Glide
=====

[![Build Status](https://travis-ci.org/bumptech/glide.svg?branch=master)](https://travis-ci.org/bumptech/glide)

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

![](static/glide_logo.png)

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][1].

Or use Gradle:

```groovy
repositories {
  mavenCentral()
}

dependencies {
    compile 'com.github.bumptech.glide:glide:3.5.1'
    compile 'com.android.support:support-v4:19.1.0'
}
```

Or Maven:

```xml
<dependency>
  <groupId>com.github.bumptech.glide</groupId>
  <artifactId>glide</artifactId>
  <version>3.5.1</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][2] for pages on a variety of topics, and see the [javadocs][3].

Simple use cases will look something like this:

```Java

// 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)
        .crossFade()
        .into(myImageView);

    return myImageView;
}

```

OkHttp and Volley
-----------------
Support for OkHttp and Volley is provided by integration libraries you can optionally include as dependencies. The
integration libraries are available via Maven or the [releases page][1].

For instructions on including either the OkHttp or the Volley integration libraries, see the
[Integration Libraries][12] wiki page.

Android SDK Version
-------------------
Glide requires a minimum sdk version of 10.

License
-------
BSD, part MIT and Apache 2.0. See LICENSE file for details.

Status
------
Version 3 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. Comments/bugs/questions/pull requests welcome!

Build
------
Building Glide with gradle is fairly straight forward:

```
git clone git@github.com:bumptech/glide.git
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
```

Development
-----------
Follow the steps in the 'Build' section to setup the project and then edit the files however you wish.
[Intellij IDEA 14][4] cleanly imports both Glide's source and tests and is the recommended way to work with Glide.

To open the project in Intellij 14:

1. Go to File.
2. Click on 'Open...'
3. Navigate to Glide's root directory.
4. Select glide-parent.iml

Getting Help
------------
To report a specific problem or feature request, [open a new issue on Github][5]. For questions, suggestions, or
anything else, join or email [Glide's discussion group][6].

------------
