Glide

Maven Central Build Status Report an issue with Glide

Glide is a fast and efficient open source media management and image loading framework for Android that wraps media decoding, memory and disk caching, and resource pooling into a simple and easy to use interface.

Glide supports fetching, decoding, and displaying video stills, images, and animated GIFs. Glide includes a flexible API that allows developers 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 releases page.

Or use Gradle:

repositories {
  mavenCentral() // jcenter() works as well because it pulls from Maven Central
}

dependencies {
  compile 'com.github.bumptech.glide:glide:4.0.0-RC0'
  compile 'com.android.support:support-v4:25.3.1'
  annotationProcessor 'com.github.bumptech.glide:compiler:4.0.0-RC0'
}

Or Maven:

<dependency>
  <groupId>com.github.bumptech.glide</groupId>
  <artifactId>glide</artifactId>
  <version>4.0.0-RC0</version>
</dependency>
<dependency>
  <groupId>com.google.android</groupId>
  <artifactId>support-v4</artifactId>
  <version>r7</version>
</dependency>
<dependency>
  <groupdId>com.github.bumptech.glide</groupId>
  <artifactId>compiler</artifactId>
  <version>4.0.0-RC0</version>
  <optional>true</optional>
</dependency>

For info on using the bleeding edge, see the Snapshots wiki page.

ProGuard

Depending on your ProGuard (DexGuard) config and usage, you may need to include the following lines in your proguard.cfg (see Configuration wiki for more details):

-keep public class * implements com.bumptech.glide.module.GlideModule
-keep public enum com.bumptech.glide.load.resource.bitmap.ImageHeaderParser$** {
  **[] $VALUES;
  public *;
}

# for DexGuard only
-keepresourcexmlelements manifest/application/meta-data@value=GlideModule

How do I use Glide?

Checkout the documentation for pages on a variety of topics, and see the javadocs.

For Glide v3, see the wiki.

Simple use cases with Glide's generated API will look something like this:

// For a simple view:
@Override public void onCreate(Bundle savedInstanceState) {
  ...
  ImageView imageView = (ImageView) findViewById(R.id.my_image_view);

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

// For a simple image 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);

  GlideApp
    .with(myFragment)
    .load(url)
    .centerCrop()
    .placeholder(R.drawable.loading_spinner)
    .into(myImageView);

  return myImageView;
}

Status

Version 3 on the 3.0 branch is a stable public release used in multiple open source projects at Google including in the Android Camera app and in the 2014 Google IO app. Version 4 is currently under development on the master branch.

Comments/bugs/questions/pull requests are always welcome! Please read CONTRIBUTING.md on how to report issues.

Compatibility

  • Android SDK: Glide requires a minimum API level of 10.
  • OkHttp 2.x: there are optional dependencies available called okhttp-integration, see Integration Libraries wiki page.
  • OkHttp 3.x: there are optional dependencies available called okhttp3-integration, see Integration Libraries wiki page.
  • Volley: there are optional dependencies available called volley-integration, see Integration Libraries wiki page.
  • Round Pictures: CircleImageView/CircularImageView/RoundedImageView are known to have issues with TransitionDrawable (.crossFade() with .thumbnail() or .placeholder()) and animated GIFs, use a BitmapTransformation (.circleCrop() will be available in v4) or .dontAnimate() to fix the issue.
  • Huge Images (maps, comic strips): Glide can load huge images by downsampling them, but does not support zooming and panning ImageViews as they require special resource optimizations (such as tiling) to work without OutOfMemoryErrors.

Build

Building Glide with gradle is fairly straight forward:

git clone git@github.com:bumptech/glide.git # use https://github.com/bumptech/glide.git if "Permission Denied"
cd glide
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 or add a local.properties file in the root project with a sdk.dir=... line.

Samples

Follow the steps in the Build section to setup the project and then:

./gradlew :samples:flickr:run
./gradlew :samples:giphy:run
./gradlew :samples:svg:run

You may also find precompiled APKs on the releases page.

Development

Follow the steps in the Build section to setup the project and then edit the files however you wish. Intellij IDEA 14 cleanly imports both Glide's source and tests and is the recommended way to work with Glide.

To open the project in IntelliJ IDEA:

  1. Go to File menu or the Welcome Screen
  2. Click on Open...
  3. Navigate to Glide's root directory.
  4. Select build.gradle

Getting Help

To report a specific problem or feature request, open a new issue on Github. For questions, suggestions, or anything else, email Glide's discussion group, or join our IRC channel: irc.freenode.net#glide-library.
