i've been dealing issue keeps coming , i'm getting quite frustrated. i'm trying connect database via template php webservice found online, sending jsonobjects. keep getting either ioexception or protocolexception when trying response code server cause being "unexpected end of stream". error message cryptic , have no idea error in java or php code. posted code, can take look:
stack trace:

change :
//the offending line int responsecodehttp = conn.getresponsecode(); system.out.println("responsecode http "+responsecodehttp); outputstream os = conn.getoutputstream(); os.write(bytearray); os.flush(); to:
outputstream os = conn.getoutputstream(); os.write(bytearray); os.flush(); //not more offending line int responsecodehttp = conn.getresponsecode(); system.out.println("responsecode http "+responsecodehttp);
