Sudanese officials on Monday instead ordered Lubna Ahmed al-Hussein to pay a fine of about $200 following a court hearing in Khartoum, the Sudanese capital.
As al-Hussein made her way to the courtroom, scores of female supporters, some of them wearing trousers, rallied around her, some shouting: "Freedom, freedom!"
Police rounded many of them up and marched them away.
Asked about the verdict, al-Hussein said that she would refuse to pay the fine.
"I won't pay. I'd rather go to prison," al-Hussein told the AFP news agency by telephone following the trial.
Witnesses who attended the trial said the court had ruled she should be jailed for a month if she failed to pay. Her lawyers said they would try to persuade her.
Al-Hussein had faced a sentence of 40 lashes following her arrest for public indecency, alongside 12 other women, during a raid at a restaurant in Khartoum in July.
Ten of the women accepted a punishment of 10 lashes, but al-Hussein and two other women opted to go to trial.
