into(ImageView targetImageView) – It is provided by Picasso where you can Specify your target Imageview in which the image is supposed to get displayed in.īesides using the. But it will freeze the UI if you will call it from UI thread. get() – It returns a Bitmap object and loads an image synchronously. If you want to reduce the reduce image loading times and if you know that the image is needed by you shortly after then it could be used to fill the image cache in the background. It’s neither going to load the image into image view nor it is going to return any Bitmap. This method only saves the image into the disk or memory cache.
fetch() – It will asynchronously load the image into a background thread. Picasso loads the image in two ways synchronously and Asynchronously.

And if the image is not available in disk cache it will have to load it from the network.Ĭallbacks and Targets In Picasso In Android It is important to note that when you load an image, Picasso will always try memory cache first and if it can’t find the image in memory cache, it will try to find it in the disk cache. But if you are loading a lot of images Picasso will keep the most recent one in-memory cache and tries to keep all of them in the disk cache. If you are loading an image, Picasso load it in disk cache and memory cache. The Memory Cache is checked in UI thread. It is faster to write and access, but If you use memory cache then the application could be interrupted by another task like a phone call, and while in a background application might be killed and memory cache will be destroyed and application has to process each image again once the user resumes. Memory cache: It stores and loads the resource to and from memory. Here Background thread checks the disk cache. A disk cache can be used to help to decrease loading times when images are no longer available in-memory cache and can be used to persist processed Bitmaps. Now when the application resumes, it has to process each image again here the disk cache comes into rescue. Picasso utilizes two cachesĭisk Cache: If memory cache is used in the application then the application might be disrupted by phone call or anything else and being in the background the memory cache will be destroyed. Ĭaching is important to make sure that image loading is efficient and the user gets good experience.
In order to load Image with Picasso you to need an Internet permission in your Android Manifest file.
