"Google's disregard for OEMs is legendary," Enderle said, adding that OEMs don't want to go public with their worries because they don't want to get into a fight with Google over security.
"We'll have to keep our fingers crossed that Google makes a greater focus on enterprise-grade features," added Ramon Llamas, an analyst at IDC. "Android is the biggest platform and has a big target on its back. There are tons of Android smartphones brought to jobs with BYOD, but a lot of enterprise groups are saying, 'Thanks, but no thanks' to Android and even with some Android apps.
"Google needs more smart security and enterprise support at the back end and greater communication with businesses," Llamas said.
Jack Gold, an analyst at J. Gold Associates, said that Google's May purchase of Divide, an enterprise software maker focused on BYOD, could lead to an announcement at I/O about enterprise support.
"Divide ultimately needs to be embedded into Android," Gold said. "Nevertheless, Google needs to make a strong statement that enterprise capabilities will be in the next release of Android and this would dramatically affect enterprise adoption of Android, which is limited now due to security concerns."
Google has declined to talk about what announcements will be made at I/O.
