Understanding the React-Native-Audio-Toolkit Failed to Prepare Error

If you're diving into the world of mobile development with React Native, you might encounter various challenges. One particularly frustrating issue arises when trying to build your own Recorder/Player using React-Native-Audio-Toolkit. Users have reported facing a prepare failure specifically when using the iOS simulator. This post aims to explain the cause of this issue and provide a straightforward solution.

What's the Problem?

When you attempt to prepare your audio recorder with the following code snippet:

This error typically signifies that the recorder cannot prepare itself for audio recording. Notably, others have discovered that this challenge specifically occurs on iOS simulators, while the recorder works seamlessly on actual devices.

Analyzing the Solution: Update Your Info.plist

A significant factor that could lead to this error is the absence of required microphone permissions. The iOS simulator, unlike real devices, demands explicit permissions defined in the application’s info.plist file.

Steps to Fix the Error

To resolve the prepare failure, follow these steps:

Access Your Info.plist File:

Locate your React Native project directory and find the info.plist file, usually found under the iOS project folder.

Add Microphone Usage Description:

Open the info.plist file and insert the following lines:

Rebuild Your App:

Once you've updated the info.plist file, ensure to rebuild your app in the iOS simulator to apply the changes.

Testing the Fix

After implementing the above steps, rerun your app in the iOS simulator. If done correctly, the recorder should prepare without throwing the earlier error, and you can proceed with recording audio as intended.

Conclusion

Encountering the React-Native-Audio-Toolkit preparation failure can be worrisome, especially when developing on iOS simulators. However, by ensuring that your app has the proper permissions defined in the info.plist file, you can resolve this issue efficiently. With the right permissions in place, your recorder should work flawlessly both on simulators and real devices.

By following the above guide, you can confidently tackle related issues in your audio recording endeavors using React Native.
