Notification Permission Pop-up Not Appearing on Android 13 with React Native Expo ============================================================================= Introduction ------------ With the release of Android 13, developers have reported issues with the notification permission pop-up not appearing in React Native apps built using Expo. This article aims to provide a detailed explanation of the issue, its causes, and potential solutions. Notification Permissions in Android ----------------------------------- Android has a permission system for notifications, which requires users to grant permission to an app before it can send notifications. This is done through a permission pop-up that appears when the app requests notification access. However, with the release of Android 13, some users have reported that the notification permission pop-up does not appear in React Native apps built using Expo. This can be a significant issue, as it prevents the app from sending notifications to the user. Causes of the Issue ------------------- The issue is caused by a change in the way Android 13 handles notification permissions for apps built using development tools like Expo. Specifically, Android 13 requires that the app be built in release mode and signed with a release key before the notification permission pop-up will appear. Additionally, the issue may be caused by a bug in Expo's notification module, which may not correctly request notification permissions on Android 13. Potential Solutions ------------------ To resolve the issue, there are several potential solutions: 1. Build the app in release mode and sign it with a release key. This will ensure that the notification permission pop-up appears on Android 13. 2. Use a different notification module that correctly requests notification permissions on Android 13. One such module is `react-native-permissions`, which can be used to request notification permissions in a cross-platform way. 3. Wait for a fix from Expo. Expo's developers are aware of the issue and are working on a fix. Once a fix is released, updating to the latest version of Expo should resolve the issue. Conclusion ---------- The issue of the notification permission pop-up not appearing on Android 13 with React Native apps built using Expo can be a significant one, but there are several potential solutions. By building the app in release mode, using a different notification module, or waiting for a fix from Expo, developers can ensure that their apps can send notifications to users on Android 13. Summary ------- * Android 13 requires that apps be built in release mode and signed with a release key before the notification permission pop-up will appear. * The issue may be caused by a bug in Expo's notification module. * Potential solutions include building the app in release mode, using a different notification module, or waiting for a fix from Expo.
