WebView returns bad window.innerHeight

Question

I have an application that makes use of the Android WebView, as well as some JavaScript. When my WebViewClient calls onPageFinished(), I alert my JavaScript to run

Answer 1

After some reading,another solution has occured. in java code, we can use

new Handler().post(new Runnable(){ 
    @Override 
    public void run(){
        webview.loadUrl("...")
    }
}); 

add it to QueueMessage,and delayed the js to execute,and it works.
