Apps How to only initialise a variable on app first run

[emb16social]

I'm trying to pass data between pages using intent extras and I have 2 pages that pass different data but every time I pass data using intent extras on one page, the other overwrites data on the other page.



Here's my code:

I use a class I call global0 with setter and getter and reset methods that use static variables that only change if you specify them to change you can access the data even between activities.


public int getVar0(){
return var00
}

public static int var00 = 6;//default value

public void setVar0(int var0){
var00 = var0;
}

public int getVar0(){
return var00;
}


public void reSetVar0(){
var00 = 6;//default value
}


//set variable
global0 global0 = new global0();
global0.setVar0(66);

//get variable
int getVar0 = global0.getVar0
