The three felony charges net the possibility of 34 years in prison and $50,000 in fines, the release said.
A preliminary hearing has been scheduled for June 1 before Magisterial District Judge Joseph Lindsey in Harrisburg. He was jailed in lieu of $250,000 bail.
Corbett said Doyle's home was being searched in the investigation.
Doyle, under the Yahoo! screen name "bdoyle4u," allegedly proposed the meeting and asked the agent a series of sexual questions earlier this month, the release said. He said he was available after school, according to a criminal complaint from the case.
He used a Web cam to transmit naked images of himself, according to the complaint.
The release also detailed the arrest of a Lancaster County, Pa., man who allegedly "described in detail the sex acts he wished to perform with what he believed was a 12-year-old girl."
Brian K. Nolt, 46, of 1401 Cloverton Drive, Columbia, Pa., allegedly sent 40 pornographic photographs and videos to an agent, while also proposing a meeting, the release said.
He was arrested Sunday in Elizabethtown, Pa., and has been charged with one count of criminal solicitation of unlawful contact with a minor, one count of criminal use of a communication facility and 40 counts of criminal attempt obscene performances, according to the release.
The release said Nolt was jailed in Lancaster County Prison in lieu of $250,000 bail.
Corbett said the investigations are part of a "continuing, proactive undercover investigation" by the attorney general's office to identify and capture Internet child predators before they harm children. He said in a news release that Nolt and Doyle's arrests are the 47th and 48th arrests since the Child Predator Unit was created in January 2005.
