- Thats not a good way to read a stream. look up on how to use buffers
- Its a horrible idea to perform findViewById in a loop. you should only
do it once before the loop.
- never do long processes on the main thread. especially not network
access. look up how to background tasks in android
- setText replaces the entire text with the new value. seems more likely
you'll want to collect all the input before you set it to the view or at
least concat it instead of replacing it.
