[Android Mode4.0] oscP5, udp library error

Good morning. After updating your Android version,

1. The oscP5 library does not work.
2. The udp library does not work.

Is there a solution?  
Or is there an example source code for udp?

_Did oscp5 ever work with Android? I thought you were required to use the native networking stack on Android._

**And are you sure you want to use UDP for connections?**

UDP **does not** guarantee delivery of data. If you **need 100% of the data** and in correct order, you can use **sockets** , which utilize TCP/IP.  
If you are developing a audio chat package loss probably isn’t your concern, the audio might get a bit choppy, but when developing a chat every package, every message should arrive.

For custom socket handling:  
[DatagramSockets Reference](https://developer.android.com/reference/java/net/DatagramSocket) (UDP) & [Sockets Reference](https://developer.android.com/reference/java/net/Socket) both on Android Developers

I am not yet experienced in networking. You should probably wait for another answer. 😉

@GWAK === , @macbrayne  
oscP5 last update: 2011; so it is impossible that this lib ever works with android mode…@macbrayne is right: use the android API for that and use sockets tcp/ip
