ERROR: "Syntax error on token"; "expected" Why?

Question

Now I'm going crazy. Thought about it, thought about some kind of IDE error. Maybe I'm blind and can’t see anything ... but everything was fine just an hour ago. I commented on all the code and am not going to compile it.

public class CityExplorerPoi extends Activity { private POI displayedPOI = null; private MediaPlayer mPlayer; enum audioState { Idle, //Idle, not initialized Initialized, //Initialized, not prepared Prepared, //Prepared Started, //Playing Stopped, //needs preparing Paused, //can be Started or Stopped Preparing, //... End, //Released, useless Error, //... PlaybackCompleted //can be Started from beginning or Stopped }; audioState aState; <<<<<<<<<<ERROR mPlayer = new MediaPlayer(); } 

This code has a compiler error in the line marked ERROR, which indicates a syntax error on the token ";", expected

With the enum declaration, I tried to do without; after}. Tried to put; after the last record (PlaybackCompleted) and still nothing ???

Any ideas? What I miss: (

Answer 1

This is an actual problem:

 mPlayer = new MediaPlayer(); 

This is just an instruction - but it is not in the constructor, method or other initializer. It is not clear why you are not just assigning a value at the declaration point:

 private MediaPlayer mPlayer = new MediaPlayer(); 

I would also recommend removing the redundant semicolon at the end of the listing declaration.

Answer 2

This is not an IDE error.

You have a semicolon after closing} the listing. This is not required.

You also have mPlayer = new MediaPlayer(); floating in your code, outside the method.

I would suggest reading a good Java book, for example, this one: http://www.amazon.co.uk/Agile-Java-Crafting-Test-Driven-Development/dp/0131482394

And a good Android book: http://www.amazon.co.uk/Android-Application-Development-Dummies-Computers/dp/047077018X/ref=sr_1_1?s=books&ie=UTF8&qid=1333106527&sr=1-1

Answer 3

The problem is here.

 mPlayer = new MediaPlayer(); 

You assign a value at the point of declaration. Similar.

 public class CityExplorerPoi extends Activity { private POI displayedPOI = null; enum audioState { Idle, //Idle, not initialized Initialized, //Initialized, not prepared Prepared, //Prepared Started, //Playing Stopped, //needs preparing Paused, //can be Started or Stopped Preparing, //... End, //Released, useless Error, //... PlaybackCompleted //can be Started from beginning or Stopped }; audioState aState; MediaPlayer mPlayer = new MediaPlayer(); }
