Ok i found it out now but now I am stuck on the 4th :-(

import android.os.Bundle;
import android.content.Intent;
import android.net.Uri;
import android.webkit.WebView;

public class WebViewActivity extends Activity {

    protected String mUrl;

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

        WebView webView = (WebView) findViewById(R.id.webView1);
        Intent intent = getIntent();
        Uri blogUri = intent.getData();
        mUrl.loadUrl(blogUri.toString());

Your last line is trying to call the 'loadUrl' method from the mUrl variable, which is not correct. The mUrl variable should just be holding the blogUri as a String object (i.e. mUrl = <code to convert blogUri to a String>;).

Then, with that in place, you need to load the URL in the webView (hint: that 'loadUrl' method you are trying to call is actually from the WebView class). :)

I am sorry I still get an error;

import android.os.Bundle;
import android.content.Intent;
import android.net.Uri;
import android.webkit.WebView;

public class WebViewActivity extends Activity {

    protected String mUrl;

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

        WebView webView = (WebView) findViewById(R.id.webView1);
                 Intent intent = getIntent();
                 mUrl= intent.getData().toString(); }
        webView.loadUrl(blogUri.toString());

This is close! You still want the line you had earlier:

Uri blogUri = intent.getData();

Then set mUrl to the String version of the blogUri variable (like you're trying to do for loadUrl).

Then use your webView.loadUrl() method, but pass in the mUrl variable instead of what you have there.

This code looks like it might work except you need to move that last line before the closing curly brace on the mUrl line above it.

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

        WebView webView = (WebView) findViewById(R.id.webView1);
                 Intent intent = getIntent();
                 mUrl= intent.getData().toString(); }
         WebView.loadUrl("http://www.teamtreehouse.com", "http://developer.android.com", "http://www.github.com");

So with this one, you're good up through setting blogUri. Your next step should be to set mUrl using blogUri. So on the line after that you would have mUrl = blogUri.toString();

Now, mUrl is a String variable holding the correct String representation of the URL we want. So all you need is to use the loadUrl method on the webView variable (note the lowercase "w") and pass in mUrl as a parameter. The loadUrl() method expects a String parameter.

Hooray!! I'm so glad you got past it. I never want to just give you the code for these, so hopefully working through it helps your learning in some way! :)
