binder

Call Android system services from pure Go. Provides ~14,000 type-safe Go methods across 1,500+ Android interfaces — ActivityManager, PowerManager, SurfaceFlinger, PackageManager, audio, camera and sensor HALs, and more — by speaking the Binder IPC wire protocol directly via /dev/binder ioctl syscalls. No Java, no NDK, no cgo required.

Includes a complete AIDL compiler that parses Android Interface Definition Language files and generates the Go proxies, a version-aware runtime that adapts transaction codes across Android API levels, and a CLI tool (bindercli) for interactive service discovery and invocation.

What can it do?

• Query system services — battery level, GPS location, thermal status, running processes, installed packages
• Control hardware — connect to WiFi, toggle flashlight, manage Bluetooth, configure audio
• Interact with any binder service — ActivityManager, PowerManager, SurfaceFlinger, camera/sensor HALs, and more
• No Java, no cgo — pure Go, cross-compiles to a static binary, runs on Android or any Linux with /dev/binder
• CLI tool included — bindercli for interactive service discovery, method invocation, and debugging

Quick start

Go library — go get github.com/AndroidGoLab/binder — live GPS location via binder IPC:

package main

import (
    "context"
    "fmt"
    "math"
    "os"
    "time"

    "github.com/AndroidGoLab/binder/android/location"

    "github.com/AndroidGoLab/binder/servicemanager"
)

// gpsListener receives location callbacks from the LocationManager.
type gpsListener struct{ fixCh chan location.Location }

func (l *gpsListener) OnLocationChanged(_ context.Context, locs []location.Location, _ androidos.IRemoteCallback) error {
    for _, loc := range locs { select { case l.fixCh <- loc: default: } }
    return nil
}
func (l *gpsListener) OnProviderEnabledChanged(_ context.Context, _ string, _ bool) error { return nil }
func (l *gpsListener) OnFlushComplete(_ context.Context, _ int32) error                   { return nil }

func main() {
    ctx := context.Background()
    drv, _ := kernelbinder.Open(ctx, binder.WithMapSize(128*1024))
    defer drv.Close(ctx)
    transport, _ := versionaware.NewTransport(ctx, drv, 0)
    sm := servicemanager.New(transport)

    lm, _ := location.GetLocationManager(ctx, sm)

    impl := &gpsListener{fixCh: make(chan location.Location, 1)}
    listener := location.NewLocationListenerStub(impl)

    request := location.LocationRequest{
        Provider: location.GpsProvider, IntervalMillis: 1000,
        ExpireAtRealtimeMillis: math.MaxInt64, DurationMillis: math.MaxInt64,
    }
    pkg := binder.DefaultCallerIdentity().PackageName
    _ = lm.RegisterLocationListener(ctx, location.GpsProvider, request, listener, pkg, "gps")
    defer lm.UnregisterLocationListener(ctx, listener)

    select {
    case loc := <-impl.fixCh:
        fmt.Printf("Lat: %.6f  Lon: %.6f  Alt: %.1f m  Accuracy: %.1f m\n",
            loc.LatitudeDegrees, loc.LongitudeDegrees, loc.AltitudeMeters, loc.HorizontalAccuracyMeters)
    case <-time.After(30 * time.Second):
        fmt.Fprintln(os.Stderr, "timed out")
    }
}

Full runnable example: examples/gps_location/

Or query power state:

power, _ := os.GetPowerManager(ctx, sm)
interactive, _ := power.IsInteractive(ctx)
fmt.Printf("Screen on: %v\n", interactive)

Loading

Library	Interface	Requires	Best for
ndk	Android NDK C APIs	cgo + NDK toolchain	High-performance hardware access: camera, audio, sensors, OpenGL/Vulkan, media codecs
jni	Java Android SDK via JNI	cgo + JNI + JVM/ART	Java-only APIs with no NDK equivalent: Bluetooth, WiFi, NFC, location, telephony, content providers
binder (this project)	Binder IPC (system services)	pure Go (no cgo)	Direct system service calls without Java: works on non-Android Linux with binder, minimal footprint

When to use which

• Start with ndk when the NDK provides a C API for what you need (camera, audio, sensors, EGL/Vulkan, media codecs). These are the lowest-latency, lowest-overhead bindings since they go straight from Go to the C library via cgo.

