Troubleshooting Image Loading Issues in Android with Glide

Are you encountering issues while trying to load an image from a file path into an ImageView using the Glide library in Android? You're not alone! This is a common problem faced by many Android developers, especially when handling images from the device's gallery. In this guide, we'll walk through the issue, understand why you're facing it, and explore a straightforward solution.

The Problem: Unable to Load Image from File Path

Imagine this scenario: you have an application that allows users to select images from their galleries, and you are storing the file path in a database for later use. However, when you try to load the image into an ImageView, it fails to display. Here’s a snippet of code to illustrate the problem:

In this code segment, once you retrieve the image path and store it in imgS, you may attempt to display it like this:

While the file exists at the specified path, the image simply does not show up in the ImageView. What could be the issue?

Understanding the Root Cause

The most likely issue here relates to the storage access permissions, especially given the changes in Android storage policies over recent years. The access to files on external storage has become more restrictive for newer versions of the Android operating system. To ensure your application can read the external storage, you may need to make a small but crucial change in the AndroidManifest.xml file.

The Solution: Enable Legacy Storage Access

To solve this issue, follow these steps:

Open AndroidManifest.xml: This file is found in the app/src/main directory of your Android project.

Add the Legacy Storage Flag: Inside the Application tag, add the attribute android:requestLegacyExternalStorage="true".

Here’s how your Application tag should look:

By adding this attribute, you instruct the system to grant legacy access to the external storage, allowing your app to interact with it as it did before the change in storage policies. This should resolve the issue of loading images using Glide from file paths.

Summary of Steps to Fix Image Loading with Glide

Open your AndroidManifest.xml file.

Locate the Application tag.

Insert android:requestLegacyExternalStorage="true" within the tag.

Save your changes and rebuild your project.

Final Thoughts

Now that we've addressed how to fix the Glide image loading issue from file paths, you can smoothly display images stored in the device's external storage. Always remember the importance of managing storage permissions and storage access policies as Android continues to evolve.

By following the detailed steps outlined above, you should be able to effectively work with images in your Android application. Happy coding!
