Android WebView - Page loads only on old devices (4.1.2)

I'm working on a Project, which loads a Webview within native Apps.

The App contains a WebView, which is only loading correctly on old Android Devices (4.1.2). On a new Version (4.4. and higher), the View stays blank.

I tried already to set the mixed content:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    getSettings().setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);
}

But it wont change anything. Same with the handler.proceed() function.

 @Override
public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
    handler.proceed(); // Ignore SSL certificate errors
}

The Website contains a lot of JavaScript, so i tried also different Settings like setDomStorageEnabled and so on... Actually the Environment is a test-server, so the Certificates are created on our own. So I just want to test the app and dont think about publishing and the probably issues. But I don't get an error in logcat, so I really don't know, what else could be wrong and how investigate further.

Solution

  • I can recommend you to debug your newer devices.
    Here you have a nice sample. You will be able to debug all request and responses and even look through all of that fantastic JS stuff:)
