+ * \file android_utility/android_utility.h
+ * \brief Android utility.
+ *
+ * This class relies on a small utility wrapper shipped with the Android
+ * application to access to Java SDK APIs for information not available to
+ * native code.
+ *
+ * For instance, we currently don't have on Linux any mean to get the type
+ * associated to an interface, especially for cellular interfaces. WiFi and
+ * Bluetooth information is for instance available through specific netlink
+ * subsystems, or by means of a support library, but cellular detection mostly
+ * relies on heuristics based on interface names (eg. in network manager).
+ *
+ * Android ship a Radio Interface Layer (RIL) daemon that exposes a control
+ * socket to the Java API to control the radio layer, but there is no working
+ * code exploiting it and no proper documentation.
