How to Fix Android Glide Image Not Loading

In this tutorial, you'll learn about How to Fix Android Glide Image Not Loading. We cover key concepts, practical examples, and best practices to help you understand and apply this topic effectively.

The Problem

Glide shows a blank or placeholder image:

Glide.with(this).load(url).into(imageView) // shows nothing

Or the image loads on some devices but not others, or the log shows:

W/Glide: Load failed for https://example.com/image.jpg with size [0x0]

The image URL is unreachable, the ImageView size is zero, or Glide is used with a destroyed context.

Quick Fix

Step 1: Verify the image URL

Glide.with(this)
    .load(url)
    .placeholder(R.drawable.placeholder)
    .error(R.drawable.error)
    .into(imageView)

Add a fallback to distinguish between loading (placeholder) and failure (error). If the error drawable appears, the URL or network is the issue.

Step 2: Test the URL in a browser

curl -I https://example.com/image.jpg

Expected:

HTTP/2 200
Content-Type: image/jpeg
Content-Length: 234567

If the server returns 403 or the content type is wrong, Glide cannot decode it. Some servers block automated downloads.

Step 3: Override the target size

Glide.with(this)
    .load(url)
    .override(800, 600)
    .into(imageView)

Glide uses the ImageView dimensions to determine the resolution to download. If the view has zero width or height (e.g., inside a ConstraintLayout with no constraints), Glide downloads the full resolution or fails.

Step 4: Use the application context

// Use application context for long-lived loads
Glide.with(applicationContext).load(url).into(imageView)

If the Activity or Fragment context is destroyed, Glide cancels the request. For tasks that outlive the UI, use the application context.

Step 5: Clear the Glide cache

Glide.get(this).clearDiskCache()
Glide.get(this).clearMemory()

A corrupted cache can prevent loading. This clears both disk and memory caches.

Step 6: Check for HTTPS/TLS issues

// Custom OkHttp client for Glide
val client = OkHttpClient.Builder()
    .connectTimeout(30, TimeUnit.SECONDS)
    .build()

Glide.init(this, GlideBuilder().setDefaultRequestOptions(
    RequestOptions().diskCacheStrategy(DiskCacheStrategy.ALL)
))

If the server uses an outdated SSL configuration, Glide fails silently.

Step 7: Use a specific decode format

Glide.with(this)
    .asBitmap()  // Force bitmap decoding
    .load(url)
    .into(imageView)

Some URLs return GIF or WebP images that need a specific decoder. asBitmap forces the standard bitmap pipeline.

Prevention

• Always set placeholder and error drawables in Glide requests.
• Ensure ImageViews have explicit width/height or match constraints.
• Use override for fixed-size images to save memory.

Common Mistakes with glide image load

1. Forgetting that lazy evaluation defers computation until the value is forced, causing space leaks with unevaluated thunks
2. Using return to exit a function early instead of wrapping a pure value in the monad
3. Mixing let bindings with <- bindings in do notation, producing type errors

These mistakes appear frequently in real-world Android code. DodaTech's contributors have identified these patterns through analysis of open-source projects and production systems.

Practice Exercise

Write a pure function that safely divides two integers using Maybe, then test it with edge cases like division by zero and negative numbers.

This exercise reinforces the concepts covered in this guide. Try implementing it before checking online solutions.
