Answer 1

You can either place an ImageView in your XML layout or create one dynamically and add it to the activity. Then simply set the image for the ImageView to display.

Try this code

AsyncHttpClient fileDownload = new AsyncHttpClient();
String[] allowedContentTypes = new String[] { "image/png", "image/jpeg" };
fileDownload.get("http://server.com/file.png", new BinaryHttpResponseHandler(allowedContentTypes) {
       @Override
       public void onSuccess(byte[] fileData) {
        //Do Something here to view files in activity  
         Bitmap bmp=BitmapFactory.decodeByteArray(fileData,0,fileData.length); 
         ImageView img = (ImageView) findViewById (R.id.imageview1);
         img.setImageBitmap(bmp);
         }
