android webview rendering is showing a White Page

Question

Sometimes, when I load my webview with loadUrl, the website is not showing up until I touch the screen or scroll.

It\'s like I have a webview drawing problem.

Answer 1

I'am not sure, I don't have the whole code, but I think is related to the webViewClient implemented in this function:

public boolean shouldOverrideUrlLoading(WebView view, String url){
    // do your handling codes here, which url is the requested url
    // probably you need to open that url rather than redirect:
    view.loadUrl(url);
    view.setVisibility(View.VISIBLE);
    return false; // then it is not handled by default action
}

here is the officiel definition:

public boolean shouldOverrideUrlLoading (WebView view, String url)

Try to test with your code without implementing shouldOverrideUrlLoading, or make it return true.
