Hi @shingshing6, thanks for the post.

I’m sorry, but I do not see anything indicating that the SDK is involved in this stack trace. Please let me know if I am missing something and I will be happy to help.

Thanks!

Hi @jon.zoom

I have no idea too. Previously i use SDK 5.4.3.613 and it works fine. After i use the new SDK, it caused this error.

I only replaced commonlib and mobiletrc folder with latest SDK in my project.

Thanks

Hi @shingshing6,

Since the SDK is not mentioned in the stack trace, we will not be able to assist further. Let me know if you find any new information indicating that the SDK is involved.

Thanks!

Hi @shingshing6,

I am still not seeing any mentions of our SDK in these errors. As a reminder, we can only provide assistance with issues directly related to our SDK.

Thanks!

Hi @jon.zoom

The above error metioned mobilertc, it is not related to Zoom SDK?

@shingshing6 Were you able to find solution for the bug above, for which you shared error log? I have very similar problem related to exoplayer

Hi @shingshing6,

Yes, `mobilertc` is one of the two SDK modules. However, your previous reply did not contain any mentions of the `mobilertc` module. Instead, a couple of the errors contained `zoommobilertc`. Did you rename the `mobilertc` module in your project at some point after installing the SDK to `zoommobilertc`?

Thanks!

Hi @osumeja27,

This forum is only meant to assist with issues directly related to the Zoom Meeting SDK. If you need general assistance with an error unrelated to our SDK, please visit [StackOverflow](https://stackoverflow.com/) or a similar alternative. 🙂

Thanks!

hi @jon.zoom

Yes, i have renamed it before. However, it is the same case if i use the default name of the SDK. Any suggestions?

Thanks.

Hi @shingshing6,

The name of your mobilertc and commonlib modules should not matter, as long as they are being properly added to your project’s dependencies.

When you updated from the previous version of the SDK, did you update both the `mobilertc.aar` and `commonlib.aar` files in your project? If you are unsure, you can try removing these from your project entirely and adding the back in as if you were integrating them for the first time.

Thanks!

Hi @shingshing6,

Thanks for confirming. Can you please provide your `mobilertc/build.gradle` file’s contents so that we can verify all of the required dependencies are properly setup?

Thanks!

Hi @jon.zoom

The mobilertc/build.gradle as below:

> configurations.maybeCreate(“default”)  
> artifacts.add(“default”, file(‘mobilertc.aar’))

While in app/build.gradle i put this

> implementation ‘androidx.security:security-crypto:1.1.0-alpha02’  
> implementation ‘com.google.crypto.tink:tink-android:1.5.0’  
> implementation ‘com.google.android.exoplayer:exoplayer-core:2.11.4’

> implementation ‘com.github.bumptech.glide:annotations:4.12.0’

> implementation ‘androidx.appcompat:appcompat:1.3.0’

Some versions are changed due to my project need.

Hi @shingshing6,

There very well may be issues associated with not using the same version as the SDK. Can you please try changing the versions you are using to match what is in the sample app to see if the same issue is present?

Thanks!
