A very simple full-screen WebView activity for Android native wrappers, as a starting point.

MainActivity.java

package com.willowtreeapps.demo;

import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.Window;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends Activity {
    private WebView mWebView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().requestFeature(Window.FEATURE_NO_TITLE);
        mWebView = new WebView(this);
        mWebView.loadUrl("http://m.willowtreeapps.com/");
        mWebView.setWebViewClient(new WebViewClient() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);
                return true;
            }
        });

        this.setContentView(mWebView);
    }

    @Override
    public boolean onKeyDown(final int keyCode, final KeyEvent event) {
        if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
            mWebView.goBack();
            return true;
        }
        return super.onKeyDown(keyCode, event);
    }
}

Great starting point, thanks a lot for the gist! :)

This is just a starting point but it is worth noting that WebViewClient.boolean shouldOverrideUrlLoading (WebView, String) was deprecated at API level 24. The documentation for the alternative method, shouldOverrideUrlLoading (WebView, WebResourceRequest) says this:

This method is also called for subframes with non-http schemes, thus it is strongly disadvised to unconditionally call loadUrl(String) with the request's url from inside the method and then return true, as this will make WebView to attempt loading a non-http url, and thus fail.

Is this similar to using Chrome in terms of performance? I followed another tutorial and it works, but it's extremely slow compared to using Chrome directly.

This was really helpful, thanks! I'd definitely enable Javascript in the main Gist, though:

WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);

Many users, including web or application developers, are confronting the err_cache_miss consistently in Google Chrome browser.
