Android Webview access denied

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.

Targetting Android S+ will require you to provide file access permission if the html file is accessed from the device storage. Just add the line below:

webview.getSettings().setAllowFileAccess(true);

This resolved the mentioned error for me.

Uninstall application first and reinstall after inserting permission

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

Do not just restart.

Uninstall the application from the emulator or phone completely and compile or install again. It should already work.

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.

This is broke in the latest "Q Android 10", change target frame work to "Pie- Android 9" which will work. Change by going to

File > Project Structure

Then on left > Modules > Compiler SK Version (change to Api 28)

Note: Install Android PIE if it not already or the option does not appear by going to Preferences then > System Preference > Android SDK on left

Might be SSL cert throwing error, try this:

// Ignoring SSL certificate errors

@Override
public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError er) {
   handler.proceed();
}

You can try building your app with Android Smart WebView framework, it can provide you more insight on what might be going on with your webpage.
