Can someone help me with Task three of this code challenge please.
The Task is : Now get the URI that you passed in as the data for the Intent. Convert it to a String URL and store it in the 'mUrl' member variable.
my code so far is:
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();
WebView webView = (WebView) findViewById (R.id.webView1);
webView.loadUrl(blogUri.toString());
}
}

I believe you were at:

The challenge that comes after this video is a little different from the video. (Which is good... it get's you to think)
You need to read the question they give you carefully.
"Now get the URI that you passed in as the data for the Intent. Convert it to a String URL and store it in the 'mUrl' member variable."
They never tell you to create a new variable (which you do), but actually to place the data as a string into the mUrl variable.
This code passes challenge number 3.
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);
// Add code here!
Intent intent = getIntent();
mUrl = intent.getData().toString();
}
}
Additionally, in challenge three it never asks you to declare a webView, and it never asks you to load the Url. Look at the code you pasted in your question. You have this typed twice:
WebView webView = (WebView) findViewById (R.id.webView1);
Which is not required at all. Especially in part three.
Keep coding!
