# 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/`
|
||
|
||
测试覆盖全部用户交互路径,实现全量 AOT:
|
||
|
||
1. 冷启动 → 首帧渲染
|
||
2. FAB 展开 → 年视图 → 月视图
|
||
3. 日期选择 → 周视图折叠/展开
|
||
4. 关于页 → 开源许可页
|
||
5. 返回主界面
|
||
|
||
## 模拟器
|
||
|
||
```
|
||
emulator -avd Pixel_10 \
|
||
-no-snapshot \
|
||
-no-boot-anim \
|
||
-gpu host \
|
||
-accel on \
|
||
-cores 4 \
|
||
-memory 4096 \
|
||
-partition-size 2048
|
