What

--filter-plugins-devices-arch passes the same -PabiFilters=<abis> that #6130 computes for the app build to the gradle build of every plugin built from source.

A plugin with a long native build - an NDK/CMake one - can then build one ABI instead of four when a run is only going to deploy to one device.

Stacked on #6130

This branch is based on #6130 and its diff contains that PR's commit until it merges - the reviewable commit here is the second one, 5ecb7c0. It cannot stand alone: the ABIs come from deviceInfo.abis, which #6130 adds. The device selection those two PRs share moved into lib/services/android/devices-abis.ts, so GradleBuildService and the plugin path compute the ABI set the same way instead of twice.

It is a separate PR because it is a separate decision: #6130 narrows the app build on by default, this narrows plugin builds only when asked.

Why there is no gradle block for it

Nothing in the gradle files the CLI generates for a plugin acts on abiFilters, and this deliberately does not add such a block. What a plugin's native sources need per ABI is the plugin's business - a splits block would be wrong for a plugin producing an .aar, and an ndk.abiFilters block would silently change what every existing plugin builds.

The property is passed so that a plugin whose own include.gradle reads it can act on it. A plugin that ignores it builds exactly what it built before.

Why it is off by default

Unlike the app-side narrowing, a narrowed .aar is a partial artifact that stays in platforms/tempPlugin and in the plugin's platforms/android directory, and the rebuild decision is keyed by the plugin sources - which do not change when a device with another ABI joins the run.

So the ABI set is now part of the plugin build data that decision reads (__abiFilters in .ns-plugin-build-data.json). Changing devices, or turning the flag back off, rebuilds the aar. Off by default keeps that cost out of the way of anyone who does not need it.

An explicit -PabiFilters in the gradle args still wins.

Tests

npm test — 1866 passing (1862 on #6130). Four cases in test/services/android-project-service.ts covering the ABIs handed to buildAar: all devices, --device, the option off, and devices that report no ABIs.

Notes

From https://github.com/Akylas/nativescript-cli, in production use there.

Merge order: after #6130. Expect small textual conflicts with #6129 (IAndroidBuildOptions.gradleArgs and the options object in android-project-service) and with #6132, whose android.plugins map is the natural home for a later per-plugin override of this flag.

A `ns run android` with a single arm64 device still builds every ABI. This
narrows the native build down to the ABIs of the devices it is about to
deploy to, and picks the matching package when installing.

- `GradleBuildService` passes `-PabiFilters=<abis>` built from the devices
  the build targets (honouring `--device`/`--emulator`). The app's gradle
  configuration decides what to do with it - typically an `ndk.abiFilters`
  or `splits` block in `App_Resources/Android/app.gradle`. An explicit
  `-PabiFilters` in `--gradleArgs` always wins.
- `--no-filter-devices-arch` turns the narrowing off. `ns build` never
  narrows, since its artifact is meant to be shipped, and neither does an
  app bundle build, which carries every ABI anyway.
- `Mobile.IDeviceInfo` gained `abis`, read on android from
  `ro.product.cpu.abilist64`/`abilist32`, falling back to
  `ro.product.cpu.abi` on old devices.
- `AndroidProjectService.checkForChanges` marks the native project as
  changed when a connected device has no package of its own in the build
  output - a device that joins later would otherwise never get one, as the
  sources did not change.
- `DeviceInstallAppService` installs the package matching the device's
  ABIs, falling back to the universal one and then to the newest package.
- `copyLatestAppPackage` became `copyAppPackages`: a directory `--copy-to`
  target receives every package the build produced, a single file target
  receives the universal one.

`--filter-plugins-devices-arch` passes the same `-PabiFilters` the app build
gets to the gradle build of every plugin built from source.

Nothing in the gradle files the CLI generates for a plugin acts on the
property, and this deliberately does not add such a block: what a plugin's
native sources need per ABI is the plugin's business. It is there for a plugin
whose own `include.gradle` reads `abiFilters` - a plugin with a long native
build (an NDK/CMake one, say) can then build only the ABIs this run is about
to deploy to instead of all four.

