使用服务在后台传输通话记录

Question

我正在尝试实现一个后台服务来将日志从呼叫日志数据库传输到服务器，并且我尝试了很多东西...计时器，线程无限循环...但似乎没有任何作用...以下程序可能是计时器循环...但它们在某些手机上都失败了...两种实现都遵循相同的方法，但实现不同（显然）...所以我的问题是我不检查导致无法发送数据的某些情况 .... i了解数据在睡眠时停止发送，但几乎所有手机都会恢复数据传输，但有些则不会....

编程结构。

    public class BootableService extends Service{
           @Override
           public IBinder onBind(final Intent intent) {

                  return null;
           }
           @Override
           public void onCreate() {

                  super.onCreate();
                  // use this to start my infinite thread here which is initialised inside this service class       
           }                    
           @Override
           public void onStart(final Intent intent, final int startId) {

                 //Use this to start a telophony listener that respond to call state and add the call from the call log to a blocking queue .... 

                 telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

                 // Create a new PhoneStateListener
                 listener = new PhoneStateListener() {

                        @Override
                        public void onCallStateChanged(int state, String incomingNumber) {

                            switch (state) {

                                case TelephonyManager.CALL_STATE_IDLE:
                                     System.out.println("phone IDLE");
                                     // calls a function to add the events to a queue. that have not been sent already. 
                                     addtoQueue();                                    
                                     break;
                                case TelephonyManager.CALL_STATE_OFFHOOK:
                                   System.out.println("Phone in use");
                                   break;
                                case TelephonyManager.CALL_STATE_RINGING:
                                   System.out.println("Phone Ringing");
                                       break;
                            }

                        }
                 };
                 // Register the listener wit the telephony manager
                 telephonyManager.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);
          }
          addToQueue()
          {
             //add to the queue add the call log not already transmitted to the server. 
          }

          class handler HandleStuff{

               this handles the data coming from the thread .,,,, the ID of the record sent. straight from the Android call log database.  and store it. 
          }

          Class ThreadRunning extends thread{

                run(){
                     while(true){
                         // This implements take the elements from the queue if present 
                         transmit 1 record/// 
                         sleep(20 seconds.)
                     }
                }
         }
}

该逻辑仅被触发一次。当手机启动或安装/打开应用程序时。如果该服务尚未开通。

为什么不直接使用 IntentService 呢？这样您就不必处理所有线程。您放入 onHandleIntent() 方法中的所有代码都将在单独的线程上完成，您可以根据需要花多长时间。
