Android api told scanWifi maybe failed , and this time will return old scan result , So does this util have some way to judgment scan success or fail? : )?

PS：

• boolean scanStartSuccess = wifiManager.startScan();// scanStartSuccess
• boolean scanSuccess = intent.getBooleanExtra( WifiManager.EXTRA_RESULTS_UPDATED, false);
