Anki-android: Not getting value in __viewer__.html

[infinyte7]

Reproduction Steps

1. I made this variable accessible to other function

SpannableString newCount;

1. Added this to card.js

function newCardCount(value) {
    window.newVar = value;
    console.log("value from card.js : " + value);
}

1. After that added this to onPageFinished

 @Override
        public void onPageFinished(WebView view, String url) {
            Timber.d("onPageFinished triggered");
            drawFlag();
            drawMark();
            view.loadUrl("javascript:onPageFinished();");
            view.loadUrl("javascript:newCardCount(\"" + newCount.toString() + "\")");
        }

1. I am getting value in console calling from card.js but when I am not getting value in __viewer__.html

<script>
console.log("value from __viewer__.html : "+window.newVar);
</script> 

It giving undefined.

Expected Result

It should give the value of newCount.

Actual Result

It is giving undefined.

so you know the method is executing (you have the console.log from debugging) but window.newVar is undefined. You should check if window.newVar has a value even after you set it, right in that function. Perhaps there is some oddity with referring to the variable? I don't have a lot of experience with the javascript environment inside Chrome unfortunately so I'm not sure sorry

Shot in the dark: HTML errors causing JS execution inside __viewer__.html to fail. (#5273)

[infinyte7]

The function newCardCount(value) called before onPageFinished. So, might be it should called from other function.

Thank you @mikehardy @david-allison-1
I figured out it.
Using this I get the value

<script>
setTimeout(function(){
 console.log("value from __viewer__.html : "+window.newVar);
}, 1000);
</script>
