多次在非活动类中获取上下文

我正在开发一个应用程序,其中“更新程序”不断从服务器请求数据。如果接收到新数据,数据将通过本地广播发送给活动。为此,我需要传入构造函数的当前上下文。此外,新数据被写入一个单例类(通过应用程序的运行时存储)。

问题是,我需要不断为LocalBroadcast创建新的上下文,但它在构造函数中只传递了一次。是否有人知道每次本地广播发送内容时如何获取当前上下文?

我找到了这个答案,但我总是被警告不要将上下文类放在静态字段中。( Get application context from non activity singleton class )

感谢您的阅读和每一条建议。 这是我的“更新程序”代码:

import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.support.v4.content.LocalBroadcastManager;

import java.util.Arrays;


public class ClientUpdater extends Thread {
    ClientCommunication cComm;              //this is my class which manages the Server-Client-Communication
    Intent BroadcastIntentUpdate;           //Intent for the LocalBroadcast
    Context cntxt;                          //stores the context passed in the constructor
    GlobalClass Obj1;                       //Instance of my Singleton

    public ClientUpdater(ClientCommunication cComm, Context context) {
        this.cComm = cComm;
        this.cntxt = context;
        BroadcastIntentUpdate = new Intent("update");
    }

    public void run(){
        while(true){

            String vomS1 = cComm.sendData("updateChat" + "~" + "$empty$");      //sends an update request to the server an receives the current chat-state
            if(!vomS1.equalsIgnoreCase("timeout")){

                Obj1 = GlobalClass.getInstance();
                String[] update = GlobalClass.decode(vomS1, ";");               //decodes the receives message                  
                String[] altchat = Obj1.getChat();                              //loads the stored chat protocoll from singleton


                if(!Arrays.equals(update, altchat)){                            //if the received message has new data...

                    BroadcastIntentUpdate.putExtra("message", update);
                    //for ".getInstance(cntxt)" the current Context is always needed right?
                    LocalBroadcastManager.getInstance(cntxt).sendBroadcast(BroadcastIntentUpdate);          //...it's sent to the activity
                    Obj1.setChat(update);                                                                                           //...and stored in the singleton
                }
            }    


            try {
                sleep(500);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }

    }
