Hello, support team. I try to implement zoom android stack. But it’s build fails because “protobuf-java-2.4.1.jar” which is included in mobilertc.aar conflicts with “com.google.protobuf:protobuf-lite:3.0.1”. We are using “com.google.protobuf:protobuf-lite:3.0.1” for google speech api. And our environment is Android Studio 3.0.1 with Gradle 3.1. How can I deal with this? Best, Junya \*\*\*\*\* stack trace is here \*\*\*\*\* org.gradle.api.tasks.TaskExecutionException: Execution failed for task ‘:polyglotsAndroid:transformClassesWithMultidexlistForDebug’. at

Now, Zoom Android SDK is using protobuf 2.4.1 lite version. This issue can not been resolved based on current SDK version. We are working to not use protobuf in our future Android SDK. ---

Hi, any update on this. I can see you still have protobuf 2.4.1 lite in the sdk? ---

Hi [stntz](https://devforum.zoom.us/u/stntz), Thanks for the reply. We have fixed this in our SDK so it won’t have conflicts anymore. Thanks! ---