• Use jni when you need a Java Android SDK API that the NDK does not expose. Examples: Bluetooth discovery, WiFi P2P, NFC tag reading, location services, telephony, content providers, notifications. JNI is also the right choice when you need to interact with Java components (Activities, Services, BroadcastReceivers) or when you need the gRPC remote-access layer.

• Use binder when you want pure-Go access to Android system services without any cgo dependency. This is ideal for lightweight tools, CLI programs, or scenarios where you want to talk to the binder driver from a non-Android Linux system. AIDL covers the same system services that Java SDK wraps (ActivityManager, PowerManager, etc.) but at the wire-protocol level.

• Combine them when your application needs multiple layers. For example, a streaming app might use ndk for camera capture and audio encoding, jni for Bluetooth controller discovery, and binder for querying battery status from a companion daemon.

How they relate to each other

All three libraries talk to the same Android system services, but through different paths:

• The NDK C APIs are provided by Google as stable C interfaces to Android platform features. Some (camera, sensors, audio) internally use binder IPC to talk to system services; others (EGL, Vulkan, OpenGL) talk directly to kernel drivers. The ndk library wraps these C APIs via cgo.
• The Java SDK uses binder IPC internally for system service access (BluetoothManager, LocationManager, etc.), routing calls through the Android Runtime (ART/Dalvik). The jni library calls into these Java APIs via the JNI C interface and cgo.
• The AIDL binder protocol is the underlying IPC mechanism that system-facing NDK and Java SDK APIs use. The binder library implements this protocol directly in pure Go, bypassing both C and Java layers entirely.

Register a Server-Side Service

import (
    "context"

    "github.com/AndroidGoLab/binder/binder"
    "github.com/AndroidGoLab/binder/parcel"
    "github.com/AndroidGoLab/binder/servicemanager"
)

// myService implements binder.TransactionReceiver for a simple ping service.
type myService struct{}

func (s *myService) Descriptor() string { return "com.example.IPingService" }

func (s *myService) OnTransaction(
    ctx context.Context,
    code binder.TransactionCode,
    data *parcel.Parcel,
) (*parcel.Parcel, error) {
    reply := parcel.New()
    binder.WriteStatus(reply, nil)
    reply.WriteString16("pong")
    return reply, nil
}

    // Register with ServiceManager
    err := sm.AddService(ctx, servicemanager.ServiceName("my.service"), &myService{}, false, 0)

Using other services

The examples above cover specific subsystems, but the library supports all Android binder services — over 1,500 interfaces. To work with a service not shown above:

1. Find the service name. Run bindercli service list on the device, or check servicemanager/service_names_gen.go for well-known constants.

2. Find the generated proxy. Browse the android/ and com/ packages on pkg.go.dev or use grep:

# Find the proxy for a known AIDL interface
grep -r 'DescriptorI.*= "android.os.IVibratorService"' android/

3. Connect and call methods:

    svc, err := sm.GetService(ctx, servicemanager.VibratorService)
    if err != nil {
        log.Fatal(err)
    }
    proxy := genOs.NewVibratorServiceProxy(svc)
    result, err := proxy.SomeMethod(ctx, args...)

4. For HAL services (hardware abstraction layers), the service name is the AIDL descriptor plus /default:

    svc, err := sm.GetService(ctx, servicemanager.ServiceName(health.DescriptorIHealth+"/default"))

5. For services without a generated proxy, use raw transactions (see Send a Raw Binder Transaction above).

bindercli lets you call any Android system service from the command line — no Go code needed.

Install and deploy:

GOOS=linux GOARCH=arm64 go build -o build/bindercli ./cmd/bindercli/
adb push build/bindercli /data/local/tmp/

Try it:

# List all binder services
adb shell /data/local/tmp/bindercli service list

# Check battery level
adb shell /data/local/tmp/bindercli android.hardware.health.IHealth get-health-info

# Query ActivityManager
adb shell /data/local/tmp/bindercli android.app.IActivityManager get-process-limit

# Get GPS hardware info
adb shell /data/local/tmp/bindercli android.location.ILocationManager get-gnss-hardware-model-name

Commands and Tools

	Description
tools/cmd/aidlgen	AIDL-to-Go compiler: reads search paths + AIDL files, generates Go code
tools/cmd/aospgen	Bulk generator: discovers all AIDL files in AOSP submodules, generates everything
tools/cmd/gen_e2e_smoke	Generates smoke tests exercising every proxy type in generated packages
tools/cmd/genreadme	Regenerates the package table in this README from generated packages

bindercli

bindercli is a unified command-line tool for interacting with Android Binder services and the AIDL compiler. It auto-generates subcommands for every AIDL interface in the project (1,500+ interfaces, 14,000+ methods), so you can call any Android system service method directly from the command line with typed flags.

