To create an Async class as an inner class in our MainActivity class. The use of Asyn class is very important since it prevents us from downloading our remote image using the main application thread.

Code :


import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.AsyncTask;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.ImageView;

import java.io.InputStream;

public class ImageloadActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_imageload);

        ImageView imgPhoto = (ImageView)findViewById(R.id.ivPhoto);

        String urlPath = "http://10.42.0.1/dsms/backend/web/stud_photos/119426.jpg";

        Downloadimagefromurl downloadTask = new Downloadimagefromurl(imgPhoto);
        downloadTask.execute(urlPath);

    }



    private class Downloadimagefromurl extends AsyncTask<String,Void,Bitmap>{

        ImageView bmImg;

        public Downloadimagefromurl(ImageView bmImg) {
            this.bmImg = bmImg;
        }

        @Override
        protected Bitmap doInBackground(String... urls) {
            String pathFile = urls[0];
            Bitmap bitmap = null;

            try {
                InputStream inp = new java.net.URL(pathFile).openStream();
                bitmap = BitmapFactory.decodeStream(inp);
            } catch (Exception e){
                Log.e("Error",e.getMessage());
                e.printStackTrace();
            }

            return bitmap;
        }

        @Override
        protected void onPostExecute(Bitmap bitmap) {
            bmImg.setImageBitmap(bitmap);
        }

    }




}
