[bug]android monkey命令在Android N和Android O上的一点差异发现

时间:2024-01-07 21:02:50

最近再调试这个统计FPS的代码,发现代码在android N上可以正常运行,但在android O上却运行不了,拼了命的报错,给出的提示就是 ZeroDivisionError: division by zero,看这错误很明显就是除数不能为0,理论上来说这问题也比较好定位就一步一步找了,排查代码后发现获取除数这个值的逻辑有问题,重新把逻辑修改后获取到正确的值后,重新运行命令跑的时候有时候会有值,有时候还是继续报这个除数不能为零,再重新查看这个除数的来源,是当屏幕有刷新时才能获取到该值,再查看让屏幕刷新的代码,发现是通过monkey的命令来模拟拖动屏幕操作,但在实际测试过程中屏幕根本就没有动,接下来就看Monkey的命令 :adb shell monkey -f /sdcard/monkeyTest_UD.txt 10,发现是从sd卡中获取一个monkey脚本来运行的,打开monkey脚本后,看看格式也没有啥问题。如下

type = user
count = 10
speed = 1.0
start data >> Drag(300.0, 307.2, 300.0, 819.2,122.8)
Drag(300.0, 307.2, 300.0, 819.2,122.8)
Drag(300.0, 819.2, 300.0, 307.2,122.8)
Drag(300.0, 819.2, 300.0, 307.2,122.8)

  

给出monkey命令中drag的命令语法:

Drag(xStart,yStart,xEnd,yEnd,stepCount)

D:\WorkSpace3\Performance\>python3 FPStest.py -o UD -c 10
通过gfxinfo取值, 测试开始... bash arg: -f
bash arg: /sdcard/monkeyTest_UD.txt
bash arg: 10
args: [-f, /sdcard/monkeyTest_UD.txt, 10]
arg: "-f"
arg: "/sdcard/monkeyTest_UD.txt"
arg: "10"
data="/sdcard/monkeyTest_UD.txt"

找到生成monkey脚本的代码,把它调整为整型并保存重新全跑一次所有代码,结果正常生成。
