What is Expo Document Picker?

Before we dive into the solution, let’s quickly recap what Expo Document Picker is. Expo Document Picker is a library provided by Expo that allows users to select documents from their device’s file system. It’s a crucial feature for many apps that require users to upload or select files.

The Problem: Expo Document Picker Not Allowing Document Selection

Now, back to the problem at hand. You’ve implemented the Expo Document Picker, but for some reason, it’s not allowing you to select a document. You might see an error message, or the picker might simply close without doing anything. Frustrating, right?

Reasons Behind the Issue

Before we delve into the solutions, let’s understand the possible reasons behind this issue:

• Permissions not granted
• Incorrect implementation of Document Picker
• Device-specific issues
• Conflicting libraries or plugins

Troubleshooting Steps

Now that we’ve identified the possible reasons, let’s go through the troubleshooting steps to resolve the issue:

Step 1: Check Permissions

The first and most crucial step is to ensure that your app has the necessary permissions to access the device’s file system. Add the following permissions to your `app.json` file:

"android": {
  "permissions": ["READ_EXTERNAL_STORAGE", "WRITE_EXTERNAL_STORAGE"]
}

For iOS, you’ll need to add the following to your `Info.plist` file:

<key>NSDocumentPickerAllowedUTIs</key>
<array>
    <string>kUTTypePDF</string>
    <string>kUTTypeText</string>
</array>

Step 2: Verify Implementation

Double-check your implementation of the Expo Document Picker. Make sure you’ve followed the official documentation and implemented it correctly.


import * as DocumentPicker from 'expo-document-picker';

const handleSelectDocument = async () => {
const result = await DocumentPicker.getDocumentAsync({
type: '*/*',
copyToCacheDirectory: true,
});

if (result.type === 'success') {
console.log(result.name, result.uri);
} else {
console.log('cancelled');
}
};

Step 3: Check for Conflicting Libraries or Plugins

Sometimes, conflicting libraries or plugins can cause issues with the Document Picker. Try removing any recently installed libraries or plugins and see if the issue persists.

Step 4: Test on Different Devices

If the issue is device-specific, try testing your app on different devices or emulators. This will help you identify if the problem is specific to a particular device or platform.

Additional Tips and Tricks

Here are some additional tips and tricks to help you troubleshoot and resolve the issue:

• Make sure your app has the correct package name and identifier.
• Check the device’s storage permissions and settings.
• Try using a different file type or mime type in the Document Picker.
• Clear the app’s cache and data.
