我对自己的调试时间，错误的一些问题

Question

第一：

10-26 17:43:07.454: WARN/dalvikvm(6371): threadid=3: unable to interrupt threadid=19 
10-26 17:43:07.487: DEBUG/dalvikvm(6371): GC freed 279 objects/259776 bytes in 208ms 
10-26 17:43:07.487: WARN/WindowManager(2215): Attempted to add application window with unknown token HistoryRecord{46366130 spexco.hus.cepvizyon/.ViewCam}. Aborting. 

我现在不能看其他错误，但在第二次，我要学习如何停止处理程序？ 我的处理程序代码是：我用“handler.sendMessage（new Message（））;”

private Handler handler = new Handler() { 
    public void handleMessage(Message msg) { 

     try { 

      bmp = CameraManagerScreen.ActiveCam.getCurrentImage(); 
      bmpl = CameraManagerScreen.ActiveCam.getCurrentLenght(); 
      if (bmpl != bmpltmp) { 
       if (speed.getVisibility() == 4) { 
        speed.setVisibility(0); 
        counter++; 
       } else { 
        speed.setVisibility(4); 
        counter++; 
       } 
      } 
      bmpltmp = bmpl; 

      if (bmp != null) { 
       if (CameraManagerScreen.ActiveCam.isConnected()) 
        m_ProgressDialog.dismiss(); 
       imageView.setImageBitmap(bmp); 

      } 
      if (isDemo && counter == 10) { 
       counter++; 
       CameraManagerScreen.ActiveCam.cancel(); 
       CameraManagerScreen.ActiveCam.setConnected(false); 

       m2_ProgressDialog.show(); 

      } 

     } catch (Exception e) { 

     } finally { 
      if (isDemo && counter == 10) 
       sleep(999999999); 
      sleep(50); 
     } 

    }; 

    public void sleep(long delay) { 
     this.removeMessages(0); 

     sendMessageDelayed(obtainMessage(0), delay); 

    }; 
}; 

Answer 1

“无法中断”当您尝试中断一个等待的线程，但该线程在它似乎被“卡住”的状态，因此，VM放弃并丢弃中断问题出现。

从2.2（“froyo”）开始，线程中断机制发生了变化，不再发生。

这是否可靠地发生？