Build and deploy:

GOOS=linux GOARCH=arm64 go build -o build/bindercli ./cmd/bindercli/
adb push build/bindercli /data/local/tmp/

Core subcommands:

Command	Description
bindercli service list	List all registered binder services with alive/dead status
bindercli service inspect <name>	Show a service's handle, descriptor, and alive status
bindercli service methods <name>	List all methods available on a service
bindercli service transact <name> <code> [hex]	Send a raw binder transaction
bindercli aidl compile [-I path] <files>	Compile .aidl files to Go
bindercli aidl parse <file>	Dump parsed AIDL AST as JSON
bindercli aidl check <files>	Validate AIDL files without generating
bindercli <descriptor> <method> [--flags]	Call any AIDL method with typed parameters

Global flags: --format json|text|auto, --binder-device, --map-size.

Examples

Note: Generated proxy commands use transaction codes compiled from the AIDL snapshot in tools/pkg/3rdparty/. If the device runs a different Android version, some proxy methods may return parse errors due to transaction code mismatches. The service subcommands and ServiceManager-level lookups work across all versions.

List and inspect services

# List all registered binder services with alive/dead status
bindercli service list

# Inspect a specific service (show handle, descriptor, alive status)
bindercli service inspect SurfaceFlinger

# List methods available on a service (from generated registry)
bindercli service methods activity

# Send a raw binder transaction (service name, transaction code, optional hex data)
bindercli service transact SurfaceFlinger 64

Query power and battery state

# Check if screen is on
bindercli android.os.IPowerManager is-interactive
# Example output: {"result":true}

# Check power save mode
bindercli android.os.IPowerManager is-power-save-mode
# Example output: {"result":false}

# Check if device is in Doze mode
bindercli android.os.IPowerManager is-device-idle-mode
# Example output: {"result":false}

# Get battery health info
bindercli android.hardware.health.IHealth get-health-info

Connect to a WiFi AP with SSID "MyNetwork" and PSK "secret123"

# Step 1: Add a new network via the supplicant
bindercli android.hardware.wifi.supplicant.ISupplicantStaIface add-network

# Step 2: Set the SSID (pass as hex-encoded bytes; "MyNetwork" = 4d794e6574776f726b)
bindercli android.hardware.wifi.supplicant.ISupplicantStaNetwork set-ssid \
  --ssid 4d794e6574776f726b

# Step 3: Set the WPA passphrase
bindercli android.hardware.wifi.supplicant.ISupplicantStaNetwork set-psk-passphrase \
  --psk secret123

# Step 4: Set key management to WPA-PSK (bit 1 = 0x02)
bindercli android.hardware.wifi.supplicant.ISupplicantStaNetwork set-key-mgmt \
  --keyMgmtMask 2

# Step 5: Enable the network to trigger connection
bindercli android.hardware.wifi.supplicant.ISupplicantStaNetwork enable \
  --noConnect false

# Disconnect from current network
bindercli android.hardware.wifi.supplicant.ISupplicantStaIface disconnect

# List saved networks
bindercli android.hardware.wifi.supplicant.ISupplicantStaIface list-networks

Take a picture from the camera

# List available camera devices
bindercli android.hardware.camera.provider.ICameraProvider get-camera-id-list

# Get camera characteristics (resolution, capabilities, etc.)
bindercli android.hardware.camera.device.ICameraDevice get-camera-characteristics

# Toggle flashlight/torch mode
bindercli android.hardware.camera.provider.ICameraProvider set-torch-mode \
  --cameraDeviceName "0" --enabled true

Note: Full camera capture requires a callback-driven session flow (open -> configure streams -> capture request -> receive frames). The individual steps are available as commands, but the session orchestration needs a script or the Go API directly.

