基于Android的电话拨号功能

摘要

Android是一个开放性的平台,它具有非常丰富应用。将Android平台和电话联合起来研究,设计一个在Android平台上拨打和接听电话的应用,使Android平台具有电话拨号的功能。 Android平台和电话通过CD4052模拟开关组成的控制电路进行连接。通过在Android的Linux Kernel中编写驱动、在HAL和JNI中生成动态库、以及在应用层创建Application,实现Android系统电话拨号功能。经测试,设计的拨号应用能成功拨通号码。%Android is an open platform. It has very rich applications. This paper combines Android platform and telephone to study and design an application of making and receiving calls on the Android platform to make it has the function of telephone dialing. Android platform and telephone are connected by the control circuit with analog switches CD4052. The telephone dial-up function in Android system can be implemented by writing a driver in Linux kernel, generating dynamic libraries in JNI and HAL and creating application in the application layer. After testing, the design of the dial-up application can successfully dial the number.
