Unhandled exception in xamarin forms app after setting SetContentView - xamarin

Question

I need to place my app icon on the left side of the toolbar, so I placed an ImageButton in Toolbar.axml. I set the SetContentView so that I can access the ImageButton using FindViewById and Listen to the click event.
But After adding the SetContentView line my app throws UnhandledException.
Below is my Main.axml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:popupTheme="#style/ThemeOverlay.AppCompat.Light">
<ImageButton
android:src="#drawable/appicon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:id="#+id/homeicon" />
</android.support.v7.widget.Toolbar>
</LinearLayout>
And my MainActivity.cs is like below:
[Activity(Label = "XamarinToolBar", Icon = "#drawable/icon", Theme =
"#style/MainTheme", MainLauncher = true, ConfigurationChanges =
ConfigChanges.ScreenSize | ConfigChanges.Orientation)]
public class MainActivity :
global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
{
protected override void OnCreate(Bundle bundle)
{
//TabLayoutResource = Resource.Layout.Tabbar;
//ToolbarResource = Resource.Layout.Toolbar;
base.OnCreate(bundle);
SetContentView(Resource.Layout.Main);
ImageButton homeButton = (ImageButton)FindViewById<ImageButton>(Resource.Id.homeicon);
homeButton.Click += HomeButton_Click;
global::Xamarin.Forms.Forms.Init(this, bundle);
LoadApplication(new App());
}
private void HomeButton_Click(object sender, EventArgs e)
{
}
}

Answer 1

The Problem is here :
public class MainActivity :
global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
You are mixing up the xamarin forms FormsAppCompatActivity with your AppCompactActivity and remove these two lines from your cs file
global::Xamarin.Forms.Forms.Init(this, bundle);
LoadApplication(new App());
I hope it helps
Goodluck!

i think you are trying to mix and match the xamarin.forms "FormsAppCompatActivity" and make it behave like a normal android Activity in which shouldn't be the case because xamarin.forms "FormsAppCompatActivity" has its own underlying rendering engine through the use of xaml pages (e.g. ContentPage, MasterDetailPage etc.). Try to create an Android project instead.
