title: Android: Offine image caching with Picasso tags: android,android-picasso
If you want to cache images for offline access, it's fairly easy, but you have to include an old version of OkHTTP. Here's my gradle imports:
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'com.squareup.okhttp:okhttp:2.4.0'
After you've got those, then in the builder, you need to specify an argument for downloader and give it the OkHttpDownloader class, and give it a max cache size.
new Picasso.Builder(toolbar.getContext())
.downloader(new OkHttpDownloader(toolbar.getContext(), Integer.MAX_VALUE))
.build()
.load(s)
.into(target);
