Images add much-needed context and visual flair to Android applications. Picasso allows for hassle-free image loading in your application—often in one line of code!

Picasso.get().load("http://i.imgur.com/DvpvklR.png").into(imageView);

Many common pitfalls of image loading on Android are handled automatically by Picasso:

  • Handling ImageView recycling and download cancelation in an adapter.
  • Complex image transformations with minimal memory use.
  • Automatic memory and disk caching.

Features

Adapter Downloads

Adapter re-use is automatically detected and the previous download canceled.

Place Holders

Picasso supports both download and error placeholders as optional features.

Picasso.get()
    .load(url)
    .placeholder(R.drawable.user_placeholder)
    .error(R.drawable.user_placeholder_error)
    .into(imageView);

A request will be retried three times before the error placeholder is shown.

Resource Loading

Resources, assets, files, content providers are all supported as image sources.
