Getting Runtime Information

-

The runtime information consists of key and value pairs.

Using Key-Value Pair

Some runtime information consists of key and value pairs.

To get information on, for example, whether Bluetooth is enabled or an audio jack connected:

  1. To use the functions and data types of the Runtime information API (in mobile and wearable applications), include the <runtime_info.h> header file in your application:

Using Function

Some runtime information can be gotten by using function.
