Can't get titles to show in LogCat

Follwed the exact instructions, but for some reason I still can't get the titles to show in LogCat, any help would be great. Snippet of code is below.

     ***JSONArray jsonPosts = jsonResponse.getJSONArray("posts");
                for (int i = 0; i < jsonPosts.length(); i++) {
                    JSONObject jsonPost = jsonPosts.getJSONObject(i);
                    String title = jsonPost.getString("title");
                    Log.v(TAG, "Post " + i + ": " + title);***

You are missing closing curly brace for the for loop '}' in the above code. May be that's the problem...

It should be placed at the end of the 'for' loop... 

JSONArray jsonPosts = jsonResponse.getJSONArray("posts");
                for (int i = 0; i < jsonPosts.length(); i++) {
                    JSONObject jsonPost = jsonPosts.getJSONObject(i);
                    String title = jsonPost.getString("title");
                    Log.v(TAG, "Post " + i + ": " + title);

                 }                                // You were missing this curly brace


            ``` 
Hope it helps...

Try adding a breakpoint at the for line to see if jsonPosts.length() has a value (perhaps add its value in a Toast ). If it doesn't, then the loop will exit without executing.

Then you can step through the code to see what happens, if anything, when it reaches your Log.v statement.

Hope this helps.
