<h2 dir="auto">Steps to Reproduce</h2>
<p dir="auto">I start a SimpleDialog with a list in it . When I start the Dialog on the phone all is fine. In the emulator I get an exception which does not provide info to get to the root cause or useable information. (for me ;))<br>
Phone and Emulator:<br>
• Android SDK built for x86 • emulator-5554    • android-x86 • Android 7.1.1 (API 25) (emulator)<br>
• Moto G 5 Plus             • ZY224DHFWG       • android-arm • Android 7.0 (API 24)</p>
<p dir="auto">After simplifying the code I could  reproduce the behavior with this simple code.<br>
The error shows up  on the emulator only it renders fine on my phone (Moto G5plus and Pixel). Also using shrinkWrap does not make a difference:</p>
<p dir="auto">I also checked these other defects bt it seems the error message is still not helping to get to the problem and I dont know why I actually need any height setting in the code snippet below.</p>
<p dir="auto">These are the related defects:<br>
