Requesting permissions makes the app crash on a physical device. (dev client)

[thebiltheory]

Perhaps I'm doing something wrong but I made sure to follow the doc.

The app crashes on a physical device every time I run requestPermissionsAsync.

Here is a simple implementation of a screen. I stripped everything from the screen to isolate the issue.

Permissions are also well configured in app.json.

Am I missing something?

For what it's worth. It is also crashing when using requestPermissionsAsync from Audio.

import { Audio } from "expo-av";
...

  useEffect(() => {
    async function requestPermissions() {
      console.log("⁉️ Requesting permissions");

      const result = await Audio.requestPermissionsAsync();

      console.log("Request permissions result", result);

      if (!result.granted) {
        console.warn("Permissions not granted", result);
        return;
      }
    }

    requestPermissions();
  }, []);

Hey @thebiltheory!, here's a few things you might want to check:

• Whether you've ran another development build of your app after installing this package (npx expo run:android or npx expo run:ios). As this package contains native Swift & Kotlin code, you'll need to run this once so that the app is bundled with the native code.
• Whether your project has Expo as a dependency. This project uses Expo APIs from their permissions system to request permissions.

If those don't work, could you provide me the following:

• Wrapping the requestPermissionsAsync() in a try/catch, and then console.log the error, and paste it here
• Whether you're running on Android/iOS and what version

[thebiltheory]

Hey @jamsch, Thanks for the fast response!!

• ✅ I always run expo run:ios
• ✅ Got expo as a dependency.

Wrapping it in a try/catch doesn't work. The app closes immediately. It's really hard to tell what causes the issue.

I'm running ios 18 tho.

EDIT: Ran an iPhone 16 simulator with ios18

[TCC] This app has crashed because it attempted to access
privacy-sensitive data without a usage description.  The app's
Info.plist must contain an NSMicrophoneUsageDescription key with
a string value explaining to the user how the app uses this
data.

@thebiltheory That looks like the app wasn't built with the config plugin. Have you added that in to your app.json? You can copy the contents from the installation step 2 on the readme. It's also likely why expo-av wasn't working for you either. You also may need to run a fresh prebuild (npx expo prebuild --clean) to regenerate the android/iOS folders with the config from app.json.

[thebiltheory]

@jamsch I did! I have also prebuild the app many times

It was working with ios17 tho.

[jamsch]

@thebiltheory Very strange. Just to confirm when you run the prebuild, does your app include the permissions in ios/[app_name]/Info.plist? (also small nit: you've got expo-asset there twice)

[thebiltheory]

I feel stup*d.😂 Removing expo-asset did the trick!

Thanks for being my rubber duck @jamsch.

Take aways:

1. Granularly double check configuration.
2. Be more cautious during the rebase of a branch.

Also. Thank you for this library.

[thebiltheory]

Fixed.
