Prosecutors had sought to have 13 other accusers testify in Constand's case, but the judge allowed only one, finding that more would unfairly prejudice the jury.
Mr Cosby, 79, was tried for drugging and sexually assaulting Andrea Constand in 2004.
The prosecutor, Kevin Steele, says he will retry Bill Cosby.
The mistrial was a blow to the dozens of women who have said they were sexually assaulted by Cosby, including several who attended the trial wearing buttons that read "We Stand in Truth".

"How do I describe the counsels for the accusers?"
According to onlookers, Bill Cosby compared his plight to that of Nelson Mandela on Robinson Island, telling those around him about the time he and his wife, Camille, met the South African icon.

Confidential informants had helped ID the suspects and alleged the killings were revenge for the robbery, he added. According to police, it was the last communication Najjar had with anyone, about a half-hour before he was killed.
The jury appeared unable to agree on which version of the night in question to believe: Constand's or Cosby's.
Cosby's team declared victory, however temporary. "Power is the ability to defy phenomenon, making it act in a desired manner", said his long-time publicist Andrew Wyatt.
The verdict came five days after spirited closing arguments in which Cosby was alternately portrayed as a man so intent on having sex with Constand that he used drugs to render her incapacitated, and as a man who had been framed by Constand and others in hopes of reaping monetary settlements in civil suits.
Cosby's defense lawyers, however, argued that Constand's account could not be trusted after they pointed to numerous discrepancies in her statements to police in 2005, when she first reported the encounter, which occurred almost a year earlier.
Cosby, who gave the deposition as part of Constand's lawsuit against him, said he got seven prescriptions for the powerful sedative in the 1970s for the goal of giving them to women with whom he wanted to have sex.
She filed a lawsuit that Cosby settled for an undisclosed sum. Constand told the jury she was merely returning his calls about the women's basketball squad at Temple University, where she was director of team operations and he was a member of the board of trustees.
The jurors clearly struggled with their verdict, telling Judge Steven O'Neill on Thursday they were at impasse. It must come to a unanimous decision to convict or acquit. The judge has refused, saying jurors are permitted under the law to deliberate as long as they want.
Cosby is charged with three counts of aggravated indecent assault that could put him in prison for the rest of his life.
The jury failed to reach a unanimous decision on any of the three counts against the comedian, ending the trial without a verdict. Comedian Aparna Nancherla, who frequently posts social commentary, tweeted, "Ask women again why they don't report their rapes".
The jurors will get back to work Saturday morning. He maintains it was consensual. Cosby and Constand will likely return to court within a year.
"This case is about a drug-facilitated sexual assault and it doesn't matter what you look like or who you are".
