Hello.
Yes that is what i want it to do.
This is a background thread that is started RunThread = true on
"onResume()" and i set it false on "onPause()" and on "onStop()".
So as long the activity is active then this should run in background and
connect a web server and later in the code iam processing the String xml (i
disabled that part now when iam locking for the memory leak)
Here is a short period of my logcat when this loop is running.
