Hey Aboobaker, you had most of the correct code in your original post. What happens if you replace this code:

(){
  String Title="lkjokj";

return Title ;
}

with just a semicolon? Adding a member variable should only be one line of code. Parentheses and curly braces are for methods, not single variables. :)

what do you mean with just a semicolon?

Ismael Soumahoro , the code I highlighted above isn't needed for this challenge. Declaring a member variable just needs three words and a semicolon. Check out the 2:50 mark of this video. The example in the video is for a TextView member variable, but in the challenge it just needs to be a String variable.

Maybe you can try the following code:

public String mTitle;

Dear Aboobaker,

Syntax for member variable is [DataType] [VariableName];

For Example I want to create a String member variable of name "MyName", then the code will be. String MyName="";

Dear Aboobaker, You are doing wrong code. Correct code is

public String mTitle;
