藍牙運行接收失敗

Question

我使用的代碼示例在這裏找到http://goldenhillbooks.com/blog/?p=59#respond。我用下面的代碼修改了Run。我遇到的問題是當我斷開應用程序崩潰連接的藍牙設備之一。如果我評論運行部分，它不會崩潰。

有人能告訴我發生了什麼事嗎？

public void run() { 
    final byte delimiter = 10; //This is the ASCII code for a newline character 

    byte[] readBuffer; 
    int readBufferPosition; 
    readBufferPosition = 0; 
    readBuffer = new byte[1024]; 
    // Keep listening to the InputStream until an exception occurs 
    while (threadNumber>0) { 
     try { 
      int bytesAvailable = inStream.available(); 

      if(bytesAvailable > 0) { 
       final byte[] packetBytes = new byte[bytesAvailable]; 
       inStream.read(packetBytes); 
       //myLabel.setText(packetBytes.toString()); 
       for(int i=0;i<bytesAvailable;i++) { 
       byte b = packetBytes[i]; 
       if(b == delimiter) { 
        byte[] encodedBytes = new byte[readBufferPosition]; 
        System.arraycopy(readBuffer, 0, encodedBytes, 0, encodedBytes.length); 
        final String data = new String(encodedBytes, "US-ASCII"); 
        readBufferPosition = 0; 
        Log.d(TAG, 
         "BtConnectionThread run while loop: received from arduino:" + data); 

         Intent e = new Intent("com.Ryan.myhue.BT_LISTENER"); 
         e.putExtra("notification_event",data); 
         mycontext.sendBroadcast(e); 

       } 
       else { 
        readBuffer[readBufferPosition++] = b; 
       } 
       } 
      } //bytesAvailable 
     } catch (IOException e) { 
      Log.e(TAG, 
        "BtConnectionThread run while loop: problem reading"); 
      e.printStackTrace(); 
      break; 
     } 

    } 
}

我解決了這個問題，通過在斷開連接中設置一個標誌來退出運行，如果斷開連接。

while (this.running == true) {
