Open android Front camera and Back camera at the same time

I want to receive data from front camera and back at the sam开发者_运维问答e time on Android 2.3.3. Can I use two cameras at the same time and receive data by onPreviewFrame ?

Or another way to get data from two cameras at the same time ?

Thanks.

What I read in API 2.3 for multiple cameras selection, only one camera at the same time can be open. So officialy not, but there can be some kind of hack maybe.
