From 4768f6316eca862996c5d15f8a54b79c8f54c8f7 Mon Sep 17 00:00:00 2001 From: Remi NGUYEN VAN Date: Tue, 26 Jan 2021 06:19:46 +0000 Subject: [PATCH] Revert "Revert "Note network interfaces based on transport"" Instead of classifying interfaces by network type in BatteryStats, classify them based on the transports array provided by the NetworkAgent. Network types are deprecated and transports should be used instead. This change allows BatteryStats to stop depending on unstable APIs such as isNetworkTypeMobile. This change also updates nullability annotations in ConnectivityService and NetworkAgentInfo to show that the NetworkCapabilities are non-null (as provided by the network agent) when calling noteNetworkInterfaceTransports. This is rolling forward a previously reverted change. The new change also fixes MobileRadioPowerCalculatorTest that was broken when submitting the previous change.
