Handling shared link on Android about react-native-share-menu HOT 9 CLOSED

Ok great. Thanks for the confirmation. I was going to try that but worried that after a successful share the state of sharedContent would no longer be null, so I would then have to also check if it changes...

1. I don't think it's needed... you could write that code directly in the Java module if you want: https://github.com/meedan/react-native-share-menu/blob/master/android/src/main/java/com/meedan/ShareMenuModule.java#L43. But then you would need to fork the module and it would work only for your specific case.

2. I think you should be able to call this in any component: https://github.com/meedan/react-native-share-menu/blob/master/example/index.android.js#L25

Great. Thanks for the advice.
Do you know if it's possible to bounce into the app at a particular screen in the Navigation Stack rather than at the root of the Navigation Stack?

You should be able to do that with react-navigation, and navigate to a particular screen in the navigation stack when new shared text is received.

Forgive the silly question, but I can't figure out how to use your getSharedText function to detect when there is NO shared text. The callback only fires when the function successfully finds text (or image), but if not, it returns out of the function without returning anything. Is there something I am missing about your logic? Thanks again for the help.

I'm not sure I understand the question... how are you able to "share nothing"?

from react-native-share-menu.

Thanks a lot for the quick reply.

Apologies my question was unclear. Here's my use case:
Every time the home screen loads, I want to check for shared text in case the user is coming into the app via the Android share url button in chrome (for example). My problem is that when there is no share activity detected, ShareMenu.getSharedText immediately escapes and doesn't execute the if/else condition. Here is the code I am using in componentDidMount() ...

ShareMenu.getSharedText((text :string) => { if (text && text.length) { let comment = "empty comment" var share = { link: text, comment: comment } that.props.navigation.navigate ('AndroidShareScreen', { share: share }) } else { //if no share detected, go to login screen that.props.navigation.navigate ('LoginScreen') } }) */

I noticed this line in your ShareMenuModul.java file which means the behaviour I noticed is by design:
if(mActivity == null) { return; }

So, I'm wondering if it's possible to use your ShareMenu module to detect when there is NO share when the home screen loads (i.e. no intent, or activity)? Since getSharedText doesn't execute anything, or return anything when there is no intent detected, I can't figure out how to detect the case where there is NO shared text.

Thanks again!

I suggest that you have the shared information in a state and populate the content there when there is shared content. When there isn't, the state will remain null and then you can go to the login screen when the state is null. Something like that below:

class Test extends Component {
  constructor(props) {
    super(props); 
    this.state = {
      sharedContent: null,
    }
  }

  componentWillMount() {
    ShareMenu.getSharedText((text :string) => {
      if (text && text.length) {
        this.setState({ sharedContent: text });
      }
    })
  }

  componentDidMount() {
    if (!this.state.sharedContent) {
      // no share detected
    }
  }
}
