We instantiate Xamarin Forms within each supported platform of the app. Xamarin Forms support the following platforms:
Android
iOS
Windows Phone
Typically, an activity to start an activity class looks like this:
public class MyActivity : Activity
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// then whatever you need to doTo start a Xamarin Forms app, this changes as we are not inheriting the Activity but a FormsApplicationActivity, or more precisely:
public class MyActivity : global::Xamarin.Forms.Platform.Android.FormsApplicationActivity
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
global::Xamarin.Forms.Forms.Init(this, bundle);
LoadApplication(new App());
}
}
