Fresco is a powerful system for displaying images in Android applications.

In Android 4.x and lower, Fresco puts images in a special region of Android memory (called ashmem). This lets your application run faster - and suffer the dreaded OutOfMemoryError much less often.

Fresco also supports streaming of JPEGs.


How to set up dependencies in the app level build.gradle file:

dependencies {
    // Your app's other dependencies.
    compile 'com.facebook.fresco:fresco:0.14.1' // Or a newer version if available.

More information can be found here.

Getting Started with Fresco

First, add Fresco to your build.gradle as shown in the Remarks section:

If you need additional features, like animated GIF or WebP support, you have to add the corresponding Fresco artifacts as well.

Fresco needs to be initialized. You should only do this 1 time, so placing the initialization in your Application is a good idea. An example for this would be:

public class MyApplication extends Application {
    public void onCreate() {

If you want to load remote images from a server, your app needs the internt permission. Simply add it to your AndroidManifest.xml:

<uses-permission android:name="android.permission.INTERNET" />

Then, add a SimpleDraweeView to your XML layout. Fresco does not support wrap_content for image dimensions since you might have multiple images with different dimensions (placeholder image, error image, actual image, ...).

So you can either add a SimpleDraweeView with fixed dimensions (or match_parent):

    fresco:placeholderImage="@drawable/placeholder" />

Or supply an aspect ratio for your image:

    fresco:placeholderImage="@drawable/placeholder" />

Finally, you can set your image URI in Java:

SimpleDraweeView draweeView = (SimpleDraweeView) findViewById(;

That's it! You should see your placeholder drawable until the network image has been fetched.

Using OkHttp 3 with Fresco

First, in addition to the normal Fresco Gradle dependency, you have to add the OkHttp 3 dependency to your build.gradle:

compile "com.facebook.fresco:imagepipeline-okhttp3:1.2.0" // Or a newer version.

When you initialize Fresco (usually in your custom Application implementation), you can now specify your OkHttp client:

OkHttpClient okHttpClient = new OkHttpClient(); // Build on your own OkHttpClient.

Context context = ... // Your Application context.
ImagePipelineConfig config = OkHttpImagePipelineConfigFactory
        .newBuilder(context, okHttpClient)
Fresco.initialize(context, config);

JPEG Streaming with Fresco using DraweeController

This example assumes that you have already added Fresco to your app (see this example):

SimpleDraweeView img = new SimpleDraweeView(context);
ImageRequest request = ImageRequestBuilder
        .setProgressiveRenderingEnabled(true) // This is where the magic happens.

DraweeController controller = Fresco.newDraweeControllerBuilder()
        .setOldController(img.getController()) // Get the current controller from our SimpleDraweeView.

img.setController(controller); // Set the new controller to the SimpleDraweeView to enable progressive JPEGs.
