Glide

Glide is fast and efficient image loading library for Android that wraps image downloading, resizing, memory and disk caching, and bitmap recycling into one simple and easy to use interface. Glide includes a flexible api allowing it to plug in to almost any network stack. By default Glide uses a custom HttpUrlConnection based stack, but also includes utility libraries plug in to Google's Volley project or Square's OkHttp library instead.

Glide's primary focus is on making scrolling any kind of a list of images as smooth and fast as possible, but Glide is also effective for almost any case where you need to fetch, resize, and display a remote image.

Download

You can download a jar from GitHub's release page or to use the 3.0 alpha branch, use Gradle:

repositories {
  mavenCentral()
}

dependencies {
    compile 'com.github.bumptech.glide:glide:3.3.0'
    compile 'com.android.support:support-v4:19.0.0'
}

Or Maven:

In your module:

<dependency>
  <groupId>com.github.bumptech.glide</groupId>
  <artifactId>glide</artifactId>
  <version>3.3.0</version>
  <type>aar</type>
</dependency>
<dependency>
  <groupId>com.google.android</groupId>
  <artifactId>support-v4</artifactId>
  <version>r7</version>
</dependency>

How do I use Glide?

Checkout the GitHub wiki for pages on a variety of topics and links to javadocs.

Simple use cases will look something like this:

// For a simple view:
@Override
public void onCreate(Bundle savedInstanceState) {
    ...

    ImageView imageView = (ImageView) findViewById(R.id.my_image_view);

    Glide.with(this).load("http://goo.gl/h8qOq7").into(imageView);
}

// For a list:
@Override
public View getView(int position, View recycled, ViewGroup container) {
    final ImageView myImageView;
    if (recycled == null) {
        myImageView = (ImageView) inflater.inflate(R.layout.my_image_view,
                container, false);
    } else {
        myImageView = (ImageView) recycled;
    }

    String url = myUrls.get(position);

    Glide.with(myFragment)
        .load(url)
        .centerCrop()
        .placeholder(R.drawable.loading_spinner)
        .animate(R.anim.fade_in)
        .into(myImageView);

    return myImageView;
}

Volley

Volley is now an optional dependency that can be included via a utility library. To use Volley to fetch media over http/https:

With Gradle:

dependencies {
    compile 'com.github.bumptech.glide:volley-integration:3.3.0'
    compile 'com.mcxiaoke.volley:library:1.0.+'
}

Or with Maven:

<dependency>
    <groupId>com.github.bumptech.glide</groupId>
    <artifactId>volley-integration</artifactId>
    <version>3.3.0</version>
    <type>jar</type>
</dependency>
<dependency>
    <groupId>com.mcxiaoke.volley</groupId>
    <artifactId>library</artifactId>
    <version>1.0.5</version>
    <type>aar</type>
</dependency>

Then in your Activity or Application, register the Volley based model loader:

public void onCreate() {
  Glide.get(this).register(GlideUrl.class, InputStream.class, new VolleyUrlLoader.Factory(yourRequestQueue));
  ...
}

After the call to register any requests using http or https will go through Volley.

OkHttp

In addition to Volley, Glide also includes support for fetching media using OkHttp. To use OkHttp to fetch media over http/https:

With Gradle:

dependencies {
    compile 'com.github.bumptech.glide:okhttp-integration:3.3.0'
    compile 'com.squareup.okhttp:okhttp:2.0.+'
}

Or with Maven:

<dependency>
    <groupId>com.github.bumptech.glide</groupId>
    <artifactId>okhttp-integration</artifactId>
    <version>3.3.0</version>
    <type>jar</type>
</dependency>
<dependency>
    <groupId>com.squareup.okhttp</groupId>
    <artifactId>okhttp</artifactId>
    <version>2.0.0</version>
    <type>jar</type>
</dependency>

Then in your Activity or Application, register the OkHttp based model loader:

public void onCreate() {
  Glide.get(this).register(GlideUrl.class, InputStream.class, new OkHttpUrlLoader.Factory(yourOkHttpClient));
  ...
}

Status

Version 3.0 is in the beta stage with a nearly final api and is used in multiple open source projects at Google including in the Android Camera app and in the 2014 Google IO app. Comments/bugs/questions/pull requests welcome!

Build

Building Glide with gradle is fairly straight forward:

git clone [email protected]:bumptech/glide.git
cd glide
git checkout origin/3.0a
git submodule init && git submodule update
./gradlew jar

Note: Make sure your Android SDK has the Android Support Repository installed, and that your $ANDROID_HOME environment variable is pointing at the SDK.

Development

Follow the steps in the 'Build' section to setup the project and then edit the files however you wish. Intellij's IDEA 14 early access build cleanly imports both Glide's source and tests and is the recommended way to work with Glide. Earlier versions of intellij do not import the gradle project cleanly. Although Android Studio imports the source cleanly, it is not possible to run or debug the tests without manually modifying the tests' classpath. To open the project in Intellij 14 go to File > Open... > navigate to Glide's root directory > select settings.gradle.

Getting Help

Thanks

Thanks to the Android project and Jake Wharton for the disk cache implementation Glide's disk cache is based on, to Dave Smith for the gif decoder implementation Glide's gif decoder is based on and thanks also to everyone who has contributed code and reported issues!
