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.

Print String wc , is it a well-formated json ? – Rumor

No, it's not @semako – Samira

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 – Rumor

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- " " – Samira

looks like xml tag value has json. – Ifni

Yes, I need to pass it as json. @Ifni – Samira

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. – Rumor

That's the issue. I am not getting the proper format at runtime from the above stated format. Also, the issue of <SPACE> will be gone if double quotes are available after getString() – Samira

I solved it using older gradle version. Check this answer: https://mcmap.net/q/507495/-android-firebase-remoteconfig-getstring-method-is-removing-quotes-from-string-inside-default-xml – Lazes

any updates for this thread? – Pedropedrotti

Answer 1

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://mcmap.net/q/507495/-android-firebase-remoteconfig-getstring-method-is-removing-quotes-from-string-inside-default-xml – Lazes

Answer 2

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?

1. 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.
2. Instead of using a string in default.xml JSON, use a number - and see if that works?

Thanks

Answer 3

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
