2.7.9版本开启surfaceview,设置开启adb shell dumpsys gfxinfo,卡顿jank值数据很大 #237
Comments
1、开启了surfaceview就不会用gfxinfo,这是两种不同的计算方式,gfxinfo数据其实是有一定延迟不太准确,不太建议用 |
一直用的一样场景跟时间。那还是建议关闭gfxinfo,用页面的surfaceview是吧 |
当然用surfaceview啊,工具就是默认用它的。基本适配大部分类型的app。还有渲染页面每帧如果超过16.6ms就会记一次jank,这个基本肉眼看不出来卡顿的,而且有时候相同时间内你有可能没法保证这个过程渲染过多少帧。这个值就大概对比一下就好。 |
