原理
Android perfetto memory分析工具和malloc_debug原理类似。
- 基于malloc/free函数族的 caller hook。
- 调用栈运行时聚合，并以每个调用栈为单位进行统计。
- 输出内存信息，申请次数，累计大小
- 支持native进程和Android runtime(APP进程)
- 自适应jemalloc和scudo
malloc_debug原理可以参考以下链接：
https://android.googlesource.com/platform/bionic/+/master/libc/malloc_debug/README.md

export BUILD_TARGET_IS=productsource build/envsetup.shlunch miproduct_zeus_cn-userdebugmake heapprofd -j5make完之后会在out/target/product/missi/system/bin目录下生成heapprofd模块push heapprofd
adb push heapprofd /system/bin
adb shell chmod 777 /system/bin/heapprofd工具使用
关键点：
python3 tools/heap_profile -n vendor.qti.camera.provider@2.7-service_64 --all-heaps -i $sampling_interval -o heap_trace_$DATE关于参数：-i ,默认4KB，采样间隔，如果设置比较大，会出现申请小的trace不会体现，如果设置比较小会出现严重的性能问题，关键看需求。
ps : trace中参数含义 ---- From : Perfetto.Docs.Case Studies.Debugging Memory usage
The tabs that are available are
- space: how many bytes were allocated but not freed at this callstack the moment the dump was created.
- alloc_space: how many bytes were allocated (including ones freed at the moment of the dump) at this callstack
- objects: how many allocations without matching frees were sampled at this callstack.
- alloc_objects: how many allocations (including ones with matching frees) were sampled at this callstack.
pb文件获取
pb文件有两种方式获取：
获取方式一：抓取trace后，文件夹会生成.pb文件
获取方式二：点击trace网页中的Download profile，即可自动生成*.pb
打开*.pb文件
https://www.speedscope.app （将pb文件上传到网页中）
trace文件
通过这个网站打开：https://perfetto.dev/
可以显示每个函数的heap内存占用，这里截个图如下所示：
提高系统CPU性能
因为运行perfetto会导致一定的性能开销，导致手机会比较卡顿，下面命令可以提高CPU性能。
adb shell "echo performance > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor"
adb shell "echo performance > /sys/devices/system/cpu/cpufreq/policy4/scaling_governor"
adb shell "echo performance > /sys/devices/system/cpu/cpufreq/policy6/scaling_governor"
adb shell "echo performance > /sys/devices/system/cpu/cpufreq/policy7/scaling_governor"
手动dump当前heap内存命令：
adb shell killall -USR1 heapprofd
trace右上角dump的pd文件解析网站：
https://www.speedscope.app
拆解特定函数内存占用
环境配置
adb push perfetto /system/bin
adb shell chmod 777 /system/bin/perfetto
adb push heapprofd /system/bin
adb shell chmod 777 /system/bin/heapprofd
工具使用
-f 参数后面设置过滤的函数名，若有多个函数，用，分隔
