In our app the main application is responsible for other features too, not just ReactActivity specific things. Because of the above reason I don't want to make my MainApplication extend ReactApplication, and I don't want my MainActivity to extend ReactActivity either. I was able to get the latter to work, but whenever I remove the extension of ReactApplication from MainApplication, my app crashes on launching RN bundle with the error:

java.lang.ClassCastException: com.package.MainApplication cannot be cast to com.facebook.react.ReactApplication

What can I do in this scenario? Is there any way that I perform all the operations that happen in MainApplication inside of MainActivity. This is what the related components of my MainActivity look like for reference:

class MainActivity : AppCompatActivity(), DefaultHardwareBackBtnHandler, Screen,
    {
    private val mDelegate = this.createReactActivityDelegate()
    fun getMainComponentName(): String {
        return "MainBundle"
    }

    private fun createReactActivityDelegate(): ReactActivityDelegate {
        return object : ReactActivityDelegate(this, this.getMainComponentName()) {
            override fun getReactNativeHost(): ReactNativeHost {
                return createReactNativeHost(application)
            }
        }
    }

    private fun createReactNativeHost(app: Application?): ReactNativeHost {
        return object : ReactNativeHost(app) {
            override fun getUseDeveloperSupport(): Boolean {
                return false
            }

            override fun getPackages(): List<ReactPackage> {
                return Arrays.asList<ReactPackage>(
                    MainReactPackage()
                )
            }

            override fun getBundleAssetName(): String? {
                return "my.react.bundle"
            }
        }
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        mDelegate.onCreate(savedInstanceState)
    }
