Answer 1

I can see 2 options to work that out: 1- Add an UncaughtExceptionHandler in your app, best in Application-derived class:

        mUEHandler = new Thread.UncaughtExceptionHandler()
        {
            @Override
            public void uncaughtException(Thread t, Throwable e)
            {
                // Close any opened sockets here

                defaultUEH.uncaughtException(t, e);
            }
        };

        Thread.setDefaultUncaughtExceptionHandler(mUEHandler);

But that only takes care of app crashes. If user kills the app, won't get in there at all.

2- Store some socket identification that allow you to close it when app restarts.

It's not perfect, but that could work-around your issue.