Record from microphone

# Get active microphones on an input stream
bindercli android.hardware.audio.core.IStreamIn get-active-microphones

# Set microphone field dimension (for directional recording)
bindercli android.hardware.audio.core.IStreamIn set-microphone-field-dimension \
  --zoom 1.0

# Set microphone direction
# 0=UNSPECIFIED, 1=FRONT, 2=BACK, 3=EXTERNAL
bindercli android.hardware.audio.core.IStreamIn set-microphone-direction \
  --direction 1

Note: Actual audio capture requires opening an input stream via IModule.openInputStream() with an audio configuration, then reading PCM data from the returned stream handle. Use the Go API for the full recording flow.

Query battery, power, and thermal status

# Get current thermal status (0=none, 1=light, 2=moderate, ...)
bindercli android.os.IThermalService get-current-thermal-status
# Example output: {"result":0}

# Check if device is in power save mode
bindercli android.os.IPowerManager is-power-save-mode
# Example output: {"result":false}

# Check if device is interactive (screen on)
bindercli android.os.IPowerManager is-interactive

# Reboot the device
bindercli android.os.IPowerManager reboot \
  --confirm false --reason "cli-reboot" --wait true

Query packages and app info

# Check if a package is installed
bindercli android.content.pm.IPackageManager is-package-available \
  --packageName com.android.settings --userId 0
# Example output: {"result":true}

# Check a permission
bindercli android.content.pm.IPackageManager check-permission \
  --permName android.permission.INTERNET \
  --pkgName com.android.settings --userId 0

# Get the installer of a package
bindercli android.content.pm.IPackageManager get-installer-package-name \
  --packageName com.android.chrome

Display info

# Get display IDs
bindercli android.hardware.display.IDisplayManager get-display-ids \
  --includeDisabled false
# Example output: {"result":[0]}

Clipboard operations

# Check if clipboard has text
bindercli android.content.IClipboard has-clipboard-text \
  --callingPackage com.android.shell \
  --attributionTag "" --userId 0 --deviceId 0
# Example output: {"result":false}

Bluetooth operations

# Initialize Bluetooth HCI
bindercli android.hardware.bluetooth.IBluetoothHci initialize \
  --callback <callback_service>

# Send raw HCI command (hex bytes)
bindercli android.hardware.bluetooth.IBluetoothHci send-hci-command \
  --command 01030c00

# Close Bluetooth HCI
bindercli android.hardware.bluetooth.IBluetoothHci close

ActivityManager queries

# Check if user is a monkey (automated test)
bindercli android.app.IActivityManager is-user-a-monkey

# Get process memory limit
bindercli android.app.IActivityManager get-process-limit

# Check a permission for a process
bindercli android.app.IActivityManager check-permission \
  --permission android.permission.INTERNET --pid 1 --uid 0

# Force stop a package
bindercli android.app.IActivityManager force-stop-package \
  --packageName com.example.app --userId 0

# Check if app freezer is supported
bindercli android.app.IActivityManager is-app-freezer-supported

Telephony

# Get active phone type (0=NONE, 1=GSM, 2=CDMA)
bindercli com.android.internal.telephony.ITelephony get-active-phone-type

# Get network country ISO
bindercli com.android.internal.telephony.ITelephony get-network-country-iso-for-phone \
  --phoneId 0

Verified Devices

Commands are tested against the following devices. The runtime uses version-aware transaction code resolution (binder/versionaware) with tables for API 34, 35, and 36. "SM" = ServiceManager-level lookup, "Proxy" = generated proxy method with version-aware code resolution.

