android – WebView没有加载网页

我正在使用WebView加载网站.但是,当加载特定网站时,这是非常慢的漏洞.

我正在使用以下代码加载WebView.

@Override
    protected void onNewIntent(Intent intent) {
        if (intent.getStringExtra("url") != null) {
            webView.loadurl(intent.getStringExtra("url"));

            }
    }

但我正在调用webView.loadUrl(Config.URL); (Config.URL可能包含与上述相同的url)在onCreate()方法中初始化以后的WebView.

this.webView = (WebView) findViewById(R.id.wv);
        this.webView.getSettings().setJavaScriptEnabled(true);
        this.webView.getSettings().setLoadsImagesAutomatically(true);
        this.webView.getSettings().setDomStorageEnabled(true);
        this.webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
        MyClient client = new MyClient(WebActivity.this, (ProgressBar)findViewById(R.id.progressBar));
        webView.setWebViewClient(client);

Loading a from onCreate() is working fine (not fine, it’s too slow). But

the same URL that is loading from onNewIntent() is not working!!! .

After I did this in onNewIntent() no URLs got loaded using

webView.loadurl() and the current page is getting immovable. ie. the

scrollbars are moving in WebView but page is not scrolling. I tested

the same URL in onCreate() and it is working.

为了做到这一点,我正在传递url

intent.putExtra("url", Config.URL+targetUrl);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);

与通知的待决意图.虽然它在某些设备(即Google Nexus)中正在运行.但是大多数手机都不行.

我有

android:hardwareAccelerated="true"

Myclient

public class MyClient extends WebViewClient{
    private Context context;
    private Activity activity;
    private Handler handler;
    private Runnable runnable;
    private ProgressBar viewBar;

    public void setFirstLoad(boolean firstLoad) {
        this.firstLoad = firstLoad;
    }

    private boolean firstLoad=false;
    public MyClient(Activity activity, ProgressBar bar) {
        this.context = activity.getApplicationContext();
        this.activity = activity;
        viewBar=bar;
        handler=new Handler();
    }

    @Override

        /*if (url.startsWith("tel:")) {

            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

        }else if(url.startsWith("http:") || url.startsWith("https:")) {

        return true;*/
        if (Uri.parse(url).getHost().equals("www.somepage.com")) {
            return false;
        }
        // Otherwise, the link is not for a page on my site, so launch another Activity that handles URLs
        try {
            Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));

            Answers.getInstance().logShare(new ShareEvent()
            .putContentId(Build.USER)
            .putMethod(shareName(url))
            .putContentName(contentDecode(url))
            .putContentType("news_share"));
        }catch (android.content.ActivityNotFoundException e){
            Log.e("Activity not found",e.toString());
            Toast.makeText(context,"Application not found",Toast.LENGTH_LONG).show();
        }

        return true;

    }

    @Override
    public void onReceivedError(final WebView view, int errorCode, String description, final String failingUrl) {
        //Clearing the WebView
        try {
            view.stopLoading();
        } catch (Exception e) {
        }
        try {

        AlertDialog alert = alertDialog.create();
        alert.show();

    @Override

        super.onLoadResource(view, url);
        //injectScriptFile(view, "js/script.js");
        injectCSS(view,"css/style.css");
        if (firstLoad){
            firstLoad=false;
            view.setVisibility(View.INVISIBLE);
            viewBar.setVisibility(View.VISIBLE);
            runnable=new Runnable() {
                @Override
                public void run() {
                    viewBar.setVisibility(View.GONE);
                    view.setVisibility(View.VISIBLE);
                }
            };
            handler.postDelayed(runnable,2000);
        }

        // test if the script was loaded
       // view.loadUrl("javascript:setTimeout(hideMe(), 200)");
    }

    /*@Override
    public void onPageFinished(final WebView view, String url) {

        //System.gc();
    }*/


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

问题是：在onNewIntent()中使用loadurl()方法时有什么问题？
