    @Override

        urlDrawable = new UrlImageDownloader(c.getResources(), source);

You haven't assigned a type to urlDrawable; This portion of code contains the error:

public class UILImageGetter implements Html.ImageGetter{
    Context c;
    TextView conatiner;
    urlDrawable;

Try this:

public class UILImageGetter implements Html.ImageGetter{
    Context c;
    TextView conatiner;
    UrlImageDownloader urlDrawable;

In which method should I do that? – Roseyk Apr 17 '16 at 16:23
right above this line: `public UILImageGetter(View textView, Context context) {` – iamkaan Apr 17 '16 at 16:30
At the top of your class after 'public class UILImageGetter implements Html.ImageGetter{' you have three variables. The bottom one. – ajohnston777 Apr 17 '16 at 16:30
Updated my answer to show the code that contains the error and the code you should use – ajohnston777 Apr 17 '16 at 16:38
Thanks, that fixed it. – Roseyk Apr 17 '16 at 17:18

Java is a strongly typed language, which means that all variables must be declared as being of some type.

Since you don't specify a type for urlDrawable, the compiler doesn't understand that you're declaring a variable.

Simply replace

urlDrawable;

with

UrlImageDownloader urlDrawable;

Should I do that for all instances of `urlDrawable` or just the first one? – Roseyk Apr 17 '16 at 16:36
You need to do it for every variable of type `URLImageDownloader` that you declare. I see that you're already doing it for `UrlImageDownloader mUrlImageDownloader;` for example. Of course you only have to do this when you [declare a variable](http://java.about.com/od/understandingdatatypes/a/declaringvars.htm), not when you use it! – Magnus Apr 17 '16 at 16:37
