Hi [zhpszoom](https://devforum.zoom.us/u/zhpszoom),

Thanks for using Zoom SDK. Based on the error code shown, it seems like there are invalid parameters passing to the SDK initialization methods. Please follow the instruction: [https://marketplace.zoom.us/docs/sdk/native-sdks/android/mastering-zoom-sdk/sdk-initialization](https://marketplace.zoom.us/docs/sdk/native-sdks/android/mastering-zoom-sdk/sdk-initialization) or refer to the implementation in our demo: [https://github.com/zoom/zoom-sdk-android/blob/master/mobilertc-android-studio/sample/src/main/java/us/zoom/sdksample/initsdk/InitAuthSDKHelper.java](https://github.com/zoom/zoom-sdk-android/blob/master/mobilertc-android-studio/sample/src/main/java/us/zoom/sdksample/initsdk/InitAuthSDKHelper.java) to see if it helps the question.

Hope this helps. Thanks!
