I have had a lot of problems to send data(a string of length 250 000)
to a server using java. I have probe a lot of things:
1. send byte by byte
i send 40Mbytes instead of 1Mbyte of data to server(because i use a
cicle "for()"and TCP/IP header add 40bytes and data is 1byte)
int ncc = 250 000
for(int a =0;a<ncc;a++){
out2.writeByte(utf8[a]);
}
only here i spend 15 seg counting with my watch (garbage
collector(GC) add 1,5 seg if Log info is correct)
2. send a string of length 250 000(in other words has 250 000
characters)
out2.writeByte(st);
//where st is a string
Here GC go crazy and the time is so large than i did't count it(maybe
near to infinite XD)
Now i think the best option is use NDK for send data, but i think is
hard to use and understand
I will be in debt with you if you can post info about how i can create
a good code to use socket with NDK. Please share info about how can i
learn to use the ndk, recomendation are wellcame. Seriously NDK is my
last hope
