ตั้งแต่ปี 2026 เป็นต้นไป เราจะเผยแพร่ซอร์สโค้ดไปยัง AOSP ในไตรมาสที่ 2 และ 4 เพื่อให้สอดคล้องกับโมเดลการพัฒนาแบบ Trunk Stable และรับประกันความเสถียรของแพลตฟอร์มสำหรับระบบนิเวศ หากต้องการสร้างและมีส่วนร่วมใน AOSP ให้ใช้ android-latest-release android-latest-release สาขา Manifest จะอ้างอิงถึงรุ่นล่าสุดที่พุชไปยัง AOSP เสมอ ดูข้อมูลเพิ่มเติมได้ที่การเปลี่ยนแปลงใน AOSP

Known direct subclasses

AtraceRunMetricCollector, BluetoothHciSnoopLogCollector, FilePullerLogCollector, PerfettoFilePullerCollector, PerfettoPullerMetricCollector, ShowmapPullerMetricCollector

AtraceRunMetricCollector	Collects the traces from all the test directory under the given directory from the test device, log the test directory and post process the trace files under the test directory and aggregate the metrics.
BluetoothHciSnoopLogCollector	Collector to enable Bluetooth HCI snoop logging on the DUT and to collect the log for each test.
FilePullerLogCollector	Logger of the file reported by the device-side.
PerfettoFilePullerCollector	A collector which pulls perfetto trace files from the device, optionally compresses them, and adds them to the test logs.
PerfettoPullerMetricCollector	This class is deprecated. Use `PerfettoFilePullerCollector` and `ERROR(/PerfettoTracePostProcessor)` instead.
ShowmapPullerMetricCollector	Base implementation of `FilePullerDeviceMetricCollector` that allows pulling the showmap files from the device and collect the metrics from it.

A BaseDeviceMetricCollector that listen for metrics key coming from the device and pull them as a file from the device. Can be extended for extra-processing of the file.
