If your Expo app is getting stuck on the splash screen when a received notification is clicked (background mode), there could be several reasons for this behavior. Here are some common causes and potential solutions to resolve the issue:

  1. Missing Handling for Notification Click in Background: When a user clicks on a notification while the app is in the background, Expo sends the notification data to the app using an event listener. If your app doesn't handle this event correctly, it might get stuck on the splash screen.

    Solution: Ensure that you have set up the correct event listener to handle the notification when the app is in the background. In Expo, you can use the Notifications.addNotificationResponseReceivedListener function to listen for notification clicks in the background.

    javascript
    import { useEffect } from 'react'; import * as Notifications from 'expo-notifications'; const App = () => { useEffect(() => { const subscription = Notifications.addNotificationResponseReceivedListener((response) => { // Handle the notification data here console.log('Notification clicked:', response); }); return () => subscription.remove(); }, []); // The rest of your app code }; export default App;
  2. Permission Issues: If your app doesn't have the necessary permissions to receive notifications or run in the background, it might not be able to handle the notification click event correctly.

    Solution: Ensure that you have correctly configured the necessary permissions in your app's app.json or app.config.js file. Also, make sure that you have requested the required permissions from the user using the expo-permissions or expo-notifications libraries.

  3. Inconsistent Behavior on Android and iOS: On Android and iOS, the behavior of notification handling can be different. Ensure that you have tested the notification click behavior on both platforms and adapted your code accordingly.

  4. Async Operations Delay: If your app performs some time-consuming async operations during the notification click handling, it might lead to the app appearing stuck on the splash screen.

    Solution: Make sure that any async operations or network requests in your notification handling code are efficiently managed and don't block the app's UI thread. You can use async/await, Promises, or callbacks to handle async operations properly.

  5. App Initialization Issue: It's possible that some other parts of your app's initialization process are causing it to hang or freeze when handling notifications.

    Solution: Review your app's initialization code and check if any asynchronous tasks are blocking the app's execution. Make sure your app properly handles any loading or initialization states.

  6. Debugging and Error Handling: Implement proper error handling and debugging techniques to identify any issues that might be occurring when the notification is clicked.

If none of the above solutions resolve the issue, it's important to further investigate and debug the problem. You can use Expo's logging and debugging tools to get more insights into what might be causing the app to get stuck on the splash screen. Also, check for any error messages in the console or logcat that could provide additional information about the problem.
