I have an error on inflating the fragment into a layout. The IDE I am working with is Xamarin, which is a android developing tool in the programming language C#.
I get the error on the classwhich is in this directory
JeugdbewegingApp\JeugdbewegingApp\Presentation\MainMenu.cs
In the following piece of code the error is thrown by the fragment class name. This code is from the NewsFeed.axml layout file.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button
android:id="@+id/myButton"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="test" />
<TextView
android:text="Text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/textView1" />
<fragment
class="jeugdbewegingApp/jeugdbewegingApp/presentation/MainMenu"
android:id="@+id/menu_fragment"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
I am aware of the namespace that needs to be written in lowercase but does your files and directories need to be in lowercase to?
I've been stuck for quite a while now and can't find a solution, the tutorial I am using is http://docs.xamarin.com/guides/android/platform_features/fragments/part_1_-_creating_a_fragment/
The full error is this
