app working in 2.3 but not in 4.2. why?
<p>I am working on a project that receives a signal on android via Bluetooth when car engine starts. Once android receives signal the mobile will go for silent mode and disconnect all the calls and then sends message to the caller. I tried it for Gingerbread, it's working. </p>

<p>But when i tried for jellybean, it failed. I have also mentioned the target version as 4.2. Everything except receiving Bluetooth signal is working fine. Something is wrong with Bluetooth part.  Please help me so that it works for 4.2 too</p>
