Java Android TCP客户端连接冻结iBeacon范围

我有一个Android TCP客户端，它通过Aysnctask与服务器通信，以避免冻结UI。我还对iBeacon进行了测距，并尝试将iBeacon信息发送到服务器。但是，当我按下connect按钮时，iBeacon范围冻结，这意味着DidRangeBeanConsistinRegion收集iBeacons，Region方法不再工作。如果您发现任何可能导致此问题的因素，请告诉我。我的异步任务是否意外影响UI？以下是相关代码：

单击“连接”按钮：

            case R.id.connect: 
            if(!connect.isChecked()) {
                //if(mTcpClient.isConnected) {
                    mTcpClient.sendMessage("close");
                    mTcpClient.stopClient();
                //}
            }
            if(connect.isChecked()) {
                new ConnectTask().execute("");
                sendMsg.setEnabled(true);
                msgBox.setEnabled(true);
                sendInfo.setEnabled(true);
                text.setText("Send a message...");
            }
            break;

用于服务器通信的异步任务：

    //************************************************************************************
// ASYNCTASK: Creates connection to server
//************************************************************************************
public class ConnectTask extends AsyncTask<String,String,TcpClient> {
    @Override
    protected TcpClient doInBackground(String... message) {
        //we create a TCPClient object
        mTcpClient = new TcpClient(new TcpClient.OnMessageReceived() {
            @Override
            //here the messageReceived method is implemented
            public void messageReceived(String message) {
                //this method calls the onProgressUpdate

                publishProgress(message);
            }
        });
        ip = sharedPref.getString("ip_address", "");
        port = sharedPref.getString("port", "");
        mTcpClient.run(ip, port);
        return null;
    }

    //Provides Progress Updates (when message is received from server)
    @Override
    protected void onProgressUpdate(String... values) {
        super.onProgressUpdate(values);
        //here we can receive values when called from publishProgress
        //this function allows you to update the UI without hanging or any other problems
        //when you call your GUI object on it's .notifyDataSetChanged(), it will refresh automatically      
        text.setText("You got a message!!");
        text.setText("Message: ");
        toast = Toast.makeText(getBaseContext(), "Received Message: See Message Box", Toast.LENGTH_LONG);
        toast.show();
        try{ JSONObject jsonReceived = new JSONObject(values[0]);

            x = Integer.parseInt(jsonReceived.getString("x"));
            y = Integer.parseInt(jsonReceived.getString("y"));
            Log.i("TESTING", "x: " + x + "y: " + y);

        } catch (Exception je) {}

        message.setText(Arrays.toString(values));
        plotPoints(x, y);
    }

}  

}

如果你有任何建议，请告诉我。谢谢

DidRangeBeanConsistencyRegionCollection iBeacons，Region还被调用吗？在方法中添加调试行以查找。您是使用TCP over mobile还是wifi？2.4 Ghz wifi和BLE具有类似的频率，例如Nexus 4上的wifi和BLE无线电之间存在已知问题。您的信标代码是否也使用异步任务？在最近的Android版本中，所有异步任务都在一个线程上一个接一个地运行，因此一个长线程可能会阻止其他线程。如果您想要以前版本的并行行为，您可以指定在执行它们时它们应该在线程池上运行。
