Android - Import Java Class into Activity

I have a java class called Constants filled with variables. And currently if I want to use that variable in an activity I have to use it like this.

Constants.variable = "blah blah";

Is there a way to import my Constants class into my activity so that I can just use it like a normal variable like this 

variable = "blah blah";

I have tried 

import com.myname.appname.Constants;

but this doesn't seem to work.

Thanks for the help in advance.

You have to declare "variable" as static and import the class as static by following syntax

    import static com.myname.appname.Constants.*;

considering Constants.variable is a static variable

import static com.myname.appname.Constant.*;

this will import all you static variables in you current namespace only the static variable 

import static com.myname.appname.Constant.variable;

now you can use variable like a normal variable

See this SO question : Meaning of the import statement in a Java file

try:

import com.myname.appname.Constants;

Are you using an IDE?

Also, they way you have stated is how you are suppose to use a Constants class. But you are not suppose to assign anything... because the variable are suppose to be constant, ie. static final
