I get "Couldn't open socket" error from my Android app after it runs
for a few hours.
A thread is in a while loop doing URL.openConnection.... after many of
these (about 1000), I get the error. Has anybody encountered this and/
or have a fix for it? Any help would be appreciated.
The snippet of code in the while loop body is:
URL myURL = new URL(urlString);
URLConnection ucon = myURL.openConnection();
inStream = ucon.getInputStream();
input = new Scanner(inStream);
.....
inStream.close();
log file below:
