I'm not positive about this, but I think i just ran into a bug using static
vars.
I'm trying to fix it now, but I think my vars are getting GC'ed as the
phones runs low on memory and reinitialized when I need them again.
Which of course means that they get reinitialized to the default value
To clarify, that's *not* an Android or Java bug, but a bug in my own code :)

What probably happens us that the process gets killed and then relaunched.
The relaunch may execute a code sequence different from when your app is
launched for debugging or from the Launcher (i.e. main activity first), and
your code that initializes and uses those globals may be sensitive to

What is the best way of going about setting up global variables? There
will be like 5-6 global variables that I would like to set when my app
is launched that are then available for any code anywhere in my app.
I did something similar to this under Mojo on WebOS. I just set some

IDK about best, but easy: public static values somewhere that you set up
in a custom Application class.
The best way is to avoid them like the plague...
If you can't then you can either subclass Application and make them
available there or you can use SharedPreferences...

Justin,
Thanks for the information, I will have to look into just what
subclassing the Application means/is and also SharedPreferences.
That said, why avoid them like the plague? If you don't use global
variables then just how do you get some kind of static value (which is
really what I'm
Or you can use public static like TreKing suggested...
Personally, if I find that I'm having to use Global variables, then that
means I'm most likely doing something wrong, and I try to restructure what
I'm doing. Generally I can find a way to accomplish the same thing without
them and have a
I tend to do what TreKing suggested. I have a class called CommonVariables
that really holds static strings for Flurry event names, the year parameter
for my app (it's seasonal and changes once a year) which is used all over
the place, and things like that.

Global variables are one of those things, like Singletons, that on the
surface seem to make life easier, then get abused like a step-child to the
point of making
Oh, come on, guys, it's not that bad :)
Sometimes I even miss a good old-fashioned goto.

Ok, trying to do this but struggling.
I created a class as follows:
package com.dtwconsulting.golfcaddie;
import android.app.Application;
public class globalVars extends Application{
public String apiKey = ;
public String getApiKey() {
return apiKey;
}
}
If you define to use your custom application class in the android manifest
file you can get the class from your activities.
Inside your activity, simple use (MyAppliction) getAppliction() and then you
can access your variables.
If it's static global variables you're looking for. Then you would
Sorry, I am new to Java and Android.
I don't get what you are saying. I added the following
android:name=globalVars to the manifest.
But I still don't understand how I can get the value of the apiKey,
which should be .
Ah, sorry for my brief explanation.
Basically, you have to decide what you want.
You can either encapsulate your application using Application sub-class
which all your activities can then access.
Or, you can have a java class in which you store your global variables IF
they don't change at
Like this:
globalVars myApp = (globalVars)getApplication();
myApp.getApiKey();
Or... since you made the variable public you can do this:
myApp.apiKey;