Off by default. A narrowed aar is a partial artifact and the aar cache is
keyed by the plugin sources, which do not change when a device with another
ABI joins, so the ABIs are now part of the plugin build data the rebuild
decision reads.

📝 Walkthrough

Walkthrough

Android builds and plugin builds now support device ABI filtering. Package copying and installation select compatible outputs. Device ABI data, build options, service contracts, tests, and Android command documentation were updated.

Changes

Android ABI flow

Layer / File(s) Summary
ABI options and device data contracts
lib/options.ts, lib/declarations.d.ts, lib/definitions/android-plugin-migrator.d.ts, lib/common/definitions/mobile.d.ts, lib/common/mobile/android/android-device.ts, lib/services/android/devices-abis.ts
Adds application and plugin ABI-filter options. Android device data now exposes ordered ABI lists. A helper returns unique device ABIs.
Application ABI filtering
lib/commands/build.ts, lib/data/build-data.ts, lib/definitions/build.d.ts, lib/services/android/gradle-build-service.ts, test/services/android/gradle-build-service.ts, docs/man_pages/project/testing/debug-android.md, docs/man_pages/project/testing/run-android.md
Build data controls device ABI filtering. Gradle builds derive connected-device ABIs unless filtering is disabled or an explicit filter exists. Tests cover device, emulator, duplicate, disabled, and missing-ABI cases.
Plugin ABI propagation and change detection
lib/services/android-project-service.ts, lib/services/android-plugin-build-service.ts, test/services/android-project-service.ts, test/plugins-service.ts
Plugin builds receive connected-device ABI filters and include them in cache data. Project change checks detect missing ABI-specific APKs. Tests cover plugin filtering and new service dependencies.
Package copying and device installation
lib/definitions/build.d.ts, lib/services/build-artifacts-service.ts, lib/controllers/build-controller.ts, lib/services/device/device-install-app-service.ts
Renames the artifact copy method and supports multiple packages. Installation selects a matching ABI package, then a universal package, then the latest package.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to 5ecb7

The change can select the wrong device ABI, reuse a plugin artifact built for a stale ABI selection, fail when creating copy targets, or mishandle ABI-only APK outputs, causing Android builds or installs to fail or use incompatible artifacts. These correctness issues make the PR unsafe to merge until fixed.

Poem

I’m a rabbit with ABIs in line,
Building arm64 outputs fine.
Plugins filter, packages hop,
Universal waits at the top.
Tests check each device’s trail—
Build and install without fail.

- Around line 16-18: Update getAbis to parse cpu.abilist first and preserve its
complete ordering; only fall back to concatenating cpu.abilist64 and
cpu.abilist32 when cpu.abilist is absent. Ensure getDevicesAbis therefore
selects the first ABI from the declared preference list, and add regression
coverage for both the full ABI list and selected ABI.

In `@lib/services/android-plugin-build-service.ts`:
- Around line 242-246: Resolve the effective ABI filter, including any exact
-PabiFilters Gradle property override, before shouldBuildAar and store that
resolved value under AndroidPluginBuildService.ABI_FILTERS_BUILD_DATA_KEY
(__abiFilters). Match the property name exactly so -PabiFiltersExtra cannot
override it, and add regression coverage confirming that changing an explicit
ABI filter with unchanged sources rebuilds the plugin.

In `@lib/services/android/gradle-build-service.ts`:
- Around line 75-76: Update the buildTaskArgs check in the Gradle build service
to match only arguments beginning with "-PabiFilters=", not any string sharing
the "-PabiFilters" prefix, and add a regression test covering a similarly
prefixed unrelated argument such as "-PabiFiltersBackup=value".

