I'm starting to use Xamarin and I already saw tutorials and looked over the internet for a specific answer to this question, but with no lucky.
Here's the question.
When I create a new project with VisualStudio choosing a Xamarin C# Android application, it automatically creates a MainActivity.cs with this code:
Note this code:
protected override void OnCreate(Bundle bundle)
and
base.OnCreate(bundle);
Then I added a new activity (right click on the project, Add, New item, Activity, Add) called Activity1.cs, but here in the new activity the code automatically generated by Xamarin is different:
Note:
protected override void OnCreate(Bundle savedInstanceState)
and
base.OnCreate(savedInstanceState);
Why is "bundle" replaced by "savedInstanceState"? What does change if I put "bundle" in Activity1 or vice-versa?
Thanks a lot to anyone can help me, and sorry if it seems a silly question.
bundle
and savedInstanceState
are just names of the parameter so there is no difference between them. In C# parameter names does not matter.
Here is a description of the parameter from Xamarin documentation that is passed to OnCreate
method:
If the activity is being re-initialized after previously being shut down then this Bundle contains the data it most recently supplied in Activity.OnSaveInstanceState(Bundle). Note: Otherwise it is null.
