Sometimes I even miss a good old-fashioned goto.

public static final apiKey = xxx;
now you can access it as:
String key = globalVars.apiKey;
However, not that this is not a variable, its a constant.
According to convention, it should be in upper case:
public static final API_KEY = xxx;

David-
I am surprised anyone can even think to ask your question. The whole
POINT of Java is to provide support for object oriented methodology,
even making object disoriented methodology difficult. Yet you are
asking about the very antithesis of object oriented programming, the
infamous global.
Yes, I got the answer to this question from other people who didn't
phrase their answer in a manner like you did.
Thanks though.

Singleton is also one to be avoided however... just like global vars :)
However, as we're working on a (sort of) limited device, Singletons are a
way of life.

Hmm, perhaps this is semantics at this point. I don't think a singleton

If it's a single piece of state that's accessible globally,

No, but in terms of clarity, readability, and ease of debugging, there
is a *huge* difference in using a singleton to modify some globally
accessible object versus a classic global.
To me, the third option of don't use either one is almost always

Unlike in C/C++ or PHP you can't have global variables in Java (or
C#).
The closest thing to a global is a public static variable.
for example
class YourActivity extends Activity {
public static boolean bMyBoolean;
}
Now you could access it with
if(YourActivity.bMyBoolean) {
// Do
25 matches
