I'm trying to make the java SNTP client ( [login to view URL] ) work on Android 4.2. The SNTP client is less than 500 lines of code include brackets and the actual amount of code modified to work on Android is minimal. I've converted some of it, but I'm now lost why my code is crashing. If you have familiarity with sockets and datagramPackets, this should be easy for you.
[login to view URL] is my workspace project that contains the JavaSntpClient Code, which was imported from the link above
[login to view URL] is my Android code. My code crashes at line 48 of [login to view URL] at [login to view URL]
Basically, your job is to either use my project "TEST" or write your own hello world code from scratch so that I can run an NTP-SNTP setup. Use the same outputs that appear in the print statements in the [login to view URL] for the [login to view URL] I'm okay printing the information Log, you don't have to make any views and can keep the hello-world view that is default.
What I've done:
Imported [login to view URL] and on line 421 added [login to view URL]
Copied over code from [login to view URL] to [login to view URL], added try-catch statements and converted [login to view URL] to Log.v
How to run an NTP server:
If you run a linux or mac OS system, your computer should have an NTP server on it without needing to do anything. Just make your computer broadcast a wi-fi network and connect to this. The static IP address should be the server you connect to for the NTP server. I recommend running SntpClient first on another computer to make sure you are able to connect and get the NTP time, which looks like:
NTP request sent, waiting for response...
