android - BluetoothSocket.isConnected 问题

Question

我已经创建了一个 Android 应用程序，如果我的 Android 有一个蓝牙连接到我的电脑并且我关闭了我的电脑，isConnected 仍然返回 true。有人知道这是否可以修复吗？

不知道有没有蓝牙心跳

Answer 1

试试这个。

    IntentFilter connectivityFilter = new IntentFilter();
    connectivityFilter.addAction(BluetoothDevice.ACTION_ACL_CONNECTED);
    connectivityFilter.addAction(BluetoothDevice.ACTION_ACL_DISCONNECTED);
    registerReceiver(bluetoothModeCheckingReceiver, connectivityFilter);



 private final BroadcastReceiver bluetoothModeCheckingReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (action.equals(BluetoothDevice.ACTION_ACL_DISCONNECTED)) {
            // to do
        } else if (action.equals(BluetoothDevice.ACTION_ACL_CONNECTED)) {
           //  to do
        }
    }
};
