android - Android M 上配置文件 GPU 条的颜色

Question

当将配置文件 GPU 渲染开发人员功能设置为“在屏幕上显示为条形”时，我曾经在 Android Lollipop 上看到带有蓝色、紫色、红色和橙色的条形，如所述here .

但在 Android Marshmallow 上，这些条由七种不同的颜色组成:深绿色、中绿色、浅绿色、蓝色、浅蓝色、红色和橙色。

我没能在 Android Developers 上找到与这些颜色相关的任何信息。那么这些新颜色意味着什么？

不幸的是，目前还没有官方文档，但在 this 中Google+ 帖子 一群 Google 员工推荐了一篇博客文章，“写得非常好并详细说明了变化”。

In Marshmallow, more colors were added to indicate more steps, such as Measure/Layout, input handling and others:

EDIT 09/29/2015: John Reck, a framework engineer in Google, has added this information about some of the new colors:

The exact definition of “animation” is everything that’s registered with Choreographer as CALLBACK_ANIMATION. This includes Choreographer#postFrameCallback and View#postOnAnimation which are what’s used by view.animate(), ObjectAnimator, Transitions, etc… And yup, it’s the same thing systrace labels as “animation”.

“misc” is the delay between the vsync’s timestamp and the current timestamp when it was received. If you’ve ever seen logs from Choreographer about “Missed vsync by blabla ms skipping blabla frames”, that now shows up as “misc”. This is the difference between INTENDED_VSYNC and VSYNC in the framestats dump (https://developer.android.com/preview/testing/performance.html#timing-info)
