What do these lines in my Java or Android project mean?
@SuppressWarnings("deprecation") @SuppressWarnings("unused")

You can use the @SuppressWarnings annotation to suppress warnings whenever that code is compiled. Place the @SuppressWarnings annotation at the declaration of the class, method, field, or local variable that uses a deprecated API.
@SuppressWarnings instruct the compiler to ignore or suppress, specified compiler warning in annotated element and all program elements inside that element. For example, if a class is annotated to suppress a particular warning, then a warning generated in a method inside that class will also be separated.
@SuppressWarnings("unchecked") is used when Java generics just don't let you do what you want to, and thus, you need to explicitly specify to the compiler that whatever you are doing is legal and can be executed at the time of execution.
Adding the @SuppressWarnings({ "resource" }) should remove the warning for a potential resource leak. Adding a list for other ones, it's for Eclipse but they should be fairly similar for reference.
The @SuppressWarnings annotation disables certain compiler warnings. In this case, the warning about deprecated code ("deprecation") and unused local variables or unused private methods ("unused"). This article explains the possible values.
