启用StrictMode后，检测到有问题

strictmode 设置如下:

StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
.detectDiskReads()
.detectDiskWrites()
.detectNetwork()
.penaltyLog()
.build());
StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
.detectLeakedSqlLiteObjects()
.detectLeakedClosableObjects()
.penaltyLog()
.penaltyDeath()
.build());

下面是strictmode 输出的信息，这块儿代码仅仅是修改了包名。

应该是没有close s1导致的

@huangyanan 解决了吗？说下方案

@JackyAndroid 解决了，关注一下那个socket 对象的初始化和关闭，初始化的socket并没有被关闭。

改后如下，请确认下是否正确，另外修改Socket80Test影响范围有多大？

public class Socket80Test extends BaseSpeedTest {

    static final int TIMEOUT = 5 * 1000;

    @Override
    public int speedTest(String ip, String host) {
        Socket socket = null;
        try {
            long begin = System.currentTimeMillis();
            socket = new Socket();
            socket.connect(new InetSocketAddress(ip, 80), TIMEOUT);
            long end = System.currentTimeMillis();
            int rtt = (int) (end - begin);
            return rtt;
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (null != socket) {
                    socket.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return SpeedtestManager.OCUR_ERROR;
    }

    @Override
    public int getPriority() {
        return 10;
    }

    @Override
    public boolean isActivate() {
        return true;
    }
}

无发现异常影响，我这边线上已经使用修改一年了。
