Can I get JSONObject from Default value of Firebase Remote Config

Question

I need to fetch JSONObject from default value of Remote config in Firebase. By FirebaseRemoteConfig.getString(), it gets converted to the String, but not in the JSONObject, saying

org.json.JSONException: Unterminated object at character xx

I am attaching default values of remote config below:

  <entry>
    <key>welcome_message</key>
    <value>{"version" :1,"type":"category","name":"CATEGORY"}
    </value>
  </entry>

I am now attaching my Java Code below:

  String welcomeMessage = mFirebaseRemoteConfig.getString(WELCOME_MESSAGE_KEY);

  JSONObject categoryListInJson = new JSONObject(welcomeMessage);

Thanks in advance for the answers.

Can you paste the content of welcomeMessage ? and also in "org.json.JSONException: Unterminated object at character xx", what is the value of xx ? @vipul-k-patil — rkouye, Nov 09 '17 at 10:31
I've already done this in the question. String comes as: {version:1,type:category,name:BASE CATEGORY} and the value of "xx" is 36, i.e. the Space Character- " " — Vipul K. Patil, Nov 09 '17 at 10:33
Valid Json need quotes around field name and strings, like this {"version":1,"type":"category","name":"BASE CATEGORY"}. You may have it well formatted in your remote config, but you also have to make sure that the string in your runtime has a correct format. Also, the space may come from here BASE[Here]CATEGORY. So missing "", I guess. — rkouye, Nov 09 '17 at 12:32
That's the issue. I am not getting the proper format at runtime from the above stated format. Also, the issue of will be gone if double quotes are available after getString() — Vipul K. Patil, Nov 10 '17 at 16:36
I solved it using older gradle version. Check this answer: https://stackoverflow.com/a/48072301/5137352 — Nabin Bhandari, Jan 03 '18 at 06:36

It's bug on Android Studio 3.0 or above.

You're right. I solved it by using `classpath 'com.android.tools.build:gradle:2.3.3'` https://stackoverflow.com/a/48072301/5137352 – Nabin Bhandari Jan 03 '18 at 06:34

I saw a bug where the quotes from strings were getting stripped when picking values from default.xml

Can you try either of 2 things?

Enable developer mode and set cache expiration to 0. Then setup the JSON on firebase remote config console. Then make a fetch on device. This is because the bug isn't when JSON is fetched from console, it seemed only when pulling value from default xml.
Instead of using a string in default.xml JSON, use a number - and see if that works?

Thanks

There are multiple solutions for this problem

1. Use firebaseConfig.setDefaults(Map); for setting up the default configuration.

2. Use backslash () before Double Quotes(") in your String in .xml file.

3. Replace

classpath 'com.android.tools.build:gradle:3.0.1' with
classpath 'com.android.tools.build:gradle:2.3.3'
and 
google() with
maven { url 'https://maven.google.com' }

4. Add android.enableAapt2 = false in gradle.properties
