I have a new Samsung Galaxy Tab 4 10.1 tablet (SM-T530NU) and after about a week I am starting to see a lot of java. Net read, timeout exception errors. Running Android 4.4.2 KitKat. Any ideas?
Is this a web browsing issue? Or a tablet use issue? My knowledge of Java is right up there with my knowledge of quantum physics. I probably understand quantum physics a little bit better.
Thanks for your interest. What's frustrating is that I just spent a lot of money upgrading from a Galaxy Tab 2 to a Tab 4 because of all these Java. Net errors, mostly read error timeouts. I used my new tab for several days w/o any problems building my new Tab copying old apps from/to using WiFi Direct & Play Store downloads.
It seems to happen more when using "Profimail" (email client) as it's attempting to sync the inbox. Now it's happening more randomly. I am using a few WiFi supposedly assist apps? I am a retired Developer but not at all experienced in the mobile world, just PC's and main frames. Thank you…
I know you've probably got all of your apps installed and setup now, but the best way to isolate the issue and figure out exactly what app it's coming from is to uninstall all of them (this is most easily done by doing a factory reset from the main settings menu) and slowly re-install them, giving each app enough time to get setup and running. Hopefully, then you'll be able to pinpoint it to the app.
I can't say that I've ever seen a Java.net error on an android device and I've been using them since 2008, but I'm also not familiar with Profimail, so I'm thinking it's got to be an issue with the coding in an app and/or how it's attempting to access the information it's supposed to access.
If you'd rather start smaller than uninstalling all apps, I'd uninstall Profimail and see if that gets rid of the issue, then it's a matter of trying to figure out how/why it's giving those errors if it's the culprit.
If you moved to the Tab 4 because the Tab 2 was having these same errors, I definitely wouldn't recommend copying too much over too soon because, again, it'll be easier to figure out where the problem lies by adding things one by one and observing them.
Bottom line, though I've already pretty much said it, sounds like it's more of an issue with a certain app (or maybe more than one) having java troubles, so we'll need to figure out which one(s) it is before we can try to figure out why they're doing it and how to fix it and/or get you in touch with the developer of the affected app(s) in the hopes that they still support it and can help with the issue.
Java is completely installed and managed by system installs...or OTA's. It is a fairly older device and sounds to me like a programming issue of an OTA. I would perform a factory reset as well, then slowly add apps one by one as suggested by @Jonny Kansas. If this does not solve the issue..You will probably need to re-program the device.
I using "WiFi High Performance Widget 1.19" and "WiFi Toggle Widget 1.2.7". Actually ,I have 3 email (IMAP) Clients installed. I think the offending app might be my favorite one. It's called "Profimail Go 4.16.00". The actual server/client is Runbox.Com a Norwegian software company that provides the email software and I've been using their software for over 6 years now. I think I can declare this problem solved but I don't know what to do on the forum to stop anymore replies to me on this issue? Thanks everyone for such kind attention to my problem… Happy New Year all!!!
