title: How does Modem code talk to Android code
body: <p>I would like to know high level idea of how Android Modem code will call/pass message to Android application layer. Say we take SMS for example. If network sends SMS and Modem (say Qualcomm C code parses it) how is it transmitted to Android Application layer?</p>
  
  <p>Is there always a JNI call happening? as interface between modem and Android? Can you please share the information with us. Thanks</p>
