android - Customizing the setError icon for EditText

I want to set a setError method to my EditText, with a custom icon instead of the default Android icon. So I tried this:

((EditText)findViewById(R.id.edtTitle)).setError(getResources().getText(R.string.errEmptyTitle), 
         getResources().getDrawable(R.drawable.ico_warning_small);

It shows me the custom message, but not the custom icon. I tried this as well:

Drawable warning = (Drawable)getResources().getDrawable(R.drawable.ico_warning_small);
((EditText)findViewById(R.id.edtTitle))
      .setError(getResources().getText(R.string.errEmptyTitle), warning);

Pretty much the same, but I still decided to give it a go. However this also didn't help - I still can't see the icon. I tried to use some other Android system icon, just to see if I see them and no, I don't see them as well.

So what am I doing wrong? Is there any way to set that custom icon?

You need to set the bounds on the drawable before using it in setError.

drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
editText.setError("error", drawable);
