I have this in my Main.axml;
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
>
<Button
android:id="@+id/MyButton"
android:layout_width="200dp"
android:layout_height="wrap_content"
android:text="@string/Hello"/>
<ImageView
android:src="@drawable/samplebackground"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/MyButton"/>
</RelativeLayout>
It builds fine and sampleBackground is a jpg that has been included in my project.
However when I try to deploy I get an error;
Object reference not set to an instance of an object
And there are a bunch of lines stating <filename unknown>
If I remove the ImageView from the markup the application deploys fine.
Any thoughts?
