I was wondering if there is an easy way to declare a variable in android programming. I am still teaching myself however I haven't been able to find the answer to this question. I would like to do something like:
var1 = 'variable1';
var2 = 'variable2';
So that it can be called later in the code by its Variable.
Thank you in advance.

To declare (create) a variable, you will specify the type, leave at least one space, then the name for the variable and end the line with a semicolon ( ; ). Java uses the keyword int for integer, double for a floating point number (a double precision number), and boolean for a Boolean value (true or false).
Kotlin uses two different keywords to declare variables: val and var . Use val for a variable whose value never changes. You can't reassign a value to a variable that was declared using val . Use var for a variable whose value can change.
Android Studio configuration environment variables. The Android Studio configuration variables contain settings that customize the location of configuration files and the JDK. On start-up, Android Studio checks these variables for settings.
Kotlin lateinit – To declare non null Kotlin Variables without initialization, use lateinit keyword during declaration of the variable. Initialization of that variable could be done at a later point in code.
I suggest learning Java fundamentals first. Declaring a variable is fundamental to Java programming language (and indeed many programming languages), its not just Android specific.
