Android SDK


Cloudinary's Android SDK provides simple, yet comprehensive image and video upload, transformation, optimization, and delivery capabilities that you can implement using code that integrates seamlessly with your existing Android application.

This guide relates to the latest released version of the Cloudinary Android library.

For details on all new features and fixes from previous versions, see the CHANGELOG.

Quick example: Transformations

Take a look at the following transformation code and the image it delivers:

Copy to clipboard
MediaManager.get().url().transformation(new Transformation()
  .overlay(new Layer().publicId("cloudinary_icon")).gravity("south_east").x(5).y(5).width(50).opacity(60).effect("brightness:200").chain()
sample transformation

This relatively simple code performs all of the following on the original front_face.jpg image before delivering it:

  • Crop to a 150x150 thumbnail using face-detection gravity to automatically determine the location for the crop
  • Round the corners with a 20 pixel radius
  • Apply a sepia effect
  • Overlay the Cloudinary logo on the southeast corner of the image (with a slight offset). The logo is scaled down to a 50 pixel width, with increased brightness and partial transparency (opacity = 60%)
  • Rotate the resulting image (including the overlay) by 10 degrees
  • Convert and deliver the image in PNG format (the originally uploaded image was a JPG)

And here's the URL that would be included in the image tag that's automatically generated from the above code:

Quick example: File upload

The following Android code uses an unsigned upload preset to upload the dog.mp4 video to the specified account sub-folder using the public_id, my_dog. The video will overwrite the existing my_dog video if it exists. When the video upload is complete, the specified notification URL will receive details about the uploaded media asset.

Copy to clipboard
String requestId = MediaManager.get().upload("dog.mp4")
   .option("resource_type", "video")
   .option("folder", "my_folder/my_sub_folder/")
   .option("public_id", "my_dog")
   .option("overwrite", true)
   .option("notification_url", "")

Android SDK features

  • Build dynamic URLs for delivering images and videos with on-the-fly transformations
  • Implement direct file upload from your mobile application directly to your Cloudinary account
  • Support chunked upload for large files
  • Preprocess files before uploading
  • Handle asynchronous upload callbacks
  • Upload policy options (upload only on non-metered networks, only when charging, etc) globally or per upload request
  • Automatic error handling for network disconnections, timeouts, etc
  • Save bandwidth with a cache-enabled resource downloader


The Cloudinary Android SDK is available in modules. Select the modules to install based on the following table:

Module Features Depends on:
Transformations, Upload, Client side responsive Java core: 'com.cloudinary:cloudinary-core:[version]'
Image and video upload preprocessing Core
Seamless integrations with 3rd party download libraries. Core
Native upload widget with preview and preprocess UI Preprocess
All of the above All of the above (explicitly and implicitly).

The following instructions detail the installation of the Cloudinary Android library. Note that there is no need for any ProGuard configuration. Use one of the following options:

Gradle installation

Add the module(s) within the dependencies section of your build.gradle file. For example:

Copy to clipboard
// All:
compile group: 'com.cloudinary', name: 'cloudinary-android', version: '1.28.2'

// Download + Preprocess:
compile group: 'com.cloudinary', name: 'cloudinary-android-preprocess', version: '1.28.2'
compile group: 'com.cloudinary', name: 'cloudinary-android-download', version: '1.28.2'

Maven installation

Add the module(s) within the dependencies tag in your pom.xml file. For example

Copy to clipboard
// All:

// Download + Preprocess:

Manual installation

Download the following 2 files and put them in your libs folder:


To use the Cloudinary Android library you have to configure at least your cloud_name. You can additionally define a number of optional configuration parameters if relevant. You can find your account-specific configuration credentials in the dashboard of our Management Console.

The entry point of the library is the MediaManager object. The MediaManager.init() method must be called once per application lifecycle before using the Android library, preferably in Application.onCreate(). Setting the configuration parameters can be done either when initializing the library, or by using the CLOUDINARY_URL meta-data property in the AndroidManifest.xml file.

Config with init

To set the configuration parameters programmatically while initializing the MediaManager, pass a HashMap with parameters as the second argument of the init method. For example:

Copy to clipboard
Map config = new HashMap();
config.put("cloud_name", "myCloudName");
MediaManager.init(this, config);

Config with meta-data

Alternatively, you can add the CLOUDINARY_URL meta-data property to the AndroidManifest.xml file, within the application tag. For example:

Copy to clipboard

When using the meta-data property, no configuration is required when initializing the MediaManager:

Android capitalization and data type guidelines

When using the Android SDK, keep these guidelines in mind:

  • Parameter names: snake_case. For example: public_id
  • Classes: PascalCase. For example: MediaManager
  • Methods: camelCase. For example: upload
  • Pass parameter data as: Map

Sample project

The Android sample project uses Cloudinary's Android SDK to perform direct uploading with uploading progress indication, an image preview with advanced transformations, and video playback of adaptive streaming videos based on the ExoPlayer library.

You can also check out the Cloudinary Demo - eCommerce App on the Google play store, with the Android source code available on GitHub. The demo showcases some of Cloudinary's features, shows how to take advantage of existing open source libraries (e.g., Picasso, Glide, Fresco, Imageloader) and integrates them within a functional app. For more info, see Introducing the Cloudinary Demo Android App, Part 1.
