I'm trying to incorporate Amazon's Mobile Ads but keep running into an issue where Android Studio says:
Rendering Problems
The following classes could not be instantiated:
- com.amazon.device.ads.AdLayout(Open Class, Show Exception)
Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE
When clicking 'Show Exception':

I'm trying to follow the steps outlined on https://developer.amazon.com/public/apis/earn/mobile-ads/docs/quick-start, but they don't include them for Android Studios.
As for my project: - I have amazon-ads-5.1.153.jar in my project's libs folder, and have it added as a library.
Within the project Structure, I have the library added to my main Module, checked for Export.
Added the line to my manifest:
And within my build.gradle, I have added in:
dependencies { compile files('libs/amazon-ads-5.1.153.jar') }
And the view was copy-pasted from one of their examples:
<com.amazon.device.ads.AdLayout
android:id="@+id/adView"
android:layout_width="320dp"
android:layout_height="50dp"
Amazon:adSize="320x50"/>
