Android Webview access denied

Question

On Android 9 (Api 29) am trying to load a url and i get the error "The webpage at url could not be loaded because: net::ERR_ACCESS_DENIED".

I have internet the internet permission in the AndroidManifest.xml files

<uses-permission android:name="android.permission.INTERNET" />

From logcat, i can see the the following error as well :

E/chromium: [ERROR:socket_posix.cc(94)] CreatePlatformSocket() failed: Operation not permitted (1)

My code is as follows :

WebView webView = findViewById(R.id.webView);
webView.loadUrl("https://andela.com/alc/");

I later added the following code to get more detail :

webView.setWebViewClient(new WebViewClient(){
    @Override
    public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {
        super.onReceivedError(view, request, error);
        Log.d("TAG", error.getDescription().toString());
        // handler.proceed(); This line wont make a different on API 29, Webview still bank
    }
});

The Webview loads the url properly when using an emulator running API 25. Also tested on API 28 and it works fine. Only doesn't work on API 29.

Answer 1

just uninstall the app and once again install it.That work 100%

Answer 2

In my case the web page becomes loading correctly (without ERR_ACCESS_DENIED) after changing applicationId in build.gradle (and run the app, of-course). After that you may return the old applicationId.
