1:如何计算FPS信息?
标准的FPS 是 1s 60 帧,也就是16.67ms一帧渲染完成,用户不会觉得卡顿。但是大部分应用是不需要1s内绘制60帧,我们需要根据丢帧率去计算fps,如果1s内应用只需要绘制30帧,但每帧的时间是不超过16.67ms,那么它的fps也是60。
当一帧渲染的时间大于16.67ms,按照垂直同步机制,该帧就已经渲染超时,那么,如果它正好是16.67的整数倍,比如66.68,则它花费了4个垂直同步脉冲,减去本身需要一个,则超时3个;如果它不是16.67的整数倍,比如67,那么它花费的垂直同步脉冲应向上取整,即5个,减去本身需要一个,即超时4个,可直接算向下取整
最后的计算方法思路:
执行一次命令,总共收集到了m帧(理想情况下m=128),但是这m帧里面有些帧渲染超过了16.67毫秒,算一次jank,一旦jank,
需要用掉额外的垂直同步脉冲。其他的就算没有超过16.67,也按一个脉冲时间来算(理想情况下,一个脉冲就可以渲染完一帧)
所以FPS的算法可以变为:
m / (m + 额外的垂直同步脉冲) * 60
2:如何获取FPS信息?
Android性能测试之fps获取
安卓8.0之前使用dumpsys SurfaceFlinger 获取FPS信息详解(必看)
adb shell dumpsys SurfaceFlinger –latency <window_activity>
安卓9.0之后使用dumpsys gfxinfo framestats 获取FPS信息详解(必看)
adb shell dumpsys gfxinfo < PACKAGE_NAME > framestats
两种都是获取指定窗口的详细显示信息,需要了解每一列参数的详细信息
以9.0之后使用dumpsys gfxinfo 获取信息为例:
每一帧的时间就是 FRAME_COMPLETED – INTENDED_VSYNC ,时间是以ns为单位
3:python实现 fps实时获取和计算
使用adb shell dumpsys gfxinfo 获取fps信息
由于是根据包名获取每一帧的详细信息,且最多只能获取128帧,所以最理想的状态就是2s内手机绘制了120帧,但大部分应用2s内是不会绘制120帧的,所以根据实际项目需要,我们需要设置不同的时间间隔去获取fps,此处我们使用2s间隔获取一次fps数据,相同时间内,绘制的帧越多,则fps越准确。
self.frequency = 2 取样频率 就是每间隔2秒获取一次fps信息
sn是设备id
_collector_thread 是用来获取fps信息的线程
_calculator_thread 是用来计算fps的线程
定义大于16.67ms为丢帧 jank
定义大于166.7ms为卡顿 caton
1:在开始获取fps信息之前,我们先进行获取当前活动窗口,get_focus_window
adb shell dumpsys activity | findstr mResume(适用于安卓9.0之后的,安卓8.0之前可使用adb shell dumpsys activity | findstr “mFocusedActivity”)
C:Usersysfa>adb shell dumpsys activity | findstr mResumemResumedActivity: ActivityRecord{db71ee8 u0 com.android.settings/.SubSettings t1572}
com.android.settings/.SubSettings 这个则是当前手机上活动的窗口名(包名省略为.)
注意! 部分三方应用的窗口会把包名全部显示,例如com.eg.android.AlipayGphone/com.alipay.mobile.security.login.ui.RecommandAlipayUserLoginActivity
C:Usersysfa>adb shell dumpsys activity | findstr mResumemResumedActivity: ActivityRecord{e84c958 u0 com.eg.android.AlipayGphone/com.alipay.mobile.security.login.ui.RecommandAlipayUserLoginActivity t1576}
拿到窗口名,我们可以提取出包名+窗口名的信息
因为使用shell dumpsys gfxinfo +包名+framestats 获取的这个进程的最近128帧的的详细信息,可能包含多个窗口(也可能包含重复帧),而信息中的窗口名是全名,没有.省略包名,所以我们需要自己拼出完整的窗口名
如将com.android.settings/.SubSettings 改成com.android.settings/com.android.settings.SubSettings
**
2:在开始获取fps信息之前,我们先进行清除当前窗口fps数据
"adb shell dumpsys gfxinfo " + package_name + " reset"
3:使用shell dumpsys gfxinfo +包名 + framestats 获取的这个进程的最近128帧的的详细信息,可能包含多个窗口(也可能包含重复帧,也可能没有128帧)
例如下面则是有两个窗口
C:Usersysfa>adb shell dumpsys gfxinfo com.android.settings framestats

例如下面则是有两个窗口
Window: com.android.settings/com.android.settings.SubSettings(窗口一)
Window: com.android.settings/com.android.settings.Settings(窗口二)
我们需要根据上面获取的当前活动窗口(包名不能省略,如果包名省略了,需要转换为全名),去筛选出当前正在活动窗口的fps信息,也就是PROFILEDATA的中间数据
原理:根据返回的信息中含有window去定位到当前窗口,第一个—PROFILEDATA— 中的数据就是当前窗口的详细信息
详细方法看_get_fps_data

4:去除重复帧
记录当前窗口的最后一次时间(第一次取0,可能会存在一些误差,所以测试之前我们需要清除数据),遍历PROFILEDATA中IntendedVsync(每帧的起始时间)的时间大于最后一次记录的时间,这时候就不是重复帧,才进行采集数据
# 我们需要在次数去除重复帧,通过每帧的起始时间去判断是否是重复的for timestamp in each_frame_timestamps:if timestamp[0] > self.last_timestamp:timestamps.append((timestamp[1] - timestamp[0]) / 1000000)self.last_timestamp = timestamp[0]return timestamps, int(phone_time)
5:计算FPS,jank,卡顿
每帧耗时时间 time = (FRAME_COMPLETED – INTENDED_VSYNC)/1000000 (单位ms)
最终去除重复帧后,集合中有多少行就是有多少帧绘制,大于16.67ms的则是jank ,大于166.7ms则是卡顿
总共收集到了m帧(理想情况下m=128),但是这m帧里面有些帧渲染超过了16.67毫秒,算一次jank,一旦jank,
需要用掉额外的垂直同步脉冲。其他的就算没有超过16.67,也按一个脉冲时间来算(理想情况下,一个脉冲就可以渲染完一帧)
所以FPS的算法可以变为:
m / (m + 额外的垂直同步脉冲) * 60
6:python脚本实现
FpsInfo 是结构体
FpsListenserImpl 是定义的接口实现,用来调用显示和打印的,调试时可删除
功能就是每隔2s获取当前活动窗口的fps,并统计丢帧数和丢帧的耗时时间
执行结果如下
