Is there better way to get values from Deck to WebView?

[krmanik]

Reproduction Steps

I have added following codes to AnkiDroid.

card.js

view.loadUrl
AbstractFlashcardViewer.java

Added custom card layout using css and js to deck template.
Anki-Custom-Card-Layout

Expected Result

Is there a better way to following values without using setTimeout .

Deck Title,
ETA,
New, Learn, Review Card Counts
Mark,
four button or three button is there 

I get values ( cards count, title, mark, eta ) but by using setTimeout function of javascript.

Actual Result

WebView should get values without using setTimeout.

Reason

It will help in card creation with custom layout.

Debug info

Refer to the support page if you are unsure where to get the "debug info".

This is my idea. Make available all details about current card to WebView and then using css and js card can be redesigned with many possibilities.
card.js have following functions

showAnswer()
buttonEaseAnser1()
buttonEaseAnser2()
buttonEaseAnser3()
buttonEaseAnser4()
markCard()
CardCount()    //  have count number of new card, learn card, review card  
DeckName()   // have deck name value 
getETA()        // have value of remaining time to review the current deck

I have found answer using this.
https://github.com/SimonLammer/anki-persistence

Get all values to persistence value. And then use it for next.
Following value need not to be made available using setTimeout

ankiDeckName
total card count from first card
total = ankiNewCard + ankiLrnCard + ankiRevCard

Fascinating, that's a great project! I want to tag @SimonLammer directly to say that the AnkiDroid project is thinking through what the best is to have an "officially sanctioned" card template or distribution method or similar that would bundle a few things that any use of advanced web technologies in the WebView would want. Persistence is such an obvious one - it's the first thing to solve.

I personally would love the wisdom of the community already working in the area
