Solution 1
Take a look at Apply a theme to an Activity or application to apply the background image across the whole application.
Solution 2
Add android:windowBackground
to your theme:
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<item name="android:windowBackground">@color/colorPrimaryDark</item>
</style>
And of course make sure your manifest uses the theme for you application:
<?xml version="1.0" encoding="utf-8"?>
<manifest package="com.package.name"
xmlns:android="http://schemas.android.com/apk/res/android">
<application
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
</application>
</manifest>

In my application I have a lot of layers and instead of setting a background image to each of them, I want to set a background once and for all. How can I do that?

lomza about 13 yearsThank You! So, basically, I define a style with a background image, then in Manifest I put "android:theme" tag with my style and that's all?

Rajath about 13 yearsI haven't tried it for the case of a background image, but yes, that's the direction you need to take.

lomza about 13 yearsIt works! Though, I have few more problems, like implementing few themes in one activity/application, but I hope I'll handle it.
