Passing data from Activity to JS

Hi, 

I'm very new to Wikitude API.
Just wondering how could I pass my data (from my MainActivity) to Javascript so it could use it to filter the results that it obtained from the database and use it to load the POI accordingly.  

Please provide a detail guidance as I'm really new in this. 

Thanks in advance.

Hello Jacob,

Please have a look at the documentation here.

I have tried but still unable to pass data
My AR Activity
@Override
protected void onPostCreate(Bundle savedInstanceState){
    super.onPostCreate(savedInstanceState);

    architectView.onPostCreate();
    try{
        final JSONArray jsonArray = generateUserInformation(LoginActivity.user);
        this.architectView.load("file:///android_asset/detail/index.html");
        this.architectView.callJavascript("World.loadUserFromJsonData(" + jsonArray.toString() + ")");
    } catch (Exception e){

    }
}
My Javascript 



loadUserFromJsonData: function loadUserFromJsonDataFn(userData) {
    var user = userData.user;
}
Hello Jacob,

There are a couple of errors in your code. First of all, since the calls are asynchronous in javascript, it could be that you are calling the callJavascript method before the loading of the index.html file is completed. Therefore, I would suggest you move the callJavascript method outside of the onPostCreate (maybe put it in the onArchitect World loaded function). Second of all, make sure that the LadUserFromJsonData is actually a function inside the World, otherwise the line below is wrong
loadUserFromJsonData: function loadUserFromJsonDataFn(userData) {
Thanks

Hello Jacob,


Can you pass data from MainActivity.java to JavaScript? I have no idea to do that. I have  JSON data in my MainActivity.java. I want to pass it from MainActivity.java to JavaScript.

Can you give me an example. Thanks

I use WIkitude SDK 6.1 because my minimum sdk app is 16.
