following picture is my systrace output, there is only one row. Comparing the html with some sample file, it seems in my file, there is no lines like
SurfaceFlinger-220 [001] 227112.684875: 0: B|129|onMessageReceived\n\
SurfaceFlinger-220 [001] 227112.684906: 0: B|129|handleMessageInvalidate\n\
SurfaceFlinger-220 [001] 227112.684906: 0: B|129|latchBuffer\n\
SurfaceFlinger-220 [001] 227112.684906: 0: E\n\
Is that the reason? How to solve it? I'm using mips android 4.4.2.
