Answer 2

As per my comment Try this :

final ImageView imageInToolbar = (ImageView) toolbar.findViewById(R.id.actionBarImage);
setSupportActionBar(toolbar);
imageInToolbar.setImageDrawable(ContextCompat.getDrawable(th‌​is, R.drawable.abc));

For loading image from server :

For Glide use :

Glide.with(this)
     .load(url) 
     .into(imageInToolbar);

In gradle : compile 'com.github.bumptech.glide:glide:3.8.0'

For picasso use :

Picasso.with(this).load(url).into(imageInToolbar);
