When setting the android webview to the html file that's apart of the app and then loading the admob ad the webview will reset and go back to original html file that was set in the MainActivity and if its already on it, it will reload the webpage
so if its `mywebView.loadUrl("file:///android_asset/index.html");` and the user goes to `main.html` and then gets an ad it will go back to index.html and that will also cause any JavaScript code I'm sending to my html file through the callback on rewarded ads not to go through/not reward the player.
If necessary I can provide my MainActivity.java file (it's a mess but it works... Other than the issue I'm having right now)
