一种手机卡槽与网络信号识别的Android实现

Implementation of Network Signal Recognition in Mobile Phone SIM-slot with Android System

利用基于SIM卡的ServiceState和SignalStrength等公开接口函数,通过特定的逻辑关联,达到网络信号的卡槽区分和识别的目的,实现了多卡槽终端的网络信号占用、信号质量提取功能,解决了Android系统不支持多卡槽的功能短板,并提供了基于Xamarin.Android的关键代码实现案例。

Making use of public APIs ServiceState&SiganalStrength based on SIM cardand via dedicated logical relat ionship,the network signal in mobile phone multi-SIM terminal with Android system can be distinguished.And RSRP/SINR from different SIM-slot can be extracted.The problem of non-supporting of multi-SIM terminal for Android system is solved and the implementation codes of Xamarin.Android is provided.
