问题：FPS 数据获取不到，一直输出是 0 ，请问需要开启什么嘛？求大佬指引~

surfaceview

试了下用 surfaceview ，但还是没有 FPS 数据。（设备：ADT-AN00、PHB110）

麻烦问题下，你那边可以了么，我的手机（PHB110）也是获取不到fps，请问怎么解决

其实还有一种情况，Android 12以后，SurfaceView引入了一个Blast，导致安卓12以上的设备，其实需要通过含有BLAST的字段的那个做匹配，这样获取到的fps数据才是正确的，也可能是我测试的是unity制作的应用。但按照我后面改的代码，其他应用我测试目前也没有问题，其他应用会走get_surfaceview而不是get_surfaceview_activity。

网上搜索到的BLAST的解释： Android S（也就是12.0）版本之前，关于应用显示方面面临几个问题：应用程序在缓冲区的提交中灵活性不足，窗口与应用绘制之间无法做到同步，多进程数据无法做到同步。BLAST 旨在解决这两个问题，同时简化 SF 中的模型。

所以可以在_get_surfaceflinger_frame_data中get_surfaceview得到的focus_window通过dumpsys SurfaceFlinger --latency xxx获取的数据不对的时候，将get_surfaceview_activity的判断中加入一个判断BLAST字符串是否存在，同时后面activity_line不做处理，就能在android 12以及以上设备得到正确的结果，这是我临时修改后，可以正确在安卓12上获取fps数据的代码，作者可以看看是否可以改动一下。这只是临时版本，也可以考虑判断设备sdk版本是否是31，然后加入相应判断即可。仅供作者参考，作者的这个项目我很佩服，谢谢。
