Android Question Sending UDP "Packets" of a file

[Douglas Farias]

hi all
I want to send from my Android to my PC via UDP "packets" of 4096 bytes of a file in Base64-Strings.
Example:
The file has 20000 bytes...
It will send a string from 0 to 4096 bytes of the file.
Then send from 4096 to 8192 bytes...
Then send from 8192 to 12288 bytes...
Then 12288 to 16384 bytes....
And finally 16384 to 20000 (Cutting the last 480 bytes).
(All these bytes must be sended in BASE64-Strings)

I have tried it with several ways and I don't figure out, how to make this work.
Can anyone help me how to do this?
I already have figured out, how to send with UDP, but not, how to read in "packets" of 4096 bytes of a file. Maybe with a Loop or something?...

Thanks in advance

Why do you use UDP instead of TCP? UDP is less suitable for data transfer.

UDP is not safe for file transfers as there is no guarantee that all packets will arrive (unlike TCP which manages packets loss or order problems for you).

You can use InputStream to read the data in chunks.
