Libraries like Picasso didn't fulfill our requirements because as stated "Picasso doesn't have a disk cache. It delegates to whatever HTTP client". An image download-and-cacher that also knows how to efficiently generate and retrieve thumbnails of various sizes. This library features:. Shutterbug is an Android library that lets you fetch remote images and cache them. It is particularly suited for displaying remote images in lists or grids as it includes a convenience subclass of ImageView FetchableImageView that make implementation a one-liner.
A dual memory and disk cache was implemented. It uses the same structure and interface. Sligh is an easy, sample and flexible library for loading, caching and displaying images on Android written in Kotlin. Images are cached to memory and to disk for super fast loading. UIL is a powerful and flexible library for loading, caching and displaying images on Android. UIL aims to provide a powerful, flexible and highly customizable instrument for image loading, caching and displaying.
It provides a lot of configuration options and good control over the image loading and caching process. An Android library for managing images and the memory they use. Fresco takes care of image loading and display, so you don't have to. It will load images from the network, local storage, or local resources, and display a placeholder until the image has arrived. It has two levels of cache; one in memory and another in internal storage.
In Android 4. User I wonder if you have a programmer App to run on your android? JANickerson I wonder if you have a programmer App to run on your android? Thanks for your swift reply. I have Qpython app and an HC module. That's what I used to communicate with the bootloader on the PIC chip. The only problem I have now is that I ain't really good in assembly programming, so I wish I have an Android app that will compile C program for me.
Please help me. Super Member. Why do you want to complicate your life with compiler apps? Hmm, thanks for that remark. So I've written python program that will communicate with HC Bluetooth module using the Qpython app. Those program are open-sourced, were built for x86 and ARM architectures I run it on Raspberry Pi ; so it should be possible to recompile them for Android, given there is GCC and appropriate libraries for Android.
That being said, it will not be trivial exercise. That's a good suggestion, but I don't have a PC to do the necessary conversion.
Why not use the Microchip Xpress online compiler? Superb Member. There's a missing post from dammy I guess he did not pay attention to Alan's signature line.
Microchip Xpress might help him. However, the IDE will work on many smartphone and tablet browsers. By the way, you must never perform network requests on the UI thread and since HoneyComb, Android doesn't let you do it. If you will use the core method of loading image from network then it would take larger amount of code. But if we will use a 3rd party library like picasso then we will achieve our goal in few lines of code.
And Picasso Library is the best and simplest I found so far. We only need to write the following to load an image from internet using picasso. But if we will not use picasso library or any other library we may need to do it using AsyncTask that will require more lines of code. Source: Picasso Android Tutorial. Picasso automatically handles all pitfalls associated with image downloading such as caching downloaded image, look up cache, cancelling existing request, performing image transormations and decoding, resizing and cropping of images.
And it allows you to customize it, you can configure memory for cache, add request transformer used for adding global information to every request, add bitmap config to handle decoding images for format not covered by default bitmap config.
It allows you to specify memory policy and network policy which makes it to use either cache or to download from the network. It allows you to add placeholder and error images to be used while downloading and in case of error in downloading respectively. Here is the code using latest version 2.

Improve this question. Code Maverick If you have to ask, don't use it. If you don't see what it can bring to your application, it means you don't need it so far. Add a comment. Active Oldest Votes. Just for the record for anyone new to Android or perhaps moving to Android from iOS Until something drastically changes, you absolutely have to use Picasso.
Not a joke. Honestly, it's that simple. The advantages are unbelievable. It's this easy to use: Picasso. Again, the only thing "better than" Picasso is if you move to Volley. BTW here's an excellent long article on Volley v.
