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

If you weren't using raw files, I'd advise initializing when the class is loaded.

For instance,

public static Map myStaticMap = new HashMap();
static { //fill myStaticMap }

You do have some bigger concerns to worry about if you are loading files that way. For instance, what about I/O errors, or latency issues? You will get warnings in gingerbread (if you enable them) for doing I/O in your main thread. Perhaps you should have an object to retrieve these values instead of a class with static fields. (perhaps with a static cache, although you should synchronize on it before checking/changing it)
