Reduce memory usage of Android applications

Question

I am developing a simple Android application which displays a list of users by obtaining their details along with a profile picture from a server. The application consumes a huge amount of RAM(about 180MB). When I analyzed the memory consumption, most of the memory was consumed to display the bitmaps using Picasso. I use a recycler view to display the list of users. Below is the code fragment I use to set the profile images.

public static void setImageURL(Context ctx, String url, ImageView imageView) {
    Picasso.with(ctx).invalidate(url);
    Picasso.with(ctx).load(url).networkPolicy(NetworkPolicy.NO_CACHE).memoryPolicy(MemoryPolicy.NO_CACHE).into(imageView);
}

Please give me some suggestions to minimize this memory consumption. Thanks in advance.

Answer 1

The problem was with loading images using Picasso without fitting them. Simply adding fit() after load() resolved the issue.

   Picasso.with(ctx).load(url).fit().networkPolicy(NetworkPolicy.NO_CACHE).memoryPolicy(MemoryPolicy.NO_CACHE).into(imageView);
