I’m following the information at: [https://www.npmjs.com/package/react-native-wowza-gocoder](https://www.npmjs.com/package/react-native-wowza-gocoder)

I could integrate the SDK finally, figuring out some integration issues.

But when I run it on Android (did not run it on iOS yet) it gives me a NullPointerException on BroadcastManager.getOrientationBehavior(). This is a screenshot of the exception.

I’m clueless on what is going wrong here. Appreciate any help.

I edited **/node\_modules/react-native-wowza-gocoder/android/src/main/java/com/rngocoder/BroadcastManager.java** and changed **getOrientationBehavior** method at the end of the file to return **WZMediaConfig.ALWAYS\_PORTRAIT** removing the “switch” block.

This fixed the crash above but then it only shows an all black screen. The reason for the black screen issue is that I have not given the app the Camera permission on the device. Giving the camera permission resolved all and it is now showing the camera preview.
