调研方向
从 dist/android/utils/adb.js 中的 parseAdbDevices 开始，issue 指出了用于分类 ADB 设备的 device: 名称检查。根据报告的 emulator-5554 属性验证行为，并检查 Android 设备列表测试。完成标准是：已连接的 emulator-<port> 即使设备名称为 emu64xa16k，也会列为虚拟设备，并且可以通过 --virtual 选择。
由索引模型根据 Issue 内容生成。
描述
Version: native-run 2.0.3 (latest on npm)
Platform: Linux x86_64, Android Emulator 37.1.11, AVD from the Pixel 10 profile with a 16 KB page-size system image (sdk_gphone16k_x86_64, API 37)
Description
A running emulator is classified as hardware, so --virtual cannot select it and run fails with ERR_NO_TARGET, even though adb lists the emulator as connected.
adb devices -l reports:
emulator-5554 device product:sdk_gphone16k_x86_64 model:sdk_gphone16k_x86_64 device:emu64xa16k transport_id:1
dist/android/utils/adb.js (parseAdbDevices) only treats a serial as an emulator when its device: property starts with generic:
const isGenericDevice = (properties['device'] || '').startsWith('generic');
const type = 'usb' in properties || isIP || !serial.startsWith('emulator') || !isGenericDevice ? 'hardware' : 'emulator';
Current emulator system images report device:emu64xa16k (and similar emu64* values), not generic*. The emulator therefore becomes type: 'hardware'.
Steps to reproduce
- Start an AVD whose system image reports a non-
genericdevice name, e.g. a recent Google APIs / 16 KB page-size image. native-run android --list --jsonlists it underdevices, andvirtualDevicesstays empty.native-run android --app app-debug.apk --virtualfails:
ERR_NO_TARGET: No target devices/emulators available.
The same command without --virtual installs on the emulator, because it is picked as a hardware device.
ionic cordova run android --emulator maps to --virtual, so Ionic Cordova live reload on an emulator is affected.
Expected
A serial of the form emulator-<port> that adb reports in the device state is a running emulator, whatever its device: property says. --virtual should select it.
Possible fix
Classify emulator-<port> serials as emulators without depending on the device: name, or additionally accept the emu* prefix. Alternatively, check ro.kernel.qemu / ro.boot.qemu from getprop, which getDevices already reads.
