How to Allow Your Android App to Open PDF Files on Android Q and Above

As an Android developer, you may find the need to enhance your application’s functionality by allowing users to open specific file types—like PDF—directly from a file manager. One common issue arises when your app does not show up as an option to open PDF files on devices running Android Q (also known as Android 10). In this guide, we'll discuss why this happens and how to address it effectively.

Understanding The Problem

When a user tries to open a PDF file from their file manager, they expect to be presented with a choice of applications, including your app, if it is capable of handling that file type. This behavior works well below Android Q, but developers have reported that their apps do not show on devices with Android Q and higher despite having the necessary permission configurations in their AndroidManifest.xml file. This creates a frustrating experience for users who want to view documents in their preferred app.

The Solution: Proper Intent Filters

To solve this problem, you need to set up the correct intent filters in your app’s manifest file. I will guide you through the intent filter configuration that allows your app to be recognized as a potential viewer for PDF files from the file manager on Android Q and above.

Step-by-Step Configuration

Define Your Activity: Be sure you have an activity that will handle the opening of PDF files. For instance, let's consider an OpenPdfActivity defined in your application.

Intent Filter Setup: Add the following intent filter configurations to your OpenPdfActivity. Here’s how it should look:

Breakdown of Intent Filters

Each component of the intent filter serves an important purpose:

Action: The VIEW action indicates that your app is capable of displaying data to the user.

Categories:

BROWSABLE allows the activity to be opened in response to a web link or other actions.

DEFAULT is essential for the app to be chosen as a handler for external intents.

Data:

The mimeType specifies that the app is concerned with PDF files.

The scheme attribute supports both file and content. This is critical because PDF files can originate from various sources and the system needs to recognize them accordingly.

Testing Your Implementation

After adding these intent filters, it’s crucial to test your app thoroughly:

Install your app on a device running Android Q or above.

Open a PDF file from a file manager and check that your app appears in the list of applications.

Select your app and verify that it opens the PDF correctly.

Conclusion

By correctly setting up your app’s intent filters, you can enhance user experience by allowing your application to open PDF files directly from the file manager, even on Android Q and above. Always remember to test rigorously across different Android versions to ensure compatibility and a seamless experience.

Expanding your app’s functionality not only improves user engagement but also opens up avenues for new users looking for reliable PDF viewing solutions. Follow these steps today and take one step closer to elevating your application's capabilities!
