I cannot initialize Zoom SDK. I’m getting “errorCode: 3, internalErrorCode: 100006000” I don’t know which version. I assume its the latest since I downloaded from official website. My code is this ![Capture](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/1/1311e11f9d13441b4b8caaceeddde08c90721975.png) Strange thing I ran a couple of times successfully but now it doesnt work. Also, it works on emulator but not on device. ---

Hi Tony, Thanks for using Zoom SDK. Based on the error code, it says the SDK cannot resolve the host thus and the request hasn’t received any response from the server. 1. Please double check whether your web-domain is set to be “[zoom.us](http://zoom.us/)”. Or you might need to consult the person who provides this demo to you if they have any special configurations on the web-domain. 2. Are you using any kind of proxy? Hope this helps. Thanks! ---

Hi zhurm, Thanks for using Zoom SDK. Regarding your questions: - The error code you got “error code=3 ex code=100007000” indicates that our SDK couldn’t connect to the server or proxy. Please double check the web domain you pass to the SDK, or please verify whether you are using any kind of proxy or have unusual network settings. - For Android SDK integration, you can refer to the doc: [https://marketplace.zoom.us/docs/sdk/native-sdks/android/getting-started/integration](https://marketplace.zoom.us/docs/sdk/native-sdks/android/getting-started/integration), and you can also refer to the configurations in our demo app. Please also make sure that your building configuration(Such as Minimum API level, CPU arch,etc.) matches the pre-requisites of using Android SDK:[https://marketplace.zoom.us/docs/sdk/native-sdks/android/getting-started/prerequisites;](https://marketplace.zoom.us/docs/sdk/native-sdks/android/getting-started/prerequisites;) However, for the error code you got above, it is a network connection problem. If you are facing other issues other than the one you mentioned, please provide the error message or log here. 🙂 Thanks! ---
