安卓专项 fps获取
作者：互联网
场景
需要实时获取到设备当前fps情况
实现
使用命令：adb shell dumpsys gfxinfo packageName framestats
百度得知在Android 6.0以后为gfxinfo 提供了一个新的参数framestats，其作用可以从最近的帧中提供非常详细的帧信息，以便您可以更准确地跟踪和调试问题。
是不是可以理解成，获取的是最近的帧数
当输出这段命令后得出很多信息

我们只需要拿到---PROFILEDATA--- 之间的值就可以了
文档参考：
https://wizzie.top/Blog/2020/03/31/2020/200330_android_getFPS/
https://blog.csdn.net/cxq234843654/article/details/79914535
一行数据为一帧，所需要消耗的时间，单位是纳秒
我们知道，一秒是60帧是最佳，一帧不得超过16.67，如果超过记为 janky 计数加1
一帧所消耗的时间 = FrameCompleted - IntendedVsync
刚执行获取到大概是120帧
fps = 总帧数/总帧数+jank数量 * 60 就得出一秒的帧率
在每次获取数据后，最好需要清理下
adb shell dumpsys gfxinfo packageName reset
问题
1、在命令中，可能获取道多个PROFILEDATA ，不知道获取哪个之间的数据
这里就需要获取到当前的activity，来进行判断，获取当前activity的值
def fps_data_list():
info = adb.call("adb shell dumpsys gfxinfo {} framestats ".format(package))
start_data = False # 控制获取数据
activity = False # 控制获取当前activity
data_list = []
activit = adb.get_activity()
for i in info:
if str(activit) in str(i).strip():
activity = True
if activity:
if "PROFILEDATA" in i:
if start_data:
start_data = False
activity = False
break
else:
start_data = True
if start_data:
data_list.append(i)
total = len(data_list)
logger.info(total)
if total<5:
return 0
data_list = data_list[2:]
jank = 0
for j in data_list:
data_list = j.split(",")
times = round((int(data_list[13])-int(data_list[1]))/1000000,2)
if times>16.67:
jank+=1
fps = int(total/(total+jank)*60)
adb.call("adb shell dumpsys gfxinfo {} reset ".format(package))
return fps
