文件修改说明:
device.mk: 在产品包中添加了红外服务的库文件和 APK 文件。Makefile.mt6735: 在 MediaTek 平台的驱动 Makefile 中添加了红外驱动的编译选项。Makefile: 创建了红外驱动的 Makefile 文件，用于编译红外驱动的源代码文件。irrx.c: 创建了红外驱动的源代码文件，实现了红外接收驱动的主要功能。irrx.h: 创建了红外驱动的头文件，定义了红外驱动的数据结构和接口。Android.mk: 创建了红外服务的 Makefile 文件，用于编译红外服务的 APK 文件和库文件。IrrxService.apk: 添加了红外服务的 APK 文件，这是一个 Android 应用，用于接收红外驱动的按键事件，并将其转发给其他应用。libserial_port.so: 添加了红外服务的库文件，这个库提供了串口通信的功能，用于接收红外信号。libserial_port.so: 添加了红外服务的库文件，这个库提供了串口通信的功能，用于接收红外信号。