In `@lib/services/build-artifacts-service.ts`:
- Around line 98-103: Update the target-directory setup in the build-artifacts
copy flow to create the directory identified by targetIsDirectory before copying
packages, while retaining parent-directory creation for file targets. Use the
existing $fs.ensureDirectoryExists and targetPath classification logic so
extensionless targets such as artifacts/apks exist before the first package
copy.
- Around line 105-112: Update the single-file target handling in
lib/services/build-artifacts-service.ts lines 105-112 to detect when filtering
applicationPackages leaves no universal package, then fail with guidance to
select a directory target. Also update the package-selection logic in
lib/services/device/device-install-app-service.ts lines 114-136 to fail when
neither a device-ABI match nor a universal package exists, rather than
installing the newest unmatched package; preserve normal ABI and universal
selection behavior.

Preserve the full device ABI preference order.

getAbis currently places cpu.abilist64 before cpu.abilist. Android defines cross-bitness preference order through ro.product.cpu.abilist. getDevicesAbis selects deviceInfo.abis[0], so cpu.abilist=armeabi-v7a,arm64-v8a selects the wrong ABI. Parse cpu.abilist first and use the 64-bit/32-bit concatenation only when it is absent. Add regression coverage for the full ABI list and selected ABI.

Cache the effective ABI filter and match the exact Gradle property.

Lines 242-246 store options.abiFilters before Lines 840-847 apply the explicit override. If a plugin was already built with automatic arm64-v8a filters, a later -PabiFilters=x86_64 uses the same cache key and skips buildPlugin. The plugin AAR then remains built for arm64-v8a.

Resolve the effective ABI filter before shouldBuildAar. Store that value in __abiFilters. Match -PabiFilters as an exact Gradle property. Do not treat -PabiFiltersExtra as an override. Add regression coverage for changing an explicit ABI filter with unchanged sources.

🧩 Analysis chain

🌐 Web query:

According to the supported Gradle version, what command-line forms set a project property with -P, and is -PabiFilters=value the required form for this CLI?

💡 Result:

To set a project property via the Gradle command-line interface, you use the -P or --project-prop option followed by the property name and its value [1][2]. The correct syntax is -PpropertyName=value [1][2]. Regarding your specific example, -PabiFilters=value is a valid and correct command-line form to set a project property named abiFilters to the specified value [1][2]. Gradle also supports other ways to set project properties if you do not wish to use the -P command-line flag, such as: 1. System Properties: You can set a system property using -Dorg.gradle.project.propertyName=value [2][3][4]. 2. Environment Variables: You can set an environment variable named ORG_GRADLE_PROJECT_propertyName=value [2][3][4]. 3. Gradle Properties Files: You can define the property in a gradle.properties file located in your project root or Gradle user home directory [3][4].

Match the abiFilters property name exactly.

startsWith("-PabiFilters") also matches unrelated arguments such as -PabiFiltersBackup=value. This prevents the service from adding the actual ABI filter. Match -PabiFilters= and add a regression test.

Create a new directory target before copying packages.

In `@lib/services/build-artifacts-service.ts` around lines 98 - 103, Update the
target-directory setup in the build-artifacts copy flow to create the directory
identified by targetIsDirectory before copying packages, while retaining
parent-directory creation for file targets. Use the existing
$fs.ensureDirectoryExists and targetPath classification logic so extensionless
targets such as artifacts/apks exist before the first package copy.

Handle split-only output without assuming a universal APK exists.

Both sites assume that ABI-split builds include a universal package. A Gradle configuration can produce only ABI-specific APKs.

  • lib/services/build-artifacts-service.ts#L105-L112: fail when a single-file target has no universal package, and instruct the user to select a directory target.
  • lib/services/device/device-install-app-service.ts#L114-L136: fail when no package matches the device ABI and no universal package exists. Do not install the newest unmatched package.

In `@lib/services/build-artifacts-service.ts` around lines 105 - 112, Update the
single-file target handling in lib/services/build-artifacts-service.ts lines
105-112 to detect when filtering applicationPackages leaves no universal
package, then fail with guidance to select a directory target. Also update the
package-selection logic in lib/services/device/device-install-app-service.ts
lines 114-136 to fail when neither a device-ABI match nor a universal package
exists, rather than installing the newest unmatched package; preserve normal ABI
and universal selection behavior.
