**Description**
I have followed the integration steps as per your docs but I am facing java.lang.UnsatisfiedLinkError crash randomly. I have tried using zoom SDK version 5.4.3.603 and 5.2.42043.1112, app is crashing in both versions. I have tried a lot to solve it but unable to do so. I have tried abiFilters as well but it does not make any difference. Hoping to hear from you soon.

**To Reproduce(If applicable)**
Steps to reproduce the behavior:
Initialize the SDK.
**Smartphone (please complete the following information):**

Hi @ahmed2, thanks for the post.
Sorry to hear you are running into a crash with the SDK. Can you please provide the full stack trace from the crash so that I can take a look at how we can resolve this?
Thanks!

Thanks for the reply @jon.zoom.

Hi @ahmed2, thanks for the additional info.
Can you please confirm that you are correctly importing both the `mobilertc.aar` and `commonlib.aar` modules into your project according to the steps outlined [here](https://marketplace.zoom.us/docs/sdk/native-sdks/android/getting-started/integration)? If these steps are followed, you should also see two lines in your `build.gradle` file’s `dependencies` block for these modules.
Thanks!

Yes @jon.zoom, I have followed the steps as they are described in the docs and imported both the modules mobilertc.aar and commonlib.aar. Also I have made sure that my gradle build file consists implementation project(’:commonlib’), implementation project(’:mobilertc’). And my settings.gradle file also consists include ‘:mobilertc’, include ‘:commonlib’. Still I am having that crash randomly while zoom initialization.

Hi @ahmed2, thanks for confirming that.
Can you please try updating to the most recent version of our SDK? Let me know if the issue still persists on that version.
Thanks!

@ahmed2 The sdk only support ‘armeabi-v7a x86 arm64-v8a x86\_64’ cpu architecture.
If you project have native module,you can add `ndk { abiFilters 'armeabi-v7a x86 arm64-v8a x86_64' }` in the build.gradle
