### Before Creating a New Topic:

**Description**  
Hi Team,

we have two different webrtc files inside our application. One is from the zoom and one is from the Mizu voip. When we try to create a signed apk, android studio is throwing error stating that Type a.a is defined multiple times. We also enabled mutli dex, still it is throwing error.

**Which Android Video SDK version?**  
we are using latest version, 1.5.0

**Additional context**  
Below is the error:

Type a.a is defined multiple times: /Users/deviprasadmanohargamangatti/Projects/Learning Project/Akorbi/android/mobilertc/build/.transforms/e489a86bb0b78227507a1a9dccb84dcc/transformed/jetified-mobilertc-runtime/classes.dex, /Users/deviprasadmanohargamangatti/Projects/Learning Project/Akorbi/android/AJVoIP/build/.transforms/6b1374d9519771a246a02472f2435f2a/transformed/jetified-AJVoIP-runtime/classes.dex
