How can i get image from image url in image view.
My imageUrl is coming from databaseadapter. In Fields class LocationImage dataype is string but in setBackgroundResource method it is asking for int value as parameter. LocationImage url is getting from database, so that i've taken that as string variable.code lines are here.

Bitmap mbmp = BitmapFactory.decodeStream(new java.net.URL("urlname").openStream());
Imageview_ref.setImageBitmap(mbmp);
