**Description** How to add a “Return to Meeting” button? I used this method in the `onCreate()` method, but it is giving a NullPointerException. ```auto public void inMeetingButton(){ initializeSdk(this); MeetingStatus status; status = ZoomSDK.getInstance().getMeetingService().getMeetingStatus(); if(status == MeetingStatus.MEETING_STATUS_INMEETING || status == MeetingStatus.MEETING_STATUS_IN_WAITING_ROOM || status == MeetingStatus.MEETING_STATUS_RECONNECTING || status == MeetingStatus.MEETING_STATUS_UNKNOWN || status == MeetingStatus.MEETING_STATUS_WAITINGFORHOST || status == MeetingStatus.MEETING_STATUS_CONNECTING){ button1.setVisibility(View.INVISIBLE); button3.setVisibility(View.VISIBLE); textview1.setVisibility(View.INVISIBLE); edittext1.setVisibility(View.INVISIBLE); til1.setVisibility(View.INVISIBLE); } else { button3.setVisibility(View.INVISIBLE); } ``` `button3` is the Return to Meeting button. **Which Android Client SDK version?** v5.5.1.1319 **Screenshots** ![Screenshot (17)](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/c/9/c9fbc95da1c157e259fd94740d77a7fb75cc0c7e.png) ![Screenshot (18)](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/3/1/318eefcd6fc429f3ecb09dd3dd3de3d4dee0e7e1.png) ![Screenshot (19)](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/a/0/a0b9b23c50342cd90527cb2811a330cab0c4b1a3.png) **Smartphone (please complete the following information):** - Device: Xiaomi Redmi Note 9 - OS: Android 10 ---

Hi @soumoghosh37, thanks for the post. The error you are seeing is happening because you are trying to access the `MeetingService` too soon. The SDK must be successfully initialized before any of the classes provided by it are non-null. You can find more information on how to initialize the SDK [here](https://marketplace.zoom.us/docs/sdk/native-sdks/android/mastering-zoom-sdk/sdk-initialization). Thanks! ---

Hi @jon.zoom, Actually I am initializing it **twice** (tried with once, did not work), first at the beginning of the `onCreate()` method, and then again in this method. My `iniatializeSdk()`: ```auto public void initializeSdk(Context context) { ZoomSDK sdk = ZoomSDK.getInstance(); ZoomSDKInitParams params = new ZoomSDKInitParams(); params.appSecret = Credentials.SDK_SECRET; params.appKey = Credentials.SDK_KEY; params.domain = Credentials.SDK_DOMAIN; params.enableLog = true; ZoomSDKInitializeListener listener = new ZoomSDKInitializeListener() { @Override public void onZoomSDKInitializeResult(int i, int i1) { } @Override public void onZoomAuthIdentityExpired() { } }; sdk.initialize(context, listener, params); } ``` My `onCreate()`: ```auto @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); initializeSdk(this); //Zoom SDK Initialization .... } ``` Also please check the question again, I have edited it and included the `initializeSdk()`. Thank you! ---

Hi @soumoghosh37, Thanks for providing the code snippets. Just calling the `initialize` method on the SDK does not mean that it has been successfully initialized. In your `ZoomSDKInitializeListener` instance, you will need to receive a result with an error code of `ZoomError.ZOOM_ERROR_SUCCESS`. Upon receiving this, you can begin using the SDK to join or start a meeting. Thanks! ---

Hi @jon.zoom Can you please tell me how to do this, or maybe give a link where I can find some information about this? I am not able to understand how to get a result from the instance. Thanks! ---

Hi @soumoghosh37, Our [SDK initialization documentation](https://marketplace.zoom.us/docs/sdk/native-sdks/android/mastering-zoom-sdk/sdk-initialization) should provide you with all of the information you need to properly initialize the SDK. If you have any specific questions on this flow, please let me know and I will be happy to help. 🙂 Thanks! ---
