The past week I was roaming with a poor contract so I mostly kept the data connection turned off. The phone was performing very slowly over this period. I'm wondering if it's possible for apps to block with a lack of data connection and therefore eventually use up resources more than they should?

We obviously can't debug your system at the time this happened, so I doubt that you will get a definitive answer. Besides that: What do you expect from the answer? I never had those problems when the data connection was disabled. But is possible that a bad behaving app caused this. – Flow♦ Sep 4 '12 at 14:36

Just a FYI from a dev perspective: In newer versions of Android SDK (I think since ICS, maybe GB) any http request (e.g. an API call to a webservice) must be called in it's own thread (e.g. AsyncTask), otherwise an exception is thrown at runtime. Any dev that doesn't do "long things" in AsyncTasks/threads is designing their app poorly. – Bryan Denny♦ Sep 4 '12 at 14:43
@BryanDenny Yes, I think it's highly possible that devs are not always using async tasks to do requests. Even if they did though , you think it could be possible that the async queues could build up and clog up the system with status polling? – barrymac Sep 4 '12 at 15:04
@Flow I'm asking for developers opinions to give me an idea if bad practices in app development can cause a system to get bogged down due to not having a data connection – barrymac Sep 4 '12 at 15:07
I found an app called watchdog which is handy for detecting high resource usage apps. Dropsync was using a lot of time scanning folders, could be a culprit – barrymac Sep 4 '12 at 15:08
