Background of the ScrollView causes apps crash

I struggle to create a reading app with a UI background. The point is that my background needs to be scrollable as well as the text. So I've decided just to put in my app a large jpg with the size of my scroll (992x10901px). The app just doesn't want to start like this.

Btw, at least I see the background in the Design View if I specify the size in px. In dp it isn't displayed.

enter image description here

Please, give me some advice, how to proceed.

My xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"

android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.android.scrollingtext.MainActivity">

<TextView
    android:id="@+id/article_heading"
