# 开发指南
## 性能追踪
使用 `scripts/profile.sh` 一键抓取 Perfetto trace、帧统计和内存快照。
```bash
# 默认抓取 8 秒
./scripts/profile.sh
# 抓取 15 秒
./scripts/profile.sh 15
# 应用已在运行时,不自动启动
./scripts/profile.sh --no-launch
```
输出文件保存在 `logs/` 目录:
| 文件 | 说明 |
| ------------------------ | ----------------------------------------------- |
| `trace_*.perfetto-trace` | Perfetto trace在 https://ui.perfetto.dev 打开 |
| `framestats_*.txt` | GPU 帧统计 |
| `meminfo_*.txt` | 内存快照 |
| `report_*.md` | 追踪报告摘要 |
trace 中包含自定义标记:
- `MonthView:Compose` — 月视图重组
- `CalendarPagerArea` — 日历分页器区域
- `CalendarPager:Page:*` — 月视图单页重组
- `CalendarMonthPage:*` — 月页面数据计算(含折叠动画准备)
- `WeekPager:Page` — 周视图单页重组
- `YearView:Compose` — 年视图重组
- `YearGridView:*` — 年视图网格组合(首帧耗时关键指标)
- `generateMiniMonthDays:*` — 月份网格计算
- `MonthView→YearView` / `YearView→MonthView` — 视图切换
- `YearView:SelectMonth` — 年视图选月
- `getMonthDays:*` — ViewModel 月份网格计算
- `VM:collapseProgress:*` — 折叠动画拖拽onDrag/onDragEnd/onExpandDrag/onExpandDragEnd
## Baseline Profile
```bash
# 编译 Android debug APK
./gradlew :app:assembleDebug
# 安装到设备
./gradlew :app:installDebug
# 编译 release APK含 Baseline Profiles
./gradlew :app:assembleRelease
./gradlew :app:installBenchmark
```
Baseline Profile 自动生成器。
运行方式(一键生成 + 自动复制到 :core
```
./gradlew :macrobenchmark:updateBaselineProfile
```
仅运行基准测试(不自动复制):
```
./gradlew :macrobenchmark:connectedBenchmarkAndroidTest
```
手动复制路径:
`macrobenchmark/build/outputs/connected_android_test_additional_output/`
