Android保存文件到本地后连接电脑无法查看 刷新不出来的结局办法

public void putSdcard(String s, String tep) { 
		try {
			FileOutputStream outStream = new FileOutputStream("/sdcard/" + tep
					+data.getOrderCode()+ ".txt");
			File file = new File("/sdcard/" + tep
					+data.getOrderCode()+ ".txt");
			outStream.write(s.getBytes());
			outStream.flush();
			outStream.close();

			
			Uri uri = Uri.fromFile(file);
			Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, uri);
			this.sendBroadcast(intent);
			showToast(this, "保存本地成功,连接电脑后查看");
		} catch (Exception e) {
			e.printStackTrace();
			showToast(this, "保存失败");
		}
	}

  
			Uri uri = Uri.fromFile(file);
			Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, uri);
			this.sendBroadcast(intent);

只需要增加三行代码 在文件保存完毕后发送广播刷新一下 就能在电脑中查看了
