I am researching on Cellular connectivity in rural areas.
Is there an API in Android which helps you access Cellular radio properties as a call or SMS is made ?
P.S.: I am not looking for properties like signal Strength or Neighboring Cell Info. I am interested in listening to changes like in increase in CPU cycles, cellular handovers etc.
Edit:
My main reason for asking this is, so that I can detect events from different SIMs in Dual SIM phones as there is no current way of doing this. So by monitoring the radios, I can tell whether this was the SIM that made the call or the other.
