEvaluate runs before AGP sets it.
  • IDE: RunTasksDialogFragment routes selections containing install<Variant> through BuildViewModel.runTasks, which resolves the app-module variant by assembleTaskName, reads the APK from the output listing and hands it to CoGo's installer (AwaitingInstall, no auto-launch). Other selections keep going straight to the build service.

Verification

  • On emulator (Pixel_9_Pro, arm64), My Application24: :app:installDebug builds, prints the message, CoGo's installer prompt installs the app; :app:uninstallDebug prints its message and succeeds. Before/after recordings in the ticket.
  • InstallTaskRequestTest (6 tests). The gradle-plugin TestKit harness cannot run (nothing writes repos.txt since the plugin moved to cogo-plugin.jar), so the plugin half is verified on device.
  • No UI layout change, so no font-scale check.

Not covered

Apps declared on the root project keep AGP's adb action: the init script applies the IDE plugin to subprojects only (pre-existing, same for LogSender/JDWP).

The shipped SDK has a 0-byte platform-tools/adb stub and adb cannot run on
the device, so AGP's install<Variant>/uninstall<Variant> tasks fail with
"Exec failed, error: 13 (Permission denied)".

The IDE plugin now replaces the actions of every AGP InstallVariantTask and
UninstallTask with a lifecycle message. Main-variant install and uninstall
succeed with the message (the IDE takes over installing); *AndroidTest
variants fail with a clear message because nothing installs test APKs on
device. Task dependencies are kept, so installDebug still builds the APK.

Matched by task class rather than name so user tasks named install* are
untouched and com.android.test modules are covered. Matching on task group
does not work here: the init script applies this plugin from an afterEvaluate
registered in projectsLoaded, which runs before AGP's own afterEvaluate sets
the group.

Also fixes ADFA-2356 (uninstall permission denied).
RunTasksDialogFragment routes any selection containing an install<Variant>
task through BuildViewModel.runTasks. After the build succeeds it picks the
app-module variant whose assembleTaskName is assemble<Variant>, reads the APK
from the output listing and emits BuildState.AwaitingInstall, so the existing
installer flow installs it. The app is not launched automatically.

Non-install selections keep going straight to the build service. The
InProgress slot claim and terminal-state reporting are shared with
runQuickBuild (claimBuildSlot, RunReporter); no behaviour change there.

Verified on device: installDebug builds, prints the plugin message, and CoGo
installs the APK; uninstallDebug prints its message and succeeds.

Review Change Stack

📝 Summary
  • Replaced AGP install<Variant> and uninstall<Variant> ADB actions with lifecycle messages while preserving dependencies.
  • Routed only app-variant install tasks through CoGo APK installation without automatic launch.
  • Added variant-aware APK resolution for nested modules.
  • Preserved existing behavior for non-variant tasks and user-defined install* tasks.
  • Added clear unsupported messages for Android test variants.
  • Reported rejected install requests without closing the dialog.
  • Added tests for parsing, routing, failure handling, task replacement, dependencies, and unaffected tasks.
  • Risk: Multiple install tasks can produce ambiguous APK selection.
  • Limitation: Android test APKs are not installed on the device.

Walkthrough

The change adds install-task parsing, routes install tasks through BuildViewModel, resolves generated APKs, centralizes build-state reporting, and replaces unsupported Gradle ADB task actions with messages or errors.

Changes

Install task execution

Layer / File(s) Summary
Gradle task replacement
gradle-plugin/src/main/java/com/itsaky/androidide/gradle/*, gradle-plugin/src/test/java/com/itsaky/androidide/gradle/InstallTaskReplacementTest.kt
The plugin identifies unsupported install, uninstall, and Android test tasks. It removes matching task actions and logs a replacement message or throws an exception. Tests cover detection, action replacement, custom tasks, and dependency preservation.
Task classification and routing
app/src/main/java/com/itsaky/androidide/models/InstallTaskRequest.kt, app/src/main/java/com/itsaky/androidide/fragments/RunTasksDialogFragment.kt, app/src/test/java/com/itsaky/androidide/models/InstallTaskRequestTest.kt
Install task names produce module-aware requests. The task dialog sends install requests to BuildViewModel and keeps direct execution for other tasks. Tests cover valid and invalid task names.
Build execution and APK resolution
app/src/main/java/com/itsaky/androidide/viewmodel/BuildViewModel.kt, app/src/test/java/com/itsaky/androidide/viewmodel/*, app/src/test/java/com/itsaky/androidide/viewmodel/MainDispatcherRule.kt
BuildViewModel claims build slots, reports terminal states, executes tasks, resolves matching APK outputs, and handles cancellation and errors. Tests cover routing, slot claiming, missing services, null results, and final error states.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 19fa1

Install and uninstall task handling now bypasses unavailable ADB actions and routes app install builds through the IDE installer. An exception can still leave builds permanently marked in progress, and incomplete test isolation and assertions leave regressions insufficiently guarded; resolve these before merging.

runTasks now returns whether the build slot was claimed. When another build
is in progress the task dialog flashes the existing "build in progress"
message and stays open instead of dismissing and silently dropping the
selected install task.

Tests:
- BuildViewModelTest: runTasks is refused and reported while a build is
  queued, claims the slot before its coroutine runs, and ends in a single
  reported error when no build service is registered.
- InstallTaskReplacementTest (gradle-plugin, ProjectBuilder): AGP
  InstallVariantTask/UninstallTask are recognised by class and their action
  replaced by one message action, *AndroidTest install tasks fail with the
  unsupported message, a user task named install* keeps its own actions, and
  task dependencies survive the replacement.

MainDispatcherRule exposes its dispatcher so tests can advance it.

The IDE half matched any task named install<Capital>, so :installDist or
:app:installGitHooks went through runTasks and, after a successful build,
hit "No Android application variant is assembled by ..." and a red error.
Review feedback from jatezzz and dara-abijo-adfa.

BuildViewModel now resolves an install task to an app-module variant by
assembleTaskName up front (installsAnAppVariant); the task dialog routes to
the installer only when that resolves, and the post-build lookup returns null
instead of throwing, so non-variant install tasks behave exactly as before.
The project manager is injected as a provider so this is unit-testable.

Also restores the result == null guard that runQuickBuild has for the same
executeTasks future, so a null JSON-RPC result reports the failure instead of
an NPE-turned-"unknown error".
