Android：adb logcat -c似乎没有刷新日志

Question

我的理解是 adb logcat -c 将完全刷新日志缓冲区。  在我启动应用程序之前，我执行 adb logcat -c 。  启动应用程序后，我这样做：

D/WeatherServiceSync( 1932): onCreate() - service created anew
D/WeatherServiceSync( 1932): onBind() - client has invoked bindService()
D/WeatherServiceSync( 1932): onUnbind() - client has invoked unbindService()
D/WeatherServiceSync( 1932): onDestroy() - service is being shut down
D/WeatherServiceSync( 1932): onCreate() - service created anew
D/WeatherServiceSync( 1932): onBind() - client has invoked bindService()
D/WeatherServiceSync( 1932): onUnbind() - client has invoked unbindService()
D/WeatherServiceSync( 1932): onDestroy() - service is being shut down

但是，日志似乎每次都会附加，如下所示

{{1}}

如您所见，onCreate到onDestroy的行集正在被复制。

我可以做些什么来刷新日志缓冲区吗？
