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!


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.


Adapter Downloads

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