android - WebView 和 shouldOverrideUrlLoading

Question

我的代码:

    public class View_WebView extends Activity  {
    WebView myWebView;

    private class MyWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if (url.endsWith(".mp4")){
            Intent in = new Intent (Intent.ACTION_VIEW , Uri.parse(url));
            startActivity(in);
            return true;
        }
        else
            return false;
        }
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        myWebView = (WebView) findViewById(R.id.webview);
        myWebView.setWebViewClient(new WebViewClient());      
        myWebView.loadUrl("http://hdcast.pl");
    }     

}


    <?xml version="1.0" encoding="utf-8"?>
<WebView  xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/webview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
 />

Eclipse 编译正确，当我在智能手机上启动我的应用程序时出现错误:

“很遗憾，应用XX已经停止”

直接做:

从这里tutorial

myWebView.setWebViewClient(new WebViewClient() {  
@Override  
public boolean shouldOverrideUrlLoading(WebView view, String url) {  
 if (url.endsWith(".mp4")){
    Intent in = new Intent (Intent.ACTION_VIEW , Uri.parse(url));
    startActivity(in);
    return true;
}
else
    return false;
}
