A review of basic points of use The volley framework also does a lot of work on requesting network images, and provides several methods. This article describes the use of Imageloader to load network pictures.Imageloader's internal use of imagerequest to implement, its constructor can pass in a Imagecache cache parameters, implementation of the image caching function, but also can filter the duplicate links

This will address the image halo effect of image effects. The same as the front face is the pixel processing, the idea of this implementation can be found in the Android image processing series nine--image

This article describes the negative effects of image special effects processing. As before, pixels are processed, and algorithms are universal. Algorithm principle: the RGB values of the current pixel and the values after the difference of 255 are used as the RGB values of the current vertex. Example: ABC Evaluate the negative effect of point B: B. R = 255-B. R;

Resource class has this method, indicating that the resource is not referenced and can be put into the pool (no space is freed at this time). Bitmap also has this approach in Android, which means that the memory used to release bitmap. 1.
