Lets start loading a image using this Fresco Image Library.

activity_main

Starting with layout design add a image view also called as DraweeView as

<com.facebook.drawee.view.SimpleDraweeView
    android:id="@+id/compLogo"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:padding="20dp">

    <com.facebook.drawee.view.SimpleDraweeView
        android:id="@+id/compLogo"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</LinearLayout>

MainActivity

Then start initializing Fresco Image Library in the activity where we want to load the image

Fresco.initialize(this);

make sure you initialize the library just before

setContentView(R.layout.activity_main);

because we are using the DraweeView in layout file which is to be initialized before.

Initialize SimpleDraweeView

SimpleDraweeView draweeView = (SimpleDraweeView) findViewById(R.id.compLogo);

add your image url

Uri imageUri = Uri.parse("Image Url Here");

then set the image to view as

draweeView.setImageURI(imageUri);

import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;

import com.facebook.drawee.backends.pipeline.Fresco;
import com.facebook.drawee.view.SimpleDraweeView;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Fresco.initialize(this); // Initialize

        setContentView(R.layout.activity_main);

        Uri imageUri = Uri.parse("Image Url Here");
        SimpleDraweeView draweeView = (SimpleDraweeView) findViewById(R.id.compLogo);
        draweeView.setImageURI(imageUri);

    }
}
