Now I know I might not receive the help I'm looking for because Cemetech isn't about Android coding, but I know at least Kllrnohj works for Google so I thought I'd throw this question at ya Cemetech.
I'm creating a VERY simple application for android, for a game (Ogame).
Now I may add on to this application, but for now this is all I want it to do;
Code:
- The user Inputs their level,
- If the user inputs < 5000...
- It multiplies the number by 5 to get the max
- It multiplies the number by .2 to get the min
- If the user inputs 5000 < X < 24999
- It multiplies the number by .2 to get the min
- If the user inputs >25000
- It just displays "You can attack anyone > 5000"
My question is; how do you use variables (Such as input = X) and then from there us that X in equations to create an output?
What you're asking seems to be a generic question about Java, and it isn't Android-specific.
To use a variable in Java, first decide the type of variable you want to create (int, double, char, String, boolean, etc.) You can declare variables in Java like this:
Code: int Num1;
double Num2=3.4;
char Character='B';
This code declares Num1, an integer with no value, Num2, a double with a value of 3.4, and Character, a char with a value of 'B'. To use that variable, you can plug it into any expression and it will evaluate using your variable. For example:
Code: //using variables from before
System.out.println("Value of a is "+a+" and value of b is "+b);
double c=b*2+1; //Multiply b by 2 and add 1
If statements (and if-else and if-else if-else) use boolean variables and expressions. Here is some code that checks if a number is less than 5:
Code: int Number = 3;
if (Number<5) //Boolean expression
System.out.println("Number is less than 5");

For some possible Java code that essentially does this, using standard, non-android specific routines:
Code: int userlevel = (new Scanner(System.in)).nextInt(), min, max;
if(userlevel<5000) {
max = userlevel*5;
min = (int) 0.2*userlevel;
} else if(userlevel<25000) {
min = (int) 0.2*userlevel;
} else { System.out.println("You can attack anyone > 5000"); }
And as Souvik said, this has nothing to do with Android-related questions yet, as you are essentially asking standard Java questions -- which is fine, once you build a foundation with these and then get comfortable with the Android API you can go on to build the latest and greatest Ogame-like game 
I'm not creating a game, just a simple app to tell you which levels you can attack in a game
Thanks though guys, I was thinking too much android, too little java, you guys rock
EDIT!!: Okay, so I have the calculation parts down pat, but uhh...
How in the world do I take the input from the edittext and turn it into a variable?
If needed I can post my main.xml and my .java file so far.
I'm not an Android expert, but it seems like you would use the getText() method from the
EditText class.

I think you're right