Verification matrix

Command	Type	Pixel 8a (API 36)	Emulator (API 35)
service list	SM	PASS	PASS
service inspect	SM	PASS	PASS
location get-all-providers	Proxy	PASS	PASS
location is-provider-enabled-for-user	Proxy	PASS	PASS
location get-gnss-hardware-model-name	Proxy	PASS	PASS
location get-gnss-year-of-hardware	Proxy	PASS	PASS
thermal get-current-thermal-status	Proxy	PASS	PASS
power is-power-save-mode	Proxy	PASS	PASS
power is-interactive	Proxy	PASS	PASS
pm is-package-available	Proxy	PASS	PASS
display get-display-ids	Proxy	PASS	PASS
clipboard has-clipboard-text	Proxy	PASS	PASS
am check-permission	Proxy	PASS	PASS
am is-user-a-monkey	Proxy	FLAKY*	PASS
am get-process-limit	Proxy	FLAKY*	PASS

* Some IActivityManager methods return empty replies intermittently on the Pixel 8a, likely due to the device's firmware AIDL revision having additional methods beyond the android-16.0.0_r1 snapshot. The transaction code offset may be off by 1-2 for some methods.

Architecture

The project has two major parts: a compiler that turns .aidl files into Go source code, and a runtime that implements the Binder IPC protocol for communicating with Android services.

Compiler Pipeline

The compiler transforms AIDL source files into Go code through four stages:

flowchart LR
    subgraph S1["1. Lex"]
        L1["Keywords, identifiers,<br/>operators, literals"]
    end

    subgraph S2["2. Parse"]
        P1["Document AST:<br/>interfaces, parcelables,<br/>enums, unions, constants"]
    end

    subgraph S3["3. Resolve"]
        R1["Transitive imports<br/>Type registry<br/>Circular import detection"]
    end

    subgraph S4["4. Generate"]
        G1["Go source files:<br/>proxies, structs,<br/>marshal/unmarshal"]
    end

    S1 --> S2 --> S3 --> S4

Loading

Stage 1 — Lexer (tools/pkg/parser/lexer.go): Tokenizes AIDL source into keywords (interface, parcelable, oneway, ...), identifiers, operators, and literals. Handles >> splitting for nested generics like List<List<String>>.

Stage 2 — Parser (tools/pkg/parser/parser.go): Recursive-descent parser builds a typed AST. Supports the full AIDL grammar: interfaces with methods and transaction codes, parcelables with typed fields and defaults, enums with explicit or implicit values, unions, nested types, generics (List<T>, Map<K,V>), annotations (@nullable, @Backing, @utf8InCpp), and constant expressions with arithmetic/bitwise operators.

Stage 3 — Resolver (tools/pkg/resolver/resolver.go): Given search paths (-I flags), resolves AIDL imports transitively. Converts qualified names like android.os.IServiceManager to file paths, parses each imported file, and registers all definitions in a shared TypeRegistry. Detects circular imports. Supports skip-unresolved mode for bulk AOSP processing where some imports reference unavailable files.

Stage 4 — Code Generator (tools/pkg/codegen/): Produces Go source for each AIDL definition:

AIDL Type	Generated Go Code
Interface	Go interface + proxy struct with Transact()-based methods, descriptor constant, transaction code constants
Parcelable	Go struct with MarshalParcel(*parcel.Parcel) error and UnmarshalParcel(*parcel.Parcel) error
Enum	Type alias on backing type (int32, int64, byte) + typed const block
Union	Struct with tag field + typed variant accessors

The code generator includes an import graph (tools/pkg/codegen/import_graph.go) that computes strongly-connected components (Tarjan's SCC algorithm) to detect and break import cycles between generated packages.

Binder Runtime

The runtime implements the Android Binder IPC protocol in pure Go:

flowchart TD
    subgraph APP["Your Go Application"]
        PROXY2["ActivityManagerProxy.GetProcessLimit(ctx)"]
    end

    subgraph MARSHAL["parcel"]
        M1["WriteInterfaceToken(descriptor)"]
        M2["WriteInt32 / WriteString16 / ..."]
        M3["ReadInt32 / ReadString16 / ..."]
    end

    subgraph BINDER["binder"]
        B1["IBinder.Transact(ctx, code, flags, data)"]
        B2["ReadStatus(reply) → check AIDL exceptions"]
    end

    subgraph KERNEL["kernelbinder"]
        K1["open(/dev/binder)"]
        K2["mmap(1MB read buffer)"]
        K3["ioctl(BINDER_WRITE_READ)"]
    end

    PROXY2 --> M1
    M1 --> M2
    M2 --> B1
    B1 --> K3
    K3 -->|reply| B2
    B2 --> M3
    M3 -->|typed result| PROXY2

