Why Data Can not Pass to Second Activity - xamarin.android

Question

Using XamarinStudio and below code base on the Sample in the tutorial. Here the questions.
Do I need to generate the AndroidManifest from the Project Option> Android Application when testing the App ?
Why there is no data passing over even I have generated an AndroidManifest , the code :
---Activity 1
[Activity (Label = "HelloMultiScreen", MainLauncher = true,Icon = "#drawable/icon")]
public class FirstActivity : Activity
{
int count = 1;
protected override void OnCreate (Bundle bundle)
{
base.OnCreate (bundle);
//Use UI created in Main.axml
SetContentView (Resource.Layout.Main);
var showSecond = FindViewById (Resource.Id.showSecond);
showSecond.Click += (sender, e) => {
var second = new Intent(this, typeof(SecondActivity));
second.PutExtra("FirstData", "Data from FirstActivity");
StartActivity (typeof(SecondActivity));
};
}
}
---Activity 2
[Activity (Label = "SecondActivity")]
public class SecondActivity : Activity
{
protected override void OnCreate (Bundle bundle)
{
base.OnCreate (bundle);
// Create your application here
SetContentView (Resource.Layout.Second);
var label = FindViewById (Resource.Id.screen2Label);
label.Text = Intent.GetStringExtra("FirstData") ?? "Data not available";
}
}
Thanks

Ok I found the problem when I remade the project myself.
The problem lies in this piece of code:
var second = new Intent(this, typeof(SecondActivity));
second.PutExtra("FirstData", "Data from FirstActivity");
StartActivity (typeof(SecondActivity));
What happens is that you make an Intent with the right data. But you start a new activity without that data.
To fix it change the code to this:
var second = new Intent(this, typeof(SecondActivity));
second.PutExtra("FirstData", "Data from FirstActivity");
StartActivity(second);`
