How to Effectively Use the File Picker in Android 11

Navigating the world of Android development can be challenging, especially when it comes to handling file operations. One common issue developers face is using the file picker in Android 11. In this guide, we will explore a problem encountered when using the file picker and provide an effective solution to ensure your application runs smoothly without crashes.

The Problem

In your Android application, you may want users to select files from their devices using a file picker. When attempting to implement this feature, many developers encounter issues, especially in Android 11. A typical scenario is where the application crashes, resulting in errors like:

This error occurs when the code attempts to access a file using the wrong path. Let's see how we can fix this.

Understanding the Cause of the Issue

When using ACTION_OPEN_DOCUMENT, the Android system provides a URI, which can be used to access the selected file. Here is the identified issue:

Misuse of the URI: Instead of directly utilizing the URI provided by the file picker, some developers try to convert it to a file path using methods like getRealPathFromURIWithProvider().

Scoped Storage: Android 11 has introduced scoped storage, which minimizes access to external storage to enhance privacy. As a result, frequently using direct file paths may lead to errors.

The Solution

To fix the problem and successfully implement a file picker in Android 11, follow these steps:

1. Properly Open the File Picker

Here’s a short snippet for correctly opening the file picker using Intent.ACTION_OPEN_DOCUMENT.

2. Handling the Result

Once the user selects a file, handle the result properly. Directly use the URI instead of trying to obtain the file path.

3. Uploading the File

When it comes time to upload the file, utilize the URI directly.

4. Error Handling

Make sure to handle errors gracefully. Avoid relying on legacy external storage methods or converting URIs to file paths, as they may not work on Android 11 and onwards.

Conclusion

By following these steps and utilizing the URI provided by the file picker directly, you can effectively implement a file picker in your Android 11 application without running into crashes or errors. Remember, as Android evolves, so do the methods of file handling. It’s essential to stay updated and adjust your practices accordingly.
