AccountKIt LoginActivity Background Image doesn't show up
<p>I started implementing AccountKit SDK by Facebook in my application.
In the UI documentation it clearly gives me attribute for the background Image of the theme, but that doesn't work.</p>

<p><a href="https://developers.facebook.com/docs/accountkit/android/customizing" rel="nofollow">https://developers.facebook.com/docs/accountkit/android/customizing</a></p>

<p>Then I tried it with small 100x100 image
which worked.
Any solution why normal Image won't show up as a background
here's my code</p>

<pre><code>  &lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;resources&gt;

&lt;style name="LoginThemeYellow" parent="Theme.AccountKit"&gt;
    &lt;item name="com_accountkit_primary_color"&gt;#94612D&lt;/item&gt;
    &lt;item name="com_accountkit_primary_text_color"&gt;@android:color/white&lt;/item&gt;
    &lt;item name="com_accountkit_secondary_text_color"&gt;#BE8C5B&lt;/item&gt;
    &lt;item name="com_accountkit_secondary_color"&gt;@android:color/transparent&lt;/item&gt;
    &lt;item name="com_accountkit_status_bar_color"&gt;#94612D&lt;/item&gt;
    &lt;item name="com_accountkit_button_background_color"&gt;#94612D&lt;/item&gt;
    &lt;item name="com_accountkit_button_border_color"&gt;#94612D&lt;/item&gt;
    &lt;item name="com_accountkit_button_disabled_background_color"&gt;#e2b382&lt;/item&gt;
    &lt;item name="com_accountkit_background"&gt;@mipmap/horse1&lt;/item&gt;

    &lt;item name="com_accountkit_input_accent_color"&gt;?attr/com_accountkit_primary_color&lt;/item&gt;
    &lt;item name="com_accountkit_input_border_color"&gt;?attr/com_accountkit_primary_color&lt;/item&gt;
&lt;/style&gt;
&lt;/resources&gt;
