Unable to call React native function from Android

Question

I am trying to call a function from native to react native . But I am getting this runtime exception

Tried to access a JS module before the React instance was fully set up. Calls to "
          + "ReactContext#getJSModule should only happen once initialize() has been called on your "
          + "native module.";

I am following Facebook react native documentation. And did went through many questions regarding this topic but nothing helps my issue.I am getting CatalystInstance null in getJsmodule.

Answer 1

After debugging I got to know that I was missing current react context in MyActivity which is required to call getJSModule . So I extends my MainActivity from Activity to ReactActivity.
