					PackageManager.GET_ACTIVITIES);// com.test.app为自己应用的包名
			Log.d("!!", "!!" + ai.uid);
			long received = TrafficStats.getUidRxBytes(ai.uid);// 获取某个网络UID的接受字节数
			long sent = TrafficStats.getUidTxBytes(ai.uid);// 获取某个网络UID的发送字节数
			Toast.makeText(mContext, "累计接收数据" + received / 1024 + "KB",
					Toast.LENGTH_SHORT).show();
