摘要
Abstract
Android is an open operating system based on the Linux Kernel,and it is widely used in a variety of mobile devices.This article combines the Android platform with the dial-up chip MT8880.Android native code supports very few devices,so we need to add a new low-level driver module in Linux Kernel,through the dynamic link libraries which are generated in the HAL layer and JNI layer,so that Android can identify a specific device MT8880,and control the logic output of MT8880.After loading the application,MT8880 chip can send Dual Tone Multi Frequency (DTMF) signal,finally realize Android system dial-up function.After testing,the dial-up driver can control the new device,the phone application can dial successfully.关键词
