Android WebView加载最基本的代码

public class WebViewActivity extends Activity {
    @BindView(R.id.webview)
    WebView mWebView;
    private String url;

     @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.webview);
        initInjecter();
    }

    @SuppressLint({"SetJavaScriptEnabled"})
    protected void initInjecter() {
        url = getIntent().getStringExtra("url");
        initweb();
    }

    private void initweb() {
        mWebView.getSettings().setDefaultTextEncodingName("UTF-8");
        mWebView.setWebViewClient(new InnerWebViewClient());
        mWebView.getSettings().setUseWideViewPort(true);
        mWebView.getSettings().setLoadWithOverviewMode(true);
        mWebView.getSettings().setJavaScriptEnabled(true);
        mWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
        mWebView.getSettings().setSupportZoom(true);
        mWebView.getSettings().setAppCacheEnabled(true);
        mWebView.getSettings().setDatabaseEnabled(true);
        mWebView.getSettings().setDomStorageEnabled(true);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
            mWebView.getSettings().setMediaPlaybackRequiresUserGesture(false);
        }

        mWebView.setWebChromeClient(new WebChromeClient() {
            @Override
            public void onProgressChanged(WebView view, int newProgress) {
                super.onProgressChanged(view, newProgress);
            }
        });

        mWebView.loadUrl(url);

        mWebView.setWebViewClient(new WebViewClient(){

            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);

                return true;
            }

    }

    private class InnerWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);//加载下一个Html页面
            return true;
        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
        }
    }

    @Override
    public void onBackPressed() {
        if ( mWebView.canGoBack()) {
            mWebView.goBack();// 返回HTML前一个页面
            return;
        }
        super.onBackPressed();
    }

    @Override
    protected void onPause() {
        super.onPause();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
            mWebView.onPause();
        }
    }
    @Override
    protected void onResume() {
        super.onResume();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
            mWebView.onResume();
        }
    }
    @Override
    protected void onDestroy() {

        mWebView.resumeTimers();
        mWebView.destroy();