Loading

kernelbinder.Driver: Opens /dev/binder, verifies the protocol version via ioctl, memory-maps the kernel buffer, and implements Transact() as a write-read ioctl. Handles transaction replies, error codes, and death notifications.

parcel.Parcel: 4-byte aligned, little-endian byte buffer implementing the Binder wire format. Writes/reads all AIDL primitive types (int32, int64, float, double, bool, byte, String as UTF-16), arrays, binder handles (flat_binder_object), and file descriptors.

binder.ProxyBinder: Client-side handle wrapping a kernel binder reference. Provides Transact(), IsAlive() (ping), and death notification registration (LinkToDeath/UnlinkToDeath).

servicemanager: Client for Android's ServiceManager, the registry of all system services. Implements GetService(), CheckService(), ListServices(), and AddService() as typed binder transactions.

Generated Code

For an AIDL interface like:

// android/app/IActivityManager.aidl
package android.app;

interface IActivityManager {
    int getProcessLimit();
    int checkPermission(in String permission, int pid, int uid);
    boolean isUserAMonkey();
    // ... 200+ more methods
}

The compiler generates:

package app

const DescriptorIActivityManager = "android.app.IActivityManager"

const (
    TransactionIActivityManagerGetProcessLimit  = binder.FirstCallTransaction + 51
    TransactionIActivityManagerCheckPermission  = binder.FirstCallTransaction + 8
    // ...
)

const (
    MethodIActivityManagerGetProcessLimit  = "getProcessLimit"
    MethodIActivityManagerCheckPermission  = "checkPermission"
    // ...
)

type IActivityManager interface {
    GetProcessLimit(ctx context.Context) (int32, error)
    CheckPermission(ctx context.Context, permission string, pid int32, uid int32) (int32, error)
    IsUserAMonkey(ctx context.Context) (bool, error)
    // ...
}

type ActivityManagerProxy struct {
    Remote binder.IBinder
}

func NewActivityManagerProxy(remote binder.IBinder) *ActivityManagerProxy {
    return &ActivityManagerProxy{Remote: remote}
}

func (p *ActivityManagerProxy) GetProcessLimit(ctx context.Context) (int32, error) {
    var _result int32
    _data := parcel.New()
    defer _data.Recycle()
    _data.WriteInterfaceToken(DescriptorIActivityManager)

    _code, _err := p.Remote.ResolveCode(ctx, DescriptorIActivityManager, MethodIActivityManagerGetProcessLimit)
    if _err != nil {
        return _result, fmt.Errorf("resolving %s.%s: %w", DescriptorIActivityManager, MethodIActivityManagerGetProcessLimit, _err)
    }

    _reply, _err := p.Remote.Transact(ctx, _code, 0, _data)
    if _err != nil {
        return _result, _err
    }
    defer _reply.Recycle()

    if _err = binder.ReadStatus(_reply); _err != nil {
        return _result, _err
    }

    _result, _err = _reply.ReadInt32()
    if _err != nil {
        return _result, _err
    }
    return _result, nil
}

Code Generation

From Individual AIDL Files

go run ./tools/cmd/aidlgen -I path/to/search/root -output . file1.aidl file2.aidl

From AOSP (Bulk Generation)

With the AOSP submodules in tools/pkg/3rdparty/:

git submodule update --init --depth 1
go run ./tools/cmd/aospgen -3rdparty tools/pkg/3rdparty -output . -smoke-tests

This discovers all AIDL files across frameworks-base, frameworks-native, hardware-interfaces, and system-hardware-interfaces, infers search roots from package declarations, and generates Go proxies for all AOSP services. The current AOSP snapshot produces 5,097 Go files across 399 packages.

Transaction Code Resolution

Each binder method has a numeric transaction code that can differ between Android versions. The generated proxies call ResolveCode() at runtime to get the correct code for the device, using a three-layer detection strategy:

1. DEX bytecode extraction (primary) — scans /system/framework/*.jar, parses DEX bytecode, and reads TRANSACTION_* constants from $Stub classes. This gives definitive codes for the exact firmware running on the device. This method is expected to work on all Android devices. If it fails on your platform, please open an issue.

