TelephonyManager是一个管理手机通讯状态、电话网路信息的服务类,该类提供了一个listen(PhoneStateListener listener,int events)方法来监听通话状态
运行上面的程序,可以在DDMS的File Explorer面板data/data/crazyit.monitorphone/files目录下看到一个phoneList文件,将改文件导入电脑可以看到来电电话信息
因为我是用真机测试,所以在DDMS下导出文件需要root权限,否则打不开文件夹
在DDMS取得打开文件夹的权限:
>adb shell
$ su
# chmod 755 /data
# chmod 755 /data/data
# chmod 755 /data/data/crazyit.monitorphone/
# chmod 755 /data/data/crazyit.monitorphone/files
