Why am I getting a null object when creating a JSONObject from string?

I've written a Java Method for an Android Studio (3.0.1) project that creates a JSONObject from a String. Now I've written a JUnit test to test that the JSON object is correct.

The problem is always that the JSONObject is NULL.

For example, I tried running the following code:

String response = "{\"songs\":\"title\"}";
System.out.println(response);
JSONObject submitPlaylistResponse = new JSONObject(response);
System.out.println(submitPlaylistResponse.toString());

The output is:

{"songs":"title"}
null

Why is my JsonObject still null? What am I missing? I feel like I'm missing something trivial/simple.

After viewing JSONObject code I found this:

public String toString() {
   return "null";
}

As you see, method always returns "null" string not null object. In this case, if the task is to check the correctness of your JSONObject you can follow @G.Dator answer or use String toString (int indentSpaces).

Probably you are using wrong library. Check your import. It must be like this. org.json.JSONObject; I've checked your code and it's working on my android studio 2.3
