如何在活动开始时用最少的时间显示大图像？

Question

In my wallpaper android app I have first activity in which user selects any one image and go to the next activity, and in second activity I show preview of image. It is loading and taking long time. How can I reduce the loading time? on the same network obviously. how can I preload this image? I used Glide as well as Picasso no difference in loading time.

Simple use cases with Glide's generated API will look something like this: ImageView imageView = (ImageView) findViewById(R.id.my_image_view); GlideApp.with(this).load("IMAGE URL").into(imageView); ImageView imageView = (ImageView) findViewById(R.id.my_image_view); GlideApp.with(this).load("IMAGE URL").into(imageView);
