Possible unhandled promise rejection

[davoam]

Thanks for the great library!

Every time I open the app in the Android emulator, I see this warning: "Possible unhandled promise rejection..." (see more details in the screenshot). I understand that this library is not expected to work on the Android emulator without installed Google Play services.

The issue isn't that the library isn't working, but rather the warning itself. It's not possible to catch and conditionally ignore it.

The error is thrown in withIAPContext.ts file. There is no way to pass on error handlers to this HOC.

purchaseUpdatedListener expects the second argument to be a function, if a function is not given it throws an error which causes the mentioned warning.

Of course, we can conditionally wrap with this HOC, for example detect Android emulator and don't wrap at all, but in this case the library won't work on emulators with installed GooglePlay services.

Another possible solution is to allow passing on error handler to withIAPContext HOC.

Are there any other ways to ignore this error?

withIAPContext HOC has been removed in react-native-iap v14+.

You are using an older version (v12 or v13). Please upgrade to v14+ which uses the new useIAP hook instead.

Migration

In v14+, use the useIAP hook directly with error handling:

import { useIAP } from 'react-native-iap';

const MyComponent = () => {
  const { connected, products } = useIAP({
    onPurchaseError: (error) => {
      // Handle errors here - no unhandled promise rejections
      console.log('Purchase error:', error);
    },
  });

  // Your component logic
};

Benefits of v14+

• No more withIAPContext HOC
• Built-in error handling via onPurchaseError callback
• Cleaner API with useIAP hook
• Better emulator handling

Migration Guide

Please follow the migration guide to upgrade:

Note

Versions below v14 are no longer supported. Use at your own risk.
