Picasso gives out of memory when load an image

Question

I am using Picasso to load images from my server and display them in ImageView.

I observes some crash reports from user's phone where Out of Memory Exception happens when Picasso is trying to load an image into ImageView.

The stack trace as below:

java.lang.OutOfMemoryError

at android.widget.AbsListView.obtainView(AbsListView.java:2608)
at android.widget.GridView.makeAndAddView(GridView.java:1346)

The Code near MyAdapter.java:102 as below:

@Override
    public View getView(int position, View convertView, ViewGroup parent) {

    .....Some code .....

    Picasso.with(mContext)
    .load(url_to_server)
    .placeholder(R.drawable.default_placeholder)
    .into(holder.imageItem);  // Line 102

    .....Some code .....

    return convertView;
    }

Is there sth wrong with the way I use this library?

Answer 1

To load small images like icons o launchers we can use .setImageResource(image) However, to load big images is better to use Picasso and get the benefit of simplicity and local caching.

It is necesary to setup Picasso properly according to the documentation:

"Be sure to use fit() to resize the image before loading into the ImageView. Otherwise, you will consume extra memory, experience sluggish scrolling, or encounter out of memory issues if you render a lot of pictures".

if (imageUri != null && !imageUri.isEmpty()) {
   Picasso.with(context).load(imageUri)
  .fit().centerCrop()
  .placeholder(R.drawable.user_placeholder)
  .error(R.drawable.user_placeholder_error)
  .into(imageView);
}
