Android WebView shows a blank page

Question

Trying to create a WebView but it only shows a blank/white page. I have followed several examples and they all say that work with this code...

Here is my code:

import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;

public class PostenWebView extends Activity {

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.web_view);
        WebView webview = (WebView)findViewById(R.id.webview);
        webview.loadUrl("http://www.google.com");
    }
}

And here is the web_view.xml:

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

Answer 1

You have to add the permission to your AndroidManifest.xml file.

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

Answer 2

You need to enable Javascript (.getSettings().setJavaScriptEnabled(true)), or choose a Web page that does not rely upon Javascript.

Answer 3

I found an example that finally worked! :)

http://code.google.com/p/apps-for-android/source/browse/trunk/Samples/WebViewDemo/src/com/google/android/webviewdemo/WebViewDemo.java

But the problem was also with the URL, when I tried to go to google.com through my WebView in instantly opened my ordinary browser on my phone... But other URL's worked just fine :)

Answer 4

I don't know about other phones, but on HTC HERO i have similar problem: after i disable mobile internet and enable wifi, webview doesn't display, although other internet activities like httpget in the same application work without any problems. No errors are shown in the logs...
