This is strange...
char s[100];
sprintf (s, "%d,%d,%d,%d,%d,%d,%d",
value0, value1, value2, value3, value4, value5, value6);
Serial.print (s);
I am getting as an output in my Android device while debugging following string "530,983,62,128,0,26,"
As you can see there is a comma, but no 7th value even tho it is there if I check from my PC Arduino Serial Monitor
