Question

我遇到一些问题，需要连续运行多个扫描。以下是我处理行动的方式：

if(BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)){
            Log.w("Bluetooth", "SCAN STOPPED EVENT");
            try{
                mBluetoothAdapter.startDiscovery();
            }catch(Exception ex){
                Log.w("Bluetooth", ""+ex);
            }
        }

扫描完成后，我得到以下日志输出。在此示例中，扫描发现了5个设备。

(main) [1,17346] SCAN STOPPED EVENT
(524): mDeviceProperties size is 5
(524): mCache size is 5

(524): Deleting object66:33:44:00:33:88
(524): mDeviceProperties size is 0
(524): mCache size is 0

显然会经历某种过程，它会删除所有缓存的设备，但它永远不会再次启动扫描..任何人对此都有任何建议吗？
