This error means that you are trying to invoke the method size()
on an object (myKeyStore
) that has not been initialized with a value. In other words, myKeyStore
is currently null
, and you cannot call a method on a null
object.
To resolve this error, you need to initialize myKeyStore
with a valid value before trying to call any of its methods.
