Abstract method in non-abstract class?

I'm slightly confused here. While I was reading the API Documentation of some Android's classes, I found out that SpannableStringBuilder class contains an abstract method

abstract void drawText(Canvas c, int start, int end, float x, float y, Paint p)

while SpannableStringBuilder is a non-abstract class.

As I know , a non-abstract class can not contain an abstract method, and can not be instantiated. (SpannableStringBuilder can be instantiated as well) So what's the problem here?

 */
public void drawText(Canvas c, int start, int end,
                     float x, float y, Paint p) {
    checkRange("drawText", start, end);

    if (end <= mGapStart) {
