Android : Static variable null on low memory

Question

I have an application which has some static variables. These variables are stored in an independent Class named DataContext. These variables are initialized from raw files a

Answer 1

I store a User object and a Client object in my static scope. I have noticed from time to time the reference becomes null. So now in my getters I check to see if this value is null and if so I restart the app.

Intent i = context.getPackageManager().getLaunchIntentForPackage(context.getPackageName());
                i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                context.startActivity(i);

I could have also chosen to reload the Client because I store the Access Token in prefs however I do so much initialization that I decided restarting the app would the best idea.
