The local variable xxx is never read

Question

This is my code:

boolean startGameBoolean;
Bundle extras = getIntent().getExtras();
extras.getInt(\"startGameBoolean\");
if (startGameBoolean = true){
    counte         


        

Answer 1

Shouldn't it be startGameBoolean = extras.getBoolean("startGameBoolean");?

in the code you gave, boolean startGameBoolean; is not used anywhere. the warning means that although you declared it, it is not used in the block where it lives, therefore could (should) be removed.

Edit:

After seeing your addition, you use startGameBoolean, but you assign to it, while you should compare to it:

if (startGameBoolean == true){
//                    ^
    counter.start();
}

Also, assign the result of getBoolean() to the variable as I wrote in the first statement.
