Don't process UEvents in Dalvik unless they match a pattern. On some devices, vsync is delivered from the kernel to userspace over a netlink socket via UEvent. The result is that a thread wakes up, reads a message, creates a new String then searches it for matches against a pattern on every single frame. Reduce the overhead by performing the initial pattern matching in native code. Bug: 7326329 Change-Id: Icb22db1c38330694207bec1153840e0c06f502d6
