我对android和java很陌生，所以要温柔:)我正在尝试通过bloototh连接两部手机。我通过创建 serversocket 让两部手机都监听来电，然后从一部手机初始化连接（作为客户端）。有趣的是，当我尝试让我的 LG（android 版本 2.3.4）连接 HTC（android 2.2.1）时一切正常，但是当我尝试让 HTC 手机作为客户端连接时，我没有得到任何结果。调试器显示 HTC 在 mmSocket.connect() 处失败；并执行 catch (IOException connectException)。我的代码基本上是从 android 蓝牙教程中复制/粘贴的。有什么建议为什么手机的行为会有所不同？连接螺纹：
private class ConnectThread extends Thread {
private final BluetoothSocket mmSocket;
private final BluetoothDevice mmDevice;
public ConnectThread(BluetoothDevice device) {
// Use a temporary object that is later assigned to mmSocket,
// because mmSocket is final
BluetoothSocket tmp = null;
mmDevice = device;
// Get a BluetoothSocket to connect with the given BluetoothDevice
try {
// MY_UUID is the app's UUID string, also used by the server code
tmp = device.createRfcommSocketToServiceRecord(MY_UUID);
} catch (IOException e) { }
mmSocket = tmp;
}
public void run() {
// Cancel discovery because it will slow down the connection
BtAdapter.cancelDiscovery();
try {
// Connect the device through the socket. This will block
// until it succeeds or throws an exception
mmSocket.connect(); **HTC phones fails here and goes to CATCH block**
// make info message
Message msg = mainHandler.obtainMessage();
Bundle bundle = new Bundle();
String btnTxt = "Connected";
bundle.putString("myKey", btnTxt);
msg.setData(bundle);
mainHandler.sendMessage(msg);
} catch (IOException connectException) {
// Unable to connect; close the socket and get out
try {
mmSocket.close();
} catch (IOException closeException) { }
return;
}
// Do work to manage the connection (in a separate thread)
ConnectedThread conThread = new ConnectedThread(mmSocket);
conThread.start();
}
/** Will cancel an in-progress connection, and close the socket */
public void cancel() {
try {
mmSocket.close();
} catch (IOException e) { }
}
}
