Android - Universal Image Loader
Start
  Basic usage
  • Load an image, decode it into a bitmap, and display the bitmap in an `ImageView` (or any other view which implements the `ImageAware` interface): 
    ImageLoader.getInstance().displayImage(imageUri, imageView);
  • Load an image, decode it into a bitmap, and return the bitmap to a callback: 
    ImageLoader.getInstance().loadImage(imageUri, new SimpleImageLoadingListener() {
    @Override
    public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
        // Do whatever you want with the bitmap.
    }
});
  • Load an image, decode it into a bitmap and return the bitmap synchronously: 
    Bitmap bmp = ImageLoader.getInstance().loadImageSync(imageUri);
    •   Initialize Universal Image Loader
  • Add the following dependency to the **build.gradle** file: 
    compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'
  • Add the following permissions to the **AndroidManifest.xml** file: 
    <uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
  • Initialize the Universal Image Loader. This must be done before the first usage: 
    ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(this)
    // ...
    .build();
ImageLoader.getInstance().init(config);

    The full configuration options can be found here (opens new window).
