**Description**  
I implemented 2 SDKs: Meeting and Video SDK

**Which Android Meeting SDK version?**  
Meeting: zoom-sdk-android-5.10.3.5614  
Video: zoom-video-sdk-android-1.3.0

**To Reproduce(If applicable)**  
Steps to reproduce the behavior:

1. Create 3 modules
2. Implement 3 zoom modules (common lib, mobilertc, videosdk) to 1 module
3. Build
4. See errors

Hi @Henry.Ng, thanks for using the dev forum.

The error you are seeing is being caused by including both the Meeting SDK and Video SDK in the same project. These two SDKs have some shared components, so it is not possible to integrate both of them into the same project.

Thanks!

Which SDK should I use for both Meeting and Video SDK?

For some functions, we are using Meeting SDK  
Remaining functions we are using Video SDK

I have 2 accounts:  
The first account is used for meeting SDK  
The second account is used for video SDK.

Thanks

Hi @Henry.Ng,

As mentioned previously, you cannot use both SDKs in the same project. You will need to consolidate your functionality in such a way that only one of the SDKs is being used. If you are unsure which SDK best fits your needs, there is a comparison available [here](https://marketplace.zoom.us/docs/sdk/overview/compare).

Thanks!

Hi @jon.zoom ,

My co-worker is working on the ios + web sides, he can implement both SDKs. so is it only happening on the Android side?

Hi @Henry.Ng,

Due to differences in build environments, the behavior will vary between platforms. Ultimately, the Meeting SDK and Video SDK were not built with the intent of both being used in the same project.

Thanks!

Hi @jon.zoom , My company paid for both SDKs, so Can you send us customized SDKs using both the Video and Meeting functions?

If you can do that, I will send the company information to you.  
Thanks.

Or at least, Zoom center can give me a guide that helps me build an AAR file for both SDKs(meeting and video). Thanks
