Answer 1

Found It, the problem is that I was thinking

settings.getBoolean(keyPurchase,false) 

returns the value of keyPurchased variable but the fact is it only returns the variable itself not its value so I fixed the problem by changing the method of my class to this:

public boolean appIsPurchased(){
    return settings.getBoolean(keyPurchase,false);
}
