**Description** Hi i try to build Android sample apps that zoom provide on github for Research n development purpose,already open it with android studio and do all the steps on [Android SDK Documentation](https://marketplace.zoom.us/docs/sdk/native-sdks/android/getting-started/install-sdk) page,like creating SDK Apps for generate SDK key & secret, and put sdk key & secret on AuthConstants.java,and try to put the jwt token too,but when i debug it on my device and run the sdk sample apps it appear error message “Failed to initialize zoom SDK Error: 1 internalErrorCode=0”, can anyone help me,is there something that i must to add to the project beside the sdk key & secrets on AuthConstants.java,fyi i already using zoom free trial account **Screenshots** ![photo_2020-01-30_13-29-49](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/3/3d40b0f2d333792eab1a05f1a0c72d08098addd4.jpeg) ---

Hi [rizkyrayd](https://devforum.zoom.us/u/rizkyrayd), Thanks for the post. The error code indicates that the JWT token is incorrect. What is the web domain you are using? To ensure your SDK key & secret are working, besides filling up the SDK key & secret in AuthConstants.java, please change the following in InitAuthSDKHelper.java ```auto ZoomSDKInitParams initParams = new ZoomSDKInitParams(); // initParams.jwtToken = SDK_JWTTOKEN; initParams.appKey = SDK_KEY; initParams.appSecret = SDK_SECRET; ``` If it works, then it means the key & secret are working, then you may refer to the instruction here: [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) to complete the JWT token. You can use either key & secret or JWT token for SDK initialization. Hope this helps. Thanks! ---

Hi [rizkyrayd](https://devforum.zoom.us/u/rizkyrayd), Could you elaborate a little bit more about the outsytem and the hybrid platform low code platform? Not. quite sure what kind of system you are referring to. Any wiki or link would be very helpful. Thanks! ---

Hi @kathuriasimran94, sorry to hear you’re running into an issue with generating your JWT. First, let’s make sure your key and secret values are correct. You can test this by setting them as your `appKey` and `appSecret` fields in `ZoomSDKInitParams`. Once you’ve verified that these values are correct and that the SDK is working, head over to [jwt.io](http://jwt.io) and create a JWT by copying the JSON format mentioned in the link you posted. Lastly, if you’re uncertain about any of the specific components of your JWT, feel free to ask and I will be more than happy to clarify. Thanks! ---

Hi @kathuriasimran94, thanks for the response. According to our [error codes](https://marketplace.zoom.us/docs/sdk/native-sdks/android/resource/error-codes), that means an illegal key/secret are being used. This most commonly occurs when using the wrong values for these fields. Please ensure that you are copying the key and secret for an SDK app on the marketplace. Thanks!
