安卓 : How to get internet connection upload speed and latency?

Question

我想知道设备网络上传速度和延迟，我试过FTP文件上传但没有成功。谁能帮我确定网络上传速度？

Answer 1

获取当前网络连接类型:

TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
int networkType = telephonyManager.getNetworkType();

以及延迟:

String host = "172.16.0.2";
int timeOut = 3000; 
long[] time = new long[5];
Boolean reachable;

for(int i = 0; i < 5; i++)
{
  long BeforeTime = System.currentTimeMillis();
  reachable = InetAddress.getByName(host).isReachable(timeOut);
  long AfterTime = System.currentTimeMillis();
  Long TimeDifference = AfterTime - BeforeTime;
  time[i] = TimeDifference;
}