2. Compiled version tables + ELF filtering (fallback) — pre-compiled tables from multiple AOSP revision tags, narrowed by API level (from ELF .note.android.ident) and exported symbols in libbinder.so.

3. Live transaction probing (last resort) — sends a test transaction (isUserAMonkey() on ActivityManager) with each candidate code and picks the one that returns a valid response.

Methods 2 and 3 exist only for extra reliability in edge cases (e.g. no read access to /system/framework/). The genversions tool builds the version tables by checking out AOSP revision tags and recording method→code mappings.

Testing and Verification

The project is verified at four levels:

1. Unit Tests

The compiler packages (parser, codegen, resolver, binder, parcel, typesys) and tools/pkg/testutil have unit tests that run without any Android device or special environment:

go test ./tools/pkg/... ./binder/ ./parcel/

These test:

• Parser correctness: Lexing/parsing of all AIDL constructs against testdata fixtures (interfaces, parcelables, enums, unions, generics, constants, annotations)
• Code generation: Each generator (GenerateInterface, GenerateParcelable, GenerateEnum, GenerateUnion) is tested by parsing AIDL input, generating Go, and verifying the output is valid gofmt-compliant Go source that contains expected identifiers (descriptors, transaction codes, type names, method signatures)
• Import cycle detection: Verifies the SCC algorithm correctly identifies and breaks cross-package import cycles
• Marshal/unmarshal naming: Maps from AIDL types to parcel read/write expressions
• Parcel serialization: Round-trip encoding/decoding of all primitive types
• Binder status: Exception code marshaling

2. AOSP Codegen Test

Tests that code generation succeeds for the entire AOSP AIDL surface (requires tools/pkg/3rdparty/ submodules):

go test -tags aosp_codegen -v -run TestCodegenAllAOSP ./tools/pkg/codegen/

Walks all ~11,000 AIDL files, parses each, generates Go code, and verifies the output parses as valid Go. Reports per-file success/failure statistics.

3. Generated Smoke Tests

Auto-generated tests that instantiate every proxy type with a mock binder and call every method with zero-value arguments:

go run ./tools/gen_e2e_smoke
go test -tags e2e ./tests/e2e/...  # requires /dev/binder OR mock mode

4. End-to-End Tests on Android

Full integration tests that open /dev/binder and transact with real Android system services:

# Run on Android device or emulator
go test -tags e2e -v ./tests/e2e/...

These verify:

• ServiceManager: ListServices, GetService, CheckService, service handle aliveness
• Typed transactions: Call ActivityManager.GetProcessLimit(), SurfaceFlinger.GetPhysicalDisplayIds(), etc. and validate returned types
• Exception handling: AIDL security exceptions, status codes
• Parcelable round-trip: Real service data deserialized through generated UnmarshalParcel
• Concurrency: Multiple goroutines with isolated binder drivers
• Death notifications: Registration/unregistration lifecycle
• Oneway transactions: Fire-and-forget calls
• Error handling: Invalid handles, dead processes

CI

Unit tests run automatically on every push and pull request via GitHub Actions. E2E tests require an Android device and must be run manually.

A weekly workflow checks for new AOSP revision tags, regenerates version tables and proxy code, and opens a PR automatically if anything changed.

Interoperability

gadb — Pure Go ADB for CI/CD

The interop/gadb/runner/ package provides pure-Go ADB device control without requiring the adb binary. Discover devices, push binaries, and run commands programmatically:

dr, _ := runner.NewDeviceRunner("SERIAL")
dr.PushBinary(ctx, "build/mybinary", "/data/local/tmp/mybinary")
output, _ := dr.Run(ctx, "/data/local/tmp/mybinary", "--flag")

For remote binder access from a host machine, interop/gadb/proxy/ sets up a forwarded session:

sess, _ := proxy.NewSession(ctx, "SERIAL")
defer sess.Close(ctx)
sm := servicemanager.New(sess.Transport())
// Use sm as if running on-device

gomobile — Android AAR

interop/gomobile/client/ wraps binder calls in a Java-friendly API via gomobile. Build the AAR:

gomobile bind -target android -o binder.aar ./interop/gomobile/client/

Available methods: GetPowerStatus(), GetDisplayInfo(), GetLastLocation(), GetDeviceInfo().

See the example app at examples/gomobile/.
