<strong>Logging Trace Files</strong>

Debug can create log files that give details about an application, such as a call stack and start/stop times for any running methods. See Inspect Trace Logs with Traceview for information about reading trace files. To start logging trace files, call one of the startMethodTracing() methods. To stop tracing, call #stopMethodTracing().
