I'm experiencing the same behaviour when sharing using whatsapp. When sharing with email the file is attached but with no extension.

@matiasbontempo: what did you end up using? I keep finding your comments in multiple places with the same errors that I'm experiencing. 😄

Hey @lucasbento! Sadly, I have no updates. I might try to take a look at the code and try to solve it myself but I have no experience with iOS native code. If I have any kind of success I'll create a PR and let you know!

Thanks for posting this! It looks like you may not be using the latest version of React Native, v0.53.0, released on January 2018. Can you make sure this issue can still be reproduced in the latest version?

I am going to close this, but please feel free to open a new issue if you are able to confirm that this is still a problem in v0.53.0 or newer.

For anyone that's having a problem with this, I used file sharing with react-native-fetch-blob and react-native with PR react-native-share/react-native-share#215.

@sturmenta: your link is giving 404, if you still need help I think it's better to create an issue on react-native-share.

@lucasbento Sorry, delete the stackoverflow post because I did not have any kind of way to show the error I doubted they could help me, finally I had problems in the AndroidManifest.xml with the provider. This is the link to how I solved the problem published as an issue in react-native-share: react-native-share/react-native-share#227.

Thanks also for your help. Regards!
