Android Build a Blog Reader Android App Getting Data from the Web Parsing Data Returned in JSON Format

Posted by Jeremiah Chersin

Having trouble with, parsing data returned in JSON format objective three.

The objective question follows below.

Finally, write a 'for' loop that loops through 'jsonBooks'. In each step of the loop, use 'getJSONObject(int index)' to get a JSONObject from the array. Then use the 'Log.i()' method (with "CodeChallenge" as the tag) to write the book title, a comma, a space, and the number of pages. Ex. output: 'Book title 1, 300'.

Not quite sure how I am supposed to do this part. Any help is greatly appreciated.

Hey Jeremiah,

For the next question, remember posting the code you are having issues so we can help you based on your mistakes.

For now, to solve your code, the answer should be something like this

  for (int i=0; i<jsonBooks.length(); i++){
  JSONObject jsonBook = jsonBooks.getJSONObject(i);
  Log.i("CodeChallenge", jsonBook.getString("title") + ", " + jsonBook.getInt("pages"));
  }
