Native Module Incall Manager tried to override IncallManagerModule

i am facing this error

Native Module Incall Manager tried to override IncallManagerModule . check to get Package Method in main Application.java it might be that module has been created twice. if this was your intention, set cannotOverrideExixistingmodule=True

my package.json file

include ':app'

i am calling InCallManager in App.js inside componentDidMount

  componentDidMount() {
    InCallManager.start({ media: 'audio' });
  }

every thing seems fine to me what is wrong

Start with MainApplication.java and inspect how PackageList is combined with the manual InCallManagerPackage registration. Then compare build.gradle and settings.gradle with the listed react-native-incall-manager dependency and reproduce the Android build or startup error. Done means the module is registered only as intended and the duplicate IncallManagerModule error no longer occurs.
