Question

我想从服务器连接到客户端的设备。在我的应用程序中，我使用的是AcceptThread类：

private class AcceptThread extends Thread {
    private final BluetoothServerSocket mmServerSocket;

    public AcceptThread() {
            BluetoothServerSocket tmp = null;

        try {                
            tmp = mBluetoothAdapter.listenUsingRfcommWithServiceRecord(NAME, MY_UUID);
        } catch (IOException e) {
            Log.e(TAG, "Socket's listen() method failed", e);
        }
        mmServerSocket = tmp;            
    }

    public void run() {           
        BluetoothSocket socket = null;

        while (true) {               
            try {                    
                socket = mmServerSocket.accept();                    
            } catch (IOException e) {                   
                Log.e(TAG, "Socket's accept() method failed", e);
                break;
            }                

            if (socket != null) {
                manageMyConnectedSocket(socket);
                try {
                    mmServerSocket.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
                break;
            }
        }
    }
}

此代码适用于三星Galaxy J3。但在三星Galaxy S6和联想Tab3 10上，应用程序停止在线 socket = mmServerSocket.accept（）; 在Lenovo选项卡上，我收到以下错误：

Socket's accept() method failed
java.io.IOException: Try again

at android.bluetooth.BluetoothSocket.accept(BluetoothSocket.java:463)
at android.bluetooth.BluetoothServerSocket.accept(BluetoothServerSocket.java:158)

三星手机都有Android 7.0。

什么可以在三星S6阻止接受蓝牙插座？

BluetoothServerSocket在某些设备上不接受Bluetoothsocket
