-LooperProfiler is a simple tool to convert and display looper traces.
-7/15/2011
-
-Note: LooperProfiler is a crude tool and needs more work.
-
-Looper traces are generated by invoking ViewDebug.startLooperProfiling()
-and ViewDebug.stopLooperProfiling().
-
-After profiling the file must be pulled from the device using adb pull.
-
-To use this tool, compile the single .java file and run:
-java LooperTraceToTraceView myLooperTracesFile looperTraceViewFile
-
-The run traceview looperTraceViewFile
