unreachable code at line 104: youTubePlayerView = (YouTubePlayerView) findViewById(R.id.youtubeplayerview);

Question

Unreachable code Home.java /idg/src/com/idg/omv line 104 Java Problem

I'm getting an error stating unreachable code at line 104 which is:

youTubePlayerView = (YouTubePlayerView) findViewById(R.id.youtubeplayerview);

I'm not sure exactly why this is happening or what I can do to resolve it (I've never encountered it before). From what I've read it seems like the issue is in regards to part of my code being out of scope - I simply don't see how I can resolve the issue. (I've tried adding a few }'s without success)

Answer 1

 if (actionBarDrawerToggle.onOptionsItemSelected(item)) {
                return true;
            }
            return super.onOptionsItemSelected(item);

all statements which come after this code will become unreachable (except catch/finally). that is why you are seeing error.

Remove last return statement (or) put it in condition block (like first one).

Answer 2

return super.onOptionsItemSelected(item);

This line occurs before the error causing the function to return in all cases. You either need to put that statement in a condition (such as the if statement above) or remove it entirely.
