Android Webview Displaying Blank Page

October 27, 2023 Post a Comment

I have an android application that I am developing using the emulator running on android 2.3.3 with an embedded WebView in a framelayout nested in a linearlayout (vertical). No mat

Solution 1:

WebSettingssettings= wbView.getSettings();
settings.setDomStorageEnabled(true);

Solution 2:

It might be a bit too late, but I wanted to share my experience with you, because I had the same problem and spent a lot of time on it.

Put your WebView in RelativeLayout and not in FrameLayout.

What I have tested: My WebView's onPageFinished() was called every time, but on the screen I got blank page.

From chrome://inspectWebView debugger I was able to "ping" my WebView by pressing inspect button, and after that WebView was refreshing immediately.

My thoughts - WebView isn't rendered correctly in FrameLayout, and RelativeLayout fixes the issue (even invalidate() and requestLayout() calls didn't help).

Solution 3:

I think if you edit some of your code then it will be ok.Look how i do it in my case below.Try for you in this way.. For displaying a web page

finalWebViewwbView= (WebView) findViewById(R.id.WebView);

WebSettingssettings= wbView.getSettings();
settings.setJavaScriptEnabled(true); 
wbView.loadUrl("https://play.google.com/store/apps");
wbView.clearView();
wbView.measure(100, 100);
settings.setUseWideViewPort(true);
settings.setLoadWithOverviewMode(true);

For showing HTML: See this tutorial..

Solution 4:

instead of passing null, you should pass an empty String to it. ex: "" So you should call it like this: wview.loadDataWithBaseURL("", "<HTML><BODY><H3>Test</H3></BODY></HTML>","text/html","utf-8","");

Solution 5:

I gave +1 because these were both valid assistance to getting the webview to working properly, but it was not the solution to my issue.

What I didn't realize is I had a wrap_content on the include of my webview layout and this caused it to have a height of 0px. By setting this to fill_parent I resolved the issue. (Webview with white background and app with white background you cant really tell its not full height when it shows up as full height in the layout designer.)

Thanks for your help though!
